针对传统门禁系统“认物不认人”的使用缺陷和安全隐患，本文设计了一款基于人脸识别技术的门禁管 理系统。其搭建的嵌入式开发平台选用S3C2440B 为微处理器，WinCE6.0 为操作系统。同时系统移植了OpenCV 视觉 函数库，调用AdaBoost 及PCA 算法的相关库函数完成人脸图像的检测与识别并最终将识别结果作用于门锁的开关控 制。相比于传统的门禁管理系统，本设计更为安全方便、自动化程度更高，同时也给用户带来更为轻松便捷的使用感受。

Aiming to the defects and potential safety hazard of traditional entrance guard system , this paper designs an entrance guard management system based on the technology of face recognition. The embedded development platform choses S3C2440B as microprocessors, WInCE6.0 as an operating system. At the same time, the system transplants OpenCV, invokes the AdaBoost and functions of PCA algorithm, in order to complete face image detection and face recognition. Finally, the recognition result will acts on the door lock switch control. Compared to the traditional entrance guard management system, the design is safer and more automatic, which brings easier and more convenient experience to users.
