Access control system based on iris recognition and method for iris recognition by utilizing system

Abstract

The invention discloses an access control system based on iris recognition. The system comprises a cabinet and a lock at an access control part, wherein a first chamber unit and a second chamber unit are arranged on the cabinet side by side; a wide field of view camera and a distance sensor are arranged in the first chamber unit, and an iris recognition device is arranged in the second chamber unit and fixedly arranged in the second chamber unit through a rotary pan-tilt; the iris recognition device comprises a casing with an infrared light filter plate arranged on a front panel, and a central processing unit and an iris collector are arranged in the casing; the lock, the wide field of vie camera, the distance sensor, the rotary pan-tilt and the iris collector are all electrically connected with the central processing unit. The iris collector can track irises of people in real time, the iris recognition function can be realized when a user walks, accordingly, a door has been opened when the user walks in front of the door, and the user experience is good.

Description

technical field [0001] The invention relates to an access control system, in particular to an iris identification-based access control system and an iris identification method using the system. Background technique [0002] As a product of modern life, access control has entered tens of thousands of families. With the continuous development of society, people's requirements for the security, stability, and networking of access control systems continue to increase. Users urgently need a Higher performance, smarter products. At present, most of the access control on the market uses magnetic cards, IC cards, radio frequency cards, etc. to identify the identity of the entrant, which cannot solve the problem of other people punching the card instead of the person. [0003] With the development of biometric technology, traditional access control is gradually replaced by biometric access control. Compared with traditional IC card access control, biometric access control is safer, ...

Problems solved by technology

[0005] The second technical problem to be solved by the present invention is to provide a method for using the system for iris recognition. This method solves the problem that the existing iris access control system has a relatively short recognition distance and requires users to stop in front of the iris recognition device. The recognition process can only be completed by repeatedly adjusting the position, the user experience is poor, and the recognition efficiency is low. The real-time tracking of the iris of the moving person by the iris collector is realized, and the user can perform iris recognition while moving.
