Hao Meng · 2011
A kind of access control system based on iris recognition is designed.This system is composed of an iris image capture device,an access control circuit board and a PC.A semitransparent mirror is set before camera for helping users judge position by themselves.Infrared and visible light inside device is used to irradiate iris and promote image quality.Access control circuit is designed by use of Single-Chip Microcomputer 89S52,which functions such as man-machine correlation,communication with PC and electromagnetic lock control can be realized.Iris recognition algorithms are processed by PC.This image capture device have small size and good capture quality.The access control system achieved has good performance.
