Claim Text:
1. A sports simulation system comprising: a projectile tracking apparatus comprising a display surface on which a sports scene is presented, and at least one pair of camera devices aimed into a projectile tracking region from different vantages and having overlapping fields of view at least encompassing said projectile tracking region, said projectile tracking region extending from said display surface to a projectile launch area spaced in front of said display surface, said camera devices configured to capture images of said projectile tracking region, each camera device including processing capabilities and configured to process captured images to detect the presence of a launched projectile therein as the launched projectile travels from its launch position to its contact position with said display surface and then its rebound from said display surface; and at least one processing stage configured to receive data from the camera devices relating to images in which the launched projectile exists and determine three-dimensional positions, velocity, deceleration/acceleration and spin of the detected projectile traveling within said projectile tracking region, the spin being determined based on impact and rebound angles of the sports projectile with respect to the display surface, the three-dimensional positions, velocity, acceleration and spin being used by said at least one processing stage to calculate a trajectory of said launched projectile into said presented sports scene.
