How does a Hawk-Eye Operate?
In each frame sent from each camera, the system identifies the group of pixels which corresponds to the image of the ball. It then calculates for each frame the 3D position of the ball by comparing its position on at least two of the physically separate cameras at the same instant in time. Each frame builds the path along which the ball travelled. The system generates a graphic image of the ball path and playing area, which means that information can be provided to judges, television viewers or coaching staff.
