Description

TECHNICAL FIELD [0001] The present invention relates to a body temperature sensing system using a thermal imaging camera,

The present invention relates to a system for detecting body temperature in real time using a thermal imaging camera.

More particularly, the present invention relates to a body temperature sensing system using a thermal imaging camera that is installed in a patient's room and an intensive care unit room to photograph a patient and detect the body temperature of the patient with respect to a specific region in the captured image.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body temperature sensing system using a thermal imaging camera capable of detecting a patient body temperature in real time and displaying the corrected body temperature by correcting the actual body temperature.

Body temperature refers to the temperature inside the body. Body temperature varies greatly depending on the area of the body, but the temperature of the rectum measured at the area of 6 cm or more from the anus is the standard body temperature. Normal human body temperature is 36.9 ° C at the armpit temperature, and children are slightly higher than adults and tend to be lower in the elderly.

The high temperature condition of the body temperature causes more severe conditions than the low temperature condition.

Body temperature is about 37 ℃ for adults, normal body temperature, about 41 ℃ for seizures and pain causes, 43.3 ℃ is the maximum limit of life maintenance. In addition, life can not be maintained even at body temperature of 27 ℃ or less.

These body temperatures react according to the disease. Patients admitted to the hospital live in the room and receive periodic tests. The items to be checked periodically include blood pressure, pulse rate and body temperature. Of these, blood pressure and pulse can be checked in real time by attaching the measuring device to the patient's body.

However, there is no suitable device for real - time examination of the body temperature, and the patient 's body temperature is measured by the nurse at regular intervals using a clinical thermometer. Therefore, a lot of manpower is required to inspect the body temperature.

In addition, the body temperature test is performed not only in the daytime but also in the nighttime in case of the hospitalized patient, and there is a problem that the patient can be awakened at the nighttime examination.

In order to solve the above problems, various devices for monitoring the body temperature and the patient condition using a thermal imaging camera have been proposed.

As one of various devices for monitoring patient status, a patient condition monitoring system is described in Patent No. 10-1070389.

The above-described technique includes an image sensing unit for capturing a thermal image for detecting a patient's biometric information by tracking a movement of the patient; A sensor unit for sensing a pressure and a motion applied to the bed by the movement of the patient; A computer for controlling the image sensing unit and the sensor unit, collecting the biometric information of the patient from the thermal image, collecting the movement of the patient through the pressure information and the motion information, and monitoring the condition of the patient; . At this time, the face region of the patient is tracked from the thermal image transmitted from the thermal imaging camera, and the body temperature of the patient is measured through the temperature difference of the face region.

In addition, a newborn baby monitoring system using a thermal imaging camera is disclosed in Korean Patent Registration No. 10-1242755.

The above technique measures the respiration of a newborn by setting a ROI (Region Of Interest) on the face of a newborn by a thermal camera and measures the temperature of the newborn through thermal body extraction. Information can be checked, and the measurement result can be remotely monitored from the server.

However, the body temperature of a person is different according to time, age, and site. The system for measuring the body temperature of a patient using the conventional thermal imaging camera does not reflect this.

In other words, the normal body temperature is recognized as 37 ° C, but it varies from day (35.6 ° C) to night (37 ° C).

It is also known that the body temperature of the oral cavity during the early morning and morning hours may drop to 36.4 ° C, while it increases to 37.7 ° C during the afternoon of 4 ~ 6 pm.

The human body has deep body temperature and surface body temperature. The deep body temperature is the body temperature distributed around the reference point when the person is cut from head to crotch, and the surface body temperature literally refers to the temperature of the body surface of a person.

The body temperature of each part of the human body is 34.7 ~ 37.3 ℃ in the armpit, 35.5 ~ 37.5 ℃ in the oral cavity, 36.6 ~ 38.0 ℃ in the anus and 35.8 ~ 38 ℃ in the eardrum.

Therefore, the body temperature varies depending on the measurement site, so it should be able to reflect this.

In addition, body temperature varies according to age, ranging from 0 to 2 years of age 36.4 to 38 ° C, from 3 to 10 years of age 36.1 to 37.8 ° C, from 11 to 65 years of age 35.9 to 37.6 ° C, and from 65 to over 35.8 to 37.5 ° C, It must be able to reflect this according to age.

FIG. 3 is a plan view showing an embodiment in which a body temperature sensing system using a thermal imaging camera according to the present invention is applied to a patient room.

The body temperature sensing system using the thermal imaging camera according to the present invention includes a thermal imaging unit 100, a control computer 200, and a mobile device 300.

The thermal imaging unit 100 is a device for shooting a thermal image of a person to be imaged, and captures a person to be imaged in the imaging range. Here, the subject to be photographed may be a patient admitted to a hospital.

Further, the thermal imaging unit 100 adjusts the imaging direction in accordance with the control signal. That is, the photographing direction is adjusted so as to photograph the object to be photographed, and the object is photographed at the adjusted position.

To this end, the thermal imaging unit 100 includes a thermal imaging camera 110, a photographing direction control unit 120, and a temperature detection unit 130.

The thermal imaging camera 110 can not only generate an image by temperature difference with a camera that measures thermal (temperature) distribution, but also can accurately measure this temperature difference. In addition, since all objects with an absolute temperature of 0K or higher generate infrared rays themselves, there is an advantage that images can be obtained irrespective of day or night without using any additional illumination using a thermal imaging camera.

Although the thermal imaging camera 110 has been developed for military purposes for the purpose of night surveillance, nowadays, the use of the non-contact type temperature measurement equipment has been recognized and application examples are increasing.

The thermal imaging camera 110 can acquire images without any illumination and can accurately measure the temperature difference, and thus, it is possible to perform various functions such as a transportation means such as an automobile or a railroad, a surveillance system, defect inspection of electronic equipment, It can be applied to various fields.

In the present invention, it is used to photograph a thermal image of a person to be photographed (patient).

The area in which the thermal imaging camera 110 is installed is installed in a room where the patient's body temperature needs to be measured periodically, in the intensive care unit, and in the area where the patient is located at the designated location. In this case, when a plurality of subjects are to be photographed, they may be installed on a ceiling or a wall surface capable of photographing a plurality of patients optimally, and may be installed on separate supports according to the environment of the installation area.

The photographing direction control unit 120 adjusts the photographing direction of the thermal imaging camera 110 according to an input control signal. Accordingly, the photographing direction controller 120 includes a panning module, a tilting module, and a magnification adjusting module to adjust the angle of the left and right angles, the vertical angle, and the zoom magnification of the thermal imaging camera 110.

Paning means moving the camera horizontally to the left and right, and tilting means moving the camera up and down. Also, the magnification means zooming in / out to enlarge / reduce the shooting area. The photographing direction control unit 120 is realized by hardware and / or software control of a driving motor (pan drive motor and tilt drive motor) for moving the camera vertically and horizontally, and a lens driving motor for controlling the focal distance by moving the lens.

The temperature detecting unit 130 detects the ambient temperature of the area where the thermal imaging camera 110 is installed. The detected temperature can be used as data for correcting the body temperature of the person to be photographed.

According to the design conditions, the temperature detector 130 may be configured as a separate temperature sensor to detect the ambient temperature of the object to be photographed.

Further, the temperature detector 130 may be configured not to be included in the thermal imaging unit 100 but as a separate device installed around the subject.

The control computer 200 calculates the body temperature of the photographed subject based on the thermal image transmitted from the thermal imaging unit 100. [ And transmits the body temperature result calculated according to the body temperature of the object to be photographed to the portable terminal.

And also outputs a control signal for determining the photographing direction to the thermal imager 100. [

The body temperature of the subject to be photographed is calculated based on the detected body temperature based on the body information and environmental information of the subject to be photographed.

To this end, the control computer 200 includes a body temperature calculation unit 210, a body temperature determination unit 220, a text sending unit 230, and a photographing direction setting unit 210.

The body temperature calculation unit 210 detects the body temperature of the subject to be photographed in the thermal image captured by the thermal imaging camera 110 and calculates the corrected body temperature based on the detected body temperature and environmental information of the subject do.

First, in order to detect the body temperature of the subject to be photographed in the thermal image photographed by the thermal imaging camera 110, it is necessary to limit the specific region of the subject to be photographed from the photographed thermal image.

For example, in the case of an inpatient or an intensive care unit, the bed is often heated in a lying state, so that the area exposed by the thermal imaging camera may be the upper half of the subject and may be limited to the face area have.

At this time, when the subject to be photographed covers the blanket, the thermal image of the chest part can be detected similar to the ambient temperature. Therefore, the upper part of the subject to be photographed may be defined as a face, and a face recognition module capable of recognizing the face is included.

The face recognition module can be applied to the body posture recognition based user posture recognition algorithm by analyzing the local heat source distribution of the thermal image captured by the thermal imaging camera 110. The face part is extracted from the photographed thermal image. More preferably, it may be limited to the nose and mouth portions of the subject to be photographed.

In other words, the face region may be regarded as a body temperature sensing region in a progressive image processed in real time in an ISP (Image Signal Processor), which is generally included in the thermal imaging camera 110, so as to be automatically focused. At this time, various algorithms such as the AdaBoost algorithm can be applied to the setting of the detection area, that is, the face area.

The body temperature detecting module detects the body temperature of the subject to be photographed according to the color in the photographed thermal image. That is, the body temperature detecting module detects the body temperature of the object to be photographed in the region of the set thermal image.

Preferably, it can be set as a face part through the face recognition module, and more preferably, it can be limited to the nose and mouth periphery of the object to be photographed of the face area.

Or the thermal image points around the nose and mouth according to the design conditions to detect the body temperature and to set the body temperature of each of the divided partial body temperatures to the body temperature of the object to be photographed.

In the case of cold disease, nasal congestion may occur. Therefore, when the sensing part of the body temperature is limited to the nose and the mouth, the body temperature of the nose portion may be detected to be lower than the body temperature of the subject due to the nasal congestion symptom. Therefore, the body temperature of the portion detected at the height in the nose and mouth can be configured to be sensed by the body temperature of the subject to be photographed.

The human body temperature has been described in the Background of the Invention that the body temperature may be different for each measurement site.

In addition, if the body temperature is measured in the oral cavity, it is detected with a certain error at 37 ° C in the normal case, but the inside of the armpit or rectum is 0.6 ° C higher than the oral cavity and is not affected by the outside temperature.

However, when the detection region is set as the face, the face region is detected to be 1 ~ 2 ° C lower than the body centroid temperature as it is exposed to the air. Also, body temperature is related to age, so young children are about 1 ° C higher than adults.

The body temperature changes several times a day, but it is somewhat low at about 6 to 7 am and high at about 18 to 19 pm (about 1 ° C).

Therefore, the body temperature of the subject to be photographed detected in the thermal image photographed by the thermal imaging camera 110 must be corrected based on the body information (age) of the subject and environmental information (photographing time and ambient temperature).

If the body temperature detected from the pure thermal image not corrected according to the body information and the environmental information reflects the age, the temperature detection time and the ambient temperature of the person to be photographed, it is troublesome for the person in charge (doctor, nurse, etc.) have.

In addition, when the system is configured to automatically generate an alarm, there is a problem that a normal body temperature range in consideration of body information and environmental information must be set for each person to be photographed.

In other words, the range of setting the normal body temperature of the child and the adult must be input in different ranges to cope with the change in body temperature of the subject.

For example, when the age of the subject is 0 to 2 years, the normal body temperature should be set at 36.4 to 38 ° C. If the age of the subject is 11 to 65 years, the normal body temperature range is 35.9 to 37.6 ° C Emergency coping is possible for body temperature conversion.

Therefore, the body temperature correction module of the present invention is for correcting the sensed body temperature according to the ambient temperature of the subject to be photographed.

The body temperature correction module is for correcting the body temperature detected in the face region of the photographed thermal image on the basis of the body information and the environment information of the subject to be photographed. The body temperature correction module corrects the temperature by the exposure of the body surface, And the ambient temperature (the temperature of the photographing area).

Therefore, there is an advantage that the body temperature of the subject to be photographed can be collectively leveled.

Therefore, when only the age of the subject (patient) is input, the range of the normalized normal body temperature is specified, and the range of the normal body temperature can be fixed regardless of the age, shooting time zone, and ambient temperature of the subject.

At this time, the more specific correction value is set to a temperature of 1 to 2 ° C due to exposure of the surface of the body, a temperature of ± 1 to 2 ° C according to age, a temperature of ± 1 ° C due to time of shooting and a temperature of 0.5 to 2 ° C .

On the other hand, body temperature changes are controlled by autonomic nerves to minimize the influence of outside temperature. So in normal cases sudden changes in body temperature are rare.

If a person enters a hot spot, the skin temperature rises at first, and when the subject is photographed, the temperature of the subject may be sensed higher than the subject's body temperature.

On the other hand, if the subject is in a cold place, the body temperature of the person to be photographed may be lowered. When a certain period of time elapses, the body temperature is normally controlled by the amount of pore enlargement and sweat discharge.

However, such changes in body temperature may vary depending on the disease. That is, the body temperature that is regulated after a certain period of time according to the ambient temperature corresponds to a normal person.

In the case of a patient suffering from a disease, if there is a problem with the bio-autonomic nerves that can control it, it may not be converted to a normal body temperature even after a certain period of time has elapsed.

Accordingly, the present invention is configured to correct the sensed body temperature according to the sensed ambient temperature from the temperature detection unit 130. FIG.

At this time, the correction value for the ambient temperature can be calculated by the following equation.

[Mathematical Expression]

Here, Tc (corrected body temperature) is the corrected body temperature, Td (detecting body temperature) is the body temperature detected in the image of the thermal imaging camera, Ts (standard temperature) is the reference temperature and Ta Temperature.

In the above equation, the reference temperature is different not only depending on the quality of the work, the age, sex, dress, season, environment, individual difference, etc. when the person is in a stable state or work, The air humidity, the air flow, the surrounding heat radiation state, and the like. However, the optimum room temperature in a safe state is 18 ° C when the humidity is about 60%. However, since the patient may feel chills at 18 캜, it can be selected within the range of 18 to 25 캜 or in the range of 20 to 23 캜.

For example, when the reference temperature is selected to be 20 占 폚, when the detection temperature (Ta) is 1 占 폚 higher than the reference temperature, the correction value of the body temperature is 占 05.

The detected body temperature is corrected according to the ambient temperature, so that the body temperature of the object to be photographed can be detected more accurately.

The body temperature determination unit 220 determines whether or not it is normal according to the body temperature of the sensed subject. Normal body temperature is 36 ~ 37 ℃ for adults. At this point, it can be said that there is heat above 37 ℃. However, infants have normal body temperature up to 37.5 ℃.

The body temperature of daytime (day) and night (night) is about 35.6 ℃ and 37 ℃ respectively for adults. The body temperature is slightly elevated at night, so I feel chills at dawn.

Since the body temperature corrected by the body temperature correction module of the present invention is calibrated according to the age and the photographing time period, the range of the normal body temperature can be set and unified, so that it is determined that the calculated body temperature value is within the normal range .

When the body temperature determined by the body temperature determination unit 220 is out of the normal range, it can be configured to be output through the notification module.

Here, the notification module is configured to be displayed on the monitor through the interface or to generate an alarm sound or the like.

The character sending unit 230 is for informing the relevant portable terminal 300 of the body temperature of the subject to be photographed, which is determined by the body temperature determination unit 230, from the normal temperature.

At this time, the notification sent from the character sending unit 230 may be composed of a short message.

The photographing direction setting unit 240 changes the photographing direction angle and the magnification (zoom) of the thermal imaging camera 110 according to the position of the photographing target person when the photographing target person (patient) is plural, Respectively.

At this time, the allowable range of the body temperature and the weight can be set according to the illness of the person to be photographed.

To this end, the photographing direction setting unit 240 includes a photographing direction setting module, a patient information setting module, and a weight setting module.

FIG. 4 shows a data table of an embodiment that is input to the photographing direction setting unit 240 in the body temperature sensing system using the thermal imaging camera according to the present invention.

According to the attached drawings, the photographing direction setting unit 240 is configured to set the photographing direction setting unit 240 to a panning angle, a tilting angle for setting the vertical angle, a magnification for setting the magnification, a disease, an allowable range and a weight And the like.

The data table shown in FIG. 4 is based on a four-person room, and a data table is displayed corresponding to the size of the room to accommodate the patient and the patient to be accommodated.

A data table can also be configured based on a single-person room.

It should be understood that the data table can be configured to manually adjust the direction and magnification by manually operating the camera, and to input the adjusted direction and magnification into the data table according to the design conditions.

The photographing direction setting module inputs and sets the panning angle, tilting angle and magnification. The panning angle, the tilting angle, and the magnification are set to an optimum angle at which the face (face) of the imaging subject can be photographed according to the position of the imaging subject. At this time, the angle to be set is configured such that the user changes the photographing direction of the thermal imaging camera 110 by using a joystick or the like based on the bed (bed) on which the person to be photographed lies and manipulates the button at the variable position . That is, the user may be configured to forcibly adjust the photographing direction control unit 120 while viewing an image displayed through the thermal imager 110, and to set the adjusted angle to panning, tilting, and magnification.

The patient information setting module inputs and sets the information of the person to be photographed (patient) and the disease, and is configured to be able to input the name, age, sex, and disease of the patient.

In addition, the patient information setting module is configured so that the allowable range can be inputted and set. Here, the allowable range means a range in which the body temperature of the subject to be photographed can be tolerated depending on the disease.

For example, certain diseases may be sensitive to changes in body temperature, and diseases such as simple fractures or abrasions may be configured not to respond sensitively to body temperature changes.

More specifically, it is necessary to respond sensitively to changes in body temperature such as H1N1, meningitis, Japanese encephalitis, heat stroke, malaria, yellow fever, dengue fever, epidemic hemorrhagic fever, Tsutsugamushi, leptospirosis and sepsis. .

Conversely, diseases such as fractures and bruises may not be responded quickly to changes in body temperature, so that the allowable range may be set to a high value.

For example, the permissible range of H1N1, meningitis, and Japanese encephalitis can be set to be ± 1, and diseases such as fracture can be set to ± 2. In other words, for diseases such as swine flu, meningitis and Japanese encephalitis, when a body temperature change of ± 1 ° C or more occurs in the body temperature of the first stored body temperature, a warning alarm is generated. In the case of a disease such as a fracture, .

The weight setting module is configured to input and set the time taken by the thermal imaging camera 110 in accordance with the illness of the imaging subject, that is, the time for imaging the imaging subject.

For example, a patient with a disease setting a low tolerance of the above-mentioned tolerance range can respond more quickly to body temperature changes if he or she detects the temperature more intensively.

In one embodiment, it may be set between 5 and 10 minutes for a specific disease and between 1 and 5 minutes for other diseases.

When the imaging direction of the thermal imaging camera 110 is adjusted so that the disease of the imaging subject is a specific disease, the imaging is performed for a time corresponding to the weight, and when the time corresponding to the weight is exceeded, And the body temperature of the photographed subject is calculated and stored and managed.

Therefore, by applying a weight according to a specific disease, a patient suffering from a specific disease can be intensively photographed, and when a temperature change occurs, the patient can cope with it rapidly.

The portable terminal 300 is a terminal carried by a nurse, a doctor in charge and a guardian related to the person to be photographed.

Accordingly, when the body temperature of the subject to be photographed deviates from the normal body temperature, a notification message is received from the control computer 200 so that the subject can be promptly dealt with.

5 and 6 are a plan view and a side view, respectively, of an embodiment in which a body temperature sensing system using a thermal imaging camera according to the present invention is applied to a patient room.

At this time, the thermal imager 100 sequentially captures the object to be imaged based on the data table set in the imaging direction setting unit 210, and transmits the imaged thermal image to the control computer 200.

The photographing time is photographed by the set weighting time based on the set weighting, and when the set weighting time elapses, the photographing direction is adjusted so as to photograph the next photographing target person in accordance with the control signal.

The control computer 200 (see FIG. 2) senses the body temperature of the object to be imaged through the thermal image transmitted from the thermal imaging unit 100. The sensed body temperature corrects the body temperature according to the ambient temperature, and determines whether the body temperature of the object to be photographed is normal.

At this time, the judgment as to whether the sensed body temperature is normal is judged comprehensively based on the information (gender, age) of the person to be photographed, the disease, the photographing time, the error value and the permissible range.

When the determined body temperature is out of the normal range, it is displayed on the interface of the control computer 200 or a text message is transmitted to the participant portable terminal 300.

According to the present invention, it is possible to detect the body temperature that minimizes the actual body temperature and the error range with the thermal imaging camera, so that when the present invention is applied to the patient who enters the room, the body temperature of the patient can be accurately detected, There is an effect to be able to create the conditions. Further, since the corrected body temperature can be detected according to the age and the measurement time of the patient, the range of the normal body temperature can be specified, and the present invention can be applied to various subjects to be photographed under the same normal body temperature range.

1 to 6 are merely the main points of the present invention. As various designs can be made within the technical scope of the present invention, the present invention is limited to the configurations of Figs. 1 to 6 It is self-evident.
