Constructing a Guarantee System for Physical Education Teaching Reform and Innovation in the Digital Era

Abstract

In this paper, the world coordinate system transformation in virtual reality technology is utilized to obtain the gesture information for estimating human movement in the process of physical education, and the dynamic sampling light projection algorithm is used to match the gestures of human sports movements. The selection algorithm based on the Q statistic defines the virtual reality technology difference as the error trend of the existence of the difference obtained by each classifier for the new data sports students, and at the same time, combines with the VRT method to construct the VR sports teaching model. In the digital teaching of sports, digital sports teaching materials can be produced by motion editing and video synthesis, and statistical analysis methods can be used to study and analyze the teaching of sports in the digital era. The results show that the highest value recognized by the supervised training algorithm based on JPCD+SRD is 0.92, while the highest value recognized by this paper’s algorithm is 1, i.e., it shows that the effect obtained by this paper’s algorithm is higher than that of supervised training methods, which makes the effect of action recognition in virtual reality technology further improved. The average scores of sit-ups of girls in the control class and the experimental class were improved by 4.03 points and 11.4 points, respectively, compared with those before the experiment, i.e., the use of Internet tools to assist teaching has a significant promotion effect on the sit-up scores of girls. This study facilitates teachers to innovate teaching methods and promotes the process of digital teaching reform in physical education.
