Title:
DEVICE FOR SENSING MOVING BALL AND METHOD FOR CALCULATING MOVEMENT PARAMETERS FOR BALL BY USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/117503
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a device for sensing a moving ball and a method for calculating movement parameters for the ball by using the same, the device and the method determining final spin information by using, instead of a conventional method of directly calculating a rotating property of a ball through frequency analysis and the like of a received signal, a method of figuring out spin information of a ball while allowing a ball trajectory predicted from the point of trajectory of a moving ball to approach trend data indicating a trend for positional coordinates of the ball by using positional coordinate information of the ball, such that a highly accurate and uniform spin calculation result can be derived since spins are figured out from the point of the trajectory of the ball without depending on whether a frequency property for the rotation of the ball can be confirmed or the like from a signal reflected from the moving ball.
