Design And Implementation Of Examination Room Sign-in System Based On Face Recognition

Examination is the main way to select talents,it requires absolute fairness,but fraud in the examination room seriously damages the fairness of the exam.Therefore,how to improve the accuracy of examination room identification and ensure the fairness of the examination has great research value.At present,in the examination room sign-in process,most examination rooms still use the method of manually comparing identity cards and admission tickets to determine the candidate's identity.This method has the problems of large labor costs and a high probability of error.Based on this,this article designs a set of portable examination room sign-in equipment and system,which uses the combined authentication technology of electronic identification and face recognition to identify the candidate's identity.The device has the characteristics of high recognition rate,fast speed,small size,and can be used offline.The core function of the examination room sign-in system is to double match the candidate's electronic identity information and face information to prevent test replacement behavior.In view of the complexity of face recognition algorithms and the portability requirements of on-site sign-in devices,through the study of face recognition algorithms,the software and hardware platforms are reasonably designed to implement face detection and recognition functions in an embedded environment with limited resources.At the same time,the RFID technology is used to realize the candidate's electronic identification,so as to complete the compound authentication of the candidate's identity,to achieve the purpose of signing in the examination room and preventing the replacement of the test.This article analyzes the specific needs of examination services such as examination room sign-in and information management,and designs the examination room sign-in system as a whole.It analyzes the system business process from three aspects: candidate information collection,candidate identification,and examination information management.The identification equipment was designed and implemented in detail.Firstly,various types of face recognition algorithms are compared and analyzed.Face recognition algorithms based on the optimized Face Net model are selected.Face recognition is implemented on mobile terminals with limited resources,which meets the sign-in system's requirements for recognition rate and response speed.Then,a reliable embedded software and hardware system was designed according to the specific requirements of the identification equipment of the examination room for identification rate,response speed,cost,and volume.Finally,the identity recognition device was designed and implemented,and the entire sign-in system was simulated and tested.Tests show that the system can implement the compound authentication function,and the recognition rate,response speed,and other indicators all meet the design goals,and have good practical value.
