基于人脸识别的门禁系统设计与实现

面部识别技术具有人脸信息实时持有、无需记忆或携带、非接触方式采集的特点。基于人脸识别的门禁系统以Samsung S3C6410嵌入式开发板为硬件平台，采用普通摄像头作为人脸图像采集设备，7寸LCD液晶显示触摸屏作为输入，由开发板加载的GPIO控制口及电子门锁组成。软件以嵌入式Linux为操作系统，设计并优化人脸识别算法，减少光照对识别的干扰，通过人脸库训练算法和人脸识别算法的软件运行，实现了人脸识别门禁系统的控制功能。本系统适用于近距离人脸识别，实行人员注册登记，具有多次使用的安防功能，具有非接触性、数据易采集、处理器功耗少、节省电能、成本低廉、便于安装、性能稳定的特点。

The Design and Implementation Entrance Guard System Based on Face Recognition

Facial recognition technology has the characteristics of real-time, no need to remember or to carry, non-contact collection in Biometric. The entrance guard system takes ARM11 processor as the hardware platform, using ordinary camera as facial image capture device, 7-inch touch-screen LCD display as an input and Electronic door locks as executing components by the onboard GPIO port control. The software takes embedded Linux as operating system to design and optimize facial recognition algorithm, reducing the light interference on the recognition. It realizes the control function of facial recognition system by running face database training algorithm and recognition algorithrm This system applies for facial recognition at close range to perform person registration. The function has many features of contactless, easy to collect, less power consumption, energy saving, low cost, easy to install and stable.
