The Goal Line Technology… A revolution in the world of football to see if the ball has really crossed the goal line. This system was developed by the German company GoalControl. Seven high speed cameras connected by optical fiber to enable the exact position of the ball at the cage. The computer instantly removes image all elements other than the ball to render a 3D model of the trajectory in the end zone. The GoalControl-4D technology boasts a precision 5 mm above the specifications defined by FIFA. The soccer referee is immediately informed. A watch attached to the system vibrates and displays « Goal » when a goal is scored. France will remain in the history of the worldCup in Brazil after the first goal allowed by this technology on the goal line. It was June 15, 2014 in Porto Alegre. A shot from Karim Benzema who hit the post before returning to the guard just above the line… In the end, Goal-line technology validates the goal for Honduras against his camp.
