The Dhaka Times Desk Several new and amazing technologies are being used in this FIFA World Cup. Moments that change the outcome of the game.
At the top of the discussion among these technologies is the name of VAR or Video Assistant Referee. Thanks to which several goals have fallen in the offside. Moreover, for the first time in the FIFA World Cup, the use of live ball-tracking technology is also seen. Today's discussion is about special tracking technology.
How Live Ball-Tracking Works
The balls used in this year's FIFA World Cup, designed by German AI solutions provider Kinexon, also have a lightweight sensor inside them. These sensors, developed by the International Measurement Unit (IMU), can provide real-time spatial position and displacement information using ultra-wideband (UWB) radio frequencies. Kinexon's own Local Positioning System (LPS) also makes tracking the ball's motion possible. It is installed right around the pitch of the matches. Through which referees and officials can see where the ball is going, where the players are positioned, where they are changing direction from one position, to be aware of what is actually happening around the field at all times.
According to Kinnexon's website, the sensor inside the ball can detect both 2D and 3D motion, output in real time, and provide centimeter-accurate measurements in less than 20 microseconds.
How ball-tracking helps
According to information on Kinexon's website, it is possible to accurately identify the performance of specific players with the help of automatic technology of live ball tracking. In addition, in complex situations such as goals, penalties and offsides, analysts can use up-to-date, real-time data to be sure of how each player is performing. The information from the sensor also acts as a data package. This includes the distance covered by the ball, acceleration and speed of the ball, how far players run during attack and defense, dribbling speed at any given time, speed at which the ball is shot at goal, accuracy of the team's passing. Kinexon's tracking sensors help visualize real-time data for better presentation during live matches, a press release said.
