FIFA has confirmed it will use semi-automated offside technology during the 2022 Qatar World Cup.
The new technology will use 12 specialised tracking cameras mounted underneath the roof of the stadium to track the ball and up to 29 data points of each individual player, 50 times per second, calculating their exact position on the pitch.
The 29 collected data points are said to include all limbs and extremities that are relevant for making offside calls.
The ball itself will also play an important role in tracking an offside through the sensor which is located at the centre. It sends ball data to the video operation room 500 times per second, meaning it gives a very accurate detection of the kick point.
By combining the two, the video assistant officials will get an alert to determine whether an attacker was in an offside position. They will then manually validate the decision by checking the automatically selected kick point and the automatically created offside line, which is based on the calculated positions of the players’ limbs.
After a decision is made, a 3D animation will be projected onto the big screen inside the stadium to allow spectators to view the outcome.
FIFA president Gianni Infantino said: “Semi-automated offside technology is an evolution of the VAR systems that have been implemented across the world.
“This technology is the culmination of three years of dedicated research and testing to provide the very best for the teams, players and fans who will be heading to Qatar later this year, and FIFA is proud of this work, as we look forward to the world seeing the benefits of semi-automated offside technology at the FIFA World Cup 2022.”
Pierluigi Collina, chairman of the FIFA referees committee, added: “We expect that semi-automated offside technology can take us a step further.
“We are aware that sometimes the process to check a possible offside takes too long, especially when the offside incident is very tight.
“This is where semi-automated offside technology comes in – to offer faster and more accurate decisions.”
FIFA tried and tested the use of VAR (Video Action Replay) for the first time during the 2018 World Cup in Russia.
The 2022 Qatar World Cup begins on November 21 and ends on December 18.
