Here in England & Wales the Football (Soccer) Premier league has just introduced Hawk-eye to determine whether a ball has completely crossed the goal line.
In near real-time, 7 HD cameras at 500 fps are used to triangulate the location of the ball wrt. the goal line. The system sends a message to the referee. There is a whole lot of maths, computing and communicating going on and the system is likely expensive to install and administer.
My Sunday morning pub team needs a similar system and I wonder how much of it is viable on the Pi ?
Unfortunately our goalkeeper has a very round head and no hair so I would imagine it might confuse ball-recognition algorithms.
Items under consideration:
1. Face/ball recognition,
2. Pixel mapping,
3. Live video streaming,
Anything I've missed ?
I've toyed with the idea of a Kickstarter project but the resulting puns would be un-bearable (Babbage etc.)
If all goes well Sepp Blatter has agreed to allow me to trial it on April 1st at our home ground at Hackney Marshes.
