Abstract
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.
Claims17
A sensing device used in a virtual golf simulation apparatus, comprising:
- at least one capturing means for sequentially acquiring images of a predetermined capturing range within which hitting is performed;
- a grabber for collecting and storing the images from the at least one capturing means;
- a shot detector for processing the images received from the grabber to sense whether hitting preparation has been completed and whether hitting has been performed by a user;
- and
- an image processing means for processing an image of a ball hit by the user, when the shot detector senses that the hitting has been performed, to extract information on physical properties of the moving ball.
(canceled)
A sensing method for virtual golf simulation, comprising:
- sequentially acquiring images of a predetermined capturing range within which hitting is performed;
- receiving and storing the sequentially acquired images;
- processing the stored images to sense whether hitting preparation has been completed;
- sensing whether hitting has been performed by a user upon sensing that the hitting preparation has been completed;
- and
- processing an image of a ball hit by the user, upon sensing that the hitting has been performed, to extract information on physical properties of the moving ball.
A sensing method for virtual golf simulation, comprising:
- storing a ball template preset as a reference image of a ball;
- sequentially acquiring images of a predetermined capturing range within which hitting is performed;
- extracting a ball candidate from the acquired images and comparing the ball candidate with the ball template to find and recognize a ball;
- determining whether the recognized ball satisfies a predetermined condition to sense whether hitting preparation has been completed;
- setting a region of a predetermined size around coordinates of the acquired images at which the ball is located as a region of interest, upon determining that the hitting preparation has been completed, and comparing the image present in the region of interest with a half template preset as substantially half of the ball template to determine whether the ball is present in the region of interest, thereby sensing whether hitting has been performed;
- and
- processing an image of a ball hit by a user, upon sensing that the hitting has been performed, to extract information on physical properties of the moving ball.
