UAV Drone Photogrammetry & LiDAR

Deploying commercial mapping drones calibrated with dual-frequency Ground Control Points (GCPs). Ideal for fast topological audits, stockpile calculation, and orthophoto compilation.

Precision Rating: Ground Sample Distance: 0.8cm/pixel, Vertical: ±15mmVerified SOB Standard

Technical Overview & Standard Operating Procedure

Aerial photogrammetry and airborne LiDAR technology enable rapid spatial data collection across massive geographic regions. By acquiring high-density point clouds from above, we produce sub-centimeter orthomosaics and digital terrain models (DTM) that pierce through vegetation layers.

Execution Methodology & Equipment Calibration

Using multi-frequency RTK mapping drones like the DJI Matrice 300 RTK paired with Zenmuse L1 LiDAR sensors, we execute automated flight paths. Physical Ground Control Points (GCPs) measured via GNSS receivers correct lens distortion and spatial drift.

Key Application Scenarios

Large-scale agricultural land mapping
Mining and quarry volume measurement
Disaster damage & river erosion assessment
Smart city 3D mesh reconstruction
