基于人脸识别的考勤系统设计

为了适应当今各企事业单位考勤业务需求，设计了一款嵌入式人脸识别考勤系统，并详细设计分析了该系统的实现方法。从硬件角度方面，利用ARM芯片的优势，对本文设计的嵌入式系统整体方案、硬件选择和开发环境的搭建等进行分析；另一方面，从软件的角度，依据系统功能进行设计，并提出一种基于PCA的人脸识别方法。最终通过系统性能测试，验证该方案的可行性。

Design of attendance system based on face recognition

In viewof the current business or school attendance requirements,design an embedded face recognition attendance system,and detailed design of the system.From the aspect of hardware,take advantage of ARM chip,designed in this paper,the embedded system overall scheme, hardware selection and development environment of the building are analyzed;at the same time,from the point of view of software,the functions of the system design,and proposes a face recognition method based on PCA. At last,the system performance is tested,and the feasibility of the scheme is verified.
