Hawk-Eye is a complex computer system used in cricket,tennis and other sports to visually track the path of the ball and display a record of its most statistically likely path as a moving image. It is also used in some instances to predict the future path of a ball in cricket. It was developed by engineers at Roke Manor Rearch Limited in the UK, in 2001. All Hawk-Eye systems are based on the principles of triangulation  using the visual images and timing data provided by at least four high-speed video cameras located at different locations and angles around the area of play. The system rapidly processes the video feeds by a high-speedvideo processor and ball tracker. A data store contains a predefined model of the playing area and includes data on the rules of the game.
