Toward a
Smart Automotive Headlight for Seeing
Through Rain and Snow
Standard
vehicle headlights improve driver visibility at night by illuminating the road
and the surrounding environment. Unfortunately, they also illuminate raindrops
and snowflakes making them appear as bright flickering streaks that are
distracting to the driver. We propose a headlight capable of avoiding
precipitation to improve driver visibility while adequately illuminating the
road. This reduces driver stress and makes roads more safe during rain and snow
storms. We have conducted simulations and built a prototype system to show that
the approach is feasible and effective. Demonstration of the prototype system
with an artificial rain drop generator is encouraging making the falling rain
disappear in front of the observer.
