UAV-mounted sensors differ significantly from high-altitude manned aircraft systems. They typically fly at lower altitudes, produce much denser point clouds, and often utilize lighter, more cost-effective IMU (Inertial Measurement Unit) systems that may require more rigorous calibration and trajectory correction.
| Parameter | UAV Setting (Terrasolid) | Why | | :--- | :--- | :--- | | | 40-80 m | UAV swaths are narrow; a smaller value may misclassify ground along sloped roofs. | | Ground Angle | 78-88° (steep) | UAV points have lower vertical accuracy; flatter angle (e.g., 70°) will erode ditches. | | Max Terrain Deviation | 0.5-1.0 m | Accounts for micro-topography visible to UAVs. | | Seed Points Distance | 10-25 m | UAV point density allows tighter seeds than airplane LiDAR (50m). | terrasolid uav
The flagship capability of Terrasolid is its classification engine. UAV data often contains significant noise due to multi-path returns or moving objects (birds, vehicles). | | Ground Angle | 78-88° (steep) |
