How it works goal-line technology adopted by FIFA

 Adopted the International Federation of Football two for the application of goal-line technology in the stadiums, a technique that, there has been much debated and rejected the International Federation (FIFA) heavily used before they finally succumb and give work permits to two out of three companies have technologies with the goal line.

And made three institutions of FIFA three techniques are technical Gul Reeve (GoalRef) and the Fraunhofer Technology and Technology appointed Falcon (Hawk-Eye), with techniques that are approved Gul countryside and eagle eye.

We review in Arabia Technology simplified how techniques work two selected by FIFA ...

- Jules Reeve

 

Gul Rural Technology is a technology that came out of the Institute of integrated communications in the city German Aarlngen, which rely on the ball to calculate the target or not.

German technique works simply by a slide show in the ball with a sensor (reader) that slide at the goal line for calculating target when passing the ball completely.

Who shall system GoalRef create a wireless signal like curtain light, so make magnetic fields low on goal and as soon as the ball has crossed (equipped machine microelectromechanical) line fully, are sensing change simple magnetic field, which allows to determine the exact location of the ball.

If score a goal, it is sent to alert hour match officials over a wireless signal during one second, as they appear on their watches with vibrating alert.

- Falcon Eye Technology

 

The British technical "Eagle Eye" is a technical months in the world of sports where it is used extensively in tennis in order to determine whether the ball went beyond the stadium or not.

The technique used high-precision cameras and very sensitive to the movement of the ball in order to identify and analyze the movement of the ball, a camera that will prove the target in order to determine if the ball over the entire goal line or not.

The installation of six to eight cameras characterized by the ability of high-speed imaging in different corners of the goal to determine the exact location of the ball.

The transmitted data obtained by the cameras to video program so that the system, using this data, the creation of a three-dimensional image of the path of the ball. The match officials are informed whether scoring or not during one second.

The Falcon Eye Technology has been tried in a friendly match between England and Belgium in Wembley Stadium, FIFA preserved results did not disclose them.
