远距离智能虹膜身份验证系统

        本设计提出的远距离智能虹膜采集及识别系统，可以在一个超过120°的较大工作范围内，远距离全智能地跟踪用户，自动地采集虹膜图像并进行识别。工作距离达到1-2 米，弥补了传统虹膜识别系统图像采集距离短、需要用户主动协助的缺陷，无需用户主动协助，给用户提供了一种轻松便捷的使用体验。

        系统架构于酷睿双核处理器开发平台，充分利用了“嵌入之星”开发板的硬件资源，集语音提示、触摸控制、无线通信、远程数据库于一体，具备智能化、人性化的细节设计，灵活实用。系统采用Direct show 图形显示接口，应用了基于联合图像分析的人眼定位和基于Gabor 滤波的虹膜识别算法，并通过Intel 性能包IPP 优化和OpenMP 线程优化，效率高，速度快，实时性强。整个系统性能优越，成本低廉，可应用于安防、反恐领域。

This is an iris capture and recognition system integrated with face tracking, which can work in a remote distance up to 2 meters and wide-angle direction up to 120°. The system can intelligently and automatically capture and recognize an iris image. It makes up with the flaw of the traditional one which can only work in a short distance, and highly demands the user’s assistance. The system is based on Core Duo processor developing platform, embedded with Direct Show image displaying interface, applies an eye-locating algorithm based on union image analyzing technique and an iris recognition algorithm based on Gabor filter, making full use of the hardware resources of Embedded Star platform. In addition, we have developed a network database as well as a smart, friendly user interface. The design can be applied to security and antiterrorism fields.
