FIFA World Cup 2022 will feature semi-automated offside technology

 Fifa has announced a new technology in Qatar which detcts the ball and kepp track of all the player providing a tool to assist video match officials and on-field officials in making faster, more accurate, and repeatable offside rulings on the greatest stage of all

Technology uses;

• 12 dedicated tracking cameras mounted underneath the roof of the stadium to track the ball
• 29 data points of each individual player, 50 times per second, calculating their exact position on the pitch.

• The 29 collected data points include all limbs and extremities that are relevant for making offside calls.

Al Rihla, adidas' official match ball for Qatar 2022TM, will have an inertial measuring unit (IMU) sensor, which will aid in the identification of close offside events. This sensor, located in the centre of the ball, transmits ball data to the video operating room 500 times per second, allowing for extremely accurate identification of the kick spot.

The new technology, which combines limb- and ball-tracking data and employs artificial intelligence, sends an automated offside alert to video match officials inside the video operation room whenever the ball is received by an attacker who was in an offside position at the time the ball was played by a teammate. Before contacting the on-field referee, the video match officials personally review the automatically determined kick point and the automatically constructed offside line, which are based on the computed locations of the players' limbs. This procedure takes only a few seconds, allowing offside judgments to be made more quickly and correctly.

THIS IS THE DEVICE WICH IS USED IN FOOTBALL:

After the decision is validated by the video match officials and the referee on the field, the exact same positional data points used to make the judgement are created into a 3D animation that accurately specifies the location of the players' limbs at the instant the ball was played. This 3D animation, which will always depict the greatest potential viewpoints for an offside scenario, will subsequently be projected on the stadium's enormous screens and made available to FIFA's broadcast partners in order to notify all fans as clearly as possible.
