It should be noted that the method for acquiring a picture by remote control is described from the perspective of a server, and the method for acquiring a picture by remote control can be implemented as a computer program on a remote network device by programming. Implementation, including but not limited to computers, network hosts, a single web server, multiple network server sets, or multiple The cloud formed by the server.

Referring to FIG. 1, an exemplary embodiment of a method for acquiring a picture by remote control according to the present invention specifically includes the following steps:

S11. Receive a picture acquisition instruction that includes geographic information.

The mobile terminal of the present invention is installed with an application program capable of communicating with the photographing device and the server, and the mobile terminal loading the application program uploads the current geographical location information of the mobile terminal to the server through the network at any time; and loading the application on the mobile terminal When the program is sent, the server sends a verification request with the verification information, and the server verifies the mobile terminal. For the mobile terminal that passes the verification, the server end saves the communication interface of the mobile terminal, and the communication interface may be a phone number or Unique feature information such as IP address. In an embodiment of the present invention, the driving recorder is used as a photographing device controlled by the mobile terminal. In order to facilitate real-time data transmission, the driving recorder and the mobile terminal establish communication in advance based on the local area network to realize mutual communication.

When the image acquisition instruction received by the server includes a specific location information instead of geographic area information, in order to expand the range of image capture, it is convenient for all-round capture detection to reduce the missed rate of effective pictures, and also needs The received location information is expanded to include geographic area information of the location information.

Specifically, in an embodiment of the present invention, after parsing the location information from the received image acquisition instruction, the server invokes an electronic map of the server, converts the location information into latitude and longitude coordinates, and specifies the location information. The coordinates corresponding to the geographical location are centered, and the surrounding geographical area included in a certain radius is used as the geographic information to be searched.

Further, referring to FIG. 1, in the method of the present invention, the method further includes the steps of:

S12. Find multiple mobile terminal communication interfaces that match geographic information.

S13. Broadcast a capture instruction to the mobile terminal communication interface.

The server receives the current geographic location information of each terminal sent by the mobile terminal loaded with the application, and parses the geographic information that needs to be detected according to the received image acquisition instruction, and finds which mobile terminal's current location is exactly located in the geographic information. Within the geographic area, a communication interface determining the plurality of mobile terminals is determined to broadcast a capture instruction to a mobile terminal communication interface belonging to the geographic area. Specifically, the step of the server broadcasting a snap instruction to the mobile terminal belonging to a specific area may be implemented by the following two embodiments.

1. In one embodiment of the invention, the server looks up to determine that the geographic area belongs to the upload The IP address of the plurality of mobile terminals of the geographical location information covered by the information; the capture instruction is sent to the IP address. After the server finds the mobile terminal located in a specific geographic area, the communication interface, such as an IP address, of the mobile terminal is obtained from the current geographical location information uploaded by the mobile terminal, and the capture instruction is sent to the mobile terminal through the IP address. It should be noted that, when the mobile terminal sends its current geographical location information to the server, the IP address of the mobile terminal is optionally sent to the server at the same time; or, when the mobile terminal sends the current geographical location information to the server, The IP address of the mobile terminal is not sent to the server, and the server can obtain the communication interface of the terminal by analyzing the transit information of the received data packet.

The server encapsulates the data with the capture command with json or xml and sends it to the IP address of the mobile terminal in the specific area. The sending manner of the capture instruction in this embodiment is effective only when the application for controlling the capture in the mobile terminal is turned on. Only when the mobile terminal application is turned on can the shooting device be controlled to perform the capture in response to the capture instruction received from the server. Suitable for general scenes.

It should be noted that, the manner in which the mobile terminal obtains the current geographic location of the local device may be the GPS acquisition of the local device, or the location of the base station based on the network operator, which is not limited in this embodiment.

2. In still another embodiment of the present invention, the server looks up a mobile number identifying a plurality of mobile terminals that have uploaded geographic location information pertaining to the range covered by the geographic area information; and sends a snap instruction to the mobile number. The manner in which the snapshot instruction is sent in this embodiment is suitable for a relatively urgent situation, and is also effective for a mobile terminal that does not open the corresponding application, that is, the method can call more mobile terminals to perform a snapshot operation in response to the capture instruction.

Specifically, in this embodiment, after the server finds the mobile terminal located in a specific geographical area, the mobile terminal number of the mobile terminal is obtained from the current geographical location information uploaded by the mobile terminal, and the mobile terminal number is sent to the mobile terminal by using the mobile phone number. Capture instructions. It should be noted that the server stores a correspondence table between the mobile phone number input by the mobile terminal during registration or verification and the IP address of the mobile terminal, and the server analyzes the transit information of the data packet of the current geographic location information sent by the received mobile terminal. Obtain the IP address of the terminal and find the mobile phone number corresponding to the IP address. The SMS platform is invoked, and the server may send the snapshot instruction to the corresponding mobile phone number in the form of short message, so that the mobile terminal carrying the mobile phone number SIM card executes the capture instruction. The mobile terminal background service program monitors the capture instruction in the form of the short message, and the application that can control the shooting device to perform the capture is controlled from the startup, and the shooting device is controlled to perform the capture.

In summary, after receiving the picture acquisition instruction with the target geographic information, the server broadcasts a capture instruction to the communication interface of the mobile terminal that uploaded the current geographical location information of the specific geographic area, so that the mobile terminal performs the snapshot. Command, control the shooting device to capture the picture.

Further, referring to FIG. 1, the method of the present invention further includes a step S14 of receiving a picture captured in response to the snap instruction.

The server receives the picture fed back by the mobile terminal through the network. In order to ensure the transmission speed of the picture, the picture transmitted from the mobile terminal is compressed into a data packet of a certain format, and after receiving the compressed picture data packet, the server end parses the data packet. Get the picture. In one embodiment of the invention, the server and the mobile terminal communicate via a 3G or 4G network.

Further, in order to selectively control the mobile terminal to capture more high-quality pictures in accordance with the target scene, the bandwidth is increased to facilitate the server to receive more valid pictures in time. Improve the proportion of valid data in the pictures captured by the mobile terminal, reduce the missed rate of valid evidence, and facilitate illegal evidence collection afterwards. Referring to FIG. 2, the method of the present invention further includes the following steps:

S151. According to a preset grading rule, the received pictures are hierarchically processed according to the definition or/and the capture angle in real time, and the pictures are classified into different levels;

S152. Acquire, according to a picture of a specific level, a mobile terminal communication interface that uploads the picture, and send a snapshot instruction that is used to improve the capture frequency to the communication interface;

S153. Send a request for increasing a transmission bandwidth of the mobile terminal corresponding to the communication interface to the remote service address.

Specifically, after the server receives the image, the image is classified in real time based on a preset hierarchical rule to obtain a high quality picture that is closest to the target scene. The following embodiments briefly analyze the preset grading rules.

In an embodiment of the present invention, the preset grading rule refers to identifying the number of faces in the picture, and grading the corresponding picture according to the numerical value of the number of faces; wherein the number of faces is greater than one The corresponding picture of the preset threshold is classified as the specific level. Specifically, a certain face tracking algorithm is used to identify the number of faces appearing in the picture, and the picture with the largest number of faces is classified as the highest level, and the picture with the number of faces is classified as the next highest level... …,And so on. When the number of faces is greater than a predetermined threshold, for example, the preset threshold is 40, that is, when the number of faces is greater than 40, an illegal event such as illegal aggregation may occur in the target scene marked by the picture. Pictures with a number of faces greater than the preset threshold are classified as specific levels. It should be noted that the face tracking algorithm used by the server is an algorithm commonly used in the prior art or an improved algorithm based on the existing face tracking algorithm, or a face recognition algorithm suitable for the embodiment in the future. For example, the Adaboost algorithm, the Camshift algorithm, and the like which are commonly used in the prior art, the specific face tracking algorithm is not limited in this embodiment.

2. In still another embodiment of the present invention, the preset grading rule refers to identifying the sharpness of the picture, and grading the corresponding picture according to the numerical range of the sharpness; wherein the sharpness is greater than a preset threshold The corresponding picture is categorized as the specific level. Specifically, the clarity of the picture is judged by a certain picture sharpness evaluation method. For example, the grayscale change function can be used to calculate the change of the gray value of the image, and the focused image contains more grayscale changes than the out-of-focus image; or, the gradient function is used to evaluate the grayscale of the image, generally the better the focus, The sharper the edges of the picture, the larger the image gradient value. In this embodiment, the picture with the best picture clarity is classified as the highest level, and the picture with better definition is classified as the next highest level, and so on. When the sharpness of the picture is greater than a predetermined threshold, the picture is classified as the specific level.

In a further embodiment of the present invention, the preset grading rule refers to identifying an offset angle of a picture shooting angle with respect to a central axis of the target scene, and grading the corresponding picture according to the magnitude of the offset angle. The target scene is a picture area whose number of faces identified in the picture is greater than a preset threshold; wherein the corresponding picture whose offset angle is less than a preset threshold is classified as the specific level. Specifically, the server side identifies, according to a certain face tracking algorithm, an area in which the number of faces in the picture is greater than a preset threshold. For example, in an exemplary embodiment of the present invention, the threshold is 25, and the area where the number of faces is gathered is set as the target area, and the area that is characterized may be the target scene that needs to be captured, with the central axis of the area For the reference line, the offset angle of the shooting angle of the picture relative to the reference line is determined based on a certain algorithm. The image with the smallest offset angle is classified as the highest level, and the image with the smaller offset angle is classified as the next highest..., and so on. The corresponding picture whose offset angle is less than a preset threshold is classified into the specific level, for example, the offset angle is set to 15 degrees, and when the offset angle of the picture is less than 15 degrees, the mobile terminal that provides the picture is characterized. The offset of the shooting position of the controlled photographing device is relatively small.

It should be noted that the grading rules in the foregoing embodiments are not separate grading rules, and each grading rule can be combined to judge the shooting quality of the picture and the matching degree with the target scene, and is integrated based on the weight values of each grading rule. Analysis, the above grading rules are pre-set on the server The algorithm of the end is automatically analyzed and implemented. Of course, for the grading of pictures with complicated scenes, the grading rules may also be implemented based on the subjective evaluation of the user, and the user sends a hierarchical instruction to the server.

After obtaining a picture of a specific level, obtaining a communication interface of the mobile terminal that provides a picture of a specific level, and transmitting a snapshot instruction indicating that the capture frequency is increased to the communication interface, that is, sending the increased capture frequency to the mobile terminal capable of providing a high-quality picture. Capture instructions. It should be noted that the server obtains the communication interface of the mobile terminal that provides the picture from the picture. For example, the communication interface is an IP address, which can be implemented by the following three embodiments.

1. In an embodiment of the present invention, when uploading the picture, the mobile terminal adds the communication interface of the terminal to the accompanying picture in the attribute information of the picture. For example, for a picture in jpg and jpeg format, the file Exif attribute includes a tag User Comments, which can be customized by the user, and the tag can be used to provide communication interface information of the mobile terminal providing the picture. Stored in the Exif property of the image. Similarly, for other formats of the picture, the communication interface information of the mobile terminal that can provide the picture is stored in the attached information of the picture, such as a picture in the format of bmp, png, etc., and is not illustrated here. In this way, the server can obtain the communication interface that provides the picture by parsing the attribute information of the obtained picture, and send a capture instruction for increasing the capture frequency to the communication interface. For example, the server encapsulates the snapshot instruction with json or xml, and then sends the snapshot instruction to the The communication interface of the mobile terminal.

2. In another embodiment of the present invention, when uploading the picture to a server, the mobile terminal attaches a data table that is associated with the picture, wherein the data table stores communication of the mobile terminal that provides the picture. Unique feature information such as interface. In this way, the server can obtain a communication interface of the mobile terminal that provides the picture by searching a data table corresponding to the picture, and send a capture instruction that increases the capture frequency to the communication interface. For example, the server encapsulates the snapshot instruction with json or xml and sends it to the mobile terminal communication interface.

3. In still another embodiment of the present invention, the server may obtain the communication interface of the terminal by analyzing the relay information of the received picture data packet. The server can then send a capture instruction to increase the capture frequency to the communication interface through the analyzed communication interface. For example, the server encapsulates the snapshot instruction with json or xml and sends it to the mobile terminal communication interface.

Further, in order to ensure more real-time uploading of a certain level of pictures uploaded to the server, it is also necessary to increase the transmission bandwidth of the mobile terminal providing a certain level of pictures. The server sends a request for increasing the transmission bandwidth of the mobile terminal corresponding to the communication interface to the remote service address, to The transmission bandwidth of the mobile terminal is high. The remote service address is an effective address of the communication server with the bandwidth improvement function provided by the network operator. In an embodiment of the present invention, the network operator provides the server with a specific number, and the server sends a request for increasing the transmission bandwidth of the mobile terminal corresponding to the communication interface to the specific number in the form of a short message, where the request includes There is a target IP address, a target bandwidth, and the like of the mobile terminal that needs to increase the bandwidth, so that the network operator increases the transmission bandwidth of the mobile terminal corresponding to the target IP address to the target bandwidth value; or, in another embodiment of the present invention The network operator provides the server with a remote server address, and the server sends, in the form of an instruction, the request for increasing the transmission bandwidth of the mobile terminal corresponding to the communication interface to the remote server address, where the request includes the bandwidth to be increased. The target IP address, the target bandwidth, and the like of the mobile terminal, so that the network operator increases the transmission bandwidth of the mobile terminal corresponding to the target IP address to the target bandwidth value.

In order to facilitate the understanding of the implementation of the method for acquiring pictures by remote control in the present invention, it is necessary to briefly introduce the implementation of the method from the perspective of the mobile terminal. The invention uses an Android mobile phone as a mobile terminal, and takes a driving recorder with a camera, a processor and a communication module as a shooting device controlled by the mobile terminal as an example to illustrate the specific implementation of the method. The mobile terminal is provided with an application capable of communicating with the server and the photographing device.

It should be noted that the local area network may be a local area network such as Bluetooth or WIFI that supports peer-to-peer (such as AD-Hoc, WiFi Direct, or SmartLink) connection technologies, and the use of the above-mentioned local area network to transmit pictures to the mobile terminal does not consume traffic charges, and Suitable for in-car environments without Wifi coverage.

The mobile terminal accesses the server to download and install the server-side application, and sends the verification information to register with the server, and can register to the server by inputting the mobile terminal's mobile phone number. A mobile terminal capable of communicating with the server is loaded, and the current geographical location information is periodically sent to the server, and the server sends a capture instruction to the mobile terminal in the specific area. It should be noted that the manner in which the mobile terminal acquires the current geographic location may be a call. The GPS acquisition of the local device may also be based on the location of the base station of the network operator. This embodiment does not limit this.

The mobile terminal receives the capture instruction sent by the server through the remote interface, and presets the point-to-point The transmission channel automatically sends the capture command to the driving recorder. In response to the capture command, the background recorder controls the current frame picture in the captured video data as the captured picture and automatically transmits it to the mobile terminal through the point-to-point transmission channel. The mobile terminal automatically uploads the picture fed back by the driving recorder to the server through the 3G or 4G network, and in order to ensure the real-time performance of the picture transmission, the mobile terminal uploads the picture through the remote interface based on the real-time transmission protocol RTP. It should be noted that, when the mobile terminal uploads the image to the server through the background service program, the communication interface information of the mobile terminal may be uploaded, so that the server returns a snapshot instruction that improves the capture frequency based on the communication interface specified in the communication interface information. . The capture instruction for improving the capture frequency includes a target number of captures per second, and when the image is captured from the video data, the target number is mathematically related to the number of frames played per second in the video data, and may be related to the number of frames. The same or a half or a third of the number of frames, etc., the mathematical correlation is determined according to the actual situation, which is not limited by the present invention. . In an exemplary embodiment, the driving recorder video frame as the photographing device is 25 frames/s, and the target number of captures per second received from the mobile terminal is 25, to obtain all static pictures played every second in the video. , reduce the missed rate of effective pictures.

Further, after the server receives the picture fed back by the mobile terminal, the picture is divided into different levels according to a preset grading rule in real time; and the picture with a good picture capturing angle or high definition is classified into a specific level, and the specific level is provided. The picture of the mobile terminal sends a snap command that increases the snap frequency. The mobile terminal receives the snapshot instruction of the server-side feedback to improve the capture frequency, and controls the driving recorder to increase the capture frequency to obtain more pictures with good shooting angle or high definition. In summary, in the present invention, the mobile terminal itself or the camera device controlled by the mobile terminal is used as a movable imaging device for monitoring, when the server wants to monitor a certain geographical area where an illegal behavior has occurred or may occur. In the security situation, according to the current geographic location uploaded by the mobile terminal, the capture instruction is broadcast to the communication interface of the plurality of mobile terminals located in the specific area, and the server receives the picture obtained by the mobile terminal in response to the capture instruction. The mobile terminal is used as the camera device to remotely control the mobile terminal to obtain the target picture, which is convenient for comprehensive monitoring of illegal behaviors, and is not easy to be illegally destroyed, thereby reducing the construction cost, high reliability and easy maintenance of the monitoring system.
