Overview
The DJI Zenmuse L2 is a high-performance LiDAR payload for the DJI Matrice 350 RTK, designed for rapid 3D surveying, topographic mapping, and terrain modelling. Combining a LiDAR module with an integrated 4/3 CMOS RGB camera, the L2 captures colourised point clouds that deliver both geometric accuracy and visual context — enabling surveyors and engineers to produce detailed 3D models, digital elevation models, and cross-section profiles.
The L2 features a repetitive scanning rate of 240,000 points per second with up to 5 returns per pulse, enabling penetration through vegetation canopy for bare-earth surface modelling. Its detection range extends to 250 m (at 80% reflectivity) with a ranging accuracy of ±2 cm at 150 m. Combined with the M350 RTK's centimetre-level RTK positioning, the L2 achieves absolute horizontal accuracy of 4 cm and vertical accuracy of 2.5 cm — meeting the requirements of most engineering and cadastral survey applications.
The L2's integrated 20 MP RGB camera supports true-colour point cloud generation for photorealistic 3D models and orthophotos. It supports multiple scanning modes including repetitive, non-repetitive, and line patterns optimised for different terrain types. Post-processing is handled in DJI Terra, which generates point clouds, DEMs, DSMs, contour lines, and 3D mesh models from L2 data.
