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 ofthe 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.

Description

technical field [0001] The present invention relates to a sensing device for a moving ball and a method for calculating the motion parameters of the ball using it. A sensing device for analyzing a signal reflected by a moving ball and calculating a ball's motion parameter therefrom and a method for calculating a ball's motion parameter using the same. Background technique [0002] In the past, sports games using a ball, especially golf, have been performed by accurately sensing the physical characteristics of a ball moving by a golfer's strike and analyzing the shot using the sensed value or realizing it as an image. Suitable for attempts in the field of golf such as so-called screen golf. [0003] In particular, it is difficult to measure with a conventional camera sensor because the spin of a ball that is thrown out by hitting rotates extremely rapidly around an axis in a three-dimensional space. Currently, a lot of research and development is being carried out on a rada...
