Hawk-Eye is the name of a line calling system which trace a ball’s trajectory and sends is a virtual reality machine.

How does Hawk-Eye work :
Hawk-Eye uses 6 high-speed expert vision processing cameras which are located round the ground and calibrated. In inclusion, the system uses the two “Mat” broadcast cameras and calibrates them so that the visual is often always overlaid within the right place.

All cameras have “anti-wobble” software to deal with camera motion. When a ball is bowled, the system is in a position to automatically identify and find the ball within each and every frame of video from each camera. By combining the positions of the ball in each of the camera frames, the 3d and 4d positioning of the ball is measured through-out the delivery. The delivery is broken down into two independent components: delivery to bounce and bounce to impact. By measuring the position of the ball at multiple frames the speed, direction of travel, post and pre bounce, swing and dip are often can be calculated for that specific delivery. No inherent characteristics of the pitch are required as part of the system apart from deliveries which hit the batsman on the full. Using these measured characteristics of the ball’s flight up to impact, the future path is forecasted.

Examples of Hawk-Eye statistics include:

  • LBWs
  • Wagon Wheels
  • DeSpin
  • Pitch Maps
  • Beehives
  • RailCam
  • Reaction Time
  • Ball Speeds

The Hawk-Eye System comprises of two main elements: a Tracking System and a Video Replay System. The Video Replay System offers the optional component of a high-speed and accurate camera, which might provide more in-depth biomechanical analysis and interpretation.
