DJI Zenmuse L3 Long-Range LiDAR System with Highest Accuracy

The DJI Zenmuse L3 is a state-of-the-art, next-generation aerial LiDAR system delivering exceptional range and accuracy. Its 1535 nm LiDAR sensor reaches up to 950 meters even on targets with only 10% reflectivity. Dual 100-megapixel RGB mapping cameras and a high-precision Position and Orientation System (POS) accelerate geospatial data acquisition, enabling daily coverage of up to 100 km².

1535 nm Long-Range LiDAR: Extended Range, Broad Coverage

The Zenmuse L3 achieves a maximum detection range of 950 meters at 100 kHz pulse frequency under 100 klx ambient light and 10% reflectivity. The adjustable pulse frequency provides flexible power output, optimizing performance for various operational scenarios. Typical flight altitudes between 300 and 500 meters increase coverage per flight and significantly improve mapping efficiency.

Small Measurement Point, High Pulse Energy

With a laser beam divergence of only 0.25 mrad (1/e²), the laser footprint diameter at distance is about one-fifth that of the Zenmuse L2. This enables clear detection of smaller objects such as power lines or branches. The higher energy density improves penetration, increases ground point density, and allows precise reconstruction of complex terrain.

High Pulse Repetition Rate, Multiple Returns

With up to 2 million pulses per second and support for up to 16 returns, the Zenmuse L3 delivers accurate 3D spatial reconstructions. Point density and penetration level can be flexibly adapted to meet specific application requirements.

Flexible Scanning Modes

The system supports linear, star-shaped, and non-repetitive scanning modes for various applications: 

    · Linear: uniform point cloud distribution for precise terrain modeling

    · Star-shaped: balances accuracy with high penetration, ideal for forests or urban areas

    · Non-repetitive: wide scan angle and extensive coverage, optimized for powerline and structural inspections

Dual 100 MP RGB Camera System

Equipped with two 100 MP 4/3 CMOS sensors and mechanical shutters, the L3 significantly improves accuracy and efficiency. Pixel binning supports an effective resolution of 25 MP with larger pixels, ensuring vivid colors even in low-light conditions.

107° Ultra-Wide Field of View

The dual RGB cameras offer up to 107° horizontal field of view, capturing a larger area per image. Even with 20% LiDAR overlap, digital orthophoto maps (DOM) and digital elevation models (DEM) can be acquired simultaneously in a single flight, greatly boosting productivity.

Accuracy Meets Efficiency

The enhanced Position and Orientation System (POS) achieves post-processing accuracy of 0.02° yaw and 0.01° pitch. The LiDAR offers ranging repeatability of 5 mm at 150 m and microsecond timing for highly precise results. Vertical accuracy is under 3 cm at 120 m altitude, under 5 cm at 300 m, and under 10 cm at 500 m suitable for mapping scales from 1:500 to 1:2000. With a ground sample distance (GSD) of 3 cm at 300 m altitude, the L3 enables precise mapping even without ground control points (GCP).

High Point Density, Strong Penetration & High Efficiency

Thanks to smaller laser footprints and higher pulse energy, the L3 captures significantly more ground points beneath vegetation, enhancing detail, accuracy, and model completeness. Combined with the DJI Matrice 400, the Zenmuse L3 covers up to 10 km² per flight and up to 100 km² daily. Multiple data types, such as point clouds, orthophotos, and 3D models, can be collected in a single mission.

DJI Terra Integration: PPK, LiDAR Gaussian Splatting & Fusion-Based Modeling

DJI Terra provides integrated PPK (Post-Processed Kinematic) data processing for centimeter-level positioning accuracy, even without RTK availability. The software supports local PPK processing for RGB imagery and LiDAR data. Advanced Gaussian Splatting technology produces highly detailed and realistic 3D models. Fusion of LiDAR and RGB data in a single dataset enables simultaneous generation of high-accuracy point clouds, 2D maps, and 3D mesh models. This data fusion approach improves model completeness, especially for complex structures, meeting the needs of energy, transportation, and infrastructure sectors.

Integrated End-to-End Solution

The L3 works seamlessly within the DJI ecosystem from data capture and PPK post-processing in DJI Terra to cloud analysis in DJI FlightHub 2. Real-time point cloud previews, live measurements, and flexible split-screen views increase mission efficiency and safety.

Secure Data Processing

CFexpress card encryption and AES-256 video transmission encryption protect sensitive data. The Matrice 400 also supports one-click log clearing for added security.

Typical Applications

Topographic surveying, civil and geotechnical engineering, geological studies and hazard mapping, forestry and vegetation analysis, energy and powerline inspections, mining and infrastructure surveying.
