Iris imaging system design based on PC

The iris recognition technology gets rapid development with advantages such as high precision, non-invasive and etc. It is widely considered as one of the most promising biological certification technologies. The iris image acquisition is the key technology and gets more attention. This paper introduces a kind of iris imaging system based on PC. The system uses Micro Controller Unit (MCU) to control light source and ranging module and uses buzzer to indicate the distance between the user and the system. All these can improve the conveniency of the Man-machine interactive. Experiments show that this design method can get the high quality iris images, and enhances the usability of the system‥
