Research on Motion Capture Technology of Peking Opera Performing Arts and Its Practicality Exploration in Opera Physical Training

In this paper, we obtain the form data of famous Peking Opera performers through inertial motion capture technology to construct a standard form library. Sensors are placed in key parts of the body of Peking Opera performers to capture position information, and specific 3D data is obtained after a series of calculations. The long and short-term memory network is also used to solve the problem of form timing, and the captured form data of teachers and students are presented intuitively and visually, so as to study the application of motion capture technology in theatrical form training. Comparative analysis shows that compared with the other two algorithms, the accuracy of the method in this paper has a mean value of 93%. When completing the form exercise “Qiba”, the rate of change of the right knee angle was 0.56 for the student and 0.22 for the teacher. As a result, the teacher’s voice is more consistent. The teacher’s rotational acceleration of the spine is higher than that of the students in the “Shake by Flag” form, showing his/her greater strength. In the movement analysis of “Harrier Turn”, the teacher’s spine vertical angle is bigger.
