Abstract
Virtual image refers to the unreal image projected by projector, mobile phone, and other projection equipment. Through virtual images, we can explore some scenes that are difficult to observe directly with the naked eye or express fictional images in our minds. At present, the technology is widely used in construction industry, tourism industry, and medical system. At present, after the development of efficient physical education in China, schools generally do not pay attention to the specific application of virtual image technology in badminton teaching in colleges and universities in China. This paper analyzes the representative badminton events in China’s physical education, improves the traditional algorithm, optimizes the effective segmentation and recognition algorithm of virtual image technology in motion capture, combines the improved virtual image technology with virtual reality glasses, and compares the accuracy of the virtual image technology proposed in this paper with that of the traditional image technology. The accuracy of the virtual image technology proposed in this paper always remains the first. The practical application in badminton teaching in colleges and universities has achieved good results.
