The present invention provides a sensing device and a sensing method used for a virtual golf simulation device, wherein: even though an inexpensive camera with relatively low resolution and low speed is used, an obtained image is analyzed such that physical characteristic information, such as speed, direction, and a height angle or the like of a moving ball, is extracted in a relatively exact manner; and particularly, since the motion trajectory of a golf club is calculated in a relatively exact manner through said obtained image, ball spin is estimated in a relatively accurate manner and the estimated result is reflected in golf simulation, thereby forming a virtual golf simulation device with high accuracy and high reliability at a low cost, and further, the reality of virtual golf is further improved. |
