Sthe semi-automatic offside is coming and everything seems to indicate that it is here to stay. In 2018 it was VAR and now the aim is to go further to ensure there is more fairness in football.

On November 22, it will be officially presented at the World Cup in Qatar and FIFA seem determined that it will continue to be used thereafter. Johannes HolzmüllerFIFA Deputy Chief Technology Officer, presented the project.

The system will help video refereeing teams and referees in the field to make faster, more accurate and more reliable decisions.

To improve communication with supporters and while the referee decides whether he is offside or not, the replay will be recreated on the stadium screens with 3D animation. It will be broadcast in the stadium and on television.

The semi-automatic offside will be official at the World Cup in Qatar.

The offside decision will be precise and reliable. All technology is created to help referees make decisions.

Twelve cameras installed under the roof of the stadium will capture the movements of the ball and up to 29 data points for each player. Fifty times per second, to calculate their exact positions on the field. The 29 datasets collected include the limbs and body parts that are taken into account to generate an offside.

The Adidas ball will include a sensor in the center, which will send data 500 times per second to the video room, allowing it to accurately detect the exact moment the ball is kicked.

There are two basic elements of the system, the ball catcher and the 12 cameras. They are the starting point of everything.

By mixing player limb and ball tracking data, and using artificial intelligence, the new technology sends an automatic notification to the video room whenever a ball is received by an attacker who was in an out position. -game when his teammate played the ball.

To corroborate his proposal before reporting it to the main referee, the video-refereeing team manually checks the exact moment of the shot provided by the data, as well as the offside line also created automatically and according to the positions of the player’s limbs calculated by the system. As it only takes a few seconds, the process allows for quicker and more accurate decisions.

Automatic alerts will reach the system operator within seconds of reading.

The whole process in 25 seconds

When there is a goal, an orange flag will automatically appear and that means the game is borderline offside and therefore everything clicks into place.

The video operators verify everything from this moment and inform the arbitration team immediately. The average of the whole operation before this system is 70 seconds and now it will be 25 seconds.

Once the decision has been made and communicated by the VAR to the referee, the previous process continues. A 3D reconstruction is made for fans in the stadium and on television. This is repeated and shows the exact position of the players and the ball. This process will be done when the decision has already been made by the referee.

The implementation of the technology in this system started in 2019. However, COVID delayed everything. In 2021 various tests were able to start, in particular during the Arabian Cup.

Pierluigi CollinaFIFA’s head of refereeing, defends the use of technology.

“There is talk of robot referees, it sounds good, but it’s not true” hill noticed.

“Referees on the pitch will continue to be decisive. Semi-automatic offside will only be used when an offside player touches the ball. If there is interference in play, it will be the referee’s decision. ‘arbitrator.

“In four or five it’s impossible, it will be in 25 or 20 seconds, which is very important. The goal is to be faster and more precise.”
