DJI Zenmuse L1 Lidar+RGB Surverying Solution

The DJI Zenmuse L1 is an integrated LiDAR + RGB photogrammetry payload designed for high-precision 3D surveying and mapping. Built for the Matrice 300 RTK drone, it combines a Livox LiDAR sensor, a 20MP RGB camera, and a high-accuracy IMU to deliver centimeter-level 3D point clouds with real-time georeferencing. Ideal for topographic mapping, forestry, urban planning, and infrastructure inspection, the L1 streamlines data collection with efficiency and professional-grade accuracy.
