The Aspire Dome Stadium in Doha, Qatar
Qatar 2022 will be the first FIFA men’s World Cup to use semi-automated offside technology as part of a wider innovation plan at the tournament.
FIFA says the new system will offer “a support tool for the video match officials and the on-field officials to help them make faster, more accurate and more reproducible offside decisions on the biggest stage of all”.
The tech was tested at the 2021 FIFA Arab Cup and 2021 FIFA Club World Cup ahead of being rolled out later this year.
Off-pitch officials will receive potential onside/offside alerts, with decisions evaluated away from the action before being communicated to the on-pitch referee to make a final decision.
Fans will also be shown how and why decisions are made via 3D animations on screen inside the stadiums with television viewers provided with an explanation.
The technology is more complex than current VAR and provides more ‘eyes’ on the action to give referees greater help.
Twelve dedicated tracking cameras — mounted in the stadium roof — will track the ball in play, and up to 29 data points will be placed on each player, 50 times per second, calculating their exact position on the pitch.
Those data points will map each relevant point on a player’s body, which can be considered active, to create a full picture of an offside call.
Alongside this, extra cameras will pinpoint player positions, and moving images of their bodies, while the new World Cup match ball will also play a role.
Each Al Rihla Official World Cup match ball will have a sensor placed inside it to send data to the video operation room 500 times per second to accurately assess the point the ball is struck.
Information on the selected kick point from the in-ball sensor, together with data points from cameras, provides an instant picture of the offside scenario to the officials in the video team and allows for a faster decision to be made.
