通过人脸识别技术限制重复投票的电子投票系统的设计

摘要

将人脸识别技术应用于电子投票系统中,限制重复投票行为.首先分析了该电子投票系统的结构,给出了人脸识别技术在限制重复投票行为中的应用场景.针对电子投票系统对人脸识别算法的需求以及投票人图像采集背景简单和光照变化较小的特点,分析了适用于本系统的基于AdaBoost的人脸检测方法以及基于特征脸的人脸识别方法,给出了通过OpenCV实现的基于人脸识别方法的身份认证子系统的设计流程,并介绍了基本投票子系统各模块的功能.最后对身份认证子系统的性能进行了分析.%Face recognition technology is applied in the electronic voting system to restrict repetitious voting operations. The structure of the electronic voting system is firstly analyzed and then the application scenario of face recognition technology in restricting repetitious voting is introduced. For the electronic voting system's requirements on face recognition algorithm and the characteristics that the background of the voters' images is simple and the illumination condition varies little, this paper analyzes face detection method based on AdaBoost and face recognition method based on Eigenface respectively, both of which meet the requirements of this system, presents the design flow of the identity recognition sub-system based on face recognition with OpenCV, and describes functions of each model of the basic voting sub-system briefly. Finally, performance analysis of the identify recognition sub-system is shown in this paper.
