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.

Abrégé

A sports simulation system includes a projectile tracking apparatus having a display surface on which a visually apparent three-dimensional sports scene is presented. The projectile tracking apparatus captures images of a projectile tracking region disposed in front of the display surface to detect a launched projectile traveling through the projectile tracking region towards the display surface. A projectile launch area sensing unit captures images of the projectile launch area. At least one processing stage communicates with the projectile tracking apparatus and the projectile launch area sensing unit and is responsive to the data received therefrom to determine the three-dimensional positions, velocity, acceleration and spin of a detected projectile traveling through the projectile tracking region. The determined three-dimensional positions, velocity, acceleration and spin are used by the at least one processing stage to calculate a trajectory of the launched projectile into the visually apparent three-dimensional sports scene. Updated image data is generated by the at least one processing stage that includes a simulation of the launched projectile into the visually apparent three-dimensional sports scene following the calculated trajectory. A projection unit coupled to the at least one processing stage receives the image data from the at least one processing stage and presents the visually apparent three-dimensional sports scene, including the simulation, on the display surface.
