Hawk-Eye Innovations officiating systems for tennis matches can work alongside TV broadcasters and provide calls that are not challenged (or close calls if the official system is not in place) and statistics to improve the overall viewing experience.
A typical Hawk-Eye tennis system has around 10 cameras positioned around the court, usually located high up in the stadium seating area.
Hawk-Eye then operates the system from a control room within the stadium. The data from the cameras is sent via several computers to create a 3D position of where the ball landed, this is then converted into the virtual world to display an output on the big screen.
The system added an exciting dimension to TV coverage by converting tracked data into statistical patterns to demonstrate trends, comparisons and speeds.
The software has recently been expanded to improve the virtual image to allow a bank of graphics to assist TV commentators and producers in expressing different ideas and feedback on the game.
This ball-tracking system passed stringent International Tennis Federation (ITF) testing in accuracy, reliability and practicality. During ITF testing in 2006 - both indoor and outdoor, on all surfaces and in variable weather and light conditions - it scored 100 per cent accuracy.
