Capteur lidar GDU 400

Caractéristiques principales

• Triple Echo Technology: Capable of capturing up to 720,000 points per second. The triple-return capability allows the laser to penetrate dense vegetation to map the true ground surface (DEM) beneath forest canopies.

• High-Precision Accuracy: Equipped with a professional-grade GNSS and high-precision IMU, the system delivers centimeter-level point cloud accuracy.

• Operational Efficiency: The sensor can detect objects up to 450 meters (at 80% reflectivity) and is capable of covering up to 2 square kilometers in a single flight.

• Imagerie intégrée : Features a built-in mapping camera that captures detail-rich RGB images simultaneously, allowing for the creation of “true-color” 3D point clouds.

• Conception légère : Pesée uniquement 1.07 kg, it maximizes the flight time of the S400 drone (up to ~50+ minutes depending on conditions).

Spécifications techniques

Applications courantes

• Inspection des lignes électriques : Detecting vegetation encroachment and structural sag with high-detail 3D models.

• Topographic Surveying: Generating Digital Elevation Models (DEM) in forested or rugged terrain.

• Forestry Management: Measuring tree height, canopy density, and biomass.

• Disaster Relief: Rapid 3D reconstruction of landslide areas or earthquake zones.

Note: If you were specifically looking for information on the DJI Matrice 400’s obstacle-sensing LiDAR (the internal sensor used for flight safety), that is a built-in 360° rotating LiDAR used for omnidirectional obstacle avoidance rather than mapping.
