Today, the technology of ground and airborne laser scanning is actively used and developed all over the world. The result of laser scanning is a dense point cloud. Until recently, airborne laser scanning was carried out using manned aircrafts or UAVs with high payload capacity. However, with the advancement of technology, weight and dimensions of laser scanners made it possible to integrate them into UAVs with a maximum takeoff weight of up to 30 kg.
The main feature of the airborne laser scanning is its result consisting of laser point cloud, the position accuracy is determined by combining the data of the exterior orientation (dual-frequency, dual-system GNSS receiver) and interior orientation (high-precision inertial system). As a result, the accuracy of the airborne laser scanning does not exceed a few centimeters.
Unmanned Systems Group has completed the development of Supercam S350 UAS with an integrated laser scanner, as well as, optionally, a high-resolution digital photo camera. The operational height is up to 200 m.
The existing laser scanners can also be installed on the multi-rotor Supercam X6M2 UAV. The operational height is up to 80 m.
Airborne laser scanning can be used effectively in the mining, oil and gas industry, power line inspection, mine surveying, and obtaining terrain data even covered with vegetation
