FIFA will track players' bodies using AI to make offside calls at 2022 World Cup


FIFA, the international governing body of association football,* has announced it will use AI-powered cameras to help referees make offside calls at the 2022 World Cup. The semi-automated system consists of a sensor in the ball that relays its position on the field 500 times a second, and 12 tracking cameras mounted underneath the roof of stadiums, which use machine learning to track 29 points in players' bodies. Software will combine this data to generate automated alerts when players commit offside offenses (that is: when they're nearer to the other team's goal than their second-last opponent and receiving the ball). Alerts will be sent to officials in a nearby control room, who will validate the decision and tell referees on the field what call to make. FIFA claims this process will happen "within a few seconds and means that offside decisions can be made faster and more accurately."
