The following takes the Android operating system as an example to introduce the software environment to which the positioning method provided by the embodiment of the present invention is applied.

As shown in FIG. 1 , it is a schematic structural diagram of a possible Android operating system provided by an embodiment of the present invention. In FIG. 1, the architecture of the Android operating system includes four layers, namely: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).

It can run based on the Android operating system as shown in Figure 1. That is, the processor or the terminal device can implement the positioning method provided by the embodiment of the present invention by running the software program in the Android operating system.

The terminal device in this embodiment of the present invention may be a mobile terminal or a non-mobile terminal. Exemplarily, the mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a handheld computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA). ), etc., the non-mobile terminal may be a personal computer (personal computer, PC), a television (television, TV), a teller machine or a self-service machine, etc., which is not specifically limited in the embodiment of the present invention.

The execution body of the positioning method provided by the embodiment of the present invention may be the above-mentioned terminal device, or may be a functional module and/or functional entity in the terminal device capable of implementing the positioning method. The embodiment is not limited. The following takes a terminal device as an example to exemplarily describe the positioning method provided by the embodiment of the present invention.

As shown in FIG. 2, an embodiment of the present invention provides a positioning method, and the positioning method may include the following steps 200-203.

Step 200: The terminal device acquires the target noise value.

Wherein, the target noise value is the noise value in the environment where the terminal device is currently located.

In this embodiment of the present invention, if the terminal device enables the navigation function or the positioning function, then the terminal device can use the built-in microphone sensor of the terminal device to detect (for example, real-time detection) the noise value in the environment where the terminal device is currently located (that is, the above-mentioned target Noise value); other possible sensors may also be used to detect the noise value in the environment where the terminal device is currently located, which may be specifically determined according to actual use requirements, which is not limited in this embodiment of the present invention.

Among them, the noise value is a numerical value to measure the strength of noise, and its unit is usually decibel (dB).

Step 201: The terminal device determines a first noise range, where the first noise range is a noise range corresponding to a first position, and the first position is a position with the highest recommendation priority among at least two positions.

Wherein, the above-mentioned at least two positions are positions obtained by locating the terminal device.

In this embodiment of the present invention, if the terminal device enables the navigation function or the positioning function, then the terminal device can locate the terminal device in real time through a positioning system (eg GPS) to obtain the real-time position of the terminal device.

It should be noted that since the positioning accuracy of GPS is about 10 meters, the positioning of the terminal device through GPS may not be accurate enough. Usually, at least two positions can be obtained, both of which can be used to indicate the terminal device's real-time location. Hereinafter, at least two positions are also referred to as a plurality of recommended positions.

In this embodiment of the present invention, the terminal device may determine the recommendation priorities of the at least two locations, and sort them in sequence according to the recommendation priorities, that is, the locations with higher recommendation priorities are ranked first, and the positions with lower recommended priorities are ranked last. For example, the position with the highest recommendation priority ranks first among at least two positions.

Exemplarily, as shown in FIG. 3 , the terminal device currently has the positioning function enabled. Wherein, the position obtained by the GPS positioning of the terminal device is indicated by the positioning mark 31, and the current interface displays at least two positions 32 with higher recommended priorities, such as "street A", "cell A", "Residential B" and "Shopping mall A", these at least two locations are arranged in order of recommendation priority. Among them, "street A" has the highest recommendation priority and is ranked first. That is, the position obtained by the GPS positioning of the terminal device is currently recommended as "street A".

Further, the terminal device may determine the noise range corresponding to the first position (ie the first noise range) according to the position with the highest recommendation priority among the at least two positions (ie the first position).

Optionally, in this embodiment of the present invention, the above-mentioned first location may be a location with the highest recommended priority among at least two locations, may also be a location indicated by a positioning marker in an electronic map displayed by the terminal device, or may be at least two locations. Any other possible positions in the positions may be specifically determined according to actual usage requirements, which are not limited in this embodiment of the present invention.

In this embodiment of the present invention, the terminal device may pre-store a correspondence between locations and noise ranges (eg, a list), that is, one location corresponds to one noise range. Exemplarily, FIG. 4 shows a schematic diagram of the above list of correspondences between positions and noise ranges.

In this embodiment of the present invention, when the position is known, the noise range corresponding to the known position may be determined based on a preset correspondence relationship.

For example, assuming that the location with the highest recommended priority among the at least two locations is a certain cell (that is, the above-mentioned first location), then the terminal device can determine the noise corresponding to the first location according to the correspondence list shown in FIG. 4 . The range is [10dB, 35dB).

For another example, assuming that the location with the highest recommended priority among the at least two locations is a certain street (that is, the above-mentioned first location), then the terminal device can determine the location corresponding to the first location according to the correspondence list shown in FIG. 4 . The noise range is [60dB, 110dB).

It can be understood that the positions and their corresponding noise ranges shown in FIG. 4 are all exemplary enumerations, that is, the embodiments of the present invention include but are not limited to the above-listed positions and their corresponding noise ranges. In actual implementation, the above-mentioned correspondence between the position and the noise range may also include any other possible position, that is, its corresponding noise range, which may be specifically determined according to actual use requirements, which is not limited in the embodiment of the present invention.

It should be noted that, the embodiment of the present invention may not limit the execution order of step 200 and step 201 . That is, in this embodiment of the present invention, step 200 may be performed first, and then step 201 may be performed; or step 201 may be performed first, and then step 200 may be performed; or step 200 and step 201 may be performed simultaneously. It can be understood that the above-mentioned FIG. 2 is illustrated by taking step 200 first and then executing step 201 as an example.

Step 202: The terminal device determines the target position according to the target noise value and the first noise range.

Wherein, the target position may be a first position or a second position, and the second position is a position different from the first position among the at least two positions.

In this embodiment of the present invention, after acquiring the target noise value and determining the first noise range, the terminal device may compare the target noise value with the first noise range to determine whether the target noise value is within the first noise range, and determine whether the target noise value is within the first noise range. result to determine the target location.

Optionally, with reference to FIG. 2 , as shown in FIG. 5 , in this embodiment of the present invention, the foregoing step 202 may be specifically implemented by the following steps 202 a and 202 b, or steps 202 a and 202 c.

Step 202a, the terminal device determines whether the target noise value is within the first noise range.

In this embodiment of the present invention, if the terminal device determines that the target noise value is within the first noise range, the terminal device may continue to perform the following step 202b; if the terminal device determines that the target noise value is not within the first noise range, the terminal device It is possible to return to continue to perform the above-mentioned step 202c.

Step 202b, the terminal device determines the first position as the target position.

In this embodiment of the present invention, if the terminal device determines that the target noise value is within the first noise range, the terminal device may determine that the first position is the target position.

Exemplarily, assuming that the detected target noise value is 20dB, and assuming that the first location is cell A, it can be determined that the first noise range corresponding to the first location is [10dB, 35dB), then the terminal device can determine the target noise. The value is within the first noise range, which means that it is accurate to use the first position to indicate the current position of the terminal device at this time, so the terminal device can determine that the first position is the target position.

Step 202c: The terminal device determines the second position from the at least two positions according to the information of the at least two positions, and determines the second position as the target position.

In this embodiment of the present invention, if the terminal device determines that the target noise value is not within the first noise range, the terminal device may determine a position different from the first position (that is, from at least two positions) according to the information of the at least two positions. The above-mentioned second position) is the target position.

Exemplarily, assuming that the detected target noise value is 20dB, and assuming that the first position is Street A, it can be determined that the first noise range corresponding to the first position is [60dB, 110dB), then the terminal device can determine the target noise. The value is not within the first noise range, which means that the current position of the terminal device indicated by the first position is not accurate enough at this time, and the position with the highest recommended priority needs to be corrected (that is, the first position is corrected to the second position) , so that the terminal device can determine that the second position is the target position.

It should be noted that, in this embodiment of the present invention, the terminal device may alternatively execute the foregoing step 202b and step 202c, that is, the terminal device may execute the foregoing step 202b, or the terminal device may execute the foregoing step 202c.

Step 203: The terminal device corrects the position with the highest recommendation priority as the target position.

In the embodiment of the present invention, referring to FIG. 3 , due to a certain error in the positioning result of the terminal device through the positioning system, "street A" is not necessarily the real-time position of the terminal device, where "street A", "cell A", Any location in "Cell B" and "Mall A" may be the real-time location of the terminal device, so the terminal device can correct the location with the highest recommended priority, that is, correct the location with the highest recommended priority to be based on the target noise value and the target position determined by the first noise range.

On the one hand, in this embodiment of the present invention, if the terminal device determines that the first position is the target position, the terminal device can modify the position with the highest recommendation priority to the first position, that is, the position with the highest recommendation priority is still the first position.

On the other hand, in this embodiment of the present invention, if the terminal device determines that the second position is the target position, the terminal device may modify the position with the highest recommendation priority from the first position to the second position.

In the embodiment of the present invention, by using GPS positioning and the microphone of the terminal device to co-locate, the positioning accuracy is increased, thereby optimizing the map navigation system. First use GPS positioning to obtain the recommended position, and determine the noise range corresponding to the recommended position; and obtain the noise value of the current environment where the terminal device is located through the microphone; then, determine whether the noise value of the current environment where the terminal device is located is within the noise range , to judge whether the recommended position obtained by positioning is accurate, and correct the inaccurate recommended position, so as to improve the accuracy of the positioning result of the terminal device.

The positioning method provided by the embodiment of the present invention can obtain the target noise value (the target noise value is the noise value in the environment where the terminal device is currently located); and determine the first noise range (the first noise range is corresponding to the first position) The first position is the position with the highest recommended priority among the at least two positions, the at least two positions are the positions obtained by locating the terminal device); and according to the target noise value and the first noise range, determine the target position (The target position is a first position or a second position, and the second position is a position different from the first position among the at least two positions); and the position with the highest recommendation priority is revised as the target position. Through this solution, on the basis of multiple recommended positions obtained by the positioning system of the terminal equipment, and considering the noise value of the current environment of the terminal equipment and the noise range corresponding to the position with the highest recommendation priority, the current Whether the noise value of the environment is within the noise range corresponding to the position with the highest recommended priority, it is determined whether the position with the highest recommended priority is located accurately. Further, the terminal device can correct the position with the highest recommendation priority as the target position. In this way, the embodiment of the present invention can improve the accuracy of the positioning result of the terminal device.

In this embodiment of the present invention, when the terminal device determines that the target noise value is not within the first noise range, and needs to correct the position with the highest recommended priority, the terminal device firstly selects from at least two positions according to the information of at least two positions. Among the positions, the second position is determined, and then the position with the highest recommendation priority is modified from the first position to the second position, wherein, for the method of how the terminal device determines the second position, please refer to the following first embodiment and the first embodiment. Second Embodiment.

first embodiment

Optionally, in this embodiment of the present invention, the information on the at least two locations may include: (1) coordinates of the at least two locations, and (2) noise ranges corresponding to the at least two locations. In this case, the terminal device may determine the second position from the at least two positions according to the coordinates of the at least two positions and the noise range corresponding to the at least two positions.

For the above (1), in the embodiment of the present invention, in the case where the coordinates of the above-mentioned multiple recommended locations (for example, the latitude and longitude of the multiple recommended locations are obtained from GPS positioning), the terminal device may use the coordinates of the first location and the multiple recommended locations. The coordinates of each of the recommended positions are calculated, and the distance between the first position and each of the plurality of recommended positions is calculated, so that a plurality of distance values can be obtained.

Further, the terminal device may determine a position where the distance between the multiple recommended positions and the first position is within a preset range as at least one candidate position, that is, the distance between the at least one candidate position and the first position. within the preset range. The specific value of the preset range may be determined according to actual usage requirements, which is not limited in the embodiment of the present invention.

Exemplarily, the terminal device may determine a position where the distance from the first position is the smallest among the multiple recommended positions as the candidate position. That is, the distance value between the candidate position and the first position is the minimum value among the plurality of distance values.

In this embodiment of the present invention, the terminal device may compare the target noise value with the noise range corresponding to the at least one candidate position. If the target noise value is within the noise range corresponding to one of the at least one candidate position, Then, the terminal device may determine the one candidate location as the second location. That is, the target noise value is within the second noise range, and the second noise range is the noise range corresponding to the second position.

To sum up, in combination with (1) and (2), the terminal device can first determine which positions among the multiple recommended positions have a distance from the first position within a preset range, and determine these positions as at least one candidate position; then, the terminal device can determine which of the at least one candidate position the target noise value is within the noise range corresponding to which candidate position, and determine the candidate position as the second position.

Or, in combination with (1) and (2), the terminal device can first determine which of the multiple recommended locations corresponds to the noise range covering the target noise value, and determine these locations as at least one candidate location; then, the terminal device can determine at least If the distance between one of the candidate positions and the first position is within the preset range, the candidate position is determined as the second position.

For example, referring to Fig. 3, as shown in Fig. 6, assuming that the user is currently in "cell A", the noise value of the environment where the terminal equipment is located (ie the target noise value) is 20dB, and the location with the highest recommended priority is Street A (the corresponding first noise range is [60dB, 110dB), then the terminal device can determine that the target noise value is not within the first noise range, which means that it is not enough to use the first position to indicate the current position of the terminal device at this time. Accurate, the position with the highest recommendation priority needs to be corrected.

Further, the terminal device may select at least one candidate position among the multiple recommended positions, for example, first determine which positions in the multiple recommended positions have corresponding noise ranges that cover the target noise value, and determine these positions as at least one candidate position (eg. "Cell A" and "Cell B", the noise ranges corresponding to the cells both cover the target noise value); is the target location. Referring to FIG. 3 and FIG. 6 , the terminal device may modify the location with the highest recommendation priority from "street A" to "cell A".

It should be noted that FIG. 3 is shown to illustrate the correction result.

Correspondingly, the above-mentioned step 202c can be specifically implemented by the following steps 202c1 and 202c2.

Step 202d, the terminal device acquires a first image, where the first image is an image obtained by photographing the environment where the terminal device is currently located.

In this embodiment of the present invention, when the target noise value is not within the first noise range, the terminal device may photograph the environment where the terminal device is currently located, acquire a first image, and perform image analysis on the first image.

Step 202c1: The terminal device determines at least one candidate location from the at least two locations according to the identifiers of the at least two locations and the first image.

Exemplarily, referring to FIG. 6 , the multiple recommended locations are respectively identified by names such as “street A”, “district A”, “district B”, and “shopping mall A”.

Optionally, in this embodiment of the present invention, the foregoing step 202c1 may be specifically implemented through the following steps 1 to 3.

Step 1. The terminal device determines the first object indicated by the first image.

Wherein, the first object may refer to the content in the first image, such as tall buildings, streets, flowers and trees, and the like. Suppose the first object includes roads and vehicles, which means that the user is currently on the street; or, suppose that the first object includes tall buildings, flowers, and children, which means that the user is currently in the community. The usage requirement is determined, which is not limited in the embodiment of the present invention.

Step 2: The terminal device determines at least one identifier for indicating the first object from the at least two locations according to the identifiers of the at least two locations.

Wherein, at least two positions (ie, multiple recommended positions) each correspond to an identifier. For example, referring to FIG. 6 , multiple recommended locations correspond to identifiers such as "street A", "district A", "district B", and "shopping mall A", respectively.

Step 3: The terminal device determines the location corresponding to the at least one identifier as at least one candidate location.

Wherein, the information of the at least one candidate location includes the coordinates of the at least one candidate location.

Specifically, the terminal device may use the coordinates of the at least one candidate location and the coordinates of the location with the highest recommendation priority to calculate the distance between the at least one candidate location and the location with the highest recommendation priority, and compare the distance between the at least one candidate location and the location with the highest recommendation priority. The position with the closest position distance is determined as the second position, and the second position is determined as the target position.

Referring to FIG. 6 , a specific implementation manner of steps 202d to 202c2 in the positioning method provided by the embodiment of the present invention is described by way of example.

Compared with cell B, cell A is closer to the location with the highest recommendation priority, so the terminal device can determine cell A as the second location and determine the second location as the target location.

It should be noted that, in this embodiment of the present invention, the terminal device may selectively execute the above step 202b and step 202d-step 202c2, that is, the terminal device may execute the above step 202b, or the terminal device may execute the above step 202d-step 202c2 .

Optionally, in this embodiment of the present invention, the first position corresponds to the first target noise range and the second target noise range, the first target noise range is the noise range corresponding to the first position in the first time period, and the second target noise range is The noise range is the noise range corresponding to the first position in the second time period.

Exemplarily, assuming that the first location is a street, since the noise value of the street is higher during the day and the noise value of the street at night is lower, the street may correspond to the noise range in two different time periods of day and night. As shown in Figure 8, the noise range corresponding to the street in the time period of 06:00-23:00 is [80dB, 110dB), and the noise range corresponding to the street in the time period of 23:00-06:00 is [60dB , 80dB).

Correspondingly, the above-mentioned step 201 can be specifically implemented through the following steps 201a-201c.

Step 201a, the terminal device determines a target time, where the target time is the current system time of the terminal device.

Step 201b, when the target time is within the first time period, the terminal device determines the first target noise range as the target noise range.

Step 201c, when the target time is within the second time period, the terminal device determines the second target noise range as the target noise range.

The following examples illustrate specific implementations of steps 201 a to 201 c in the positioning method provided by the embodiments of the present invention.

Assuming that the current system time of the terminal device is 14:20, the terminal device can determine the target time within the time period of 06:00-23:00 according to the correspondence list shown in Figure 8. 80dB, 110dB) is determined as the target noise range.

Assuming that the current system time of the terminal device is 23:30, then the terminal device can determine the target time within the time period of 23:00-06:00 according to the correspondence list shown in Figure 8. Further, the terminal device will set the noise range [ 60dB, 80dB) is determined as the target noise range.

In this embodiment of the present invention, since a specific location corresponds to different noise ranges in different time periods, it is possible to first determine that the current system time of the terminal device is within a certain time period, and then determine the corresponding noise range according to the certain time period. Whether the noise value of the current environment where the terminal device is located is within the noise range, to determine whether the recommended position obtained by positioning is accurate, and to correct the inaccurate recommended position, so that the accuracy of the positioning result of the terminal device can be improved.

Optionally, in this embodiment of the present invention, in addition to the above-mentioned corresponding relationship between the position and the noise range, the corresponding relationship between the position information and the noise range may also be used. Correspondingly, the above-mentioned step 201 can also be specifically implemented by the following steps 201d and 201e.

Step 201d, the terminal device acquires first location information, where the first location information is used to indicate the first location.

Step 201e: The terminal device determines the noise range corresponding to the first location information as the first noise range.

In this embodiment of the present invention, by using the correspondence between the location information and the noise range, in the case of known location information, the noise range corresponding to the location information is determined, and it is further judged whether the noise value of the current environment where the terminal device is located is within this range. In order to determine whether the recommended position obtained by positioning is accurate, and correct the inaccurate recommended position, the accuracy of the positioning result of the terminal device can be improved.

The positioning method provided by the embodiment of the present invention mainly adopts GPS positioning, and uses a microphone to obtain surrounding sounds of a terminal device to perform auxiliary positioning. The positioning method provided by the embodiment of the present invention can solve the following problems of inaccurate positioning in several scenarios:

Scenario 1: People are standing on the side of the road, but the location is displayed in the adjacent cell

GPS is located in the cell. At this time, the microphone is used to obtain strong noise around the terminal device. However, the noise value of the recommended positioning location cell is small. Go to the original GPS positioning position of the cell, and optimize it to the side of the road closest to the cell.

Scenario 2: People are at home, but their positioning is on the road

This situation is similar to scenario 1. The GPS is positioned on the road, and the sound of the home where the terminal device is located is obtained through the microphone. Since the home is relatively quiet and the noise value is small, and the recommended positioning location has a high noise value on the road, and the two noise values are inconsistent, it can be determined that the GPS positioning is wrong, and the positioning position is corrected to the nearest neighborhood.

Scenario 3: When driving and navigating, it is often prompted to turn when the intersection is over

Scenario 3 is caused by slow GPS positioning. At this time, GPS positioning can be assisted by means of a microphone. Because the car is about to turn, the general car will slow down, so that the wind noise in the car will be reduced, and the detour is generally accompanied by the intersection, the car will increase, and the engine noise of the surrounding cars will increase. The noise value is obtained through the microphone and assists positioning according to the noise change , so as to identify the turn in advance, give the turn prompt in advance, and avoid missing.

Scenario 4: The user is at the bus stop and finds the bus to the corresponding destination through mobile phone navigation

The status quo is often inaccurate positioning. The user is not positioned to the current bus stop, but dozens of meters away from the bus stop. The user is directed to go to the current bus stop or to another bus stop, and the user has to manually It is very inconvenient to choose how to get to the destination from the current location.

In the embodiment of the present invention, after adding the microphone to detect the noise value, the sound characteristics around the bus station can be obtained through the microphone. Thereby, it is recognized that the user is already at the nearest bus stop located by the GPS, and the user is directly located to the bus stop.

Scenario 5: Walking Navigation

This scenario is similar to the situation in which the positioning of scenario 1 and scenario 2 is inaccurate, and will not be repeated here.

The positioning method provided by the embodiment of the present invention can be applied to a terminal device. By adopting GPS positioning and using a microphone to assist positioning, judging the noise and noise changes around the terminal device to identify the surrounding scene of the user, and determine whether the GPS positioning is accurate, so as to increase the positioning accuracy Spend.

In addition, in the positioning method provided by the embodiment of the present invention, the interface for obtaining GPS coordinates can be optimized, and the relevant GPS positioning assistance effects can also be realized by each APP itself. Two cases are described.

Solution 1: Optimize the interface for obtaining GPS coordinates. At present, the mobile phone obtains GPS through the interface.

For example, taking ISO as an example, the IOS interface can obtain the latitude and longitude of the current location of the terminal device in real time by calling the CLLocationManager class. code show as below:

This solution is to modify the didUpdateLocations interface of the CLLocationManager class. When calling the interface, pass in the parameter of whether the microphone-assisted positioning is required. It can be not required by default; if necessary, after obtaining the GPS positioning position, directly obtain the audio of the mobile phone microphone, and then compare whether the noise range corresponding to the microphone audio and the positioning position match. For example, on the side of the road, the noise will not be lower than 40 decibels. If the noise range corresponding to the microphone audio and the positioning position does not match, re-acquire the GPS positioning coordinates, and check again whether the noise range corresponding to the microphone audio and the positioning position match. If it is not consistent, correct the positioning coordinates. For example, if the acquired GPS positioning is on the side of the road, and the acquired mobile phone microphone noise is 20 decibels, the GPS positioning coordinates are automatically optimized (corrected) to the nearest nearby cell. The specific implementation process can be seen in FIG. 9 .

It should be noted that this solution is an update of IOS or Android's own SDK, so that APP developers can use it easily, without perception, without modifying the existing application code, and still use the original coordinate acquisition interface. In addition, the IOS SDK update needs to be developed by Apple developers, and the Android SKD development needs to be developed by Google related personnel.

Option 2: Each APP realizes the relevant GPS positioning assistance effect by itself

This solution does not modify the ISO or Android interface itself, but the APP application obtains the GPS positioning coordinates, and then obtains the audio of the mobile phone microphone, and then judges whether the noise value obtained by the microphone is within the noise range corresponding to the positioning position, that is, the noise value of the two inconsistent. If the noise values are inconsistent, obtain the GPS position again, and judge again whether the noise value obtained by the microphone is within the noise range corresponding to the positioning position. If the noise values are still inconsistent, correct the positioning coordinates. The specific implementation process can be seen in Figure 10.
