The ***Hawk-Eye*** thread

Post anything Hawk-Eye related here.

Here is what Wikipedia has to say about Hawk-Eye.

"Hawk-Eye is a computer system used in cricket, tennis and other sports to visually track the path of the ball and display a record of its actual path as graphic image. In some sports, like tennis, it is now part of the adjudication process. It is also able to predict the future path of a ball. It was developed by engineers at Roke Manor Research Limited of Romsey, Hampshire in the UK, in 2001. A UK patent was submitted by Dr Paul Hawkins and David Sherry[1]. A US, European and Australian patent for ball tracking is held by Auto-Ref Inc. of Toronto, Ontario. Later, the technology was spun off into a separate company, Hawk-Eye Innovations Ltd., as a joint venture with television production company Sunset + Vine."

Re: The ***Hawk-Eye*** thread

Ok.

1. Having 3 challenges is garbage. Put it back to 2.
2. Umpires are letting players take too long to decide. Hurry it up. Fedmug does it right.
3. Players shouldn't be allowed to ask their box. That takes too long and is technically coaching anyway.

Re: The ***Hawk-Eye*** thread

I'd have to agree with you leng jai. Your spot on.

What about the future of hawk-eye.
Does anyone feel that the system could change to some degree?

Accurate and Reliable


During ITF testing in 2006 Hawk-Eye made the correct call in 100% of all tests, showing an average error of only 3.6mm. The system recorded 100% of all rallies.
Tests have always been conducted outdoors, encompassing situations that take the following factors into consideration:
Wind (and therefore camera wobble);
Bright sunlight at different times of the day;
Shadows covering part or the majority of the court;
Dark or overcast conditions;
Artifical floodlights.
Indoor venues are obviously easier in which to track because conditions are far less variable. Quite simply, Hawk-Eye can track accurately and reliable in any conditions, on any surface.
Although the accuracy of the existing system has been tried and tested, the company is constantly trying to develop and refine the system. Hawk-Eye listens to feedback from customers and officials to ensure that Hawk-Eye remains the very best in the market.
How does it work?




2D (x,y)
Vision processing is used to identify the centre of the ball within each frame of each camera. Camera movement is compensated for by also tracking the lines of the court.

.



3D (x,y,z)
The system triangulates the information from each calibrated camera to provide the 3D position of the ball.

.



4D (x,y,z,t)
This process is repeated for each frame so that the 3D positions of the ball can be combined to produce a single trajectory of the flight of the ball.

.



Bounce Mark
The trajectory is then used to calculate at exact bounce contact area the ball made with the court.

Hawk-Eye on TV


Hawk-Eye is now vastly experienced in working alongside TV broadcasters, providing calls that are not challenged (or close calls if the official system is not in place) and an array of illuminating statistics to improve the overall viewing experience.
A great deal of software expertise had been expended on improving our Virtual Reality 'look' in 2007, meaning Hawk-Eye can tell even more of the statistical stories relevant to the match in hand. Hawk-Eye’s bank of graphics is constantly expanding as TV commentators and producers express different ideas and feedback. TV Commentator and Hawk-Eye Analyst, Jason Goodall remarks on the natural addtion of Hawk-Eye statistics to sports commentary,
“I think the data that Hawk-Eye is able to capture and process in user-friendly form is invaluable in helping us all gain a unique insight into how the best players in the world are able to achieve all they do. Not only are we able to sit back and enjoy watching the world's best compete with one another, now with the help of Hawk-Eye we can also learn from them too."


Jason Goodall


Some examples of our work (as featured at the Sony Ericsson Championships 2007 in Madrid) can be found below:










I like the way it is right now. I would love to hear more alternatives though.
