Carlo AncelottiReal Madrid coach criticized goal denied by him THERE IS To Marco Asensio After their ‘classic’ defeat against Barcelona. “We didn’t win because of an offside that we still doubt”Reassured the Italian coach about the lines drawn by the video arbitration system –Soto Grado of La Rioja commands-, a method in the constant debate that results in deciding the game and possibly LaLiga. But how to draw lines to detect an illegal position in Spanish football?

Two ways to draw VAR lines

As reported by Mr Asubío, an account specializing in arbitration in Spain Using the ‘Hawk-Eye’ systemAs in the main competitions organized by UEFA and FIFA. Two lines are used to detect offsides:

Grid – A two-dimensional line that can be quickly placed on the defensive line for clear offside decisions

Vanishing Point: these are the two lines positioned for the defender and the attacker.

The second assumption is the one used. To cancel Asensio’s goal that would make him 1-2 on the scoreboard Kessié’s goal almost made the situation 2-1 at the end of the match. In the ‘vanishing point’, ‘offside lines are drawn on the player’s body parts. offensive and defensive players that can be used to score goals“, as explained by the arbitration expert.

These parts of the body are the same for all players, including goalkeepers. Lines can also account for parts lifted off the ground, represented by a vertical line projected by 3D technology. The position of the crosshair is manual with a one pixel wide line. In this way, the VAR can accurately determine the exact position of the offside line and the relevant body part.

VAR technology ‘Hawk-Eye’ in La Liga

It should be noted that the two lines – the offensive player and the defender – are of different colors. “After drawing single-pixel lines in offside decisions, VAR places transmission lines where they are thicker and overlapthese will be considered offside (legal)”, explains the former referee of this national category. At this point it is important to know that what is shared with the audience is the final image confirming the offside decision.

As for the system used, the cameras of the ‘Hawk-Eye’ system used in each game are calibrated before that. There are numerous references to reach all parts of the body, regardless of the complexity of the players’ position. There are five cameras in LaLiga: the main camera, two cameras in the penalty area and two cameras on the goal line..

Key: when the passer touches the ball

Likewise, the ‘Hawk-Eye’ can also use transmission devices to determine the offensive player’s point of contact with the ball. The cameras of the audio-visual system work at 50 frames per second.. The point of contact with the ball is therefore one of those ‘frames’ that are picked up in that exact second.

This was another controversial point in the disallowed goal action given to Asensio. “From the arrival of the VAR, the image must be stopped at the first contact of the passer-by (in this case, Carvajal). not when the ball is out of his feet”, explains Mr. Asubío, which also sheds light on a question that can be confusing at first glance. Why don’t VAR lines sometimes look straight?

“A lot of it depends on the camera angle and perspective. Unless the stream camera is perfectly aligned with the last defender, the angle of the camera can make you look farther back or further aheadThe arbitration expert concludes about the method of VAR used in LaLiga that “what actually happens is in the drawn horizontal line”.
