Access control method and system

Abstract

The invention discloses an access control method and system. The access control method and system can overcome the problems of poor reliability of face recognition and low overall work efficiency of conventional access control systems. The method comprises the following steps: detecting whether a moving object exists in the field angle range of a camera; snapshotting the moving object if the moving object is detected in the field angle range; receiving the input of identity characteristics; verifying the received identity characteristics if the input of the identity characteristics is receivedin a first predetermined time period starting from the moment when the snapshotting of the moving object begins and if a facial image meeting requirements is snapshot during the snapshotting of the moving object; and if verification is passed, controlling unlocking of the access control system, or otherwise, controlling locking of the access control system. The access control method provided by the invention is applicable to access control in access control systems needing verification of both the facial and identity characteristics of a passing person.

Description

technical field [0001] The invention relates to the field of security technology, in particular to an access control method and system. Background technique [0002] The access control system, also known as the access control system, is an intelligent management system that manages the access of personnel. The access control system integrates microcomputer automatic identification technology and modern security management measures. It involves many new technologies such as electronics, machinery, optics, computer technology, communication technology, and biotechnology. The access control system is an effective measure to solve the security management of the entrances and exits of important departments. It is suitable for various confidential departments, such as banks, hotels, computer rooms, armories, confidential rooms, offices, intelligent communities, factories, etc. [0003] The function of the access control system is to identify and confirm the identity of passers-by...

AI Technical Summary

Problems solved by technology

Due to the limited field of view of the camera and the difference in height of people, the camera may not be able to capture the faces of passers-by or only part of the faces may be captured, resulting in unsuccessful face detection.

[0005] In summary, the existing access control system needs to perform face detection after the passers-by swipe the card, that is to say, the passer-by needs to wait for the access control system to perform face detection after swiping the card, and the overall work efficiency of the access control system is not high; , due to the limited field of view of the camera and the difference in height of people, the camera may not be able to capture the faces of passers-by or only a part of the faces, resulting in unsuccessful face recognition, and the reliability of face recognition by the access control system is not high. high
