The progress of education has made higher education workers realize the importance of educational reform, and the teaching of music performing arts has an important role in cultivating students’ music, performance and many other skills. In this paper, under the guidance of augmented reality key technology, the music performance scene image is calibrated in the pixel domain, and the image is further preprocessed using real-time human body keying principle based on HSV to meet the requirements of three-dimensional scene construction. Combined with the principle of three-dimensional reality fusion, double-sided camera and related software, the virtual scene of music performance is created. In view of the current situation of music performance teaching in colleges and universities, by integrating the music performance virtual scene into the traditional teaching mode, an interactive teaching mode based on augmented reality technology is designed, and the mode is verified and analyzed. After the intervention of the teaching mode in this paper, the teaching effect (P=0.005<0.05), participation (P=0.004<0.05), and positivity (P=0.008<0.05) show significant differences, while there is no significant difference in the traditional teaching mode, which indicates that the addition of the music performance virtual scene in the traditional teaching mode is more favorable to the improvement of the level of students' music performance.
