<P>PROBLEM TO BE SOLVED: To provide a projectile tracking apparatus having a display surface on which a visually apparent three-dimensional sports scene is presented. <P>SOLUTION: The projectile tracking apparatus captures images of a projectile tracking region in order to detect a launched projectile traveling through the projectile tracking region towards the display surface. One processing is responsive to the data received from camera devices 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 three-dimensional sports scene. Updated image data are generated by the at least one processing stage that includes a simulation of the launched projectile into the 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 three-dimensional sports scene, including the simulation, on the display surface. <P>COPYRIGHT: (C)2007,JPO&INPIT |
