Abstract
A capture-ball-based on-ball point distribution method, and a motion-posture recognition method, system, and apparatus are provided. The on-ball point distribution method is used for optical motion capture, and includes dividing a surface of a ball into a plurality of sub-regions, and distributing reflective marking points in the plurality of sub-regions such that a distribution of distance values between any two reflective marking points is concentrated. The reflective marking points are used for the optical motion capture of the ball. According to the on-ball point distribution method and the motion-posture recognition method, system, and apparatus, misrecognition caused by matching errors of the reflective marking points and increased coordinate errors of the spherical center can be effectively avoided. As such, the recognition degree of the capture ball in the system is improved.
