Abstract

The invention discloses a double-camera recognition method for a human face of a living body, and the method comprises the steps: obtaining a black-and-white image and an infrared image through a black-and-white camera of the configured two cameras; obtaining a color image through a color camera; extracting two-dimensional state organ feature points through combining the human face parts in the black-and-white image and the infrared image with a feature extraction algorithm; forming a three-dimensional state organ feature points, recognizing the features of the human face of the living body through a human face recognition algorithm, and judging whether the human face image is the image of the human face of the living body or not. The invention also discloses a double-camera recognition device for the human face of the living body. The color image and the near infrared image are collected through the two cameras, and a background removing image is obtained through background difference calculation, i.e., the human face part. The feature points of an organ are extracted through the feature extraction algorithm, and the features of the human face of the living body are recognized through the human face feature recognition algorithm, so as to judge whether the human face image is the image of the human face of the living body or not. The method is high in reliability, is convenient and practical, and is low in implementation cost.

Description

technical field [0001] The invention relates to the technical field of living human face recognition, in particular to a living human face dual-camera recognition method and a recognition device. Background technique [0002] With the continuous updating of security technology, face recognition technology is more and more widely used in life. Especially in government departments, border customs and financial industries, it plays an irreplaceable role of intelligent security monitoring in security protection. Face recognition technology is becoming more and more mature, and commercial applications are becoming more and more extensive. However, faces are very easy to copy by means of photos, videos, etc. important threat. Over the years, live face detection technology has made some progress, but the safety, reliability and cost of the existing methods in practical application cannot be well balanced. [0003] The existing living face recognition technology mainly uses an or...
