These Headlights Can Assist Drivers See through Snow, Rain

Scientists, comprising one of Indian origin, have designed a smart headlight system. For the first time in history, this headlight system can assist drivers see through intense snowfall or rain and securely find the way at the time of stormy nights. The system developed by scientists in the U.S. at Carnegie Mellon University enhances visibility by continually transmitting light to shine amid particles of rainfall.

It avoids the dangerous and ever-lasting distracting glare that takes place when headlight rays are reflected by rainfall back to the driver. “If you are driving in a heavy rainfall, the smart headlights will make it appear as if it is a light drizzle,” claimed Associate Professor of robotics at Carnegie Mellon University, Srinivasa Narasimhan. The system utilizes a camera to trail the motion of snowflakes and raindrops and then implies a computer algorithm to estimate where those particles will be within a fraction of second.

The light projection system then regulates to disable light beams that would rather be used to highlight the particles in their estimated positions. “A naked eye will be unable to view that shimmer of the headlights,” Narasimhan claimed. “And due to the rainfall particles not being highlighted, the driver will not see the snow or rain either.” To individuals, rain can emerge as extended streaks that appear to fill the atmosphere.

That leaves a lot of space amid the drops where light can be efficiently dispersed if the system can react quickly. Lab experiments confirmed that the smart headlight system can sense raindrops, estimate its movement, and regulate a light projector within a fraction of second. At low speed, such a system could get rid of 70% to 80% of perceptible rain at the time of a heavy shower, while losing only 5% or 6% of the light from the car. To function at highway speed and to operate efficiently in hail and snow, the response of the system will need to be lowered to merely a few milliseconds. Lab experiments have confirmed the possibility of the system and the scientists are sure that the speed of the system can be powered.
