[Music] welcome to the Circuit news since the beginning of sports there have been bad calls and angry fans but in the last 20 years things are changing first there was a 2004 U.S open then there was a 2010 World Cup and the goal that never was sports are now turning to robot umpires and digital referees no not exactly like this but instead a computer vision technology called Hawkeye this is Paul Hawkins The Man Who Saved tennis and other sports from bad calls having studied artificial intelligen
ce in England Hawkins created a system with cameras that could track a ball and predict its path it was originally created for Cricket but tennis was the first sport to pick it up worldwide starting in 2006 it's been reducing Tantrums ever since becoming a standard tool on the court while you might think that Hawkeye is showing you what happened it's actually calculating and projecting what's going to happen based on the trajectory of the ball at 340 frames per second the computer generates 340
different positions of the ball all per second allowing it to very accurately predict where the ball will bounce before it even touches the ground fancy algorithms that take into account ball compression and skid create that bounce Mark that we see on the screen and just like line judges and Tennis umpires in baseball yeah they can also make human errors this year all 30 teams in minor league baseball introduced an automated ball in strike system or ABS also known as Robo upps to make better cal
ls during the game using the Hawkeye tracking system the cameras and sensors above the home plate detect the strike zone based on the player's height and once it determines if the pitch was a ball or a strike a robotic voice tells the Umpire through an earpiece to decide what call to make in AAA baseball this year half the games use the robots for ball strike calls which teams can choose to appeal but robot umpires aren't being called up to the bigleys yet MLB commissioner Rob Manfred says abs i
s unlikely to be used in the 2024 season soccer is also saying goodbye to those iffy calls with Hawkeye a virtual assistant referee or bar introduced for the first time in the 2018 World Cup held in Russia there are two versions to their offside technology a single camera that draws a calibrated blue line and then there's the version that uses multiple cameras to triangulate the body parts to detect if the player is leading forward for example and that is also used when the Zar is happy with the
decision that they can confirm the positions of the lines so that they can then be sent out to television or to spectation and stadium so they can understand exactly where the lines have been placed and where they correspond to on the on the player's body but like tennis where the shot spot has the final say the referee makes the final call on whether or not to go with what the system decided and while some bands would say bar is a mood killer the people President says that without the VAR a re
feree can make important Stakes every three matches but with the bar it's every 19 matches meanwhile at Georgia Tech a software engineer taught himself computer vision AI to create a digital referee for basketball there's like 18 different key points on the players everything is detected by this model and has the coordinates of every single position of your body points he used over 3 000 photos to train the model to track the ball's movement and the position of a player's ankles and wrists to de
tect double dribbling and traveling violations he's now working on version 3.0 which will include the capacity for multiple players cameras and the ability to detect shooting files and reach in with basketball is that it's really fast paced and for referees it's very difficult in some angles especially to see all parts of the court paii is also developing a mobile app that he hopes will bring accurate officiating to youth leagues and pick up games around the world that's all the time we have for
now thanks for joining us we'll see you right here again circuit news TV foreign
