Hawk-Eye is a technology system used in sports to track the trajectory of balls and players. It employs multiple high-speed cameras positioned around the field or court to capture real-time data. This information is then processed to provide accurate visual representations of events, such as whether a ball is in or out of play. The system is widely used in various sports, including tennis, cricket, and soccer. It enhances the accuracy of officiating decisions and provides fans with a clearer understanding of the game. Hawk-Eye has become an essential tool for improving fairness and transparency in competitive sports.
