Abstract

The invention discloses a living human face recognition method and a device, which belongs to the field of human face recognition. The method comprises steps: a human face image is acquired through two configured cameras; through the two cameras, depth information of an organ point in the human face image is acquired, and the depth information and a distance between the corresponding organ point to the end have negative correlation; a human face gesture of the human face image is determined; and according to the depth information of the organ point in the human face image and the human face gesture, whether the human face image is a living human face is judged. Through configuring the two cameras, the depth information of the organ point in the human face image and the human face gesture are acquired via the two cameras, whether the human face image is a living human face is judged according to the acquired depth information and the human face gesture, a user does not need to make a facial behavior in a cooperation mode, demands on the user are reduced, and the problem that living human face recognition fails as the facial behavior of the user is not obvious can be avoided.

Description

technical field [0001] The present disclosure relates to the field of face recognition, in particular to a living body face recognition method and device. Background technique [0002] With the development of biometric identification technology, face recognition technology has been widely used in the field of identity verification. Through face recognition, the current user can be authenticated to improve security. However, in practical applications, there may be criminals who use other people's face photos to counterfeit their own faces for identity verification. Therefore, in order to improve security, it is necessary to perform biometric recognition on human faces. [0003] Since the live face can be changed but the forged face cannot be changed, when the liveness detection is performed on the face, some facial action commands can be issued to the detected user, such as blinking command, mouth opening command, etc., and the user is required to cooperate to make correspon...
