Tennis players failing Hawk-Eye challengeJanuary 30th, 2009 - 2:34 pm ICT by ANI
Melbourne, Jan.30 (ANI): The world’’s leading tennis players have been exposed as poor judges in contentious line calls at the Australian Open, feels Hawk-Eye.
By the end of the day session on Thursday, male players had made 286 challenges at Melbourne Park. Of those, only 89 - or 31.12 per cent - were successful. Hawk-Eye said the players were wrong 197 times.
It is a similar tale of optical illusion with the women.
A total of 171 challenges have been made so far, with just 47 - or 27.49 per cent - successful.
Several players, notably Federer, detest the system.
Federer ranks second on the list of the most unsuccessful male players using the system.
His 19 challenges have returned only five overrules in his favour.
Murray got two of 17 right. Gilles Simon five of 18.
Dokic (six of 15), Jankovic (three of 12) and Alize Cornet and Daniela Hantuchova (one of nine) also got it badly wrong.
Safina has been right only seven of 17 times.
International Tennis Federation testing in 2006 claimed that Hawk-Eye made the “correct call in 100 per cent all tests, showing an average error of only 3.6mm”.
Hawk-Eye is based on the principle of triangulation using the visual images and timing data provided by high-speed video cameras located at different positions around the area of play.
The system rapidly processes the video feeds by a video processor and ball tracker. A data store contains a predefined model of the playing area and includes data on the rules of the game. It has been controversial in its short tennis life. (ANI)
