摘要：为实现基于嵌入式ARM的指纹识别门禁系统，采用了基于ARM9 的指纹识别门禁系统的软硬件设计，提出了指纹获取、指纹识别处理、指纹匹配等方法和相关算法。其中，硬件方面主要采用了三星公司的基于ARM920T内核的S3C2410A处理器和富士通公司的MBF200指纹传感器；软件设计包括了系统上电初始化、指纹识别处理、电控锁控制等部分以及Linux操作系统的移植和驱动的编写等。试验结果表明，该系统具有准确性高、识别快的优点，而且易于二次开发和功能扩展。

Abstract: To realizing fingerprint recognition access control system based on embedded ARM, the hardware and software design of fingerprint recognition access control system based on ARM9 was adopted. The measure and algorithm of fingerprint access, the process of fingerprint recognition, the match of fingerprint were brought forward. The main hardware was done which was S3C2410A processor based on ARM920T kernel of Samsung company and fingerprint sensor MBF200 of Fujitsu company. The software design was done, including of system electrification, the process of fingerprint recognition, the control of electronic control lock, the porting of operating systems for embedded systems and the preparation of device drivers etc.. The test results indicate that the system has high veracity, quick recognition speed, and it is easy to expand for the second time and its function.
Key words: ARM9; embedded Linux; access control system; fingerprint recognition; fingerprint sensor
