Problems solved by technology

Although the former can often achieve real-time effects, it does not consider the timing characteristics of the behavior, but only classifies the target state; although the latter can learn the timing characteristics of the position changes of the joint points during the movement, the recognition process of the joint points is A very computationally intensive process, and the accuracy cannot be guaranteed

Abstract

The disclosure provides a classroom behavior recognition method, device, equipment and storage medium, the method includes acquiring classroom video; performing target identification and tracking based on image frames in the classroom video to obtain target image stream; inputting the target image stream into the trained The recognition model is used to identify and obtain classroom behavior results. The trained recognition model includes: spatio-temporal feature network, which is used to extract features from the target image stream to obtain the spatio-temporal features of the target image stream; deep feature network, which is used to analyze spatio-temporal features Carry out learning to obtain deep features; classification network is used to classify deep features to obtain classroom behavior results. According to the present disclosure, the problem of many objects and occlusion in the classroom behavior recognition of the teaching classroom scene in practical application is solved. By enhancing the learning ability of time series features of classroom behaviors, it is possible to discover the changing rules of classroom behaviors in the time dimension, thereby improving the accuracy of students' classroom behavior recognition.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a classroom behavior recognition method, device, equipment and storage medium. Background technique [0002] With the continuous development of artificial intelligence, intelligence gradually enters all aspects of production and life. Concepts such as smart city, smart office, and smart medical care continue to emerge and develop rapidly. How to identify and analyze students' classroom behavior more efficiently has become a research hotspot in smart education. In traditional education, a teacher needs to teach dozens or hundreds of students. The traditional teaching experience: teaching students in accordance with their aptitude, entertaining and entertaining cannot be realized on such a large base. The energy of the teacher is limited and it is impossible to take care of so many students Students can only get feedback from a small number of students on the...
