A LiDAR drone is a drone equipped with LiDAR technology. LiDAR is a remote sensing technique that stands for Light Detection and Ranging. It utilizes pulsed infrared laser beams to measure distances to the Earth’s surface. This information, along with information collected by the airborne system, can generate a 3D model the terrain. The LiDAR system does not provide photographic details, instead it creates a point cloud with the data that has been returned from the objects on the ground.
LiDAR technology is a relatively new technology, created in the 1960’s just after lasers were developed. It was used during the Apollo 15 mission in 1971, and then was used for commercial purposes in the 1980’s after GPS became available for public use.
These drones are used in a range of applications, such as surveying, topographical mapping, and creating 3D models of buildings and structures.
