In practical application, optionally, the personal terminal may be in communication connection with a remote controller of the drone. If the personal terminal is a smart phone, in a possible implementation manner, the smart phone can be in communication connection with a remote controller of the unmanned aerial vehicle in a wired manner. First image data shot by the unmanned aerial vehicle can be received through a first application service program running in the personal terminal, and optionally, the process may be specifically implemented as: the method comprises the steps of receiving first image data shot by the unmanned aerial vehicle from the remote controller by running a first application service program.
In the process, the unmanned aerial vehicle shoots first image data, the first image data is coded, then the first image data is transmitted to the remote controller, and then the remote controller can transmit the first image data to a first application service program running in the personal terminal.
After the first application service program receives the first image data, the first application service program may pre-process the first image data, and process the first image data into the second image data through a pre-processing process. It will be appreciated that the pre-processing may comprise a plurality of refined processes and that the pre-processing may comprise at least a decoding process of the first image data. The first image data is image data subjected to encoding processing, and decoding processing of the first image data can be completed through the first application service program to obtain second image data.
After obtaining the second image data through the decoding process within the first application service, the first application service may transfer the second image data to the second application service. The second application service program can be an application service program installed and operated by the personal terminal system by default or a third-party application service program installed and operated by the user. Alternatively, the second application service may include a system camera application service of the personal terminal, a personal social application service, or a video call application service.

It can be understood that, in the process of transmitting the first image data to the personal terminal by the remote controller of the unmanned aerial vehicle, a transmission protocol needs to be used, and because the type of the transmission protocol in practical application is not unique, if the transmission process of the first image data needs to be completed successfully, the first application service program running in the remote controller and the personal terminal needs to negotiate the transmission protocol used consistently, and then the first application service program can also complete the protocol analysis processing of the first image data. Based on this, optionally, the preprocessing may further include a protocol parsing process, which is performed before the decoding process.
Optionally, the method provided in the embodiment of the present invention may further include: running an image display selection interface of a second application service program, and detecting image selection operation of a user on the image display selection interface; when the first operation of the user on the image display selection interface is detected, the second application service program is operated to display the image shot by the camera of the personal terminal on the image display interface of the second application service program and/or the sharing operation is performed on the image shot by the camera of the personal terminal, so that the other personal terminal can obtain and display the image shot by the camera of the personal terminal. Accordingly, the process of operating the second application service program to display the second image data on the image display interface of the second application service program and/or perform sharing operation on the second image data to enable the other personal terminals to acquire and display the second image data may be implemented as follows: when second operation of the user on the image display selection interface is detected, second image data are displayed on the image display interface of the second application service program and/or sharing operation is performed on the second image data by operating the second application service program, so that other personal terminals can acquire and display the second image data.
It is understood that the personal terminal may have a camera, the second application service program may display an image display selection interface, and when the user performs the first operation on the image display selection interface, the image taken by the personal terminal having the camera may be displayed on the image display interface of the second application service program, and/or the image taken by the personal terminal having the camera may be shared with other personal terminals. On the other hand, when the user performs the second operation in the image display selection interface, the image shot by the unmanned aerial vehicle can be displayed in the image display interface of the second application service program, and/or the image shot by the unmanned aerial vehicle can be shared with other personal terminals.
Alternatively, the second application service program may be a system camera application service program of the personal terminal, and the process of running the second application service program to display the second image data on the image display interface of the second application service program may be implemented as follows: and displaying the second image data on the image display interface of the system camera application service program by running the system camera application service program.
Optionally, the method provided in the embodiment of the present invention may further include: running an image display selection interface of a system camera application service program, and detecting image selection operation of a user on the image display selection interface; when a first operation of the user on the image display selection interface is detected, the system camera application service program is operated to display the image shot by the camera on the image display interface of the system camera application service program. Accordingly, the above process of displaying the second image data on the image display interface of the system camera application service program by running the system camera application service program may be implemented as follows: and when a second operation of the user on the image display selection interface is detected, displaying second image data on the image display interface of the system camera application service program by running the system camera application service program.
As shown in fig. 2, fig. 2 is an image display selection interface of the system camera application service program, and three screen selection options are set under the interface, and include a front camera option, a rear camera option, and an unmanned aerial vehicle camera option from left to right in sequence. When the user selects the front camera option or the rear camera option, the system camera application service program can call and display the image shot by the camera of the personal terminal in the image display interface, and when the user selects the unmanned aerial vehicle camera option, the system camera application service program can acquire second image data from the first application service program and display the image shot by the unmanned aerial vehicle in the image display interface based on the second image data.
The second application service program may be a video call application service program in addition to the system camera application service program. When the second application service program includes a video call application service program, the process of executing the sharing operation on the second image data by running the second application service program to enable the other personal terminals to acquire and display the second image data may be implemented as follows: and transmitting the second image data to other personal terminals by operating the video call application service program so that the other personal terminals acquire and display the second image data.
In practical application, it is assumed that a user performs a video call with another user holding another personal terminal through a video call application service program running in the personal terminal, and the user can start a front camera or a rear camera of the personal terminal with a camera, so that the user can share an image of the user or an image of an environment where the user is located with another user for viewing. As shown in fig. 3, when the user selects to turn on the camera of the unmanned aerial vehicle, the user may forward the second image data to the server corresponding to the video call application service program through the network, and then the server forwards the second image data to another personal terminal held by another user through the network, and the another user views the image shot by the unmanned aerial vehicle in the video call application service program running in the other personal terminal.
In addition, optionally, the personal terminal may not only send the second image data to other personal terminals through a sharing operation, but also display the second image data in a local image display interface through the second application service program. Like this, the image that unmanned aerial vehicle shot can be looked over to another user of not only conversing with the user, and the user oneself also can look over the image that unmanned aerial vehicle shot.
The embodiment of the invention provides a plurality of methods for transmitting second image data from a first application service program to a second application service program. Optionally, the second image data is transmitted in a shared memory, a transport layer or a socket communication mode by running the first application service program.
Optionally, the preprocessing further includes an encoding process, wherein the encoding process is subsequent to the decoding process, and the second image data includes decoded image data in a decoded state after the decoding process and encoded image data in an encoded state after the encoding process is performed on the decoded image data. Accordingly, the process of operating the second application service program to display the second image data on the image display interface of the second application service program and/or perform sharing operation on the second image data to enable the other personal terminals to acquire and display the second image data may be implemented as follows: the second application service program is operated to display the decoded image data on the image display interface of the second application service program, sharing operation is performed on the encoded image data, so that other personal terminals can acquire the encoded image data, and the image shot by the unmanned aerial vehicle is displayed based on the encoded image data.
Optionally, a third application service program may be installed and run on the personal terminal, and the third application service program may be, for example, a system camera application service program. The method provided by the embodiment of the invention can also comprise the following steps: transmitting the decoded image data by operating the first application service program so that the third application service program acquires the decoded image data; and displaying the decoded image data on an image display interface of the third application service program by running the third application service program.
It is understood that if an image is to be displayed, the image needs to be image data subjected to decoding processing, and if an image is to be transmitted, image data subjected to encoding processing may be transmitted in view of saving data transmission bandwidth, which may save bandwidth occupied when transmitting image data.
As shown in fig. 4, in the first application service program, the data transceiver module may acquire the first image data from the remote controller, and then the data transceiver module transmits the first image data to the protocol analysis module, the protocol analysis module performs protocol analysis processing on the first image data, and then the protocol analysis module transmits the first image data after the protocol analysis processing to the video decoding module, and the video decoding module performs decoding processing on the first image data after the protocol analysis processing to obtain decoded image data. And then the video decoding module transmits the decoded image data to the distortion calibration module, and the distortion calibration module can perform distortion calibration processing on the decoded image data so as to output image data with better image quality. The distortion calibration module may transmit the distortion calibrated image data to the data transmission module and the full frame encoding module.
The data sending module can send the image data subjected to distortion calibration to a system camera application service program and a video call application service program, and the system camera application service program can receive the image data subjected to distortion calibration through the first data receiving module and is used for displaying the image data subjected to distortion calibration in an image display interface. The full-frame coding module can code the image data subjected to distortion calibration to obtain coded image data, then transmits the coded image data to the cache video module and the data transmitting module, and the data transmitting module transmits the coded image data to the video call application service program.
The video call application service program can receive the image data subjected to distortion calibration through the second data receiving module so as to display the image data subjected to distortion calibration in a local image display interface, and can also receive the encoded image data through the third data receiving module and send the encoded image data to the server through the network so as to finally send the encoded image data to other personal terminals.
Since the first image data is image data having the first encoding format and the encoded image data is image data having the second encoding format, the first image data needs to be decoded and encoded, and the encoded image data obtained by encoding is different from the encoding format of the first image data.
Alternatively, the first image data may be image data encoded by a non-h.264 encoding method, and the encoded image data may be image data encoded by an h.264 encoding method.
In one possible implementation, the first image data may be converted by a decoding process into YUV (a color coding method, Y denotes brightness (Lumi nance or Luma), i.e., gray scale value, and U and V denote Chroma (Chroma nance or Chroma) which is used to describe the color and saturation of an image for specifying the color of a pixel) image data, which is a data format that can be used for direct display on a display screen. And then, encoding the YUV image data by adopting an H.264 encoding mode to obtain encoded image data encoded by adopting the H.264 encoding mode.
Alternatively, the preprocessing may further include an encoding process that is subsequent to the decoding process, and the second image data includes encoded image data in an encoded state after the encoding process is performed. Accordingly, the process of operating the second application service program to display the second image data on the image display interface of the second application service program and/or perform sharing operation on the second image data to enable the other personal terminals to acquire and display the second image data may be implemented as follows: the method comprises the steps of decoding the encoded image data by operating a second application service program to obtain decoded image data, displaying the decoded image data on an image display interface of the second application service program, and performing sharing operation on the encoded image data to enable other personal terminals to acquire the encoded image data and display images shot by the unmanned aerial vehicle based on the encoded image data.
Optionally, a third application service program may be installed and run on the personal terminal, and the method provided in the embodiment of the present invention may further include: transmitting the encoded image data by operating the first application service program so that the third application service program acquires the encoded image data; and decoding the encoded image data by operating the third application service program to obtain decoded image data, and displaying the decoded image data on an image display interface of the third application service program.
As shown in fig. 5, in the first application service program, the data transceiver module may obtain the first image data from the remote controller, and then the data transceiver module transmits the first image data to the protocol analysis module, the protocol analysis module performs protocol analysis processing on the first image data, and then the protocol analysis module transmits the first image data after the protocol analysis processing to the video decoding module, and the video decoding module performs decoding processing on the first image data after the protocol analysis processing, so as to obtain the first decoded image data a. Then, the video decoding module transmits the first decoded image data a to the distortion calibration module, and the distortion calibration module can perform distortion calibration processing on the first decoded image data a to output image data with better image quality. The distortion calibration module may transmit the distortion calibrated image data to the full frame encoding module. The full-frame coding module can code the image data subjected to distortion calibration to obtain coded image data, then transmits the coded image data to the cache video module and the data transmitting module, and the data transmitting module transmits the coded image data to the system camera application service program and the video call application service program.
In the system camera application service program, the first data receiving module can receive the coded image data, then the first data receiving module can transmit the coded image data to the first video decoding module, and the first video decoding module decodes the coded image data to obtain decoded image data B so as to display the decoded image data B in an image display interface of the system camera application service program.
In the video call application service program, the second data receiving module can receive the encoded image data, and then the second data receiving module can transmit the encoded image data to the second video decoding module and simultaneously transmit the encoded image data to the server through the network, so as to finally transmit the encoded image data to other personal terminals. After receiving the encoded image data, the second video decoding module may perform decoding processing on the encoded image data to obtain decoded image data C, so as to display the decoded image data C in an image display interface of the video call application service program.
In another example, as shown in fig. 6, in the first application service program, the data transceiver module may obtain first image data from the remote controller, and then the data transceiver module transmits the first image data to the protocol parsing module, and the protocol parsing module performs protocol parsing on the first image data, and then the protocol parsing module transmits the first image data after the protocol parsing to the video decoding module, and the video decoding module performs decoding processing on the first image data after the protocol parsing, so as to obtain decoded image data. And then the video decoding module transmits the decoded image data to the distortion calibration module, and the distortion calibration module can perform distortion calibration processing on the decoded image data so as to output image data with better image quality. The distortion calibration module can transmit the image data subjected to distortion calibration to the data transmission module and the full-frame coding buffer video module.
The data sending module can send the image data subjected to distortion calibration to a system camera application service program and a video call application service program, and the system camera application service program can receive the image data subjected to distortion calibration through the first data receiving module and is used for displaying the image data subjected to distortion calibration in an image display interface.
The video call application service program can receive the image data subjected to distortion calibration through the second data receiving module, the second data receiving module can transmit the image data subjected to distortion calibration to the video coding module, the video coding module can perform coding processing on the image data subjected to distortion calibration to obtain coded image data, and then the coded image data is transmitted to the server through the network so as to finally transmit the coded image data to other personal terminals.
In summary, for the above examples corresponding to fig. 4 to fig. 6, in the example corresponding to fig. 6, the first application service program directly sends the distortion-calibrated image data to the second application service program, and the distortion-calibrated image data may be YUV image data, and the data volume of the YUV image data is large, so when the distortion-calibrated image data is transmitted across processes, the distortion-calibrated image data may be sent from the first application service program to the second application service program in a shared memory or transmission layer communication manner. And a shared memory or transmission layer communication mode is adopted, so that the data transmission efficiency can be improved. In addition, because the data volume of the YUV image data is large, when the video call application service program performs the sharing operation, the video call application service program may perform encoding processing on the image data subjected to distortion calibration so as to send the encoded image data with a small data volume to the server. Optionally, based on this, the YUV image data is transmitted to the second application service program by running the first application service program in a shared memory or transport layer communication manner.
In the example corresponding to fig. 5, the first application service program directly sends the encoded image data to the second application service program, and the data size of the encoded image data is small, so when the encoded image data is transmitted across processes, the encoded image data can be sent from the first application service program to the second application service program in a socket (socket, which is an abstraction of an endpoint for bidirectional communication between application processes on different hosts in a network) communication manner. Since the second application service program receives the encoded image data, in order to display the image captured by the unmanned aerial vehicle in the image display interface, the encoded image data needs to be decoded to normally display the image captured by the unmanned aerial vehicle. The encoded image data may be image data encoded by an h.264 encoding system. Based on this, optionally, the image data encoded by the h.264 encoding method is transmitted to the second application service program in a socket communication manner by running the first application service program.
Fig. 4 corresponds to an example in which a first application service simultaneously transmits distortion-corrected image data and encoded image data to a second application service. When the distortion-calibrated image data and the encoded image data are transmitted across processes, the distortion-calibrated image data and the encoded image data can be sent from the first application service program to the second application service program in a shared memory or transmission layer communication mode. Like this, if need show the image that unmanned aerial vehicle shot in the image display interface of second application service program, then directly use the image data that warp the calibration can, if need carry out the sharing operation through second application service program, then can directly use the code image data, need not second application service program and oneself again encode or decode and handle, and then can effectively reduce system load. The image data subjected to distortion calibration can be YUV image data, and the coded image data can be image data coded by adopting an H.264 coding mode. Optionally, based on this, the first application service program is run to transmit the image data and the YUV image data encoded by the h.264 encoding method to the second application service program in a shared memory or transport layer communication manner.
By adopting the method and the device, when the personal terminal is used, the first image data shot by the unmanned aerial vehicle can be received through the first application service program, then the first application program finishes the preprocessing of the first image data, such as the decoding processing of the first image data, so as to obtain the second image data, the first application service program can transmit the second image data to the second application program, the second application program displays the second image data on the image display interface of the second application service program, and the second application program can also execute the sharing operation on the second image data so as to enable other personal terminals to obtain and display the second image data. Through the mode, the personal terminal can not only adopt the camera to complete shooting operation, but also can carry out shooting operation through the unmanned aerial vehicle camera, and the image shot by the unmanned aerial vehicle is displayed at the personal terminal or shared to other personal terminals, so that the flexibility of using the shot image of the unmanned aerial vehicle in the application service program of the personal terminal is improved, and more application service programs can use the shot image of the unmanned aerial vehicle.
