The company, called GoalControl, would install 14 cameras in each of the 12 World Cup stadiums that triangulate the motion of the ball with maximum precision: up to 500 images per second.
With that tracking, plus sensors on the goal line, GoalControl can instantly alert a referee when the ball crosses the line. There's no need to consult a replay booth or another official; the referee in charge merely looks at their smartwatch.
In other words, say "bye" to ghost goals in Brazil.
"The cameras are connected to a powerful image-processing computer system which tracks the movement of all objects on the pitch and filters out the players, referees and all disturbing objects," a GoalControl representative said.
If the system registers that the ball has crossed the goal line, it can send a vibration and a visual "GOAL" signal to referees' watches within a second.
GoalControl says the idea was developed by Dirk Broichhausen, a company founder, after he attended a soccer match in Germany in which there was a dispute over a goal. He began contacting technicians the next day.
