The present invention is related to a device and method for sensing motion of sphere moving on plane using single-camera, and device and method for sensing motion of golf ball moving on putting mat that a low-cost single-camera is used for sensing a sports sphere moving on a plane as a target object, and the sports sphere can be detected without a separate dedicated lighting and a space in which the sphere moves can be recognized, so it can be used regardless of location with a simple configuration, away from the limitation that the installation position of the camera must be fixed.

Device and method for sensing movement of sphere moving on plane surface using camera, and device and method for sensing golf ball moving on putting mat

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.
