摘要
自动虹膜识别是一种非入侵式身份认证方法。目前的虹膜识别系统中图像采集系统的景深非常有限,获取清晰虹膜图像需要用户的密切配合,这阻碍了虹膜识别系统的广泛应用。本文提出基于波前编码系统的虹膜识别系统,极大地扩大了虹膜识别系统的景深,提高了虹膜识别系统使用的友好性。
Automated iris recognition is a method for noninvasive verification of identity.There is very shallow depth-of-field in current iris recognition systems.In order to acquire a clear image,it requires the user＇s cooperation.This obstacles the application of iris recognition system in a daily environment.In this paper,iris recognition system based on wavefront coded imaging system is proposed.It can greatly extend the depth-of-field of iris imaging.This facilitates the use of iris recognition system.
