The striker shoots the football, catching it with his laces. The ball seems goal-bound, but it hits the underneath of the top post and bounces off the ground. The striker screams with joy thinking he has scored. His teammates rush towards him; the crowd is in raptures. All that is needed is for the referee to check his watch and blow the whistle disallowing the goal. The scorer is shell-shocked. TV replays show that the referee got it spot on. How did he manage that in just a few seconds?
Goal Line Technology
Thanks to goal line technology, the referees can now make the correct decision when it comes to nail-biting goals where no one can determine the clear result. Ask the German team of 1966 and they will tell you how it feels to not have a goal that was legitimate. To eradicate such errors, FIFA introduced the new technology that took centre stage in the 2014 football World Cup in Brazil.
Goal Line Technology now continues to be used in club football such as the Premier League of England.
How does it work?
There are fourteen cameras placed around the rim of the host stadium of the match. Seven cameras are placed around each post. The cables from the cameras are wired to a computer.
The cameras track the ball as it nears the post, constantly feeding the computer with the data. The position of the ball is able to be precisely located in relation to the goal line. If the football crosses the line, a visual signal accompanied by a vibration is transmitted wirelessly to the referee’s watch with ‘Goal’ flashing on it. If the ball does not cross the line, no signal is sent to the referee. Goal Line Technology is that simple and easy to use.
