Entrance guard control method based on face recognition

Abstract

The invention discloses an entrance guard control method based on face recognition. The entrance guard control method comprises the three steps of image information collecting, data processing and entrance guard operating, wherein core data processing comprises the steps that analysis is performed on the basis of returned video images, face images are automatically captured, compared and matched with existing photos in a database, and the faces are recognized. Particularly, means such as a face detection optimization data structure, picture preprocessing and feature extracting are integrated in data processing, and therefore high-speed high-accuracy face verification and recognition are achieved. According to the entrance guard control method, the defect that traditional face monitor and recognition are poor in light change, attitude angle and time span stability is overcome, the detection rate larger than 99% and the recognition rate larger than 80% within 5 meters are achieved, and the utilization rate of traditional hardware resources is increased and the application range of network monitor is widened except that intelligent control over entrance guard and attendance is effectively achieved.

Description

technical field [0001] The invention relates to an access control method, in particular to an access control based on face recognition, which improves the security and ease of use of the access control, and belongs to the field of image data processing and application. Background technique [0002] Since the 911 terrorist attacks, people began to pay more attention to public security issues. In recent years, cities in the United States have added a large number of security monitoring equipment, and some large cities in China have also increased investment in public security monitoring. For example, the "Beijing Public Security Image Information System Management Measures" stipulates that Beijing's party and government agencies, hospitals, schools, kindergartens, etc., 5 categories, more than 40 units and areas should install public security image information systems; The Video System Management Regulations require that public security video systems be installed at the entra...
