摘　　要：充分利用人体指纹识别技术安全、可靠、便捷等优点,利用Cortex-M3为核心处理器实现门禁系统指纹识别,对指纹原始图像进行采集、处理及特征值提取,同时具有添加、删除指纹用户的数据管理功能;利用TFT液晶触摸屏作为显示和控制单元,实现人机交互功能.The access control system by using Cortex-M3 as the core processor to realize the fingerprint identifi- cation employes the advantages of human fingerprint technology such as safety, reliability, and convenience. It can collect and process the data and extract characteristic as well from the original fingerprint image. It can also perform the data management function such as adding and deleting fingerprint data in the database ; the TFT LCD touch screen is applied as display and control unit to realize the human-machine interaction.
