Description: 本项目名称是：基于FPGA的指纹识别模块设计。
主要内容为：本模块采用xilinx公司的Spartan 3E系列XC3S500E
型FPGA作为核心控制芯片，通过富士通公司的MFS300滑动式电容指纹传感器对指纹图象进行提取，然后对提取的指纹图像进行灰度滤波、图像增强、二值化、二值去噪、细化等预处理，得到清晰的指纹图象，再从清晰的指纹图象中提取指纹特征点，存入外部FLASH作为建档模板。指纹比对时，采用同样的方法获得清晰的指纹图像，建立比对模板，然后将比对模板与建档模板利用点模式匹配算法进行比对，得出比对结果。该模块利用嵌入式软核实现系统的管理，利用硬件实现指纹识别，保证了系统功能的完整性与识别的正确性。该识别模块可用于门禁、考勤、安检、保险箱柜等很多方面，也可和计算机等设备联机使用，满足各个方面的不同需求，因此它的设计具有很广泛的应用前景和市场价值。
