Virtual golf simulation apparatus and sensing device and method used for the same

摘要

Disclosed are a virtual golf simulation apparatus in which any position of a hitting mat, on which a user places a ball, is recognized to easily and accurately find the position of the ball even when a slope is realized with respect to a swing plate and the swing plate is sloped at a predetermined angle, and it is possible to accurately sense when hitting has been performed by the user using a relatively inexpensive sensing device without an additional trigger sensor, thereby reducing costs and improving sensing accuracy and reliability, and a sensing device and method used for the same.

主权项

1. A sensing device of a virtual golf simulation apparatus, comprising:
at least one camera sequentially acquiring images of a predetermined capturing range within which hitting is performed; and a sensing processor including: a grabber collecting and storing the images via the at least one camera; a shot detector processing the images received from the grabber to sense whether hitting preparation has been completed and whether hitting has been performed by a user, the shot detector,
setting a hitting region of a predetermined size, at which hitting is performed by the user, from the images received via the grabber and being configured to recognize a ball by extracting at least one ball candidate from the set hitting region and finding the ball from the at least one ball candidate,wherein a half template is preset and stored in the shot detector as a reference image of a portion of the ball, andcomparing a portion of the ball candidate with the half template and calculating a degree of similarity between the portion of the ball candidate and the half template to recognize the ball candidate as the ball when the calculated degree of similarity is equal to or greater than a predetermined reference value; and an image processor processing a ball-hit image by the user, when the shot detector senses that the hitting has been performed, to extract information on physical properties of a moving ball.
