Abstract(in English) | This paper shows similarity evaluation methods for detecting the motion difference between individuals to teach sports form. First, we capture time series data of joint positions by using Kinect (which is a motion sensing devices by Microsoft). Motion duration of sports varies from a person to a person. So we use the DP matching to make two motion lengths equal. We calculate correlation coefficients of joints quaternions every one second between quaternions. In the proposed method, we calculate vectors connecting joints (direction vector) at each frame from the time warped data, and evaluate them by using Euclidean distance at the same frame. We have conducted experiments in Karatedo motions and obtained that the proposed method could detect detailed difference between motions. |
