Abstract

The invention discloses a binocular stereo vision-based human face detection method, device and system. The method comprises a step of collecting human face video data according to a first pick-up head and a second pick-up head and determining whether or not a human face is in a preset common visual range of the first pick-up head and the second pick-up head; a step of generating a human face image depth map according to the human face video data if the human face is in the preset common visual range of the first pick-up head and the second pick-up head; a step of determining whether or not the human face image depth map forms a human face three-dimension structure diagram according to a preset three-dimension structure classification rule; and a step of indicating that the human face is a face of a living body if the human face image depth map forms the human face three-dimension structure diagram. With the binocular stereo vision-based human face detection method, device and system, the detection of the human face of the living body can be performed without depending on motion cooperation of a user, and a problem that the user may be not cooperative is solved.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a face detection method based on binocular stereo vision. Background technique [0002] With the gradual application of face recognition technology in the identity authentication neighborhood, counterfeit attacks (or copy attacks) pose a great threat to related face authentication systems, and also have adverse effects on the application of face authentication systems. . The live face detection technology is just a security technology to prevent attackers from using photos or videos to pretend to be other people to interact with computers. In many applications that rely on face for automatic authentication, in order to avoid computer being cheated by attackers and causing unnecessary losses, stable and reliable face detection is required. [0003] In the prior art, many human face liveness detection methods have been proposed by means of texture analysis, background an...
