DJI Zenmuse L2

The Zenmuse L2 is a drone-mounted LiDAR payload that integrates a frame-based LiDAR scanner, a high-accuracy IMU, and a 4/3″ 20 MP RGB mapping camera on a 3-axis gimbal. It’s designed for precise 3D data capture and aerial surveying.

The system supports up to 240,000 points per second for single returns and up to 1,200,000 points per second in multi-return mode, with a maximum of 5 returns per pulse depending on the environment.

With proper RTK or PPK setup, the L2 can achieve horizontal accuracy of approximately 5 cm and vertical accuracy of approximately 4 cm under typical flight conditions.

The L2 can detect objects up to around 450 m away under optimal conditions. The laser spot size is approximately 4 × 12 cm at 100 m, offering improved detail and accuracy over previous models.

Depending on overlap, flight speed and height, the L2 can cover up to approximately 2.5 km² in a single flight under standard survey conditions.

The RGB camera features a 4/3″ CMOS sensor with 20 MP resolution, 24 mm equivalent focal length, f/2.8–f/11 aperture, mechanical shutter, and a minimum photo interval of about 0.7 seconds.

Yes, the RGB camera can be used separately for mapping and inspection tasks, or to colourise point clouds post-processing.

The L2’s self-developed IMU provides real-time yaw accuracy of about 0.2°, pitch and roll of about 0.05°. Post-processing can further improve these to approximately 0.05° yaw and 0.025° pitch/roll.

The L2 is compatible with the Matrice 350 RTK and Matrice 300 RTK drones, using the DJI RC Plus controller. Always confirm firmware compatibility before use.

The L2 handles a wide range of lighting and terrain conditions, including forest canopy penetration and low-reflectivity surfaces, thanks to its high return rate and multi-echo capabilities.

Yes, with proper RTK or PPK setup, survey-grade results are possible. However, ground check points are still advised to verify accuracy whe
