Semi-automated offside technology will be used at this year's World Cup in Qatar, promising decisions that are "more accurate and a lot quicker," FIFA said on Friday. In what can be considered an "extraordinary development in the officiating of the game," technology will be able to "resolve contentious offside calls with a speed and accuracy unimaginable less than a decade ago." Using cameras strategically positioned around the stadiums, and a chip in the match ball, FIFA said the technology will go a long way to cutting down on continuous VAR decisions on marginal offside calls and reduce the time needed to check. The technology has already been tested at two tournaments over the last seven months and had been expected to be approved for the World Cup in Qatar from Nov. 21-Dec. 18. It will be used at all the venues at the tournament (REUTERS, 7/1).
The so-called Semi-Automated Offside Technology relies on 12 optical tracking cameras, which track 29 points on the body for every player at a rate of 50 times per second, in conjunction with an inertial sensor embedded in the match ball transmitting at 500 hertz. See more in SportTechie.
