Disclosed are a device for calculating flight information of a ball and a method of calculating flight information of a ball that are capable of rapidly calculating the motion parameters of a ball and a golf club using an infrared sensing type device or a camera sensing type device and very rapidly calculating spin information of the ball corresponding to the calculated motion parameters with high accuracy through a simple calculation with reference to database type information about the calculated motion parameters, and a computing-device-readable recording medium having the method recorded therein.

Device for calculating flight information of ball, method of calculating flight information of ball, and computing-device-readable recording medium having the method recorded therein

The present invention is not a method of directly calculating the rotational characteristics of a ball through frequency analysis of a received signal as in the prior arts, but a method of determining a final spin information by finding the spin information of the moving ball while approaching a ball trajectory predicted in terms of the trajectory of a moving ball using the position coordinate data of the ball to the trend data indicating the trend of the position coordinates of the moving ball. The present invention provides a method of finding the spin in terms of the trajectory of the moving ball, regardless of whether it is possible to check the frequency characteristics of the rotation of the ball from the signal reflected from the moving ball, and thus derives a fairly accurate and uniform spin calculation result.
