Rating: 4.0; Vote: 1
Its 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 thatll 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.

When it snows. nothing goes. and when these self driving cars get into accidents, who is going to be legally responsible? This technology is never going to take over as it cannot do certain things like work in snow. When the sensors are covered with snow or ice, my adaptive cruise does not work. The auto wipers do not work. The bright light auto control does not work. The lane detection warnings do not work. Heavy rain also has its effects rendering much of this supposed advanced technology worthless.

So the proposed LIDAR system w be sim to phased array radar, wicked. Read in a few sites they're trying to make phased array much smaller as well as SAR (Synthetic Aperture Radar) for sim applications as well as a wearable vision system for ppl w vision issues, proposed for yrs down the road and inspired by the visor on the Star Trek Next Gen character Geordi LaForge's visor. Gotta love remote sensing tech!

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.

My English is bad, so. hope you guys can understand my meaning,
I have a question, if one super short laser into the another LIDAR system will have problem?

Collecting cloud of several million precisely positioned 3D points is kind of easy. Figuring out the actual object from that cloud, now THAT is a challenge!

All you really had to show was a car and a bunch of people literally burning in a big fire because that is exactly what happens.

For the same reasons and the cost Tesla, leading in self driving, is NOT using LIDAR but radar and camera footage combined
