Based on the mobile terminal hardware structure and the communication network system, the invention provides various embodiments of the remote face recognition method.

In an embodiment, the remote face recognition method is applied to a screen projection end, and referring to fig. 3, fig. 3 is a schematic flow diagram of a first embodiment of the remote face recognition method of the present invention. As shown in fig. 3, the remote face recognition method includes:

step S10, acquiring camera data sent by a screen projection end;

in this embodiment, the screen projection end may be a device such as a mobile phone, a computer, a tablet, a server, and the like, and the projected screen may be a device such as a mobile phone, a computer, a tablet, and the like. And the screen projection end and the screen to be projected end establish screen projection connection, and transmit the picture of the local end to the screen to be projected end in real time.

Taking the screen projection content as an example, in the screen projection process, the application runs at a screen projection end, the screen projection end transmits running pictures of the application to the screen projection end in real time, if face recognition is needed in the application running process, but because the user is located at the screen projection end at the moment, face recognition cannot be carried out at the screen projection end, namely the screen projection end cannot acquire a face image of the user, and at the moment, the screen projection end sends a face recognition request to the screen projection end. And after the screen-projected end receives the face recognition request, starting a camera of the screen-projected end, and acquiring camera data acquired by the camera of the screen-projected end. The screen throwing end sends the camera data collected by the local end camera to the screen throwing end, so that the screen throwing end can acquire the camera data sent by the screen throwing end.

Furthermore, the screen projection end can encode the data of the camera based on the H.264 standard and then send the encoded data to the screen projection end, and the screen projection end decodes the received data based on the H.264 standard to obtain the data of the camera. Among them, H.264, also part tenth of MPEG-4, is a highly compressed digital Video codec standard proposed by the Joint Video Team (JVT, Joint Video Team) composed of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG) jointly.

Step S20, replacing the data collected by the camera of the screen projection end with the camera data;

in this embodiment, because the application runs at the screen projection end, when the application needs to perform face recognition, the camera at the screen projection end can be started and face recognition can be performed based on the data acquired by the camera at the screen projection end. However, due to the screen projection scene, the user is located at the screen projection end, and therefore, even if the camera at the screen projection end is started, the camera at the screen projection end cannot acquire the face image of the user. The camera data sent by the screen projection end is obtained in step S10, and the data collected by the camera of the screen projection end may be replaced by the camera data directly, for example, the data collected by the camera of the screen projection end is discarded at the screen projection end, and the camera data sent by the screen projection end is marked as the data collected by the camera of the screen projection end.

Further, in an embodiment, considering that data collected by the camera at the screen projection end is invalid, the camera at the screen projection end may be controlled not to be started when the application needs to perform face recognition.

And step S30, sending the camera data to an application program of a screen projection end, so that the application program can perform face recognition based on the camera data.

In this embodiment, the data collected by the camera at the screen projection end is replaced with the camera data based on step S20, that is, the application program in the screen projection end that needs to use the camera data uses the camera data sent by the screen projection end at this time. After the camera data are sent to the application program of the screen projection end, the application program can perform face recognition based on the camera data.

In the embodiment, the camera data sent by the screen projection end is obtained; replacing data collected by a camera at a screen projection end with the camera data; and sending the camera data to an application program of a screen projection end so that the application program can perform face recognition based on the camera data. Through this embodiment, when throwing the screen to the application cloud, throw the application of screen end and carry out face identification through acquireing the camera data that is thrown screen end and send, guaranteed throwing the normal clear of screen end application to guaranteed that the cloud throws the screen and can normally go on.

Further, in an embodiment of the remote face recognition method of the present invention, step S10 includes:

In this embodiment, the screen-projected end is taken as a computer, and the screen-projected end is taken as a mobile phone. After the computer acquires the original camera data acquired by the local camera, considering that the data format of the original camera data may not be supported by the mobile phone, format conversion needs to be performed on the original camera data to obtain the camera data with the data format supported by the screen projection end, and then the camera data is sent to the mobile phone.

Further, in an embodiment of the remote face recognition method of the present invention, step S20 includes:

In this embodiment, the screen projecting end performs hook modification on the camera frame layer of the home terminal, that is, modifies the source of the data of the camera obtained by the application program in the home terminal, where the original source is the data obtained by the camera of the home terminal, and after the hook modification, modifies the source into the data of the camera sent by the screen projecting end obtained by the screen projecting end, that is, the data acquired by the camera of the screen projecting end is replaced by the data of the camera.

Further, in an embodiment of the remote face recognition method of the present invention, step S30 includes:

In this embodiment, there may be a plurality of application programs running at the screen projection end, and in the cloud screen projection process, for the plurality of application programs, only the application program to be screen-projected needs to use the camera data sent by the screen projection end, so that only the camera data sent by the screen projection end is sent to the application program to be screen-projected in the screen projection end. Specifically, when the screen projection end performs hook modification on the camera frame layer of the local end, only the source of the camera data obtained by the application program projected on the screen projection end is modified.

Further, the screen projection end transmits camera data to the screen projection end in a frame unit based on a preset protocol, and a protocol header format of the preset protocol is used for representing the size of each frame of data.

In this embodiment, the screen-projected end transmits the camera data to the screen-projected end in units of frames based on a preset protocol, that is, one frame of image is sent each time, where a protocol header format of the preset protocol is used to indicate a size of each frame of data, and the screen-projected end can convert the number of bytes to be read according to the size of each frame of data. Therefore, the data of the camera can be transmitted to the screen projection end, and the screen projection end acquires the data of the camera according to the protocol head.
