Development of Posture Evaluation System for Yoga Support

Abstract

The population is increasing to learn yoga as an easy exercise. In particular, online yoga using the video call app is attracting attention as a yoga class that you can enjoy even at home. However, attending a yoga class has the problem that time is limited. Another problem is that it is difficult to receive direct guidance from the instructor due to the large number of people. In this study, we propose a system that evaluates yoga poses using skeletal estimation. In the proposed system, OpenPose, which is a skeleton estimation technology, is made three-dimensional by inputting a video from three viewpoints. In addition, a more accurate three-dimensional skeleton is generated by performing coordinate interpolation[1] using the preceding and following frames at each joint point.
