LiDAR system for DJI Matrice 400, Matrice 350 RTK and Matrice 300 RTK. 905 nm LiDAR, detection range up to 450 m, up to 5 returns and a 4/3″ 20 MP RGB camera. Accuracy of 5 cm horizontal and 4 cm vertical.
DJI Zenmuse L2 — a LiDAR system for aerial surveying. It combines a LiDAR, a high-precision IMU and a 4/3″ RGB mapping camera.
The LiDAR detects objects at up to 450 m (50% reflectivity), supports up to 5 returns and generates up to 1.2 million points per second. The point cloud is colorized in real time, and the 20 MP camera with mechanical shutter provides images for photogrammetry. System accuracy is 5 cm horizontal and 4 cm vertical at 150 m.
Compatible with Matrice 400, Matrice 350 RTK and Matrice 300 RTK; data is processed in DJI Terra. Suitable for topographic surveys, terrain modeling, power line inspection, construction and forestry.
Key features
Range up to 450 m — at 50% reflectivity.
Up to 5 returns — terrain capture under vegetation.
Up to 1.2 million pts/s — fast point cloud generation.
4/3″ RGB camera, 20 MP — mechanical shutter and point cloud colorization.
5 / 4 cm accuracy — horizontal and vertical at 150 m.
450m @50% reflectivity, 0klx 250m @10% reflectivity, 100klxTypical data. Measured using a flat subject with a size larger than the laser beam diameter, perpendicular angle of incidence, and an atmospheric visibility of 23 km. In low-light environments, the laser beams can achieve the optimal detection range. If a laser beam hits more than one subject, the total laser transmitter power is split, and the achievable range is reduced. The maximum detection range is 500 m.
Point Cloud Rate
Single return: max. 240,000 pts/s Multiple returns: max. 1,200,000 pts/s
System Accuracy
Horizontal: 5 cm @ 150 m Vertical: 4 cm @ 150 mMeasured under the following conditions in a DJI laboratory environment: Zenmuse L2 mounted on a Matrice 350 RTK and powered up. Using DJI Pilot 2’s Area Route to plan the flight route (with Calibrate IMU enabled). Using repetitive scanning with the RTK in the FIX status. The relative altitude was set to 150 m, flight speed to 15 m/s, gimbal pitch to -90°, and each straight segment of the flight route was less than 1500 m. The field contained objects with obvious angular features, and used exposed hard ground check points that conformed to the diffuse reflection model. DJI Terra was used for post-processing with Optimize Point Cloud Accuracy enabled. Under the same conditions with Optimize Point Cloud Accuracy not enabled, the vertical accuracy is 4 cm and the horizontal accuracy is 8 cm.

Ranging Accuracy (RMS 1σ)
2 cm @ 150 mMeasured in an environment of 25° C (77° F) with a subject of 80% reflectivity at a distance of 150 m. The actual environment may differ from the testing environment. The figure listed is for reference only.
Horizontal 0.2 mrad, Vertical 0.6 mradMeasured at full width at half maximum (FWHM) conditions. 0.6 mrad signifies that for every 100m increase in distance, the diameter of the laser beam expands by 6 cm.
