This World Cup uses two major technological assistance:
Semi-automatic offside technique
The 2022 World Cup in Qatar will use semi-automatic offside penalty technology to assist referees in making accurate offside penalties. Twelve dedicated cameras will be set up under the top of each stadium in the World Cup in Qatar to track 29 items of data about the football and each player, and collect data at a high frequency of 50 times per second to confirm the specific coordinates of the ball and players on the field. The coordinates of each part of the player's body will be recorded, which can ensure more accurate offside penalties.
According to this technology, a sensor will be placed inside the Qatar World Cup ball "Al Rihla", and the device will send ball data to the video referee team at a frequency of 500 times per second, so as to ensure accurate judgment of the player's point of contact with the ball .
With the help of artificial intelligence technology, the technology will provide automatic offside alerts for video assistant referees. Before notifying the referee on the field, the video referee will conduct two checks to determine whether the effective position of the player (possibly limbs, torso) is offside. This process can be completed within a few seconds.
After the video assistant referee assists the referee to confirm the result of the penalty, a 3D animation will be generated through the collected data, and the reason for the offside penalty will be explained from the best perspective.
Stadium Cooling Technology
Although the 2022 World Cup in Qatar will be held between November and December, the temperature in the Gulf region may still reach around 25°C-30°C. In order to reduce the temperature to 18°C-24°C, the stadium is equipped with cooling technology and a retractable roof to provide athletes and fans with a more comfortable playing and watching environment.
Seven of the eight stadiums in this World Cup have adopted advanced cooling technology to keep the inside of the stadium cool and pleasant. Not using the technology is the naturally ventilated 974 Stadium, which requires no cooling thanks to its proximity to the coast.
There will be an energy center adjacent to the stadium, from which cold water will be piped to the venue. Ventilation vents are installed around the football field and below the auditorium, and during the game, cold air will be continuously pushed from the vents to the field and the audience area. This system mainly uses the heat energy converted from solar energy for cooling, and the cold air is circulated through the pipes to the entire stadium. This is also the first time such a technique has been used.
In addition, the unique retractable roof significantly improves the cooling process, meaning that the water and energy usage required for the air-conditioning system is not overtaxed. In case of bad weather, the retractable roof can also be closed.
