Problems solved by technology

The traditional teaching analysis method is to conduct manual analysis by watching videos. This method is time-consuming and laborious, and also has subjective uncertainty. Therefore, it has gradually been eliminated in the context of smart campuses and smart education. It is a computer-automated analysis method, among which video analysis is the most widely applicable method

Abstract

The invention discloses a classroom teacher behavior obtaining method and device based on video analysis and a medium, and relates to the technical field of intelligent teaching, and the method comprises the steps: extracting a frame of image in a video stream, and further extracting a region of interest from the image; Carrying out teacher target detection on the image extracted from the region of interest to obtain a teacher target region; Determining a teacher behavior state according to the position of the center point of the teacher target area; Returning to the execution step to count teacher behaviors in class time; The method is based on a classroom recording and playing system. an intelligent analysis function is added to the class video of the teacher; According to the system andthe method, the class behavior information of teachers can be detected, the behavior states of walking teaching, standing teaching, platform leaving teaching, platform entering teaching and the likeof the teachers can be analyzed, the states are counted and analyzed, and the class characteristics of the teachers are mined, so that the teachers can objectively and self-know the class conditions of themselves, and the teaching quality is improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent teaching, in particular to a method, device and medium for acquiring classroom teacher behavior based on video analysis. Background technique [0002] At present, education recording and broadcasting and on-demand systems have been gradually popularized in campuses, reducing the imbalance in the level of education between urban and rural areas. However, these recorded and broadcast videos can only be provided for users to watch, without intelligent analysis of the videos, the information utilization rate is not high, and part of the available resources are lost. Therefore, intelligent analysis of recorded classroom videos is a future development trend and an important link in the implementation of smart campuses. [0003] There are many analysis contents in teaching analysis, among which classroom teacher behavior analysis is a key content of classroom teaching analysis. Through the ...
