New areas for camera use

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.

Hawk-Eye - a camera system used for football matches!

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!

 

The next generation of cameras

I know it´s been quite a while since I last posted here, but I haven’t really had any motivation to write anything. The other day I did however get stuck at Wikipedia and the rest of the internet for a while, so I figured I should update you with what I found this time. Since my last post was about camera history it’s almost a bit ironic that this post is about the future, and the next generation of cameras.

What I found is that there’s probably a big revolution coming in the world of cameras. We might think that the cameras has gotten very far, considering the technology we have for them in our phones for example. We can take slo-mo videos in ultra-high definitions, and the phone cameras can even recognize faces. But this is all just the beginning of a brand new era of cameras.

I read about a lot of things that were coming on the market, but there was one thing in particular that cought my attention. That thing was perhaps an extreme example, but it really does make you curious about what the future holds. The thing I’m talking about is called single pixle cameras, which is kind of the opposite to how regular cameras with a lot of pixels works. A single pixle camera needs a controlled light source, like for example a simple data projector that illuminates the scene one spot at a time. That way, you can then measure the amount of reflected light and add it all together to one single image.

How a single pixel camera works!

A camera like that could be used to take photos through thick falliong snow or fog. It’s even possible to capture imager from light particles that doesn’t even interact with the photographed object. That would be a way to use the “quantum entanglement”, which is that two particles can be connected so that the same thing always happen to the both of them even though they are far apart. That could be very interesting when it comes to taking pictures of things that change depenting on the light. Like, would a retina photographed in the dark look the same as when photographed in the light?

To me, this sounds like some kind of sci-fi thing. I have a hard time keeping up with the developement of technology, so it’s difficult for me to understand that things like these are real. I even got blown away by the fact that you can play online casino in your phone yesterday when I read about casino on a site called casinonodeposit.co.uk. Isn’t it amazing how great technology is nowadays?
