Intelligent physical education: an exploration of virtual reality applications in college martial arts courses

Abstract

Aiming at the existing sports and martial arts teaching system without VR simulation modeling, which leads to poor mastery of the training content of the trainees and high time delay of the system, we design the sports and martial arts teaching system based on VR virtual technology. Through VR technology to build a virtual training environment, realize the modeling of the three-dimensional scene of the VR system. First of all, design the system motion capture function module, according to the module to obtain the data of the students’ sports and martial arts action teaching, use the data to correct their errors in a timely manner, and complete the action estimation through the human body posture recognition technology to extract the key points in the course of the students’ three-dimensional coordinate information, to obtain the joint angle of the joints of the martial arts action joints trajectory and other multi-dimensional spatial and temporal data. Then, the recognized martial arts movements are compared and analyzed with the reference movements from the standard movement library. Finally, a multi-view collaborative layout is constructed to build a wushu action data visualization interface based on a multi-view layout, which intuitively displays the quantitative information of wushu actions and provides support for users to explore the information of wushu actions. At the first training, system 1 in this paper masters 10% more training contents than training system 2 based on pressure sensor technology and 17% more training contents than training system 3 based on mechanical vision technology. The time delay of System 1 is lower than that of System 2 and System 3 at every point during the gradual increase in the number of students. The test of student training content mastery and the system time delay test demonstrated that the system has strong practical performance.
