| description | The invention relates to the technical field of education and teaching, in particular to a teaching evaluation method and system based on AI classroom behavior recognition. The method comprises the following steps: collecting and preprocessing a teaching video, and respectively extracting video streams and voices of the teaching video to be processed; carrying out target detection based on a YOLO target detection algorithm, obtaining all target objects in the teaching video, and determining the positions and types of the target objects; carrying out attitude analysis on all target objects in the teaching video by adopting a single camera based on an attitude evaluation algorithm, extracting features through relative positions of key points, analyzing actions of the target objects, and carrying out behavior recognition; and performing action recognition by adopting a trained full-connection neural network, and performing behavior statistics on the target object according to an S-T algorithm to obtain an analys |
