Abstract:
1. A method for evaluating the performance of athletes, the method comprising the steps of: creating a laser grid by producing a laser beam with a laser beam emitter and using reflective agents to deflect said laser beam [into 90 degree angles] between the laser beam emitter and a laser beam receiver, to form a laser beam grid; capturing and transmitting movements of a person using a first camera for detecting an initial movement of said person and a second camera for monitoring movement over a specified range; measuring velocity of said person by detecting each time a beam in said laser beam grid is broken; measuring the speed at which said person travels between predetermined locations by using said laser beam grid and said first and second cameras; measuring the distance between said predetermined locations using a distance sensor; and modeling a background by recording with no foreground image, followed by using the person to create a foreground image to determine a true start of the person; wherein the true start is defined by the movement of said person within a predetermined time of a starting position.
