Vivo face identification device for face recognition system

Abstract

The invention relates to a vivo face identification device for a face recognition system and belongs to the face recognition technical field. The vivo face identification device for the face recognition system comprises a light source, a collecting lens, a lantern slide, a projection lens, a video camera and a computer, wherein the computer is respectively connected with the video camera and the light source, a light beam emitted from the light source irradiates on the lantern slide after passing through the collecting lens, and the projection lens projects an image of the lantern slide on an identified object. Compared with the prior art, the vivo face identification device for the face recognition system has the advantages of utilizing parallel lines which are projected out to identify the vivo faces, static graphic photos and dynamic screen images and being high in identification accuracy; not needing identified people to perform facial expression changes to cooperate with the identification, overcoming the defects that the prior art can only identify the static photos but can not identify the screen dynamic images and greatly improving the security and convenience of the face recognition system; being easy in structure, being reliable in work, being rapid in identification speed and being easy to implement.

Description

technical field [0001] The invention relates to a living body face identification device used in a face recognition system, in particular to a living body face identification device for identifying real people and photos through structured light illumination, and belongs to the technical field of face recognition. Background technique [0002] Face recognition technology identifies people's identities by analyzing and comparing facial biometric information. Compared with other biometric authentication technologies, face recognition is a non-invasive identification technology that is more direct, more convenient, more friendly, and easier to be accepted by people. With the widespread application of face recognition authentication systems, there have been security incidents that illegally use legitimate user photos to pass identity authentication. [0003] In order to identify real people and photos, some face recognition systems have added a live face recognition function, w...

Problems solved by technology

[0003] In order to identify real people and photos, some face recognition systems have added a living face identification function, which determines that the identified object is a live real person by changing the facial expression (blink or smile) of the identified person. This live face identification method exists The following disadvantages: need to do a lot of facial expressions and actions on the face of the person to be identified, the human-computer interaction method is not friendly, it is easy to make the user feel bored, and the algorithm is complicated, which reduces the speed of face recognition; moreover, if using a tablet or laptop computer , when playing video images of legal users, the identity authentication can still be passed, leading to security incidents
