遠(yuǎn)距離智能虹膜身份驗(yàn)證系統(tǒng)

        本設(shè)計(jì)提出的遠(yuǎn)距離智能虹膜采集及識別系統(tǒng)，可以在一個(gè)超過120°的較大工作范圍內(nèi)，遠(yuǎn)距離全智能地跟蹤用戶，自動(dòng)地采集虹膜圖像并進(jìn)行識別。工作距離達(dá)到1-2 米，彌補(bǔ)了傳統(tǒng)虹膜識別系統(tǒng)圖像采集距離短、需要用戶主動(dòng)協(xié)助的缺陷，無需用戶主動(dòng)協(xié)助，給用戶提供了一種輕松便捷的使用體驗(yàn)。

        系統(tǒng)架構(gòu)于酷睿雙核處理器開發(fā)平臺，充分利用了“嵌入之星”開發(fā)板的硬件資源，集語音提示、觸摸控制、無線通信、遠(yuǎn)程數(shù)據(jù)庫于一體，具備智能化、人性化的細(xì)節(jié)設(shè)計(jì)，靈活實(shí)用。系統(tǒng)采用Direct show 圖形顯示接口，應(yīng)用了基于聯(lián)合圖像分析的人眼定位和基于Gabor 濾波的虹膜識別算法，并通過Intel 性能包IPP 優(yōu)化和OpenMP 線程優(yōu)化，效率高，速度快，實(shí)時(shí)性強(qiáng)。整個(gè)系統(tǒng)性能優(yōu)越，成本低廉，可應(yīng)用于安防、反恐領(lǐng)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.
