Research And Application Of Line-of-Sight Detection In Examination Monitoring System

It is a long and complicated process that the traditional examination method,which consists of the teacher's paper,the student's paper answer,the teacher's manual reading and the artificial examination of the four steps.Computer and Internet technology continues to deep into all aspects of people's lives today,online exam system simplifies the traditional examination process,breaking the geographical and time constraints.The online exam reduces the time and effort spent by the teacher on the exam,but improves the quality of the exam while facing a lot of security issues.With the examination of cheating more and more diversified and concealment,as well as the increase in the number of subjects,only rely on teacher supervision has been unable to fully meet the requirements.Therefore,an effective way to ensure that online exams are fair and prevent cheating is very important.In this paper,the use of pc computer camera,the line of sight detection technology applied to the test monitoring,research and development of a new network of test monitoring system,provides a low-cost,efficient way to ensure fair examination,To prevent cheating.The main contents of this paper are as follows:1.The paper introduces the key technology of line-of-sight detection based on pc camera:face detection,human eye recognition and extraction,SVM algorithm and so on.2.designed based on the line of sight examination of the overall monitoring system monitoring system.The composition and function of the system are analyzed.Finally,the key logic processing and workflow of the system are described in detail.3.After analyzing and designing the online examination and monitoring system,the technical realization of the key function module of the examination and monitoring system based on the line of sight detection is described in detail,including the image collection and uploading of the browser-side candidates,the screen monitoring of the candidates,the browser-side face Detection,server-side line of sight detection and candidates exception handling.Using computer vision library to achieve line of sight detection,in order to improve the efficiency and quality of development.4.the paper examines the workflow and core functions of the examination and monitoring system based on the line of sight examination,and analyzes the test results to verify that the system is running normally.
