Abstract

As the first classroom teaching mode with thousands of years of development history, it is still an irreplaceable teaching form now and in the foreseeable future. In this paper, the smart education laboratory built by our school is used, and the quantitative analysis of classroom attention teaching based on random cascade regression and PnP method is used to realize the visual display of learning attention. Using the quantitative analysis of facial expression recognition in classroom teaching based on FACS and KNN classification algorithm, using Gabor and ULBPHS feature fusion, after PCA + dimensionality reduction, the learning emotion judgment and output are realized. Using the quantitative analysis of teacher attention based on three-dimensional feature point coordinate transformation of face and viewpoint visualization, the intersection of the rays in the classroom coordinate system on the camera plane is calculated first, and then the mapping point coordinates of the intersection in the teacher’s coordinate system are calculated. Finally, the viewpoint visualization in classroom teaching is realized.
