Video Assistant Referee (VAR) in football is generally used to stay in charge; The same reason is that they take a long time to complete the task. It therefore has a significant impact on the conduct of the match as FIFA stated that in some cases, the VAR took more than four minutes to make offside decisions. Now, technology has made a promise by proposing to reduce the time to just three or four seconds.
Semi-automated VAR is a technology based on artificial intelligence (AI). The technology will likely be used at the World Cup later this year and has been indicted by the International Football Association Board (IFAB). The IFAB is responsible, or we can say that the role of the IFAB is to shape the rules and regulations of the FIFA World Cup.
FIFA President Gianni Infantino stated, “It looks very impressive and promising as well.” “The team of experts will conduct a trial before the board makes a decision on whether or not it is certain to be used for the World Cup.”
What do you mean by semi-automatic VAR?
Semi-automated VAR is an essential feature or technology that makes quick stealth decisions rather than getting bogged down in the existing system. In some cases, it becomes difficult to determine how long VAR technology will last.
The technology based on artificial intelligence detects the ball automatically. The technology will create a 3D model of the player’s position in real time, thus improving the accuracy of the kick point. The product relies on tracking data and sensor technology from camera systems, while at the same time, the player’s skeleton will be designed to determine which part of the body was facing at the same time.
The technology is “based on limb tracking technology or skeletal tracking technology,” said Johannes Holzmüller, director of football technology and innovation. “We called it a semi-auto offside because it’s still, in the end, the VAR who has to check and confirm the proposed offside line, and then the VAR informs the referee on the field of the decision,” Holzmueller said on FIFA Live Football. .
How many cameras does it have
Semi-automated stealth consists of different cameras as it is a camera based system. There are about 10-12 cameras installed inside the stadium and under the roof. The role of these cameras is to follow players and track up to 29 data points at a rate of 50 times per second, then this data is processed almost in real time and computed by the bot by artificial intelligence. Further, this data is automatically sent to VAR, and the restart trigger occurs. ”
The main motivation was to determine the exact moment the player kicked the ball. Then, the next step is to determine which part of the attacker or the last defender is closest to the goal line.
Strength is still with the rulers
FIFA’s chief refereeing officer is Pierluigi Collina, who said that the final decision will remain with the officials on the field, and this technology is only available to help them reach a more accurate decision. “Referees and assistant referees have to make decisions on the field. Technology only gives them valuable support to make more accurate and quick decisions. Especially when the offside incident is very narrow and difficult,” he said at the Club World Cup launch event.
The Club World Cup Experience
The technology was tested at the Arab Cup in December, but it wasn’t until the FIFA Club World Cup in February that we envisioned exactly what the VAR intrusion would look like to fans.
The new Hawk-eye system creates a 3D simulation of stealth resolution, and fans can now visualize the player as an offside while the simulation moves parallel to the players.
