Abstract

The invention provides an online classroom atmosphere evaluation system and method. The evaluation system comprises a video stream collection module, a data stream processing module, an image analysismodule, a classroom attendance analysis module, a classroom atmosphere evaluation module, a classroom atmosphere scoring module and a display module; . The invention collects classroom video stream data through a camera, and the captured video is captured frame by frame to obtain images; all the faces images are segmented and numbered sequentially, at the same time, the eigenvalues are assigned to the faces with the corresponding numbers, and then face recognition and facial expression recognition are carried out according to the number, so as to identify the number, emotion and movement posture of students in the video stream data; the score 0 is given to the students lowering heads in the image and the score 1 is given to students having interaction; according to the emotional analysisstrategy of students listening to the teacher, the current student listening student score is obtained and finally comprehensive evaluation of the classroom atmosphere score is obtained. The inventioncan evaluate the classroom quality on-line and in real time, and can effectively improve the evaluation effect.

Description

technical field [0001] The invention relates to the field of education technology, in particular to an online classroom atmosphere evaluation system and method. Background technique [0002] With the popularization of university education and the emergence of various entertainment facilities, some situations that are not conducive to teaching generally appear in the classroom of college students, such as students playing mobile phones in class, listening to music with headphones, dazed, sleeping, etc. This situation seriously affects classroom teaching. quality. Due to the low learning interest of the students, it is impossible to give timely feedback to the teachers about the problems in the teaching process, and some teachers are unable to teach the students more content that the students are interested in, resulting in poor classroom teaching atmosphere and poor classroom teaching quality. The decline was severe. Based on the above problems, in order to improve the qual...
