Design and implementation of an embedded fingerprint identification system

为了克服基于PC平台的指纹识别系统体积较大、可移动性不佳、不便于携带等不足,对嵌入式技术实现的指纹识别系统进行研究。对指纹识别算法进行分析,从硬件与软件两个方面着手,使用S3C2410微处理器与MBF200指纹采集传感器为硬件核心,拓展必要的外部设备,设计完成指纹识别系统。经过实际测试,该指纹识别系统具有实时性好、识别准确率高的优点,体积轻便、便于移动,为同类产品的设计研究提供参考依据。

In order to overcome the insufficiency（large volume,poor mobility） of the fingerprint identification system based on PC platform,the fingerprint recognition system based on the embedded technology is researched,the fingerprint identification algorithm is analyzed,and the realization of the system is studied in the two aspects of hardware and software. The microprocessor S3C2410 and fingerprint sensor MBF200 are adopted as the hardware core to expand the necessary external devices. The fingerprint identification system was designed and completed. The actual testing shows that the fingerprint identification system based on S3C2410 possesses the advantages of good real-time performance,high recognition accuracy,small volume and light weight,and is easy to move. The research provided a reference for design of similar products.
