Abstract

The learner's behavior can reflect the learner's learning state to a certain extent. Traditional learner behavior re-cognition methods have problems such as low real-time performance and low accuracy. Aiming at the above problems, this paper proposed a learner behavior recognition method based on improved OpenPose. This method was considered from the point of view of human bone joints. Firstly, it removed the Gaussian noise in the image through Gaussian filtering, and then detected the target student position in the image through the target detection algorithm integrated into the attention mechanism, and then extracted human bone joint point coordinates from the detected image through the improved OpenPose model, and finally used the ST-SVM to classify the acquired joint point coordinates to quickly and accurately identify the learner's behavior state. The experimental results show that the method can quickly and accurately recognize the student's actions, the accuracy rate is over 99%, and the fps is over 20. Compared with the original model, the fps is improved by 50%.
