摘要
设计了一种基于虹膜识别的门禁系统,该系统由虹膜采集装置、门控电路以及上位机构成。虹膜采集装置在摄像头前加装半透半反镜帮助使用者自主定位.装置内采用红外光和可见光配合照亮虹膜并提高图象质量。门控电路基于89S52单片机,具有人机交互、与上位机的通信和电磁锁控制等功能。上位机用来处理虹膜算法。该系统采集装置体积小,采集图像质量高。门控系统性能优良。
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.
