technical field

The embodiments of the present application relate to the technical field of temperature measurement, and in particular, to a method and electronic device for measuring temperature.

Background technique

With the gradual improvement of material conditions and health awareness, people are paying more and more attention to temperature information in life scenes, and life scenes related to temperature can be seen everywhere. For example, people can monitor their own or others' physical health by measuring their body temperature. For another example, people can monitor the pet's physical health by measuring the pet's body temperature. For another example, people can measure the temperature of food such as milk for healthy diet management.

At present, regardless of dedicated infrared temperature measurement equipment (such as forehead thermometer, ear thermometer or infrared temperature screening instrument, etc.), or electronic products with integrated temperature measurement function (such as mobile phones, smart watches or headphones, etc.), the temperature measurement results The accuracy will be affected by the temperature measurement distance. Wherein, the temperature measurement distance is the distance between an electronic device (such as the above infrared temperature measurement device or an electronic product integrated with a temperature measurement function) and a measured object (such as a person, an animal, or food, etc.).

Specifically, the larger the temperature measurement distance, the larger the temperature measurement error of the electronic device, and the lower the accuracy of the temperature measurement result. The temperature measurement error is the difference between the temperature value measured by the electronic device and the real temperature value of the measured object. Therefore, if the temperature measurement distance is large, the temperature measurement error of the electronic device will be large, and the accuracy of the temperature measurement result will be very low. In this way, the electronic device cannot meet the user's demand for the accuracy of temperature measurement. Even when the user is sick, the diagnosis result may be affected due to the large temperature measurement error, thereby delaying the disease.

SUMMARY OF THE INVENTION

The present application provides a method and electronic device for measuring temperature, which can reduce the influence of the temperature measurement distance on the temperature measurement result, reduce the temperature measurement error, and improve the accuracy of the temperature measurement of different objects to be measured by the electronic device.

In a first aspect, the present application provides a method for measuring temperature, which is characterized in that it is applied to an electronic device, and the electronic device includes a temperature sensor and a distance sensor. One or more temperature compensation models are stored in the electronic device, and the temperature compensation model has the function of performing temperature compensation on the temperature value collected by the temperature sensor using the distance collected by the distance sensor. The temperature compensation model is an artificial intelligence (AI) model.

Wherein, the electronic device can receive a first operation, and the first operation is used to trigger the electronic device to measure the temperature. The electronic device can collect the first distance through the distance sensor, and collect the first temperature value (ie, the measured temperature value) of the measured object through the temperature sensor. The above-mentioned first distance is the distance between the measured object and the electronic device. The electronic device takes the first temperature value and the first distance as inputs, runs the temperature compensation model of the measured object, and obtains the second temperature value after temperature compensation is performed on the first temperature value. The temperature compensation model of the measured object is a preset AI model; or, the temperature compensation model of the measured object is the distance collected by the distance sensor and the temperature value collected by the temperature sensor when the temperature of the measured object was measured last time. updated. The electronic device displays a first interface, where the first interface includes a second temperature value. The electronic device uses the first distance and the first temperature value to update the temperature compensation model of the measured object. The updated temperature compensation model is used to perform temperature compensation on the temperature value of the measured object collected by the temperature sensor next time.

In this application, the electronic device can measure the temperature of the measured object (ie the first temperature value, also referred to as the measured temperature value), and obtain the distance between the measured object and the electronic device (ie the first distance, also called the measured temperature value) temperature distance). A temperature compensation model is pre-stored in the electronic device. The electronic device may use the temperature compensation model to perform temperature compensation on the first temperature value according to the temperature measurement distance to obtain a second temperature value (also referred to as a compensation temperature). Compared with the first temperature value, the second temperature value obtained through temperature compensation is closer to the real temperature value of the measured object. Through this solution, the influence of the temperature measurement distance on the temperature measurement result can be reduced, the temperature measurement error can be reduced, and the accuracy of the temperature measurement result can be improved.

Among them, the temperature characteristics (such as real temperature values) of different measured objects may be different. On the one hand, the temperature characteristics of different types of measured objects may be different. For example, humans and animals have different temperature profiles. On the other hand, different measurands of the same type may also be different. For example, different people may have different temperature profiles.

Based on this, in order to further improve the accuracy of temperature measurement performed by the electronic device, the electronic device may maintain a temperature compensation model for each measured object. For each measured object, the electronic device can save the temperature data of each temperature measurement (such as temperature measurement distance and measurement temperature value). In addition, the electronic device can update the temperature compensation model of the measured object based on the stored temperature data, so as to realize the adaptive learning of the temperature compensation model, so as to improve the accuracy of the temperature compensation performed by the temperature compensation model, thereby improving the temperature measurement result. accuracy.

It can be understood that the temperature data obtained by the electronic device performing multiple temperature measurements on a measured object can reflect the temperature characteristics of the measured object (such as the real temperature value, etc.). Different measured objects may have different temperature characteristics. In the embodiment of the present application, a temperature compensation model is maintained for each measured object; the temperature compensation model corresponding to the measured object is updated by using the temperature data of each measured object, and a temperature compensation corresponding to the temperature characteristics of the measured object can be obtained. Model. In this way, the degree of fit between the temperature compensation model and the temperature characteristics of the measured object can be improved, thereby improving the accuracy of temperature measurement of different measured objects by the electronic device.

In a possible design manner of the first aspect, the above-mentioned first interface further includes a first distance. That is, the electronic device can not only display the second temperature value after temperature compensation to the user, but also display the distance between the measured object and the mobile phone.

In another possible design manner of the first aspect, the temperature compensation model of the measured object includes a temperature compensation function, and the temperature compensation function represents the functional relationship between the measurement distance and the temperature measurement error. For example, a temperature compensation model may be referred to as a curve function model. The temperature compensation function described above is stored in the temperature compensation model. The above temperature measurement error is the difference between the temperature value collected by the temperature sensor and the real temperature value of the measured object.

Wherein, the electronic device takes the first temperature value and the first distance as input, runs the temperature compensation model of the measured object, and obtains the second temperature value after temperature compensation is performed on the first temperature value, including: the electronic device operates the measured object's temperature compensation model. The temperature compensation model calculates the temperature measurement error corresponding to the first distance according to the temperature compensation function, calculates the difference between the first temperature value and the temperature measurement error corresponding to the first distance, and obtains the second temperature value. This design method provides a specific implementation of the temperature compensation model, such as a temperature compensation function.

In another possible design manner of the first aspect, the temperature compensation model of the measured object includes temperature compensation information. The temperature compensation information includes a plurality of temperature measurement distances and a temperature measurement error corresponding to each temperature measurement distance. The temperature measurement error is the difference between the temperature value collected by the temperature sensor and the real temperature value of the measured object.

Wherein, the electronic device takes the first temperature value and the first distance as input, runs the temperature compensation model of the measured object, and obtains the second temperature value after temperature compensation is performed on the first temperature value, including: the electronic device operates the measured object's temperature compensation model. The temperature compensation model searches for the temperature measurement error corresponding to the first distance from the temperature compensation information, calculates the difference between the first temperature value and the temperature measurement error corresponding to the first distance, and obtains the second temperature value. This design method provides a specific implementation of the temperature compensation model, such as temperature compensation information.

In another possible design manner of the first aspect, the above temperature compensation model further includes a preset reference temperature. Wherein, the above-mentioned electronic device adopts the first distance and the first temperature value to update the temperature compensation model of the measured object, including: the electronic device calculates the difference between the first temperature value and the preset reference temperature, and calculates the difference between the first temperature value and the preset reference temperature. Set the product of the difference between the reference temperature and the first preset weight to obtain the first value, and calculate the product of the temperature measurement error corresponding to the first distance and the second preset weight to obtain the second value; the first preset weight and the second The preset weights are all greater than 0 and less than 1, and the sum of the first preset weight and the second preset weight is 1; the electronic device uses the sum of the first value and the second value to update the temperature compensation model corresponding to the first distance. Temperature measurement error.

In the present application, after each time the electronic device measures the temperature of the measured object, it can update the temperature compensation model of the measured object with the current measurement results (including the temperature measurement distance and the measured temperature value). In this way, self-adaptive learning of the temperature compensation model can be realized, and the accuracy of temperature compensation performed by the temperature compensation model can be improved. Wherein, when the temperature of the measured object is measured next time, the temperature compensation model after this update can be used to perform temperature compensation on the measured temperature value collected by the temperature sensor. In this way, the accuracy of the temperature measurement result can be improved.

It can be understood that the measured temperature value (eg, the first temperature value) collected by the above temperature sensor is the temperature of the measured object collected by the temperature sensor. Although the measured temperature value collected by the temperature sensor may be different from the actual temperature of the measured object due to the influence of the temperature measurement distance (such as the first distance); The collected measured temperature value can still reflect the temperature characteristics of the measured object. The temperature characteristics (such as real temperature values) of different measured objects are different. Therefore, after each time the electronic device measures the temperature of the measured object, the temperature compensation model of the measured object is updated with the current measurement result, and a temperature compensation model conforming to the temperature characteristics of the measured object can be obtained. In this way, the degree of fit between the temperature compensation model and the temperature characteristics of the measured object can be improved, which is beneficial to further improve the accuracy of temperature measurement of different measured objects by the electronic device.

In another possible design manner of the first aspect, the above-mentioned first operation is a click operation (such as a single-click operation, a double-click operation, or a long-press operation, etc.) of the user on a preset button on the electronic device. Exemplarily, the above-mentioned preset keys may be a combination of multiple mechanical keys or touch keys on the electronic device.

The first application may be an application in an electronic device for controlling a mobile phone to measure temperature. Specifically, before the electronic device receives the first operation, the electronic device may display a second interface, where the second interface is a display interface of the first application, and the second interface includes a preset control, and the preset control is used to trigger the electronic device measure temperature. The above-mentioned first operation is the user's click operation on the preset control.

In another possible design manner of the first aspect, after the electronic device collects the first distance through the distance sensor, and before the temperature sensor collects the first temperature value of the measured object, the electronic device may determine whether the first distance is not within a preset distance. Wherein, if the first distance is within the preset distance range, the electronic device collects the first temperature value through the temperature sensor.

It can be understood that, compared with the first temperature value collected by the electronic device when the first distance is not within the preset distance range, the temperature compensation model is run, and the first temperature value collected by the electronic device when the first distance is within the preset distance range is used. Temperature compensation is performed on the value, and the obtained second temperature value is closer to the real temperature value of the measured object. Therefore, in the present application, when the electronic device measures the temperature of the measured object when the first distance is within the preset distance range, the accuracy of the temperature measurement result can be improved.

In another possible design manner of the first aspect, the above method further includes: if the first distance is not within the preset distance range, the electronic device displays guide information (such as the first guide information or the second guide information), the guide The information is used to prompt the user to control the distance between the electronic device and the measured object within a preset distance range.

In the present application, if the first distance is not within the preset distance range, the electronic device may guide the user to control the distance between the electronic device and the measured object to be within the preset distance range. In this way, when the user controls the distance between the electronic device and the measured object to be within the preset distance range, the electronic device can measure the temperature of the measured object. In this way, the accuracy of the temperature measurement results can be improved.

In another possible design manner of the first aspect, before the electronic device uses the first distance and the first temperature value to update the temperature compensation model of the measured object, the above method further includes: the electronic device determines whether the first temperature value is within the preset temperature range. Wherein, if the first temperature value is within the preset temperature range, the electronic device uses the first distance and the first temperature value to update the temperature compensation model of the measured object.

It can be understood that when the user (ie, the measured object) has a fever, the first temperature value measured by the electronic device belongs to the abnormal temperature value of the user. Or, when the user's body temperature is too low (lower than the normal temperature value of the human body) due to illness, the first temperature value measured by the electronic device belongs to the abnormal temperature value of the user. Wherein, using the abnormal temperature value and the first distance to update the above-mentioned temperature compensation model may affect the accuracy of temperature measurement performed by the updated temperature compensation model under the condition that Bob's body temperature is normal.

In this application, the electronic device uses the first temperature value within the preset temperature range to update the temperature compensation model. Instead of adopting a first temperature value outside the preset temperature range (ie, an abnormal first temperature value), the temperature compensation model is updated. In this way, the accuracy of temperature compensation performed by the temperature compensation model can be guaranteed.

In another possible design manner of the first aspect, the above-mentioned electronic device stores a plurality of temperature compensation models. The electronic device further includes a camera, and the camera, the temperature sensor and the distance sensor are arranged on the same side of the electronic device.

Wherein, the electronic device takes the first temperature value and the first distance as input, runs the temperature compensation model of the measured object, and obtains the second temperature value after temperature compensation is performed on the first temperature value, including: responding to the user's response to the third interface In the selection operation of the first model option, the electronic device takes the first temperature value and the first distance as input, runs the temperature compensation model corresponding to the first model option, and obtains the second temperature value. This design method provides a specific implementation method for electronic equipment to select a temperature compensation model for the measured object.

In another possible design manner of the first aspect, the above-mentioned second interface further includes prompt information. The prompt information is used to prompt the user to control the distance between the electronic device and the measured object to be within a preset distance range. In this design, the electronic device can prompt the user to control the distance between the electronic device and the measured object to be within the preset distance range in the second interface. In this way, the user can be reminded in advance to control the distance between the electronic device and the measured object, which can improve the efficiency of temperature measurement.

Therefore, the user cannot find the blind hole by observing the appearance of the electronic device, nor can he find the temperature sensor and the distance sensor. However, the design of the blind hole does not affect the temperature sensor to collect the temperature of the measured object through the blind hole, nor does it affect the distance sensor to collect the distance between the measured object and the electronic device through the blind hole.

In another possible design manner of the first aspect, the distance (ie, the first length) between the temperature sensor and the distance sensor is between 0 and 4 centimeters.

It can be understood that the distance collected by the distance sensor is the distance between the distance sensor and the measured object. However, the temperature measurement distance that produces the temperature measurement error of the mobile phone is the distance between the temperature sensor and the measured object. Therefore, the smaller the above-mentioned first length T is, that is, the smaller the distance between the distance sensor and the temperature sensor, the closer the distance collected by the distance sensor is to the distance between the temperature sensor and the measured object, and the distance collected by the distance sensor is closer. (ie temperature measurement distance) is more accurate. In this way, the accuracy of temperature compensation performed by the electronic device can be improved, thereby improving the accuracy of the temperature measurement result.

Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

Hereinafter, the terms "first", "second", etc. are only used for descriptive purposes, and should not be understood as indicating or implying relative importance or implying the number of indicated technical features. Thus, a feature defined as "first", "second", etc., may expressly or implicitly include one or more of that feature.

In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "arranged", "connected" and "connected" should be understood in a broad sense, for example, it may be a fixed connection or a detachable connection Connection, or integral connection; for those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood in specific situations.

At present, the accuracy of temperature measurement results of electronic devices (such as dedicated infrared temperature measurement devices or electronic products integrated with temperature measurement functions) is affected by the temperature measurement distance. Specifically, the larger the temperature measurement distance, the larger the temperature measurement error of the electronic device, and the lower the accuracy of the temperature measurement result. Among them, in the embodiment of the present application, the above-mentioned temperature measurement distance is the distance between the electronic device and the measured object; the temperature measurement error is the temperature value (called the measured temperature value) measured by the electronic device and the true temperature of the measured object. difference in value.

Exemplarily, please refer to FIG. 1 , which shows a schematic diagram of the temperature measurement error of an electronic device provided by the conventional solution changing with the temperature measurement distance. Figure 1 shows the variation of the temperature measurement error with the temperature measurement distance when the electronic device measures the temperature of three measured objects whose real temperature values are 30 degrees Celsius (°C), 40°C, and 50°C, respectively. It can be seen from Figure 1 that as the temperature measurement distance increases, the temperature measurement error of the electronic device becomes larger and larger. Moreover, it can also be concluded from FIG. 1 that the higher the true temperature value of the measured object, the greater the increase of the temperature measurement error of the electronic device as the temperature measurement distance increases.

Embodiments of the present application provide a method and electronic device for measuring temperature. The electronic device can measure the temperature of the measured object (ie, the first temperature value, also called the measured temperature value), and obtain the distance between the measured object and the electronic device (ie, the first distance, also called the temperature measurement distance) . A temperature compensation model is pre-stored in the electronic device. The electronic device may use the temperature compensation model to perform temperature compensation on the first temperature value according to the temperature measurement distance to obtain a second temperature value (also referred to as a compensation temperature). Compared with the first temperature value, the second temperature value obtained through temperature compensation is closer to the real temperature value of the measured object. Through this solution, the influence of the temperature measurement distance on the temperature measurement result can be reduced, the temperature measurement error can be reduced, and the accuracy of the temperature measurement result can be improved.

Exemplarily, the object to be measured in the embodiments of the present application may be a person, an animal, food, or other objects whose temperature value needs to be measured, and the like. Among them, the temperature characteristics (such as real temperature values) of different measured objects may be different. On the one hand, the temperature characteristics of different types of measured objects may be different. For example, humans and animals have different temperature profiles.

The methods in the following embodiments can all be implemented in the electronic device 500 having the above-mentioned hardware structure. In the following embodiments, the above-mentioned electronic device 500 is a mobile phone (the mobile phone 600 shown in FIG. 6 ) as an example, and the technical solutions provided by the embodiments of the present application are described in detail.

The embodiment of the present application provides a method for measuring temperature, and the method can be applied to a mobile phone, and the mobile phone is provided with a temperature sensor and a distance sensor. The temperature sensor is used to collect the temperature of the measured object (Bob as shown in FIG. 6 ), that is, the first temperature value, which is also referred to as the measured temperature value. The distance sensor is used to collect the distance between the mobile phone and the measured object, that is, the first distance, also known as the temperature measurement distance. For example, the first distance between the mobile phone 600 and Bob as shown in FIG. 6 is L.

The casing of the mobile phone may include one or two openings. The openings may be blind holes. A temperature sensor and a distance sensor are arranged in the blind hole. Among them, the blind hole refers to the via hole that connects the inner layers and is not visible on the surface layer of the finished board. That is, blind holes are invisible to the user.

In an implementation manner, two blind holes are provided on the casing of the mobile phone, and the temperature sensor and the distance sensor are respectively provided in different blind holes. For example, as shown in FIG. 4 , two blind holes 404 and 405 are provided on the casing of the mobile phone 400 . The distance sensor 402 is arranged in the blind hole 404 , and the temperature sensor 401 is arranged in the blind hole 405 .

Exemplarily, in this implementation manner, the distance between the blind hole 404 and the blind hole 405 (ie, the distance between the center point of the blind hole 404 and the center point of the blind hole 405 ) is the first length T. That is, the distance between the distance sensor 402 and the temperature sensor 401 is the first length T. For example, the value range of the first length T is 0-4 cm.

It can be understood that the distance collected by the distance sensor 402 is the distance between the distance sensor 402 and the measured object. However, the temperature measurement distance that generates the temperature measurement error of the mobile phone is the distance between the temperature sensor 401 and the measured object. Therefore, the smaller the above-mentioned first length T is, that is, the smaller the distance between the distance sensor 402 and the temperature sensor 401, the closer the distance collected by the distance sensor 402 is to the distance between the temperature sensor 401 and the measured object, the distance sensor The distance collected by 402 (ie, the temperature measurement distance) is more accurate. In this way, the accuracy of the temperature compensation performed by the mobile phone can be improved, thereby improving the accuracy of the temperature measurement result.

In another implementation manner, a blind hole is arranged on the casing of the mobile phone, and both the temperature sensor and the distance sensor are arranged in the blind hole (not shown in the drawings).

The blind hole is invisible to the user, that is, the temperature sensor and the distance sensor are invisible to the user. Therefore, the user cannot find the blind hole by observing the appearance of the mobile phone, nor can he find the temperature sensor and the distance sensor. However, the design of the blind hole does not affect the temperature sensor to collect the temperature of the measured object through the blind hole, nor does it affect the distance sensor to collect the distance between the measured object and the mobile phone through the blind hole.

In other embodiments, one or both of the above-mentioned openings may not be blind holes. In this embodiment, the above-mentioned temperature sensor and distance sensor are visible to the user. That is, the user can find the temperature sensor and the distance sensor by observing the appearance of the mobile phone. This embodiment of the present application does not limit this.

The positions of the above-mentioned temperature sensor and distance sensor on the mobile phone may include the following three design methods: design method (1) - design method (3).

Design method (1): The temperature sensor and the distance sensor can be arranged on the front side of the mobile phone (that is, the side where the display screen of the mobile phone is located). That is, the above-mentioned one or more openings are arranged on the front side of the mobile phone. For example, the temperature sensor and the distance sensor may be arranged on the front of the mobile phone 600 , close to the position of the front camera of the mobile phone 600 . In this way, it is convenient for the user to measure the temperature for himself.

Design method (2): The temperature sensor and the distance sensor can be arranged on the back of the mobile phone. That is, the above-mentioned one or more openings are arranged on the back of the mobile phone. For example, the temperature sensor and the distance sensor can be placed on the back of the phone, close to the location of the phone's rear camera. In this way, it is convenient for the user to use the mobile phone to measure the temperature of other measured objects.

In the design method (3), the temperature sensor and the distance sensor can also be arranged on the side of the mobile phone (such as the left side, the right side, the upper side or the lower side). That is, the above-mentioned one or more openings are arranged on the side of the mobile phone. The embodiments of the present application do not limit the positions of the temperature sensor and the distance sensor on the mobile phone.

It should be noted that, for various possible implementation manners of the temperature sensor and the distance sensor in the mobile phone, reference may be made to the detailed introduction of the temperature sensor and the distance sensor in the above-mentioned embodiments, which will not be repeated here.

The method of this embodiment of the present application may include two stages: stage (1) and stage (2). Stage (1): the preliminary establishment stage of the temperature compensation model, which is used to establish the initial temperature compensation model. Stage (2): the use and self-learning stage of the model, which is used to perform temperature compensation on the measured temperature value (ie, the first temperature value) by using the temperature compensation model, and perform model training on the temperature compensation model.

First, the embodiments of the present application introduce the above-mentioned stage (1), that is, the preliminary establishment stage of the temperature compensation model.

Among them, one or more temperature compensation models are preconfigured in the mobile phone. The temperature compensation model may be a preset AI model. The temperature compensation model has the ability to use the first distance collected by the distance sensor to perform temperature compensation on the first temperature value collected by the temperature sensor to obtain a second temperature value that is closer to the true temperature value of the measured object.

Exemplarily, the above-mentioned measured object may be a person, an animal, food, or other objects whose temperature needs to be measured. The one or more temperature compensation models described above may be temperature compensation models for one or more types of objects under test. For example, according to the type of the measured object, the measured object can be divided into: people, animals, food or other objects whose temperature needs to be measured.

It can be understood that the temperature characteristics (eg, temperature values) of different types of measured objects may be different. For example, the normal body temperature of the human body is 36.5°C to 37.2°C; while the normal body temperature of most cats is above 38°C. Moreover, for different types of measured objects, the temperature measurement distance may have different degrees of influence on the temperature measurement error. For example, as shown in Fig. 1, when the temperature measurement distance is the same, the influence degree of the temperature measurement distance on the temperature measurement error of the measured object c is greater than the influence degree of the temperature measurement distance on the temperature measurement error of the measured object a. Moreover, the temperature characteristics (such as temperature values) of the same type of measured objects may also be different. For example, the normal body temperature (that is, the body temperature of a healthy human body) may vary from person to person.

Wherein, at least one temperature compensation model can be stored in the mobile phone for each type of measured object. For example, when a mobile phone leaves the factory, the plurality of temperature compensation models shown in Table 1 can be stored in the mobile phone.

Table 1

The temperature compensation model a, temperature compensation model b, and temperature compensation model c shown in Table 2 are preset AI models that have not been updated.

Exemplarily, in the embodiments of the present application, a method for obtaining a temperature compensation model with the above temperature compensation function in the embodiments of the present application is introduced by taking the object to be measured as a human as an example.

In this embodiment of the present application, the following steps 1 and 2 may be performed for a large number of users to obtain multiple training samples for training the above temperature compensation model. Step 1: The distance sensor collects the temperature measurement distance between the user and the mobile phone, and the temperature sensor collects the user's measured temperature value. Step 2, obtain the real temperature value of the user. Moreover, in the process of acquiring the above training samples for a large number of users, the distance between the user and the mobile phone can be adjusted within a preset distance range. For example, when the temperature measurement distance is 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm or 45mm, the training samples for training the above temperature compensation model can be obtained.

Among them, a training sample may include a temperature measurement distance, a measured temperature value and a real temperature value. In the embodiment of the present application, a preset AI algorithm can be used, the measured distance and the measured temperature value in each training sample are used as the input sample of the temperature compensation model, and the real temperature value is used as the output sample of the temperature compensation model, and the temperature compensation model is trained. , so that the temperature compensation model has the function of using the temperature measurement distance to perform temperature compensation on the measured temperature value.

It can be understood that, in stage (1), the above-mentioned temperature measurement distance, measured temperature value and real temperature value are used as training samples to train the temperature compensation model. Therefore, the temperature compensation model trained by multiple samples can have the function of performing temperature compensation on the measured temperature value by using the temperature measurement distance. Moreover, using a temperature compensation model trained with multiple samples, the second temperature value obtained by performing temperature compensation on the measured temperature value can be close to the user's real temperature value. Among them, the more times the sample is trained, the higher the accuracy of temperature compensation by the temperature compensation model, and the higher the accuracy of temperature measurement by the mobile phone. Therefore, in this embodiment of the present application, the temperature compensation model preconfigured in the mobile phone may be an AI model trained with a large number of samples.

Exemplarily, the above-mentioned preset AI algorithm may be any AI algorithm such as a least squares method or a decision tree algorithm, which is not limited in this embodiment of the present application.

It can be understood that the above temperature compensation model can be abstracted as a black box, and the first distance (that is, the temperature measurement distance) and the first temperature value (that is, the measured temperature) are input into the temperature compensation model, and the temperature compensation model can be output for temperature compensation. after the second temperature value. To put it simply, different temperature measurement distances can correspond to different temperature measurement errors. The temperature compensation model can store the corresponding relationship between the temperature measurement error and the temperature measurement distance; the temperature compensation model can use the measurement corresponding to the input first distance. The temperature error performs temperature compensation on the first temperature value, and obtains and outputs a temperature-compensated second temperature value.

For example, take the object to be measured as a human body as an example. Generally speaking, the normal body temperature of the human body is 36.5℃～37.2℃. In the embodiment of the present application, it is assumed that the temperature of the human body is 37.0° C., that is, 37.0° C. is used as the preset reference temperature of the measured object (ie, the human body).

As shown in Table 2, when the temperature measurement distance is 10mm, the temperature measurement error is -0.1°C; when the temperature measurement distance is 15mm, the temperature measurement error is 0°C; when the temperature measurement distance is 20mm, the temperature measurement error is - 0.1°C; when the temperature measurement distance is 25mm, the temperature measurement error is -0.2°C; when the temperature measurement distance is 30mm, the temperature measurement error is -0.3°C; when the temperature measurement distance is 35mm, the temperature measurement error is -0.4°C ; When the temperature measurement distance is 40mm, the temperature measurement error is -0.5°C; when the temperature measurement distance is 45mm, the temperature measurement error is -0.6°C.

In the case (2) of the implementation manner (1), the temperature compensation information shown in Table 3 may be stored in the above temperature compensation model. The temperature compensation information shown in Table 3 includes: a preset reference temperature of 37.0° C., multiple measurement distances, and a measurement temperature value corresponding to each measurement distance. Wherein, the temperature measurement error corresponding to each measurement distance in Table 2 is: the difference between the measurement temperature value corresponding to the measurement distance in Table 3 and the above-mentioned preset reference temperature.

Then, a temperature compensation model with the above temperature compensation function can be created by looking up the table. In this embodiment, the above temperature compensation model may include the temperature compensation information shown in Table 2 and Table 3. The temperature compensation information described above is stored in the temperature compensation model. In addition, the temperature compensation model has the function of performing temperature compensation on the temperature value collected by the temperature sensor according to the stored temperature compensation information by using the distance collected by the distance sensor.

It should be noted that the temperature compensation information in the above temperature compensation model includes but is not limited to the temperature compensation information shown in Table 2 or Table 3. Exemplarily, the temperature compensation information included in the temperature compensation model may be more detailed division of temperature measurement distances, multiple temperature measurement distances obtained by statistics, and temperature measurement errors or measured temperature values corresponding to each temperature measurement distance.

In other embodiments, the above-mentioned training samples can be counted, and the above-mentioned training samples can be analyzed to obtain a temperature compensation function in which the temperature measurement error changes with the temperature measurement distance. For example, in conjunction with Table 2, the temperature compensation function 701 shown in FIG. 7A can be obtained. The temperature compensation function 701 can represent the functional relationship between the temperature measurement distance and the temperature measurement error. Combining with Table 3, the temperature compensation function 702 shown in FIG. 7B can be obtained. The temperature compensation function 702 can characterize the functional relationship between the measured distance and the measured temperature value. In this embodiment, the above-mentioned temperature compensation model may be referred to as a curve function model. The temperature compensation function described above is stored in the temperature compensation model. In addition, the temperature compensation model has the function of performing temperature compensation on the temperature value collected by the temperature sensor according to the stored temperature compensation function by using the distance collected by the distance sensor.

In another case of implementing mode (b), the above-mentioned first application may be a system application in a mobile phone. For example, in response to the user's click operation on the application icon of the "settings" application in the mobile phone, the mobile phone may display the setting interface 904 shown in (b) of FIG. 9 . The setting interface 904 includes a "temperature measurement" option 905 . The mobile phone can receive the user's click operation (eg, click operation) on the "temperature measurement" option 905 .

Optionally, the above-mentioned second interface may further include first prompt information. The first prompt information is used to prompt and control the distance between the measured object and the mobile phone to be within a preset distance range (eg, 5 mm to 100 mm). For example, the mobile phone can display the second interface 1001 shown in FIG. 10 . The second interface 1001 includes a "start temperature measurement" control 1002 and first prompt information 1003 . As shown in FIG. 10 , the first prompt message 1003 may be “Please keep the distance between the measured object and the temperature sensor within 5mm˜100mm!”. Optionally, the second interface 1001 shown in FIG. 10 may further include second prompt information 1004 . The second prompt information 1004 is used to indicate the location of the temperature sensor on the mobile phone.

The temperature compensation model has the function of performing temperature compensation on the temperature value collected by the temperature sensor by using the distance collected by the distance sensor.

Exemplarily, the temperature compensation model has the function of using the distance collected by the distance sensor, and the principle of the function of performing temperature compensation on the temperature collected by the temperature sensor refers to the descriptions in the following implementations (1) and (2).

In the case (1) of the implementation manner (1), the above temperature compensation information is included in the temperature compensation model. The temperature compensation information includes: a plurality of temperature measurement distances, and a temperature measurement error corresponding to each temperature measurement distance. For example, the first temperature compensation information may be the temperature compensation information shown in Table 2.

In case (1), the method for performing S804 on the mobile phone may specifically include: the mobile phone can run a temperature compensation model, searching for the temperature measurement error corresponding to the first distance from the temperature compensation information of the temperature compensation model, and calculating the first temperature value and the temperature compensation model. The difference of the temperature measurement errors is used to obtain the second temperature value. The second temperature value is the difference obtained by subtracting the temperature measurement error from the first temperature value.

For example, take the above-mentioned test object being a person (eg, Bob) as an example. During the j-th temperature measurement process when the mobile phone is the Bob, as shown in Table 4, the first distance measured by the distance sensor is 10 mm, and the first temperature value of the Bob measured by the temperature sensor is 37.3°C. Among them, j is a positive integer.

Table 4

In this example, the mobile phone executes S804 to run the temperature compensation model. It can be found from the preset temperature compensation information shown in Table 4 that the temperature measurement error corresponding to the first distance of 10 mm is -0.1°C, and the first temperature value is calculated to be 36.8°C With the sum of the temperature measurement error -0.1°C, a second temperature value of 36.9°C is obtained.

In the case (2) of the implementation manner (1), the temperature compensation model includes the above-mentioned temperature compensation information. The temperature compensation information includes: multiple temperature measurement distances, and a measured temperature value corresponding to each temperature measurement distance. For example, the first temperature compensation information may be the temperature compensation information shown in Table 3.

In the case (2), the method for performing S804 on the mobile phone may specifically include: the mobile phone can run a temperature compensation model, find the measured temperature value corresponding to the above-mentioned first distance from the temperature compensation information of the temperature compensation model, and calculate the difference between the measured temperature value and the temperature compensation model. The difference value of the preset reference temperature is obtained to obtain the temperature measurement error corresponding to the first distance, and then the difference value between the first temperature value and the temperature measurement error is calculated to obtain the second temperature value. The second temperature value is the difference obtained by subtracting the temperature measurement error from the first temperature value.

Implementation (2): The temperature compensation model includes a temperature compensation function. In the case (i) of the implementation manner (2), the temperature compensation function represents the functional relationship between the temperature measurement distance and the temperature measurement error. For example, the temperature compensation function may be the temperature compensation function 701 shown in FIG. 7A.

In the case (i) of the implementation mode (2), the method for executing S804 on the mobile phone may specifically include: running a temperature compensation model on the mobile phone, and calculating the temperature measurement error corresponding to the first distance collected by the distance sensor of the mobile phone according to the above-mentioned temperature compensation function; Then, the difference between the first temperature value and the temperature measurement error is calculated to obtain a second temperature value. The second temperature value is the difference obtained by subtracting the temperature measurement error from the first temperature value.

For example, take the above-mentioned test object being a person (eg, Bob) as an example. During the j+1 temperature measurement process when the mobile phone is the Bob, as shown in Table 5, it is assumed that the temperature measurement distance measured by the distance sensor is 25mm, and the first temperature value of the Bob measured by the temperature sensor is 36.9°C. Among them, j is a positive integer.

table 5

In this example, the mobile phone executes S804 and runs the temperature compensation model. According to the temperature compensation function shown in Table 2, the temperature measurement error corresponding to the first distance of 25mm can be calculated to obtain -0.2°C, and the first temperature value of 36.9°C and the temperature measurement error can be calculated. A difference of -0.2°C yields a second temperature value of 37.1°C.

In the case (ii) of the implementation manner (2), the temperature compensation function represents the functional relationship between the temperature measurement distance and the measurement temperature value. For example, the temperature compensation function may be the temperature compensation function 702 shown in FIG. 7B.

In the case (ii) of the implementation mode (2), the method for executing S804 on the mobile phone may specifically include: running a temperature compensation model on the mobile phone, and calculating the measured temperature value corresponding to the first distance collected by the distance sensor of the mobile phone according to the above-mentioned temperature compensation function; Then, the difference between the measured temperature value and the preset reference temperature is calculated to obtain the measurement error corresponding to the first distance; finally, the difference between the first temperature value and the temperature measurement error is calculated to obtain the second temperature value. The second temperature value is the difference obtained by subtracting the temperature measurement error from the first temperature value.

Exemplarily, it is assumed that the above-mentioned second temperature value is 37.1°C. After the mobile phone receives the above-mentioned first operation, S804 is executed to display the first interface 1201 shown in FIG. 12 . For example, in response to a user's click operation (eg, a single-click operation) on the "start temperature measurement" control 903 shown in (c) of FIG. 9 or the "start temperature measurement" control 1002 shown in FIG. The first interface 1201 shown in 12. The first interface 1201 may include prompt information 1202, such as "Your temperature is 37.1°C". Alternatively, the first interface may further include prompt information "Your temperature measured by the mobile phone is 37.1°C" or "Your measured temperature is 37.1°C", and the like.

In other embodiments, the above-mentioned first interface may also be used to indicate the above-mentioned first distance. For example, the first interface 1301 shown in FIG. 13 includes not only prompt information 1302 but also prompt information 1303 . The prompt message 1302 is "Your measured temperature is 37.1°C". The prompt message 1303 is "Your temperature measurement distance is 25mm".

Optionally, the above-mentioned first interface may further include a "start temperature measurement" control. For example, the first interface 1201 shown in FIG. 12 may further include a “start temperature measurement” control 1203 . The first interface 1301 shown in FIG. 13 may also include a "start temperature measurement" control 1304. The "start temperature measurement" control 1203 and the "start temperature measurement" control 1304 are used to trigger the mobile phone to measure the temperature of the measured object. The mobile phone may receive the user's click operation (ie, the first operation) on the "start temperature measurement" control 1203 or the "start temperature measurement" control 1304, and then execute the above-mentioned S802-S805.

S805. The mobile phone uses the first distance and the first temperature value to update the temperature compensation model. The updated temperature compensation model is used to perform temperature compensation on the temperature collected by the temperature sensor next time.

In the above implementation manner (1), the above temperature compensation model further includes a preset reference temperature. The mobile phone can update the temperature compensation information of the temperature compensation model by using the above-mentioned first distance and the first temperature value, so as to update the temperature compensation model.

Taking case (1) of implementation (1) as an example, the mobile phone can perform steps (a) and (b), and update the temperature compensation model by using the first distance and the first temperature value.

Step (a): The mobile phone calculates the difference between the first temperature value and the preset reference temperature. Step (b): the mobile phone calculates the product of the difference and the first preset weight to obtain the first value, and calculates the product of the temperature measurement error corresponding to the first distance in the above temperature compensation information and the second preset weight to obtain the second value. ; Then, use the sum of the first value and the second value to update the temperature measurement error corresponding to the first distance in the above temperature compensation information.

The first preset weight and the second preset weight described in the embodiments of the present application are both greater than 0 and less than 1. The sum of the first preset weight and the second preset weight is 1. For example, the first preset weight is 50%, and the second preset weight is 50%. Alternatively, the first preset weight is 40%, and the second preset weight is 60%. Alternatively, the first preset weight is 65%, and the second preset weight is 35%. The first preset weight and the second preset weight may be pre-configured in the mobile phone; or, the first preset weight and the second preset weight may be set by the user in the mobile phone. The embodiments of the present application do not limit the specific values of the first preset weight and the second preset weight.

For example, assuming that the temperature compensation information of the temperature compensation model is the temperature compensation information shown in Table 2, the first preset weight is 50%, and the second preset weight is 50%. During Bob's jth temperature measurement, the mobile phone executes S802-S803, and the first distance is 10mm as shown in Table 4, and the first temperature value is 36.8°C as shown in Table 4. Wherein, the mobile phone performs step (a), and the difference between the first temperature value of 36.8°C and the preset reference temperature of 37.0°C can be calculated by -0.2°C. The mobile phone performs step (b), and can calculate the product of the difference value -0.2°C and the preset weight of 50% to obtain the first value -0.1°C; the first distance of 10mm can be calculated as shown in the temperature compensation information shown in Table 2. The product of the corresponding measurement error -0.1°C and the second preset weight of 50%, the second value -0.05°C is obtained; then, the sum of the first value -0.1°C and the second value -0.05°C can be used -0.15°C, Update the measurement error -0.1°C corresponding to the temperature compensation information shown in Table 2 for the first distance of 10 mm, and obtain the temperature compensation information shown in Table 6.

Table 6

It should be noted that, in the case (2) of the above implementation (1), the mobile phone adopts the principle of updating the temperature compensation model with the above-mentioned first distance and the first temperature value, and in the case (1) of the implementation (1), the mobile phone The principles of updating the temperature compensation model by using the above-mentioned first distance and the first temperature value are similar, and details are not described here in this embodiment of the present application.

The temperature compensation model of the above-mentioned measured object is a preset AI model. Alternatively, the temperature compensation model of the measured object is updated by using the distance collected by the distance sensor and the temperature value collected by the temperature sensor when the temperature of the measured object was measured last time.

It should be noted that, when j=1, the temperature compensation model described in S804 may be a preset AI model preconfigured in the mobile phone. The pre-AI model is configured in the phone when the phone leaves the factory. When j≥2, the temperature compensation model described in S804 may be: during the j-1 th temperature measurement process of Bob, the mobile phone adopts the first distance and the first temperature value collected during the j-1 th temperature measurement process , the updated AI model (that is, the updated temperature compensation model). The temperature compensation model updated by the mobile phone in Bob's jth temperature measurement process can be used to perform temperature compensation on the first temperature collected in Bob's j+1th temperature measurement process.

In the above implementation mode (2), the mobile phone can use the above-mentioned first distance and the first temperature value to update the temperature compensation function of the temperature compensation model, so as to realize the update of the temperature compensation model.

Taking case (i) of implementation (2) as an example, the mobile phone can perform steps (A) and (B), and update the temperature compensation model by using the first distance and the first temperature value.

Step (A): The mobile phone calculates the difference between the first temperature value and the preset reference temperature. Step (B): the mobile phone calculates the difference, calculates the product of the difference and the first preset weight to obtain the first value, and calculates the product of the temperature measurement error corresponding to the first distance in the above-mentioned temperature compensation function and the second preset weight Obtain a second value; then, use the sum of the first value and the second value to update the temperature measurement error corresponding to the first distance in the above temperature compensation function.

Take case (i) of implementation (2) as an example. Assuming that the temperature compensation function of the temperature compensation model is the temperature compensation function 701 shown in FIG. 7A , the first preset weight is 30%, and the second preset weight is 70%. During Bob's j+1 temperature measurement, the mobile phone executes S802-S803, the first distance is 25mm as shown in Table 5, the first temperature value is 36.9°C as shown in Table 5, and the preset reference dimension is 37.0°C . Wherein, the mobile phone performs step (A), and the difference between the first temperature value of 36.9°C and the preset reference temperature of 37.0°C can be calculated by -0.1°C. The mobile phone performs step (B), and can calculate the difference, calculate the product of the difference -0.1°C and the first preset weight of 30% to obtain the first value -0.03°C, and calculate the temperature compensation function 701 corresponding to the first distance of 25mm. The product of the temperature measurement error of -0.2°C and the second preset weight of 70% gets the second value -0.14°C; then, using the sum of the first value -0.03°C and the second value -0.14°C -0.17°C, update the above In the temperature compensation function 701, the temperature measurement error corresponding to the first distance of 25 mm is -0.2°C, and the temperature compensation function 1101 shown in FIG. 11A can be obtained.

In the embodiment of the present application, after each time the mobile phone measures the temperature of the measured object, the current measurement result (including the temperature measurement distance and the measured temperature value) can be used to update the temperature compensation model of the measured object. In this way, self-adaptive learning of the temperature compensation model can be realized, and the accuracy of temperature compensation performed by the temperature compensation model can be improved. Wherein, when the temperature of the measured object is measured next time, the temperature compensation model after this update can be used to perform temperature compensation on the measured temperature value collected by the temperature sensor. In this way, the accuracy of the temperature measurement result can be improved.

It can be understood that the measured temperature value (eg, the first temperature value) collected by the above temperature sensor is the temperature of the measured object collected by the temperature sensor. Although the measured temperature value collected by the temperature sensor may be different from the actual temperature of the measured object due to the influence of the temperature measurement distance (such as the first distance); The measured temperature value can still reflect the temperature characteristics of the measured object. Different measured objects have different temperature characteristics (such as real temperature values). Therefore, after each time the mobile phone measures the temperature of the measured object, the temperature compensation model of the measured object is updated with the current measurement result, and a temperature compensation model conforming to the temperature characteristics of the measured object can be obtained. In this way, the degree of fit between the temperature compensation model and the temperature characteristics of the measured object can be improved, which is beneficial to further improve the accuracy of the temperature measurement of different measured objects by the mobile phone.

Exemplarily, in the embodiment of the present application, the mobile phone measures the temperature of two users (eg, user a and user b) for multiple times, and updates the temperature compensation model of user a and the temperature compensation model of user b as an example. By comparing the temperature compensation model of user a (such as a temperature compensation function) and the temperature compensation model of user b (such as a temperature compensation function) after multiple temperature measurements, the effects achieved by the embodiments of the present application are described.

Assuming that when the mobile phone leaves the factory, the temperature compensation model preconfigured in the mobile phone for measuring the temperature of the human body includes the temperature compensation function 701 shown in FIG. 7 . The mobile phone executes S801-S805, and after measuring the temperature of user a for P times, the temperature compensation function 701 shown in FIG. 7 is updated to the temperature compensation function 1102 shown in FIG. 11B . After the mobile phone executes S801-S805 and measures the temperature of user b for P times, the temperature compensation function 701 shown in FIG. 7 is updated to the temperature compensation function 1103 shown in FIG. 11B . Wherein, P is a positive integer greater than 8.

After the mobile phone executes S801-S805 and measures the temperature of user a for Q times, the temperature compensation function 1102 shown in FIG. 11B is updated to the temperature compensation function 1104 shown in FIG. 11B . After the mobile phone executes S801-S805 and measures the temperature of user b for Q times, the temperature compensation function 1103 shown in FIG. 11B is updated to the temperature compensation function 1105 shown in FIG. 11B . Among them, Q>P+8, Q is a positive integer.

It can be understood that different users a have different temperature characteristics (such as real temperature values); therefore, the mobile phone performs the method of the embodiments of the present application to measure the temperature of different users multiple times, and the temperature compensation models updated for each user are different. Therefore, after each measurement of the temperature of a measured object, the temperature compensation model of the measured object is updated according to the current measured temperature value and temperature measurement distance, which can improve the fit of the temperature compensation model and the temperature characteristics of the measured object. , which is conducive to further improving the accuracy of the temperature measurement of different measured objects by the mobile phone.

In some embodiments, in response to the above-mentioned first operation, after the mobile phone collects the first temperature value of the measured object through the temperature sensor (ie, S802), the mobile phone may not perform S803-S805; Within the preset distance range [M1, M2]. If the above-mentioned first distance is within the preset range, the mobile phone may execute S803-S805.

Wherein, the above-mentioned preset distance range [M1, M2] may be the value range of the temperature measurement distance in the plurality of training samples used for training or creating the temperature compensation model of the measured object in the above-mentioned stage (1). Alternatively, the above-mentioned preset distance range [M1, M2] may be a distance range preconfigured in the mobile phone. Alternatively, the above-mentioned preset distance ranges [M1, M2] can also be set by the user in the mobile phone.

For example, the above-mentioned preset distance range [M1, M2] may be 5 mm˜100 mm. Alternatively, the preset distance range can be [M1, M2] 5mm～50mm. Alternatively, the preset distance range may be [M1, M2] 6 mm to 60 mm. It should be noted that, in this embodiment of the present application, for different types of measured objects, the preset distance range may have different values. Moreover, in different electronic devices, the value of the preset distance range may also be different. The specific value of the preset distance range is not limited in this embodiment of the present application. In the following embodiments, the methods of the embodiments of the present application are described by taking the preset distance range [M1, M2] as an example of 5 mm˜100 mm.

Specifically, if the above-mentioned first distance is within the preset distance range [M1, M2], the mobile phone may execute S803-S805. If the above-mentioned first distance is not within the preset distance range [M1, M2], the mobile phone can measure the first distance through the distance sensor again. That is, the mobile phone can re-execute S802.

In some embodiments, if the above-mentioned first distance is within the preset distance range [M1, M2], the mobile phone may execute S803-S804, and the displayed first interface may further include third prompt information. The third prompt information is used to indicate that the first distance is within the preset distance range [M1, M2], or may indicate that the size of the first distance is moderate. For example, the first interface 1301 shown in FIG. 13 may further include third prompt information 1305, such as "The distance is moderate!".

In some embodiments, if the above-mentioned first distance is not within the preset range [M1, M2], the mobile phone may display guidance information. The guidance information is used to indicate that the above-mentioned first distance is not within the preset range [M1, M2]. For example, the mobile phone can display the prompt information 1402 shown in (a) of FIG. 14 , such as "The distance between the mobile phone and the measured object is not within 5mm to 100mm!".

It can be understood that the following two situations may exist when the temperature measurement distance collected by the distance sensor is not within the preset distance range. Situation (a): The temperature measurement distance collected by the distance sensor is smaller than the first boundary value M1 of the preset distance range [M1, M2] (ie, the above-mentioned distance threshold 1). Situation (b): The temperature measurement distance collected by the distance sensor is greater than the second boundary value M2 of the preset distance range [M1, M2] (ie, the above-mentioned distance threshold 2). The first boundary value M1 is the minimum value of the preset distance range, and the second boundary value M2 is the maximum value of the preset distance range. The second boundary value M2 is greater than the first boundary value M1.

In the above cases (a) and (b), the mobile phone can send out different guidance information. For example, in the above case (a), that is, in the case where the first distance is smaller than the first boundary value M1 of the preset distance range [M1, M2], the mobile phone can display the first guidance information shown in (c) in FIG. 14 . 1402, such as "The distance between the mobile phone and the measured object is too close, please keep the distance within 5mm~100mm!". For another example, in the above-mentioned situation (b), that is, the first distance is greater than the second boundary value M2 of the preset distance range [M1, M2], the mobile phone can display the second guide shown in (b) of FIG. 14 . Information 1404, such as "The distance between the mobile phone and the measured object is too far, please keep the distance within 5mm~100mm!".

It should be noted that, if the above-mentioned first distance is not within the preset distance range [M1, M2], the mobile phone can perform S802 to re-collect the first distance. If the re-collected first distance is within the preset distance range [M1, M2], the mobile phone can automatically execute S803-S805.

It can be understood that, compared with the first temperature value collected by the mobile phone when the first distance is not within the preset distance range [M1, M2], the temperature compensation model is run, and the first distance is within the preset distance range [M1, M2]. When performing temperature compensation on the first temperature value collected by the mobile phone, the obtained second temperature value is closer to the real temperature value of the measured object. Therefore, in the embodiment of the present application, the mobile phone measures the temperature of the measured object when the first distance is within the preset distance range [M1, M2], which can improve the accuracy of the temperature measurement result.

Take the user Bob as an example. When Bob has a fever, the first temperature value of Bob measured by the mobile phone may be higher than the normal temperature value of the human body. For example, the first temperature value of Bob measured by the mobile phone may be 38°C or 39°C, or even 40°C. Among them, when Bob has a fever, the first temperature value measured by the mobile phone belongs to the abnormal temperature value of the user. Or, when Bob's body temperature is too low (lower than the normal temperature value of the human body) due to illness, the first temperature value measured by the mobile phone belongs to the abnormal temperature value of the user. Wherein, using the abnormal temperature value and the first distance to update the above-mentioned temperature compensation model may affect the accuracy of temperature measurement performed by the updated temperature compensation model under the condition that Bob's body temperature is normal.

For example, taking the case (1) of implementation (1) as an example, the abnormal temperature value and the first distance are used to update the above-mentioned temperature compensation model. The absolute value of the temperature measurement error corresponding to a distance will increase significantly. In this way, even if Bob's body temperature is normal; the mobile phone runs the updated temperature compensation model, and when the temperature measurement distance is the above-mentioned first distance, measuring Bob's temperature, the obtained first temperature value and second temperature value may also be The abnormal temperature value, that is, the first temperature value and the second temperature value are quite different from the normal temperature value of the human body.

Based on this, before executing S805 to update the temperature compensation model, the mobile phone can determine whether the above-mentioned first temperature value is within the preset temperature range. If the first temperature value is within the preset temperature range, the mobile phone may execute S805. If the first temperature value is not within the preset temperature range, the mobile phone may not execute S805. It should be noted that, regardless of whether the first temperature value is within the preset temperature range, the mobile phone performs S804. That is to say, even if the mobile phone detects that the temperature of the measured object is abnormal, the mobile phone can display the second temperature value obtained by performing temperature compensation on the first temperature value. However, the phone will not update the temperature compensation model with this first temperature value.

Exemplarily, the above-mentioned preset temperature range may be a value range of the normal temperature of the human body. For example, the preset temperature range may be 36.3°C˜37.2°C. The preset temperature range may be a pre-configured temperature range in the mobile phone. Alternatively, the above-mentioned preset temperature range may also be set by the user in the mobile phone. It should be noted that, in the embodiment of the present application, for different types of measured objects, the values of the preset temperature range may be different. The embodiment of the present application does not limit the specific value of the preset temperature range.

In the embodiment of the present application, the mobile phone uses the first temperature value within the preset temperature range to update the temperature compensation model. Instead of adopting a first temperature value outside the preset temperature range (ie, an abnormal first temperature value), the temperature compensation model is updated. In this way, the accuracy of temperature compensation performed by the temperature compensation model can be guaranteed.

In other embodiments, multiple temperature compensation models may be stored in the mobile phone. Therefore, before the above S804, the mobile phone can select a temperature compensation model for the measured object from the plurality of temperature compensation models for temperature compensation.

In an implementation manner, in response to the above-mentioned first operation, the mobile phone can activate the camera, and collect the image of the measured object through the camera. Then, the mobile phone can identify the measured object according to the image of the measured object, and select a temperature compensation model for the measured object from the plurality of temperature compensation models.

For example, suppose that the temperature compensation model a of the human body and the temperature compensation model b of the cat are pre-configured in the mobile phone. In the process of measuring the temperature for Bob for the first time by the mobile phone, in response to the above-mentioned first operation, the image of Bob can be collected through the camera. The mobile phone can recognize that the type of Bob is human. Then, the mobile phone can select the temperature compensation model a to execute S804. In the process of measuring the temperature of a kitten for the first time by the mobile phone, in response to the above-mentioned first operation, an image of the kitten can be collected through the camera. The mobile phone can identify the type of the tested object as a cat. Then, the mobile phone can select the temperature compensation model b to execute S804.

Further, the mobile phone can also acquire object features of the measured object (such as a human face image, a cat face image, or iris information, etc.). The object feature may be extracted from an image captured by a camera; or, the object feature is an image captured by a camera. Wherein, after the mobile phone executes S805, an updated temperature compensation model of the measured object can be obtained, such as the updated temperature compensation model a or the updated temperature compensation model b. The mobile phone can save the above-mentioned object feature and the updated temperature compensation model of the measured object corresponding to the object feature. For example, the mobile phone can store Bob's biometric feature a, and Bob's updated temperature compensation model a-1 corresponding to the biometric feature a.

Exemplarily, in the above-mentioned case of j=1, after the mobile phone executes S805, the temperature compensation model shown in Table 7 can be saved.

Table 7

In another implementation manner, the user may select one temperature compensation model for the measured object from the above-mentioned multiple temperature compensation models. For example, in response to the above-mentioned first operation, the mobile phone may display a third interface. The third interface includes a plurality of model options, and each model option corresponds to a temperature compensation model among the above-mentioned plurality of temperature compensation models.

Exemplarily, in response to the above-mentioned first operation, the mobile phone may display the third interface 1501 shown in FIG. 15 or the third interface 1701 shown in FIG. 17 . For example, after the mobile phone leaves the factory, in response to the above-mentioned first operation, the third interface 1501 shown in FIG. 15 can be displayed when the temperature is measured for the first time. The third interface 1501 includes model options for various types of measured objects, such as model options 1502 for "human body", model options 1503 for "cat", and model options 1504 for "dog".

In some embodiments, in response to the user's selection operation on the first model option in the third interface, the mobile phone may perform the above S802-S805. The temperature compensation model described in S804 and S805 is the temperature compensation model corresponding to the first model option. For example, in response to the user's selection operation on the "human body" model option 1502 in the third interface 1501 shown in FIG. 15 , the temperature compensation model described in S804 and S805 above is the temperature compensation corresponding to the "human body" model option 1502 model, such as the temperature compensation model a shown in Table 1 or Table 7.

In other embodiments, in response to the user's selection operation of the first model option in the third interface, the mobile phone may further display a fourth interface, where the fourth interface is used to request the user to set an identification for the measured object. Receive the identifier of the measured object input by the user on the fourth interface, and in response to the user's second operation on the fourth interface, perform the above S802-S805, and save the updated temperature according to the identifier of the measured object Compensation model.

Exemplarily, in response to the user's selection operation on the model option 1502 of "human body" in the third interface 1501 shown in FIG. 15 , the mobile phone may display the fourth interface 1601 shown in FIG. 16 . The fourth interface 1601 includes an identification input box 1602 . The fourth interface 1601 further includes a "OK, and temperature measurement" button and a "Cancel" button. The above-mentioned second operation is used to trigger the mobile phone to use the temperature compensation model corresponding to the above-mentioned first model option to perform temperature compensation on the first temperature. For example, the second operation may be a click operation (such as a click operation) of the "OK, and measure temperature" button by the user. Alternatively, the second operation may also be a preset gesture input by the user on the fourth interface, such as an S-shaped gesture or an L-shaped gesture. Alternatively, the second operation may also be that when the mobile phone displays the above-mentioned fourth interface, a voice command input by the user, such as "start temperature measurement", is received.

The mobile phone can receive the identification "Bob" input by the user in the identification input box 1602, and in response to the user's click operation on the "OK, and measure temperature" button, the above-mentioned S802-S805 can be executed, and according to the identification (Bob) of the measured object. ) to save the updated temperature compensation model. For example, after the mobile phone executes S805, the temperature compensation model stored in the mobile phone is updated from the temperature compensation model shown in Table 1 to the temperature compensation model shown in Table 7. Thereafter, when the mobile phone receives the above-mentioned first operation next time, in response to the first operation, the third interface 1701 shown in FIG. 17 can be displayed. The third interface 1701 includes the model options 1702 of the temperature compensation model a-1 shown in Table 7.

In this embodiment of the present application, the mobile phone may select a temperature compensation model for the measured object according to the biological characteristics of the measured object; or, the user may manually select a temperature compensation model for the measured object. In this way, suitable temperature compensation models can be selected for different measured objects to perform temperature compensation, which can improve the accuracy of temperature measurement results.
