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.
