人脸签到系统的设计与实现
摘要
考试是选拔人才的重要手段，要求的是绝对的公平和公正。对考核的公平造成了很大的影响。因此，如何有效地提高考生的身份识别率，确保考试的公正，就显得尤为重要。在当前的考试系统中，大部分考场都是通过人工对身份证和准考证进行识别的，这样做会造成人工成本高，识别错误的可能性也大。在此基础上，本文针对生物辨识技术中的人脸识别技术，设计了一种便携式考场签到装置和系统，并将其与人脸识别、电子识别相结合，实现了一种综合认证的方法。本装置识别率高，速度快，体积小，可离线应用。
考试现场登记系统的主要作用是通过对考生的电子身份信息与其面部特征进行双重匹配，从而有效地防止了考试中的代考。考虑到人脸识别算法的复杂程度和现场签到设备的便携需求，本文在对人脸识别算法进行深入研究的基础上，进行了软件和硬件的合理设计，在资源有限的嵌入式环境中，实现了对人脸的检测和识别，并与 RFID技术相结合，实现了对考生身份的综合验证，达到了考场签到和防止替考的目的。本文通过对考务工作的具体要求，如考场签到、信息管理等，对考试系统进行了详细的分析。整体上，从考生信息采集、身份识别、考试信息管理三个角度，对考试系统的运行过程进行了分析，并对重点考场识别装置进行了详细的设计与实施。首先对各种不同的人脸识别算法进行了比较和分析，选择了基于改进的 FaceNet模型的人脸识别算法，在资源有限的情况下进行人脸识别，从而达到了对识别率和响应速度的要求。在此基础上，根据考场标识设备的识别率、响应速度、成本和体积等具体要求，开发了一套安全可靠的嵌入式软件和硬件系统。
最后，完成了身份验证装置的设计与实现，并进行了仿真实验。实验结果证明，该系统可以完成多种身份验证，识别率、响应速度等各项指标都达到了设计要求，具有很好的应用前景。

Abstract
Examination is an important means of selecting talents, which requires absolute fairness and justice. It has a great impact on the fairness of assessment. Therefore, how to effectively improve the examinee's identification rate and ensure the fairness of the examination is particularly important. In the current examination system, most examination halls identify ID cards and examination admission cards manually, which will result in high labor costs and high possibility of identification errors. On this basis, this paper designs a portable examination room sign in device and system for face recognition technology in biometrics, and combines it with face recognition and electronic recognition to achieve a comprehensive authentication method. The device has the advantages of high recognition rate, fast speed, small volume and offline application.
The main function of the on-site examination registration system is to effectively prevent the substitute examination in the examination by double matching the electronic identity information of the examinee with its facial features. Considering the complexity of face recognition algorithm and the portability requirements of on-site check-in equipment, this paper conducts a reasonable design of software and hardware based on the in-depth study of face recognition algorithm. In an embedded environment with limited resources, it realizes face detection and recognition, and combines with RFID technology to achieve a comprehensive verification of the examinee's identity, so as to achieve the purpose of check-in and prevent substitute examination. This paper makes a detailed analysis of the examination system through the specific requirements of the examination work, such as examination room sign in, information management, etc. On the whole, the operation process of the examination system is analyzed from three perspectives of examinee information collection, identity recognition and examination information management, and the identification device of key examination places is designed and implemented in detail. First, various face recognition algorithms are compared and analyzed, and a face recognition algorithm based on the improved FaceNet model is selected to perform face recognition with limited resources, thus meeting the requirements for recognition rate and response speed. On this basis, a set of safe and reliable embedded software and hardware system is developed according to the specific requirements of identification rate, response speed, cost and volume of examination room identification equipment.
Finally, the design and implementation of the authentication device is completed, and a simulation experiment is carried out. The experimental results show that the system can complete a variety of identity verification, recognition rate, response speed and other indicators have met the design requirements, and has a good application prospect.
