According to the official website of the FIFA, the same technology that was used in last’s year’s clubs world cup in Marrakesh and Agadir will feature again for the FIFA Club World Cup 2014 in Morocco.
A statement from the FIFA said that “the German-based company [that developed the technology] has started to set up GoalControl-4D in Marrakech and Rabat, which will feature eight matches between 10-20 December culminating in the crowning of a champion at the Stade de Marrakech.”
As to give more insight on this technology, the leading Football body said that “GoalControl-4D is equipped with 14 high-speed cameras located around the pitch, with seven cameras focussing on each goalmouth. Using special detection software, the ball is filtered out from the image sequences and its real-time position is automatically calculated as X, Y and Z coordinates as well as speed, making it 4D. The indication of whether a goal has been scored is confirmed automatically within one second by a vibration and visual signal on each match official’s watch.”
