  • 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.
    Lesson by Sajan Saini, directed by Artrake Studio.

      @@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.

    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.
