近日，卡塔尔世界杯期间，“半自动越位识别”系统在小组赛C组首轮比赛中，上半场两次吹掉了阿根廷的进球，引发广泛关注。这是“半自动越位识别”技术首次被应用于世界杯舞台。

This sensor, positioned in the centre of the ball, sends ball data to the video operation room 500 times per second, allowing a very precise detection of the kick point.

The new technology uses 12 dedicated tracking cameras mounted underneath the roof of the stadium to track the ball and up to 29 data points of each individual player, 50 times per second, calculating their exact position on the pitch.

国际足联主席因凡蒂诺（Gianni Infantino）表示，这项技术是三年专门研究和测试的结晶，旨在为卡塔尔世界杯提供最好的支持。国际足联致力于利用技术改善各个级别的足球比赛，而在2022年世界杯上使用“半自动越位识别”技术是最直接的体现。

"This technology is the culmination of three years of dedicated research and testing to provide the very best for the teams, players and fans who will be heading to Qatar later this year…FIFA is committed to harnessing technology to improve the game of football at all levels, and the use of semi-automated offside technology at the FIFA World Cup in 2022 is the clearest possible evidence."

"This innovative system will allow VAR teams to determine offside situations quickly and more accurately, enhancing the flow of the game and the consistency of the decisions."

"(It) gives us the possibility to be faster and more accurate in terms of decisions about offside," Collina told reporters in a briefing ahead of the tournament.
