At the beginning of 2020, the new crown epidemic spread wildly, and most parts of the country were forced to press the pause button, which seriously affected the normal development of college sports work. In order to thoroughly implement the important instructions on the new crown pneumonia epidemic, the Ministry of Education issued the initiative of "suspending classes without stopping learning and teaching without stopping classes". Colleges and universities across the country responded one after another and started online physical education teaching and related work. This paper aims to discuss the application of computer vision and virtual reality technology in online teaching of public sports under the background of the new crown epidemic. In view of the current situation of online sports education, this paper analyzes the current virtual reality education ecology, and combines computer vision algorithms to propose a public sports online teaching method based on computer vision and virtual reality technology. The experimental results of this paper show that teaching in the form of online live broadcast, recorded broadcast, live broadcast + recorded broadcast can generally meet the students' exercise needs. However, there are still some physical education teachers with weak online teaching ability. There are about 364 students. About 63.64% of the students believe that their physical education teachers are not good at courseware production, and there is a dilemma of lack of teaching technology. The online public sports teaching mode can effectively meet the exercise needs of public sports students and improve their physical quality. There are 403 students, and about 70.45% of the students said that online public sports teaching can meet their exercise needs. Therefore, the full use of computer vision and virtual reality technology in online teaching can promote the application of digital teaching in schools and save educational resources for schools. It has created an innovative education model, improved the quality of school education, enhanced the experience of teachers and students, and attracted them to participate more.
