UAV laser scanner surveying
Overview… UAV-mounted small Lider system Specialized for terrain measurement Rich LaserScanner specifications Rate: 40,000 points/second, Distance: Reflectance 30% to 250m, Field of view: 90° Distance measurement accuracy: 6mm at 50m, 20mm at 150m Equipped with class-leading INS* Horizontal accuracy: 10mm, vertical accuracy: 20mm, Attitude accuracy: Pitch/Roll 0.015° Characteristics… Why use a 3D laser scanner?! In photogrammetry, it is impossible to measure all terrain surfaces. While photogrammetry is common for UAV measurement content, photographs capture visible landscapes, so when trees are present, only the surface layer of the trees can be captured, and measurements of the ground surface cannot be performed. The Lider system uses lasers to measure the ground by passing through gaps in the trees. By directly measuring both the surface layer of the trees and the ground surface data and performing filtering, it removes the trees and creates terrain map data (DEM) necessary for civil engineering design and other applications.

Applications/Examples of results
Conventional drone surveying is photogrammetry. Does that mean it can measure terrain? In forested areas, terrain surveying using photogrammetry is impossible, no matter how advanced the technology becomes. This is where laser measurement shows its strength.
Company information
Our company is a surveying firm that conducts topographic measurements and bathymetric surveys using drones (autonomous small unmanned aerial vehicles), remote-controlled boats (autonomous unmanned survey vessels), and GNSS (GPS surveying equipment). Among the surveying methods utilizing drones, we offer rare services such as topographic measurements of wooded areas using a small laser scanner mounted on a drone, as well as drone photogrammetry that does not require ground control points. Additionally, we perform environmentally safe bathymetric surveys using small remote-controlled boats, and for GPS-based control point surveys, we can handle everything from public surveying applications to result verification. For specialized measurements, we also create three-dimensional models of tunnels and other structures using digital cameras. Consultations and estimates are provided free of charge. Please visit our website first, and feel free to consult with Apeo Giken regarding any surveying needs, including those requiring specialized techniques, as well as general surveying. We serve clients nationwide.
