Face recognition method and device, access control system, access control method and storage medium

Abstract

The invention provides a face recognition method, which comprises the steps: sequentially collecting two face images according to a time sequence; selecting one part of the human face as an original point, and respectively establishing coordinate systems for the two pictures; in the two symmetrical quadrants of the coordinate system, selecting at least one part of the human face; and judging whether the position of the part in one quadrant in the second picture relative to the position of the part in one quadrant in the first picture and the position of the corresponding part in the other quadrant in the second picture relative to the position of the corresponding part in the other quadrant in the first picture are simultaneously diffused or converged, if so, determining that the human face is a picture simulation human face, and otherwise, determining that the human face is a real human face. Under the condition that equipment is not increased, whether a human face is simulated by a picture is effectively judged.

Description

technical field [0001] The present invention relates to the field of face recognition and its application, in particular to a face recognition method, device, access control system, access control method and storage medium. Background technique [0002] With the research and continuous development of pattern recognition technology, its application in people's life is more and more extensive, and face recognition is one of the most important ones. Due to the immature development of face recognition technology, at present, the usual face recognition system cannot accurately determine whether the face in front is a natural face or a simulated face faked by a picture, especially when the registered face is not a natural person. existing face recognition systems cannot identify faces. There are also certain studies on the above-mentioned problems in the conventional technology. [0003] The invention patent application with the publication number CN101441710A discloses an imagi...

Problems solved by technology

[0004] The utility model patent with the application number 201020062476.5 discloses an optical structure of a polarization imaging detection system, which is characterized in that it can acquire four polarized radiation images of a scene at the same time, which solves the problems existing in the time series measurement method and the space matching measurement method, but the The optical structure of the system is complex, the volume is relatively large, and the requirements for the manufacturing precision of the optical components of the system are relatively high, and the requirements of compact structure, precise system and easy promotion and use cannot be achieved.

Therefore, in summary, the existing technology cannot achieve better technical effects in the face recognition system and in terms of face anti-counterfeiting performance.
