[0047] see figure 1 , figure 1 It is a schematic flowchart of a face recognition method based on video stream provided by the first embodiment of the present invention.
[0048] Described face recognition method based on video flow, comprises the steps:
[0049] S101. Collect the video stream to be identified;
[0050] S102. Use a template matching algorithm to perform face detection on each frame of the image in the video stream to be recognized, so as to filter out a face image to be recognized that contains at least one face, and extract a corresponding image from the face image to be recognized. key facial feature data;
[0051] S103. Perform similarity calculation according to the key face feature data and the reference feature data corresponding to each face model in the pre-built face image database to obtain a similarity result, and perform weighting processing on the similarity result to obtain Obtain the face recognition result corresponding to the maximum weight...

[0071] see Figure 4 , Figure 4 It is a schematic structural diagram of a face recognition system based on video stream provided by the second embodiment of the present invention.
[0072] The face recognition system based on the video stream includes a video acquisition device, a face feature extraction server, a face feature comparison server, a platform server and a client;
[0073] The video collection device is used to collect video streams to be identified, and transmit the video streams to be identified to the facial feature extraction server;
[0074] The face feature extraction server is configured to use a template matching algorithm to perform face detection on each frame of image in the video stream to be recognized, so as to filter out a face image to be recognized that contains at least one face, and from the Extracting corresponding facial feature data from the face image to be recognized, so as to transmit the facial feature data to the facial feature compar...
