Human identification device used for face recognition system

Abstract

The invention relates to a human identification device used for a face recognition system, belonging to the technical field of face recognition. The human identification device comprises a left light source, a right light source, a camera and a computer; the left light source and the right light source are respectively arranged at the right front side and the left front side of a to-be-recognized person and used for lighting the face of the to-be-recognized person; and the computer is respectively connected with the left light source, the right light source and the camera. The human identification device provided by the invention identifies the to-be-recognized person and a paper photo and a display screen through utilizing the positive and negative faces formed by a manner that the head of the to-be-recognized person shields the side lighting, the identification accurate rate is high. Compared with the prior art, the identification device does not need the to-be-recognized person to do expression changes to match the recognition, and moreover, the device solves the defects that in the prior art, only the dynamic photos can be identified and the dynamic screen images cannot be identified, thus, the security and convenience of the face recognition system are greatly improved; and meanwhile, by adopting the technical scheme provided by the invention, the system is simple and reliable in structure, fast in identification speed and easy in implementation.

Description

technical field [0001] The invention relates to a real person identification device used in a face recognition system, belonging to the technical field of face recognition. Background technique [0002] Face recognition technology conducts identity identification by analyzing and comparing face biometric information. Compared with other biometric identification technologies, face recognition is a more direct, more convenient, more friendly, and more easily accepted non-invasive identity. recognition technology. With the wide application of the face recognition authentication system, there have been security incidents where illegal users use legitimate user photos to pass the system identity authentication. [0003] In order to identify a real person and a photo, some face recognition systems have added a real person identification function, which uses the user's facial expression changes (blink or smile) to identify whether it is a real person or a photo. This real person i...

Problems solved by technology

[0004] (1) It requires a lot of facial expressions and actions on the user's face, 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;

[0005] (2) When illegal users use tablets or laptops to play video images of legitimate users for identification, they can still pass system identity authentication
