System and method for standardized speed-evaluation of athletes
View Patent ↗A system and method for standardized speed-evaluation of athletes that uses a photoelectric sensor configuration to create a laser grid by which an athlete's position over time will be monitored during, and analyzed after a test session. The photoelectric laser sensors are configured to establish the athlete's starting and stopping time along with the integrated synchronized video motion sensing. The athlete's motion is processed and transmitted by both a high-speed motion camera and a secondary test camera installed at specified distances. The secondary camera streams video data to the remote viewers in a wide-angle perspective. The athlete's movement is captured on video and transmitted to remote viewers via internet-streaming.
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.
2. The method claimed in claim 1 , wherein one of said first and second cameras is a high-speed motion camera, and wherein said capturing and transmitting said movements of said person begins upon said initial movement of said person.
3. The method claimed in claim 1 , wherein data of said movements is transferred to a remote server by video streaming and accessible via an Internet Protocol address.
4. The method claimed in claim 1 , wherein said starting position is a down-hand surface separation.
5. A system for measuring an athlete's performance comprising:
a laser beam emitter configured to create a laser beam;
a laser beam receiver configured to receive the laser beam created by the laser beam emitter;
a plurality of reflective agents positioned between said laser beam emitter and said laser beam receiver to form a laser beam grid;
a first camera configured to record a background with no foreground image for measuring against a silhouette of the athlete to determine a true start;
a second camera configured to operate in conjunction with the first camera and laser beam grid to determine the movement of the athlete over a specified range;
a distance sensor for measuring the distance between predetermined locations.
