Abstract

Racket game variants like Frescobol, Matkot, etc. are quite popular in many countries with beaches all over the world. In Greece the name of this newly born sport is Beach-Racket and it was recognized as an official sport in 2014. Key steps in its evolution were the introduction of a high-tech score measuring system, mobiXeyes, developed by Mobics S.A., a spin-off company of University of Athens. In this work we describe the basic rules of Beach-Racket and the technology adopted for fulfilling the requirements imposed by the sport. The system is based on two high frame rate cameras and implements a stereoscopic method to calculate the speed of a ball in every hit. Apart from this, it offers a GUI interface for setup, player and category management, calculation of statistics etc. The system in general can calculate the 3D position and the speed of a fast moving object and could be used also in a wide range of relevant sports with none or minor modifications.
