Patent attributes
A sports simulation system (100) comprises at least two imaging devices (128) capturing images of a projectile tracking region disposed in front of a display surface (124) from different vantages to detect a launched projectile traveling through the projectile tracking region towards the display surface; a projectile spin sensing unit (105) capturing images of a region at least partially overlapping with the projectile tracking region, each captured image comprising a projectile trail representing a travel path of the projectile when a projectile is present in the region during image capture; and at least one processing stage (104) receiving data from the imaging devices (128) and the projectile spin sensing unit (105) and determining the three-dimensional positions, velocity, acceleration and spin of a detected launched projectile traveling through the projectile tracking region, the three-dimensional positions, velocity, acceleration and spin being used by the at least one processing stage to calculate a trajectory of the launched projectile into a presented sports scene.
