基于嵌入式Linux的指纹识别系统设计

Design of Fingerprint Recognition System Based on Embedded Linux

为了解决现有嵌入式指纹识别系统的不足,提出了一种基于嵌入式Linux的指纹识别系统的实现方法,具体介绍了系统软件设计思路,其中主要包括软件平台的搭建以及指纹识别系统应用软件的开发。内容有指纹模块的各个功能函数、串口通信程序、指纹BMP图像生成程序、用户数据库管理程序、系统交互界面程序等等。由于系统基于嵌入式Linux,不依赖于特定的处理器,具有很强的移植性,可以根据特定应用场合对系统进行二次开发和移植。系统给用户提供了良好的操作界面,并且实现了一个用户可以在数据库中同时注册多个指纹的功能。经过仿真和验证,系统能够满足应用的要求。

In order to solve the existing deficiency of embedded fingerprint identification system,this paper puts forward a kind of fingerprint identification system realization method which is based on embedded Linux operating system,and it concretely introduces the system software design idea,which mainly includes the software platform building process and the fingerprint recognition system application software development.The content involves the functional functions of fingerprint module,serial ports communication procedures,fingerprint BMP image generator,user database management procedure,system operation interface procedures,and so on.The system based on the embedded Linux,not rely on a particular processor,so it has the very strong portability.
