ABSTRACT:
An apparatus and method to compute the trajectory of a moving object by remote, non-interfering sensors. The particular application computes the trajectory of a pitched baseball throughout its flight, including the ball's trajectory as it passes in the vicinity of a three-dimensional strike zone. The apparatus includes two pairs of video cameras, an alignment mechanism, video-storage means, a digitizer, a computer, output devices, and an operator's console. This apparatus is required to identify the ball, compute its position in three dimensions as a function of time, compute ball speed trajectory, and present the output via computer graphics to present the viewer with essentially any desired view of the pitch.
