Stupid prize on semi-automatic offside technology at Qatar 2022 World Cup

Tram Ho

Since its official appearance so far, VAR (Video Assistant Referee) referee technology has become an indispensable part of major football tournaments around the world, such as the Champion League and Europa League.

And now, 4 years after appearing at the 2018 World Cup held in Russia, VAR continues to appear at the World Cup being held in Qatar with a version that comes with a new step called: technology. semi-automatic offside detection. With a series of new equipment, organizers hope, this technology will change the face of matches by helping referees make decisions faster and more accurately.

Semi-automatic offside technology

The decision of offside situations on the field remains one of the most controversial issues in modern football. But with the advent of “semi-automatic offside” technology, the umpires can make the correct decision for each situation where this error occurs.

This technology uses 12 cameras mounted around the dome of the stadium to track the movements of the players and the ball on the field. This system will send data to the operating room 50 times per second to calculate the exact position of each player and the ball on the field. Not only position data, this camera system also collects 29 data points on the player’s body, including the position of the limbs as well as the head to determine if there is an offside position.

Al Rihla, the official ball for the Qatar 2022 World Cup, also contains another component that helps determine offside situations more accurately thanks to the inertial measurement sensor (IMU) inside the ball. Placed in the center of the Al Rihla ball, the sensor sends data back to the operating room 500 times per second to accurately detect the point of impact.

By combining the player’s limb data with the position of the ball on the field and an artificial intelligence trained to recognize offside situations, the new technology automatically sends out an alert to the control room. every time an attacking player receives the ball from an offside position.

Before notifying the on-field referee, the executive room will manually re-check the situation – a process described by FIFA that will take ” several seconds” and means offside decisions will be made faster. and more precise .”

Once the final decision is made, the data points will be used to reconstruct a 3D simulation of the offside situation. This simulated image will also be broadcast on large screens in the stadium as well as broadcast via television to viewers around the globe.

Not an “offside robot”

Before being officially applied at the Qatar 2022 World Cup, this semi-automatic offside detection technology has been successfully tested at many other official and test FIFA tournaments, including the FIFA Arab Cup 2021 and FIFA. Club World Cup 2021.

In these tournaments, new technology has shown to help referees make offside decisions faster, more accurately, and easier to reproduce. In addition, the data collected from these tournaments has also been analyzed and validated from the MIT Sports Lab and the University of Victoria.

Renowned referee, currently Chairman of the FIFA Arbitration Committee, Pierluigi Collina said: ” The test has been a great success and we are confident that, in Qatar, we will have a tool to assist us. valuable to help referees and assistant referees make the best and most accurate decisions on the pitch I know that some people call this an “offside robot” but it is not. The referee is still responsible for making decisions on the pitch .”
