DJI Matrice 350 RTK (L1 Sensor)
Category
The DJI Matrice 350 RTK equipped with the Zenmuse L1 payload is an enterprise-grade UAV-based LiDAR system designed for high-precision 3D mapping, terrain modelling, and geospatial data acquisition.
It integrates LiDAR scanning, high-accuracy RTK GNSS positioning, inertial measurement, and an RGB mapping camera into a single platform, enabling the capture of dense, georeferenced point cloud datasets with centimetre-level accuracy.
The system combines LiDAR sensing with RTK positioning and IMU-based trajectory correction to deliver accurate spatial datasets, even in challenging environments such as dense vegetation or complex terrain.
It is particularly suited for applications where conventional photogrammetry is limited, including canopy penetration, corridor mapping, and detailed terrain modelling.
