Face living body recognition method based on video sequence

The invention relates to a face living body recognition method based on a video sequence, and the method comprises the steps: obtaining a video clip, and obtaining N key frames related to a face; image background information is obtained based on the key frame, if the consistency of the image background information is lower than a threshold Th1, the corresponding face in the current image is a living body, and recognition is ended, otherwise, face features are obtained based on the key frame, and if the consistency of the face features is lower than a threshold Th2, the corresponding face in the current image is a living body, and recognition is ended. Otherwise, the corresponding face in the current image is a non-living body. In combination with an artificial intelligence algorithm, living body judgment on the captured pedestrian video sequence is realized on the basis of an existing pedestrian peccancy detection scheme, so that a pedestrian peccancy record is prevented from being triggered by an advertiseme
