Sensing method and sensing apparatus used in virtual golf simulation device

摘要

By despite using inexpensive camera with a relatively low speed and resolution and analyzing the image obtained, the present invention, physical property information speed of the ball in motion, such as the angle and height direction It can be extracted relatively accurately, in particular, through images so acquired, can be calculated relatively accurately the motion trajectory of a golf club, is reflected in the golf simulation estimated relatively accurately the spin of the ball on the basis thereof By doing that, which can not only be at a low cost and constitutes a virtual golf simulation device with reliability and greater accuracy, so as to improve the reality of the virtual golf, the virtual golf It is intended to provide a sensing method and sensing apparatus is used in the simulation device.
