The 2022 Qatar World Cup, kicking new ideas this year. (two)
2022-08-20 16:04The last article mentioned that Qatar spent a lot of money to renovate and rebuild the stadium in order to host the World Cup . The architectural design perfectly reflects the Arab culture and history. I believe that after the World Cup is over, it will become a landmark tourist attraction. Although this year's World Cup is scheduled to be held in winter, temperatures are expected to be only 18 to 24 degrees Celsius.
In addition to the interior and exterior design of the building, the country has also integrated thermal insulation materials and cooling technology into each competition, just to create a more comfortable competition environment. It's just that the stadium will be bigger.
artificial intelligence referee
Fans who watch football games on weekdays will find on TV that there is a referee on the football field, running around with the football players to see if they have violated the rules. In order to greatly reduce the misjudgment of offside, this year Qatar World officially used semi-automatic offside penalty technology, a total of 12 cameras tracked each player's 29 data points.
The artificial intelligence referee, of course, is not as simple as using a few more lenses. It is said that an inertial measurement unit sensor will be placed in the center of each ball to send data to the VAR operation room at a frequency of 500 times per second. Kick off the sensor inside!
Increased number of players
Considering that the 2022 Qatar World Cup will be affected by the new crown virus, and the schedule of the game will be different from the previous World Cup, FIFA has increased the number of participants from 35 to 55 through the participation of each team . In addition, during the game, a maximum of 15 substitute players and 11 staff members can sit on the bench, a total of 26 people, including a famous doctor.
For Qatar, this year's World Cup is just a good time to make this long-term investment. Although a lot of money has been invested, most of the facilities built or beautified for the game, including hotels, transportation, innovation centers at the airport, etc., the World Cup is over. will continue to use.
