LiDAR Sensors In Autonomous Vehicles: What Is Their Use And Importance?

Artificial Intelligence is being made possible in several domains thanks in large part to sensor-based technology. One of the most exciting sensor-based technologies utilized is LiDAR sensors in autonomous vehicles. Such autonomous vehicles have to become aware of their surroundings and travel safely without any chance of collision.

LiDAR sensors in autonomous vehicles help the vehicles recognize objects in-depth. We will now talk about how LiDAR sensors in autonomous vehicles work, and why it is important for autonomous or self-driving vehicles.

How Do LiDAR Sensors In Autonomous Vehicles Work?

When viewed from a distance, LIDAR performs very similarly to sonar systems, which produce sound waves that are directed in all directions until they come into touch with an object, at which point they resonate and return to their source. Then, using the time it took for the echo to return and the established speed of sound, the distance to that item is computed.

The speed of light, which is more than 1,000,000 times faster than the speed of sound, also applies to how LiDAR systems work. They thereby transmit and receive data from hundreds of thousands of laser pulses every second rather than creating sound waves. Each laser’s reflection point is recorded by an onboard computer, and this quickly updating “point cloud” is then transformed into an animated 3D depiction of the environment.

The scanner, laser, and GPS receiver are the three primary parts of a LiDAR device. Adding to the list of essential parts for data collection and processing are the photodetector and optics. Nowadays, the majority of public and private entities collect LiDAR data using airplanes, autonomous aircraft, and helicopters.

Use Of LIDAR Sensors In Autonomous Vehicles

Radar has long been used in the vehicle industry to automatically regulate speed, brakes, and safety systems in reaction to abrupt changes in traffic circumstances. LIDAR is now being included by automakers in ADAS to help drivers better understand the dynamic settings in which their vehicles operate.

Using a variety of valuable statistics from the integration of automotive platforms, ADAS systems are able to perform hundreds of precisely calculated driving decisions every minute. We recognize this technology as a crucial element in creating new driver-aid features that can direct the development of fully autonomous self-driving automobiles with safe and secure travel.
