Controlled Study on Video-Based Capture and Virtualization of Body Motion in Athletic Sports

For the complexity of the body movements in the videos of the athletic sports, the new video-based capture method is proposed, and it overcomes the errors when the body parts are obscured and the body joints do not meet the physical restraint system of the body. Compared with the other body motion capture techniques, it is low in cost, targeted and easy to implement. In terms of the design and modification of the virtual men, the paper puts forward the self-similar method based on the motion itself and the joint curve adjustment method based on the normal distribution.
