Modelling and implementation of an automatic table-tennis scoreboarding system

Increasing incomes and awards of games leads to better manage games for referees to prevent decision errors. Besides investments made by authorities to better train referees, it is becoming more and more necessary to automatize the game arbitration processes. For amateur games with no referee, there is also a need for an automation system to replace the referee. One of the popular games is table tennis played both at amateur and professional levels. In this study, a table-tennis automatic scoreboarding system is designed and implemented. The designed automation system uses a computer which receives the necessary signals from vibration sensors, makes right decisions according to the rules and controls the peripheral devices such as displays and speakers. This system assists referees to make better decisions in professional games and performs missions of referees in amateur games.
