基于ARM—Linux指纹识别系统的设计

摘要

生物识别技术应用越来越广泛，指纹识别技术尤为突出。设计了以ARM9为核心的硬件平台。并进行了嵌入式Linux内核的移植，结合硬件特点，将优化后的指纹识别算法作为应用程序移植到软硬件平台。实验表明，系统运行稳定，算法效率和精确度较高，在嵌入式生物识别技术应用领域有一定的参考价值。%The application of biometric identification technology is more widely used by people, especially fingerprint identification technology. The following design base on ARM9 as the core of hardware platform, and an Linux kernel is embedded in it. Optimized algorithms of fingerprint identification are transplanted to software and hardware plaffowa combined with the hardware features. Experiments showed that the system is stable, the algorithm efficiency and the precision are higher. It is certain reference value in the embedded biometric identification technology.
