Anyone who's ever driven through a heavy rain has hoped for something like this: a system that can make rain drops vanish--or at least look like they do.
Intel and Carnegie Mellon University have developed technology that makes it happen, CNET reports. Each headlight projects not just a single beam, but a grid of several tiny beams (that's how the different-colored pixels are projected on the screen when there's actually an image being shown).
A camera behind the projector watches for raindrops, and a processor predicts their paths. Then the projector blocks out just the part of the grid where the rain is falling, darkening just the pixels in its way. Presto: a rainless view.
Intel says it'll be available in a decade, and even though it's not quite perfect--some drops still look like they sneak through, at least at the top of the driver's range of vision--it seems like a major safety improvement from windshield wipers and a prayer.
Pretty sure that's snow in the clip. Must work the same either way, though driving through snow is a lot different then driving through rain.
Seem like a long time, it must more then technical problems, probably costs to much.
Nice as a thesis project, but long before this becomes half feasible, we will have self-driving cars. Useless.
We could always be surprise with a sudden upgrade of processors or other technology and then POOF the above proposal technology arrives sooner.
Hasn't this been reported here before?
Anyway the tech seems impractical right now, but if they actually get this to work it could be indispensable in cars of the future and even sports goggles, protective eye wear etc.
So it just doesn't shine any light on the individual rain drops? If the rain gets too heavy, wouldn't that just be the same as turning your headlights off?
Jason... you will be LONG rotting in a grave before the majority of cars on the road are self driving.
I never had these issues. Who can't drive if their headlights are wet? It is the windshield that needs to remain as dry as possible, and all we need for that is a hydrophobic film on it. I never thought "Gully, I could see a lot better if my wipers were dry"
12, I wouldn't count on it. Processing technology has been stuck on the same pace since it was invented.
