基于虹膜识别技术的嵌入式信息采集系统的设计

针对传统身份识别的局限性，钥匙、卡片和身份证容易丢失和仿造，密码容易遗忘等问题，设计一款基于虹膜识别技术的嵌入式信息采集应用系统，实现对虹膜信息的采集、录入、注册，身份认证等功能。系统以嵌入式微处理器（advanced RISC machines，ARM）为核心设计了系统的硬件电路，采用虹膜传感器实现人体虹膜信息的采集，并以Windows CE为平台完成了应用软件的开发。可用于公司门禁系统、海关机场安检、刑事身份鉴别等。

Design of an embedded system of information acquisition based on iris identification technology

In view of the limitation of traditional identification, it is easy to lose and copy keys, cards or ID cards, and it is easy to forget the password, so we designed an embedded application system based on the iris identification technology, which can realize the functions of gathering, inputing, and registering the iris information and identification. The hardware circuit was designed by using advanced RISC machines(ARM) embedded microprocessor as the core.The iris sensor was used to gather the iris information, and the development of software was accomplished with the embedded OS Windows CE.The system can be used on the company entrance guard system, customs security of airport and criminal identification.
