Development of a real-time table tennis scoring system

This paper presents design and development of a computerized sensing and scoring system for table tennis games. The proposed system consists of piezo film sensors, data acquisition system, interface software and electronic score board. Piezo film sensors are employed to detect the ball on the line, edge and net. The table is equipped with piezo film sensors that provide the primary input to the system. These sensors were connected to the PC by data acquisition hardware. A referee interface software is developed for windows environment through which the referee interacts with the system. The software also generats output to drive an electronic score board. With the aid of the proposed system, the referee is expected to accurately detect high-speed balls on the line, edge and on the net.
