A camera system is installed on the surface of each stadium and the information is transmitted to a video assistant who can then alert the referee.
FIFA, the governing body of world football, will use the Arab Cup in Qatar to experiment with semi-automatic intrusion detection using specialized cameras and a dedicated intrusion video assistant.
A camera system will be set up on the roof of each stadium and the information is transmitted to a video assistant who can then alert the referee.
According to Johannes Holzmueller, Director of Football Technology and Innovation at FIFA, “The limb tracking data extracted from the video will be sent to the operating rooms and the calculated offside line and detected kick point will be provided.”
“The replay operator then has the opportunity to display it immediately on VAR. In the Arab Football Cup, the VAR assistant referee at a dedicated offside station can immediately validate and confirm the information.”
However, the final decision will always be delegated to the officials in the VAR room and the referee.
If the results are positive, the system can be used in the 2022 World Cup in Qatar.
President of the FIFA Referees Committee Pierluigi Collina describe it Semi-automated intrusion technology as “the most important experiment to date”.
“Technology is very important and useful in both the pre-match preparation and the decision-making process during matches,” he said.
“In an offside incident, the decision is made after analyzing not only the players’ position but also their participation in the move. Technology – today or tomorrow – can draw a line but the assessment of interference in play or with the opponent remains in the hands of the referee.”
The Arab Cup, which takes place on four stadiums in Qatar, kicks off on Tuesday.
