The Research And Realization Of Online Examination System Based On The B/S And Face Recognition Technology

An examination is an important way for teachers to know about the students' acquisition of knowledge.At present,most of the graduation exams in Xiangtan Technician College are paper-based,with a heavy workload and cumbersome work of marking papers.This traditional examination method not only consumes a lot of labor and time,as well as inefficiency and highly rated errors.In order to solve the problems and difficulties above,the online examination system of Xiangtan Technician College combines face recognition technology,and triple recognition of password,fingerprint and face recognition can better be carried out in the system than before.The passive inspection can be changed into active real-name authentication before taking the examination,so as to achieve the purpose of supervising students' real name.The core of the examination system is the function of automatic test paper generation.In the examinations of technical colleges,there are many subjective questions in the operation steps.In order to realize the subjective questions into the system and complete the systematic objective scoring,the online examination system suitable for the college is deeply studied according to the requirements of each department of the college.According to the functional requirements of the system,I conducted the following research work:1.Focus on investigating the test requirements of all departments in the university,establish the requirements document,and determine the key and difficult points to be solved at present.2.Requirements analysis and general design of the overall framework of the online examination system were conducted,and different modules were divided according to functions.Functions and connections of each module were introduced in detail.The system structure,function module and database are designed in detail by object-oriented method3.Focus on the design of the function of automatic test paper generation,and realize the moderate difficulty in examinations.A variety of objective questions and subjective questions are integrated into the volume,and use keywords and key phrases to objectively score the subjective questions.4.The real-name registration examination module can realize the attendance of the invigilator and the identity authentication of the student during th e examination through the triple authentication of password login,fingerprint authentication and facial recognition authentication,reduce the workload of invigilator and fundamentally prevent surrogate exam-takers.Used the method of software test on the above research work on the system testing,on-line examination smart group volume loading on the basis of the function of face recognition,simplify the invigilation process improve the efficiency of supervision,minimize their stead examinations.However,compared with some commercial software,the system still has a certain gap in stability and mutual friendliness...
