Intelligent video teaching system based on cloud calculation model and expression information feedback

Abstract

The invention discloses an intelligent video teaching system based on a cloud calculation model and expression information feedback. The system consists of a data cloud, a student terminal and a teacher terminal, wherein the data cloud is separated into video data and a self-feedback intelligent control subsystem. The self-feedback intelligent control subsystem has the following specific steps of collecting video signal, and reading the video images of current student states; face detection, detecting whether faces exist in the current area; expression identification, classifying and identifying the feedback expressions of the students, and judging whether sleepy expression, puzzling expression and satisfying expression exist or not; feedback expression processing, generating different processing measures aiming at different feedback expression systems; and feedback information statistics and data report generation, centrally generating data reports for the feedback information. The intelligent video teaching system adopts the technical scheme that a user is taken as the center in the cloud calculation model, and an intelligent software platform is adopted. The intelligent video teaching system has the advantages that the cost is low, the availability is high, and easy expandability is realized.

Problems solved by technology

In fact, the high dropout rate is mostly due to the lack of communication between students and teachers and students when students are studying, resulting in a sense of loneliness, and some students have poor self-discipline in learning, which leads to such results

In addition, the slow feedback of academic performance leads to the reduction of students' interest in learning and the resulting frustration is also one of the reasons
