摘要
设计了一款基于嵌入式技术的自动指纹识别系统(AFIS),系统的硬件采用TCS316指纹识别模块和基于S3C2440 ARM9处理器的嵌入式mini2440 ARM平台,基于上述硬件开发了自动指纹识别软件,软件设计基于嵌入式Linux操作系统,采用模块化编程。所设计的指纹识别系统实现了指纹录入、搜索、比对、删除及指纹库清空等功能,并结合在考勤方面的应用,设计了基于Linux的QT触摸屏应用界面。实验结果表明系统的硬件和软件都能较好的工作,达到了预期的目的。
An embedded automatic fingerprint identification system （AFIS） is designed. The hardware of system uses TCS316 fingerprint identification module and mini2440 ARM platform based on S3C2440 processor, the software is based on the above hardware and embedded Linux operating system using the module programming method. All function of loading, searching, matching, deleting fingerprint and emptying fingerprints of the whole system is tested separately. The result demonstrates that both the hardware and soft of system work well and expected purpose is achieved.
