Barely three minutes of the Qatar 2022 World Cup passed for FIFA to use for the first time in the history of the highest soccer competition the new semi-automatic offside detection system in the opening match between the host team and Ecuador, for Group A .
The striker Enner Valencia came out to celebrate the first goal of the World Cup after a header in the six-yard box but the Italian referee Daniele Orsato, with the teams ready to serve from the central point, received the warning from his assistants to invalidate the action.
The images showed that Valencia’s right foot was in an illegal position. It was not specified how many centimeters it was, but it could be seen that this undue presence was really very scarce.
Thus, FIFA launched the semi-automated technology program based on twelve cameras installed under the roof of the stadiums, which make it possible to capture the movements of the ball and up to 29 data points of each player, 50 times per second, to calculate their exact positions on the ground. pitch.
The 29 groups of data collected from each soccer player include the extremities and parts of the body that are taken into account to indicate whether or not a position is enabled by regulation.
Social networks were immediately filled with comments and Argentines, mainly, were the most critical of the use of technology in soccer. It is that in our country there were many doubtful plays that were annulled or validated at the time of drawing lines that are not very convincing. Here the system is different and, at least, in less than a minute it was reviewed, canceled and there was not much room for debate, at least on the pitch.
The play that was reviewed but not shown on the screen was Ecuador’s second goal, in which Valencia himself appeared to be a few inches ahead when he fired a cross from the right.
CHIP ON THE BALL
The official Adidas Al Rihla ball includes an inertial measurement unit (IMU) inside, decisive for the detection of offsides. This sensor, located in the center of the ball, sends a data packet 500 times per second to the video room, providing extreme precision on the exact moment the ball hits, a fundamental criterion for determining an offside position.
With the crossing of data collected by the devices and artificial intelligence, the new technology sends an immediate warning to the video arbitration booth every time a player located in a prohibited position receives the ball from a teammate.
The VAR room team checks the information received by the system and then notifies the main referee through the intercoms so that the decision can be executed.
