LiDAR

 

LiDAR stands for Light Detection and Ranging. It is a remote sensing technology that uses laser light to measure distances and create 3D maps of objects and environments.

In a LiDAR system, a laser emits pulses of light, which travel through the air and bounce off objects in the environment. The LiDAR system then detects the reflected light and measures the time it takes for the light to return to the sensor. By repeating this process many times per second, LiDAR systems can create a 3D map of the environment, with each point in the map representing a location and distance.

LiDAR is used in a variety of applications, including autonomous vehicles, robotics, surveying and mapping, and environmental monitoring. In autonomous vehicles, LiDAR is used to create a 3D map of the environment, which helps the vehicle to detect and avoid obstacles, pedestrians, and other vehicles. In robotics, LiDAR can be used for navigation and obstacle avoidance. In surveying and mapping, LiDAR can be used to create high-resolution maps of terrain and structures. And in environmental monitoring, LiDAR can be used to measure forest biomass, track changes in coastal topography, and monitor air quality.

LiDAR technology has become increasingly popular in recent years, as the cost of the technology has decreased and the demand for 3D mapping and sensing has increased.
