Abstract
A system for training a pitcher to pitch a baseball includes a plurality of emitting body markers worn by the pitchers, a plurality of position detectors for measuring both the position of the emitting body markers and the position of the pitched baseball, a target, a processor and a display. The processor is coupled to the emitting body markers, the position detectors and the target. The pitcher pitches the baseball to the target. The display is coupled to the processor. Each position detector is a locating array which has at least one ultrasonic transmitter and at least three non-collinear ultrasonic receivers. The locating array is disposed in the path of flight of the pitched baseball and and is used to determine the speed and the trajectory of the pitched baseball. The position of the emitting body markers are measured either optically or ultrasonically over a period of time so as to enable the analysis of the pitcher's body mechanics. The body mechanics analysis is also applicable to the golf, tennis, other sports and medical diagnostics.
