Problems solved by technology

[0003] In recent years, people's research on face recognition methods is in the development stage. At present, most of the face recognition is realized by combining visible light with near-infrared technology, but the recognition degree and safety factor of this method are not high.
On the other hand, the current 3D face recognition algorithm is relatively complicated, the system overhead is large, and the efficiency is not high
It makes it difficult for the current mainstream face recognition algorithm to achieve a balance between recognition efficiency, accuracy and system cost

Abstract

The invention provides a face recognition method and system combining 3D structured light, infrared light and visible light. A 3D structured light depth living body algorithm is adopted; by processingthe object depth information acquired by the 3D sensor, combining the visible light and the near-infrared sensor, and through a depth living body and visible light near-infrared algorithm, the safetyof face recognition is improved, the system overhead can be reduced, and the face recognition efficiency and accuracy are improved to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a face recognition method and system combining 3D structured light, infrared light and visible light. Background technique [0002] Face recognition is a popular research topic in computer pattern recognition and biometric authentication technology, which is widely used in entertainment, information security, law enforcement and surveillance. Generally speaking, face recognition mainly refers to computer technology for identifying human identity through human facial visual information in digital images or video images. Compared with fingerprint recognition and palmprint recognition, face recognition has the characteristics of convenience, speed and acceptance. [0003] In recent years, people's research on face recognition methods is in the development stage. At present, most face recognition is realized by combining visible light with near-infrared technology, but the ...
