The 2022 World Cup in Qatar kicked off, and the AI-powered semi-automatic offside technology played a role in the first game

On the evening of the 20th, the 2022 World Cup in Qatar officially opened. In the ensuing game, Ecuador defeated Qatar 2-0, breaking the legend of "the host of the World Cup opener is undefeated".

As we all know, in ball games, referees have different judgment standards, and even "blowing the black whistle" is often criticized, which not only affects the fairness and justice of the game, but is more likely to cause disturbances and even conflicts. The old core of the hot pen will come to play a game today, how to use technology to make the game more fair and just in the World Cup in Qatar.

Soccer built-in chip collects high-precision data

As early as the 2018 World Cup in Russia, the game ball has a built-in NFC chip, which can record the details of the game such as the trajectory of the player and the player's shot.

In the 2022 Qatar World Cup, the game ball continues to have a built-in chip, and it is further upgraded and iterated to collect high-precision football data in real time, send the data at a frequency of 500 times per second, and hand it over to the artificial intelligence system for integration and analysis. When fouls such as offside are detected, the data will be sent to the video assistant referee (VAR) to help the referee make reasonable, fair and accurate decisions.

Real-time video capture, accurate location determination

Another technical highlight of the Qatar World Cup is the first official use of semi-automatic offside detection technology (SAOT). Through 12 special cameras on the top of the stadium, video motion capture technology is used to track 29 positioning points on the player's body to accurately determine the relative position between the football and the player. position, the artificial intelligence system automatically draws a virtual offside line.

In addition, with the help of multi-angle and multi-camera cameras, video slow-motion playback can be used to assist referees to make objective and fair judgments. In the face of controversy, there is also sufficient video data and sports data to support it.

3D animation images released in real time

When the referee completes the penalty, the SAOT system will combine the data collected by the football's built-in chip to generate a 3D animation image within a few seconds, and announce it on the field, so as to show the audience the basis for the referee's decision to dispel fans. doubts, make the game more fair and just, and reduce the interference of subjective factors.

Driven by technology, the World Cup will be more transparent and fair, allowing more people to enjoy the charm of the World Cup.
