June
12, 2014 began the World Cup in Brazil, which will go down in history
as the world championship which was first used by the system Goal
Control-4D. The system can accurately determine whether the ball crossed the goal line and give a signal to the main judge. Goal
Control-4D works thanks to 14 high-speed cameras located around the
field, as well as seven cameras aimed at the goalkeeper's area. When crossing the ball to the goal line system in less than a second, sends a signal to the referee of the match. Football
community for many years led a lively debate, enter or not to enter
into the professional football system that could replace the judge in
determining the controversial moments goals. Proponents
of this innovation pointed to a huge number of egregious errors from
the referee, who often decide the fate of matches. Opponents offered not to undermine the authority of the arbitrators and not break the game dynamics.
But football authorities still had to introduce this innovation under public pressure. On the eve of matches her work showed reporters at the stadium
"Maracana" in Brazil, it has been successfully tested and installed on
all 12 stadiums that will play the World Cup.
Another
interesting technological solution was the use of the chief arbiter of
the match disappears within minutes spray to set a direct free kick and
the place where you want the wall. Before the judge suffered, pushing the wall in the allotted distance. Now this problem is solved. Will be immediately obvious, if someone came in defined boundaries. Attempts
to make cans with vanishing mixture were undertaken since the 1980s,
but only in 2002 the Argentine entrepreneur Pablo Silva has launched a
truly high-quality product.
