How is LiDAR remote sensing used for Autonomous vehicles?

Показать описание

Self-driving cars are now a reality. Take a look around. Cars are already driving themselves on the roads of California, Texas, Arizona, Washington, Pennsylvania, Michigan and many more cities. Though, currently they are restricted to specific test areas and driving conditions. But how exactly do they work?

Just like humans they also face issues of traffic congestion, rash driving, potholes, trees and other obstacles on the road. But again…How do they change lane, keep a safe distance from other vehicles passing by and how do they identify roadblocks.

Let’s take a closer look at how they handle such situations smoothly?

You might have noticed a rotating device installed on top of this autonomous vehicle. Sometimes these devices are mounted on the bonnet. This device is called LiDAR. It acts as the eye of self-driving vehicles providing a 360-degree view of its surroundings in order to enable safe driving.

Continuously rotating LiDAR system sends thousands of laser pulses every second. These pulses collide with the various objects around the vehicle and reflect back the signals. These light reflections are then used to create a 3D point cloud. An onboard computer records each laser’s reflection point and translates this rapidly updating point cloud… into an animated 3D representation.

Stop showing Tesla's UI when talking about Lidar. They use radar not lidar.

FYI Tesla does NOT use LIDAR. They use 8 exterior cameras, long range radar and 12 ultrasonic sensors. And even though they have the capability of full autonomy they aren't aloud to turn it on just yet.

Ultrasound can send signal few miles ahead to detect traffic and calibrate exact return signal base on driver request of distance range so alternate route recommend base on instant scan so driver can be aware even does not know how to use GPS

I wish the part about avoiding potholes or making them smoother was true…

My ex is using fleet management to mess up my car when I drive .It won't accelerate but only when I try to drive to one specific place .What technology is that ? Anyone ?
