While referee mistakes are an integral part of football, it can lead to a lot of controversy in high-stakes games like World Cup matches. Because to err is human, technologies are developed to assist referees and help them make the right decisions.
Officially introduced in 2012, ‘Goal Line Technology’ helps to avoid arguments over whether the ball has crossed the goal line. It was launched after much controversy during the 2010 World Cup and Euro 2012.
This technology has recently been bolstered by the introduction of VAR, which allows judges to review the action from multiple angles and in slow motion to make a decision. Introduced in 2017, the reception is quite mixed, but technology allows fairer arbitration.
offside help
Offsides are situations that are sometimes difficult to assess (especially during a quick counter-attack) depending on the position of the referee or the assistant referees. Without using VAR to help them, the new system will be introduced in Qatar during the 2022 World Cup.
In concrete terms, the sensor integrated into the balloon transmits its position to the ground at a frequency of 500 Hz (i.e. 500 times per second). 12 overhead cameras will track up to 29 points from the player’s body and transmit a warning to referees who will assess whether offside is appropriate in the VAR room and alert colleagues on the pitch.
This treatment only takes a few seconds, but the final decision is left to the discretion of the judges. Applied technology onlyArbitration assistance, no automated arbitration Pierluigi Collina, chairman of the FIFA referees committee, reassures.
Developed using machine learning and three years of research, the system will also generate synthetic images that can be broadcast on television and giant stadium screens to be as transparent as possible for the public.
