S101: Establish a connection between the positioning terminal and the photographing terminal.

Optionally, the positioning terminal has a terminal for communication, positioning, timing, and the like, and the positioning terminal may further have a function of detecting displacement. For example, the positioning terminal is any one of a smartphone, a tablet, a notebook, a navigator, and the like. Positioning terminal positioning methods include but are not limited to wireless fidelity (Wi-Fi) positioning mode, Bluetooth positioning mode, cellular positioning mode, geomagnetic positioning mode, ultrasonic positioning mode, infrared positioning mode, radio frequency tag positioning mode, Zigbee positioning mode, ultra-wideband radio positioning mode, broadcast signal positioning mode , optical positioning, computer vision positioning and Global Navigation Satellite System (GNSS) positioning methods. The camera terminal is a terminal having functions of photographing, communication, timing, etc., and the photographing terminal may further include functions such as detecting displacement. Camera terminals include, but are not limited to, digital cameras, smart phones, tablets, and the like.

Optionally, a communication connection can be established between the positioning terminal and the camera terminal through a wireless or wired manner. For example, the positioning terminal and the camera terminal can be connected by wireless means such as Wi-Fi, Bluetooth, cellular, or the like. A universal asynchronous communication transceiver (Universal Asynchronous Receiver/Transmitter, UART), a network port, and a universal serial bus (USB) are used to establish a communication connection.

If the distance between the positioning terminal and the photographing terminal is less than a preset threshold, the photographing terminal sends a request for allowing the requested location to the positioning terminal. The preset threshold can be set according to the actual needs according to the actual needs. The setting needs to ensure that the normal communication between the positioning terminal and the photographing terminal and the position where the positioning terminal is positioned as the position of the photographing terminal are not seriously unrealistic, resulting in unacceptable can.

The time threshold can be set according to the needs of the user. When setting, only the time threshold is guaranteed. The value is set to be small enough that in a normal situation, the displacement between the positioning terminal and the photographing terminal is negligible within the time difference between the positioning terminal receiving the positioning request and receiving the last positioning request. The displacement threshold can be set according to the needs of the user. When setting, the displacement between the positioning terminal and the camera terminal can be neglected during the time period between receiving the positioning request and receiving the previous positioning request.

Optionally, the processor 620 of the camera terminal 600 instructs the communication module 610 to establish a communication connection by using a wireless or wired manner. For example, the communication module 610 can establish a communication connection by wireless means such as Wi-Fi, Bluetooth, cellular, or the like. A wired connection such as a Universal Asynchronous Receiver/Transmitter (UART), a network port, or a Universal Serial Bus (USB) establishes a communication connection. The manner in which the communication module 610 establishes a connection is the same as that in the prior art, and details are not described herein again.

Optionally, after the communication module 610 completes establishing the connection, the positioning terminal sends the exchange information to the communication module 610 of the photographing terminal 600, wherein the exchange information may be a character pre-agreed by the positioning terminal and the photographing terminal 600. After receiving the exchange information sent by the positioning terminal, the communication module 610 sends the exchange information to the processor 620. After receiving the exchange information, the processor 620 calculates the distance between the photographing terminal and the positioning terminal 600 by exchanging information from the positioning terminal to the time received by the communication module 610. The distance between the photographing terminal and the positioning terminal 600 is equal to the time between the issuance of the positioning terminal and the reception by the photographing terminal 600 multiplied by the speed at which the information is transmitted. If the processor 620 calculates that the distance between the positioning terminal and the photographing terminal 600 is less than a preset threshold, the processor 620 instructs the display module 640 to display the prompting interface. The prompt interface includes an allow button and a disallow button. If used The user selects the allow button by clicking the touch panel, and the processor 620 allows the communication module 610 to send a request location to the location terminal. If the user selects the disallow button by clicking the touch panel, the processor 620 does not allow the communication module 610 to locate the location. The terminal sends a request for location. The preset threshold can be set according to the actual needs according to the actual needs. The setting needs to ensure that the positioning between the positioning terminal and the communication module 610 of the photographing terminal 600 can be normally communicated, and the position where the positioning terminal is positioned as the position of the photographing terminal 600 is not seriously deficient. It can be unacceptable.

It can be understood that the positioning terminal initiates the connection between the establishing and the photographing terminal 600, and the photographing terminal 600 initiates the connection between the establishing and the positioning terminal. The connection between the positioning terminal 600 and the photographing terminal 600 can be maintained after the power is turned on, and the connection between the positioning terminal and the photographing terminal 600 can be established even when the photographing terminal 600 needs to take a photograph, even in the photographing terminal 600. When the positioning needs to be requested from the positioning terminal, the connection between the positioning terminal and the photographing terminal 600 and the like are established.

Optionally, if the user selects the allow button by clicking the touch panel of the photographing terminal 600 or opens the function of the photographing terminal to send the positioning request by other means, the processor 620 detects that the photographing module 610 performs photographing, and instructs communication. Module 670 sends a location request to the positioning terminal over the established communication connection. Or when the processor 620 detects that the shooting module 610 performs shooting of the photo, the timer is started to perform timing. After the timing time expires, the processor 620 instructs the communication module 670 to send a positioning request to the positioning terminal through the established communication connection. The location request may include at least one of an identifier of the photo or a time of photographing, and the location request may further include an identifier of the photographing terminal and the like. The photo's logo is usually the unique code for the photo and can be used to identify the photo. The time of taking a photo is the time when the user takes a photo to obtain a photo. The identification of the camera terminal is usually a unique code of the camera terminal and can be used to identify the camera terminal. After receiving the instruction of the processor 620, the communication module 670 sends a positioning request to the positioning terminal. Further, the processor 620 instructs the memory 630 to store a photograph obtained by photographing the photograph by the photographing module 610, a photographing time, a logo of the photograph, and the like.

Optionally, after the positioning terminal receives the positioning request sent by the camera terminal, determining the receiving location first Whether the time difference between the request and the previous positioning request is greater than the time threshold, if the judgment result is less than or equal to the time threshold, determining that the positioning is not performed, and if the determination result is greater than the time threshold, further determining the receiving positioning request and receiving the last positioning request If the result of the determination is greater than or equal to the displacement threshold, the positioning is determined not to be performed. If the determination result is greater than the displacement threshold, the positioning is determined. The time threshold can be set according to the needs of the user. When setting, it is only necessary to ensure that the time threshold is set small enough to be within a normal situation, within a time difference between receiving the current positioning request and receiving the last positioning request. The displacement of the positioning terminal and the photographing terminal 600 is negligible. The displacement threshold can be set according to the needs of the user. When setting, the displacement between the positioning terminal and the photographing terminal 600 can be neglected during the time period between receiving the positioning request and receiving the last positioning request, wherein the time period is It can be 10 seconds, 30 seconds or half an hour, and so on. The positioning terminal can calculate the displacement of the positioning terminal by reading sensor data of one or more of the acceleration sensor, the gyro sensor, and the like. For example, the positioning terminal reads sensor data of one or more of the acceleration sensor, the gyro sensor, and the like at the time of receiving the last positioning request, and reads the acceleration sensor, the gyro sensor, and the like at the time of receiving the positioning request. One or more sensor data to calculate the displacement of the positioning terminal during the time period between two positioning requests.

Optionally, if it is determined that the positioning is not performed, the positioning terminal sends a notification that the positioning is not performed to the photographing terminal 600, and at least one of the identification of the photo in the positioning request or the time of photographing; or sending the last position to the photographing terminal. Information, and at least one of the identification of the photo in the location request or the time of the photo. The location information may be latitude and longitude information, or may be address information obtained after parsing the latitude and longitude. The communication module 610 of the photographing terminal 600 receives the correspondingly.

Optionally, if the positioning is determined, the positioning terminal may directly determine the positioning manner according to the specified positioning manner, and obtain current location information. The positioning terminal may also perform positioning according to the remaining power of the positioning terminal or the current environment of the positioning terminal to obtain the current location information, so as to High positioning efficiency and power savings. The specified positioning mode may be wireless fidelity Wi-Fi positioning mode, Bluetooth positioning mode, cellular positioning mode, geomagnetic positioning mode, ultrasonic positioning mode, infrared positioning mode, radio frequency tag positioning mode, Zigbee positioning mode, ultra-wideband radio positioning A combination of any one or more of a mode, a broadcast signal positioning mode, an optical positioning mode, a computer vision positioning mode, and a GNSS positioning mode.

In an embodiment, the positioning terminal selects a positioning mode according to the remaining power. Specifically, the positioning terminal determines whether the remaining power is greater than the power threshold; if the remaining power of the positioning terminal is greater than the power threshold, determining the positioning mode according to the first scanning priority; if the remaining power of the positioning terminal is less than the power threshold, pressing the second scanning first The level determines the positioning method. Among them, the power threshold can be set as needed. The first scan priority and the second scan priority are used to indicate the ordering of the priority levels of the positioning modes. When the positioning mode is determined according to the first scanning priority or the second scanning priority, the positioning mode with the highest priority is selected first. If the positioning mode with the highest priority cannot be used, the positioning mode with the second highest priority is used, and so on. Until the lowest priority positioning method. The first scanning priority is different from the second scanning priority, and the positioning manner in the first scanning priority may be different from the positioning manner in the second scanning priority, or may be the positioning manner in the first scanning priority. The positioning manner in the second scanning priority is the same, but the priority of the positioning mode in the first scanning priority is different from the priority of the positioning mode in the second scanning priority. Generally, the priority levels of the positioning modes in the first scanning priority are arranged in descending order of the accuracy of the positioning mode, and the priority levels of the positioning modes in the second scanning priority are arranged in ascending order according to the power consumption of the positioning mode. For example, the GNSS positioning method has the highest positioning accuracy, the largest power consumption, the lowest positioning accuracy of the cellular positioning mode, and the lowest power consumption, and the Wi-Fi positioning mode is centered. Therefore, the first scanning priority is GNSS positioning mode->Wi-Fi positioning mode->cellular positioning mode, and the second scanning priority is cellular positioning mode->Wi-Fi positioning mode->GNSS positioning mode. Alternatively, the first power threshold and the second power threshold are used to divide the power into three regions, and the positioning terminal determines which region the remaining power falls into, if the remaining power of the positioning terminal falls within the first power. The interval of the threshold is determined according to the first scanning priority. If the remaining power of the positioning terminal falls within a range less than or equal to the second power threshold, the positioning mode is determined according to the second scanning priority level, and the remaining power of the positioning terminal is determined. If the interval falls below the first power threshold and is greater than the second power threshold, the positioning mode is determined according to the third scan priority level. For example, the first scanning priority positioning mode is GNSS positioning mode->Wi-Fi positioning mode->cellular positioning mode, and the second scanning priority positioning mode is cellular positioning mode->Wi-Fi positioning mode->GNSS positioning mode. The third scanning priority positioning mode is Wi-Fi positioning mode->GNSS positioning mode->cellular positioning mode.

In another embodiment, the positioning terminal selects a positioning mode according to the current environment. Specifically, the positioning terminal determines whether the current environment is indoors or outdoors. The positioning terminal can determine whether the current environment of the positioning terminal is indoors or outdoors by reading and analyzing at least one of sensor data such as a light sensor, a barometer, and a temperature sensor. If the current environment of the positioning terminal is indoor, the positioning method suitable for indoor positioning is adopted, for example, Wi-Fi positioning mode, Bluetooth positioning mode, cellular positioning mode, geomagnetic positioning mode, ultrasonic positioning mode, infrared positioning mode, and radio frequency tag positioning mode. At least one of Zigbee positioning mode, ultra-wideband radio positioning mode, broadcast signal positioning mode, optical positioning mode, computer vision positioning mode, and the like acquires current location information; if the current environment of the positioning terminal is outdoor, it is suitable for outdoor use.

After the matching is successful, the processor 620 adds a location tag to the corresponding photo according to the last saved location information. Among them, the head file of the photo usually includes a plurality of different labels for recording shooting time, shutter speed, exposure compensation, focal length and position information, and the like. A location tag is a tag in a header file of a photo that is specifically used to record location information. For example, a location tag is a tag specifically used to record global positioning data in an Exchangeable Image File (EXIF).

Optionally, when determining that the positioning is not performed, the positioning terminal may also determine not to feed back any information to the camera terminal 600. The communication module 610 of the camera terminal 600 does not receive any information fed back by the positioning terminal for a period of time, and notifies the processor 620 to obtain, from the memory 630, the last saved location information before transmitting the positioning request, and according to the communication module. The photo of the photo returned by 610 and/or the shooting time of the photo, and the information of the photo taken by the photo terminal, match the last saved location information with the photographed photo, and then add the corresponding photo according to the last saved location information. Location tag.

The location information or the obtained location information is sent to the processor 620. The processor 620 matches the location information with the captured photo according to the returned last location information or the acquired location information, and some or all of the information included in the location request, and the information that the camera terminal has taken the photo. When matching, the processor 620 can match according to the identifier of the photo returned by the communication module 610 and the identifier of the photograph taken, if the logo of the photo returned by the communication module 610 and the photographed If the identification of the photo is consistent, the matching is successful, or, according to the shooting time of the photo returned by the communication module 610 and the shooting time of the taken photo, if the shooting time of the photo returned by the communication module 610 and the shooting time of the taken photo Consistent, the match is successful. In addition, the processor 620 can also perform matching according to the identification of the photo and the shooting time of the photo at the same time. If the shooting time of the photo is the same as the shooting time of the photographed photo and the photographing time of the photo, the matching is successful. After the matching is successful, the processor 620 adds a location tag to the corresponding photo according to the location information.
