Living body detection method and system based on binocular depth information

The invention provides a living body detection method and system based on binocular depth information, and belongs to the technical field of image processing, and the method specifically comprises the steps: carrying out the determination of the living body recognition probability of a user through the facial features, background features and definition of a facial image of the user, historical non-living body recognition times, current living body recognition times, a living body recognition result and a living body recognition probability are determined based on a user identity, a living body comprehensive recognition probability is determined, a secondary living body recognition probability is determined through detection interval time, and depth information features of a face image of a user are obtained through at least two camera devices. And a living body identification result is output in combination with the living body comprehensive identification probability and the secondary living body identifica
