How do self-driving cars “see”? - Sajan Saini

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.

Ted-Ed always coming with the answers to question I ask in my head but never say out loud

[stormysamreen]

Self-driving car: "sees" a pedestrian with a club
Self-driving car: "Why do i hear boss music?"

Thank you for shortening down to 5 minutes almost the entire course of MS Optoelectronic i took this year. Amazing how concepts such as a MZ modulator and integrated photonics can be explained in such an easy way.

Ted Ed is phenomenal. I’m constantly impressed and thankful for your work in making knowledge so accessible and digestible. I’ve learned so much from watching this channel, and your videos have prompted me to delve deeper into different topics I don’t think I ever would’ve gotten the opportunity to. Thanks for all your hard work❤️

*A better question*
How does a Tow Truck drive backwards at 80 km/h and becomes a secret agent

Ted-Ed describes things with so much detail in a way that no other science youtube channel does. Thank you for that. You are an amazing teacher and educator

Ted-Ed always answers my everyday questions. What a splendid YouTube channel!

I have seen CARS movie enough times to believe cars have eyes in their windows and the ventilation as their mouth

I love the tone of this Narrator the most, I could listen to him all day

[abderraoufkhodja]

Great job, you have done a great deal of emphasis on the sensor part of a self-driving car. However, you did not mention at all the decision-making mechanism, which is in my opinion, the real challenge of self-driving, I think that video on deep learning would be highly appreciated.

Person who manufactured the car: "Am I a joke to you?"

[makarlock]

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.

As someone who doesn't drive for health reasons and wants a fully autonomous vehicle in the future, this was really informative on how self-driving cars actually work! Thanks Ted-Ed :)

[avramdanielenriquez]

What a great and simple explanation of solid state lidar, I am impressed!

[vjazz]

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

[TheRock-zozl]

Another gem from TED after long time 💎❤️

keep up the good work, thanks for explaining complex things simply,

This channel deserves more likes and views.

Forever answering questions I never asked but am fascinated by the answer
