Take a look at the LIDAR and integrated photonics technologies that help self-driving cars navigate obstacles, no matter the environment, weather or light.
--
It’s late, pitch dark and a self-driving car winds down a narrow country road. Suddenly, three hazards appear at the same time. With no human at the wheel, the car uses smart eyes, sensors that’ll resolve these details all in a split-second. How is this possible? Sajan Saini explains how LIDAR and integrated photonics technology make self-driving cars a reality.

Havent thought of this before! The scientists and engineers who invented LIDAR are really innovative. Can LIDARs see color too?

@makarlock 5 жыл бұрын

Yeah except...visual resolution of lidar (like color) is abysmal-especially for now. Like Elon said, the roads are made for eyes: rely on vision first, supplement with lidar and ultrasonics. I do have to say, mega respect to Ted-Ed, and it’s cool that they talking about the actual electronics of it.

Real N He does have a point though, while Lidar as a technology is cool, camera technology is getting to a point where it’s no longer necessary.

@McHrozni 5 жыл бұрын

@@jerry3790 LIDAR is inherently better. With camera you're making the machine operate as a human would. That's like designing a car with legs. Sure, it would be cool. I love AT-ATs. But wheels are just so much more practical on a machine. Let a machine be a machine and not emulate nature when there is a better way. Eventually I expect to use a combination of LIDAR with camera backup for extra safety. An IR camera that sees through fog and in pitch darkness that is.

@fabischn90 5 жыл бұрын

LIDAR is better for depth resolution than stereoscopic photogrammetry. Sensor fusion wouldn't be and issue since the sensors and camera are static relative to each other

Nice presentation, but the real question is what happens when multiple lidars interfere with one another. The chances are low because of the time scales, but if there's a sufficient number of self-driving cars, there's got to be lidar pulse sync at some point between 2 or more cars.

LiDAR is not the only solution to self-driving. It has a lot of advantages, but also just as many disadvantages. The sensors are very expensive. Resolving the detailed features of objects in front of it is not very precise from off-the-shelf low-res hardware which a lot of these cars are equipped with. Plus, the current transportation infrastructure is created for visual perception, because it's driven by people who use visual perception to navigate vehicles; there is something to be said for a solution that uses visual data to navigate over LiDAR.
