Smart Headlight for seeing through Rain and Snow

Headlights they illuminate raindrops and snowflakes, making them streaks that can distract drivers. Now a team led by Carnegie Mellon computer science professor Srinivasa Narasimhan, has developed an experimental headlight system, that can shine ‘around rain’ while tackling the problem of visibility.

How it Works
“The headlight is a co-located imaging and illumination system consisting of a projector, camera, and 50/50 beamsplitter. The camera images the precipitation at the top of the field of view, the processor determines the future locations of the particles and the projector reacts to dis-illuminate the particles. The entire process from capture to reaction takes about 13 ms.”
