FIFA explains the 'semi-automatic offside technology' to be introduced at the 2022 World Cup


International Football Federation (FIFA) explains the ``Semi-automated offside technology'' used in the 2022 FIFA World Cup , which will be held in Qatar from November 21, 2022.

The World Cup introduced VAR technology for the first time in Russia 2018 and it was a huge success. In response, FIFA President Gianni Infantino declared that 'we will strive to maximize the use of technology and further strengthen our VAR technology.' As part of the enhancement of VAR, FIFA has been developing technology with Adidas and partner companies, and announced that it will adopt 'semi-automatic offside technology' at the 2022 FIFA World Cup. FIFA says this will allow pitch referees to make offside decisions faster and more accurately.

You can see what FIFA's 'semi-automatic offside technology' is like by watching videos published on YouTube and videos published on Twitter by Brian Swanson, Director of Media Relations of FIFA.

Offside is one of the most difficult soccer rules to interpret. According to the J League official, offside is a rule established to prevent players of the attacking team from ambushing within the field of the defending team in order to score. Or if a team-mate in an offside position interferes with the opponent or gets involved with the ball, it is a foul and an indirect free kick is awarded to the opposing team.'

The problem is that it is difficult to judge whether the player of this attacking team (white silhouette in the back of the screen) is in an offside position.

FIFA's 'semi-automatic offside technology' is to judge this more accurately using technology. Adidas'

Al Rifra , the official ball of the 2022 FIFA World Cup, has a built-in inertial measurement unit sensor (IMU), which is necessary to detect offside scenes that are difficult for human referees to judge. It provides important information. A sensor mounted on the ball sends the ball's position information to the video operation room 500 times per second.

And 12 dedicated tracking cameras mounted under the roof of the stadium will track 'ball position' and 'up to 29 data points about players' 50 times per second.

The 'up to 29 data points about the player' collected by the camera measure where the player's limbs are as follows.

'Semi-automatic offside technology' uses artificial intelligence (AI) to collect 'ball position information' collected by the IMU inside the ball and 'player position information and limb information' collected by dedicated tracking cameras installed in the stadium. Offside decision is made by analyzing using.

Every time an attacking team on the pitch receives the ball, the system automatically sends an offside decision to the operator in the video operations room. The operator of the video operation room checks the sent offside decision before it is conveyed to the referee on the pitch, verifying the system's decision with human eyes. This will allow offside decisions to be made quickly and accurately.

After the operator checks the offside judgment of the system, it is sent to the referee on the pitch, and after the final offside judgment is decided, a 3D animation to clearly show what the judgment was like is displayed by the dedicated tracking camera. It is generated based on collected data points about the player's limbs.

The 3D animation will be shown on the big screen on the pitch and on the official broadcast of the World Cup.

In addition, FIFA's semi-automatic offside technology has been successfully operated in many test events and has also been adopted in official FIFA tournaments such as the 2021 FIFA Arab Cup and FIFA Club World Cup 2021 .
