Similarity analysis of motion based on motion capture technology

Abstract

This research has been successfully developed similarity analysis system of the human body motion from two kind of motions, the martial art actor motions comparing with reference motion capture data. This system used optical motion capture technology with 8 cameras. The system was able to show the calculation result of angle and angular velocity from every joints of human body motion. This system was able to performed 3D visualization of actor models and skeleton of reference data motion. The evaluation of the similarity motion was done by calculating the joint angle and angular velocity of the motions which is showed from the graphics of every joint with cosine similarity methods. The actor motion analysis in this research showed that average similarity level of joint angle has similarity value 0.816 and average angular velocity similarity 0.758.
