Like I mentioned in the previous post here on the blog, I’ve gotten quite interesting in the future of cameras. Which technology they will have, how they’ll differ from the cameras we know today, and the new areas these will be useful in. I’ve just stumbled across an area in which cameras are used which was unknown to me – football.
I’ve never been much of a sports enthusiast myself, but one of my best friends is. He also likes to bet on his team in Premier League, and he keeps sending me links to a page called oddsexpert.co.uk so I can join him. I actually used ther reviews-section and signed up to a betting site – and what’s worse is that I actually enjoyed playing. So I’ve gotten a bit into football lately – hence this blogpost.
I was watching a match that I had placed a bet on, and in the second half there was a weird situation. I thought that my team scored a goal, but the referee didn’t see that the ball crossed the goal line. I figured that there must be some way to measure if a ball crosses the line or not – and apperantly there is.
It’s called goal-line technology. The technology i read about was called Hawk-Eye, but I’ve also come to the understanding that there are other systems as well. The Hawk-Eye system uses high-speed video cameras, that can assist the referee in his decision-making. The network of cameras can track the ball’s position in the field at any given time using triangulation. Since the technology can know the ball’s position, Hawk-Eye can tell when the ball has crossed the goal line. What happens then is that the system will alert the match officials through radio transmission or the referee´s watch.
The camera technology is obviously very smart, and it can even predict the future path of a ball. It can tell how the ball would have traveled if, for example, it wouldn’t have touched a defender. Since visual displays like these are possible, the system will probably be popular for TV-broadcasted matches. I know for sure that I would watch the camera’s work in amazement!
