Research And Implement Of Intelligent S-T Teaching Analytical System Based On Computer Vision

S-T analysis method is a kind of objective quantitative analysis and evaluation method in classroom teaching,it can overcome the subjectivity of traditional classroom evaluation effectively by reflecting the teaching intuitively with graphical character.There are many software which are relevant to S-T analysis at present,but these software are implemented by means of artificial observation and recording to segment teaching behavior video of teachers and students,then obtaining the corresponding data.This way of obtaining data needs tedious work and a lot of human consumption.With the application of computer vision technology in the fields of video surveillance,identification,medical imaging detection,its characteristic such as intelligence,speed,wide application,has provided technical support in order to reduce human intervention.To deal with the problem of non-intelligent in this kind of video segmentation,this paper processes a video segmentation method of education video with teachers and students,users can obtain the S-T data sequence that corresponding teaching video effectively.This method is applied to the intelligent S-T teaching analysis system,which can automatically realize the coding of S-T data automation,and realize the intelligent support of the whole S-T analysis process.The main work of this paper is as follows:This paper proposed a video segmentation method of teaching behavior of teachers and students based on computer vision.This method combines the methods of face detection and similarity measure,which can effectively obtain S-T data sequence corresponding teaching video,it saved a lot of time of segmentation the teacher behaviors and students' behaviors compared to the traditional way and improved the efficiency and accuracy of video segmentation.In this paper,video segmentation method of teaching video with teachers and students that is based on computer vision was applied to S-T teaching analysis system,then designed and developed an intelligent S-T teaching analysis system which was based on computer vision.And the function and requirements of each function module of the system were analyzed in detail,the function modules of the system are designed on the basis of these analysis results.The experimental results of each module were demonstrated and the practical significance and value of the teaching analysis system are proved through the analysis of the experimental results.
