DJI Zenmuse L3 (EU) SP Plus

DJI's next-generation high-accuracy aerial LiDAR system features a long-range LiDAR capable of reaching up to 950 m even on objects with just 10% reflectivity. Dual 100MP RGB mapping cameras and a high-precision POS system accelerate geospatial data acquisition, enabling daily coverage of up to 100 km².

Hardware Performance Redefined

Zenmuse L3 integrates a 1535nm long-range LiDAR, dual 100MP RGB mapping cameras, a high-precision POS system, and a three-axis gimbal, all within a compact device, delivering unprecedented performance for its size.

1535nm Long-Range LiDAR

Long Range, Wide Coverage

Zenmuse L3 achieves a maximum detection range of 950 m at a pulse rate of 100 kHz, tested under 100 klx ambient light and on objects with 10% reflectivity. The adjustable pulse rate allows for flexible power output and optimal adaptation to different operational scenarios. Typical flight altitudes of 300 to 500 m significantly expand single-flight coverage and boost mapping efficiency.

Small Spot, High Energy

With a laser beam divergence of just 0.25 mrad (1/e²), the spot size at the same range is about one-fifth that of Zenmuse L2, enabling detection of smaller objects such as power lines and branches. Higher energy density results in stronger penetration capability, significantly increasing ground point density beneath vegetation and enabling high-accuracy reconstruction of complex terrains and structures.

High Pulse Rate, Multiple Returns

With maximum laser pulse emission frequency of 2 million pulses per second and support for up to 16 returns, Zenmuse L3 delivers highly accurate spatial reconstruction. Point cloud density and penetration capability can be adjusted to fit needs from high-accuracy mapping to complex environments.

Scanning Modes

Supports Linear, Star-Shaped, and Non-Repetitive scanning modes for different operational scenarios:

• Linear: Achieves more consistent point cloud distribution, ideal for high-accuracy terrain mapping.

• Star-Shaped: Balances accuracy with multiple scan angles and penetration capability, well-suited for forests or dense urban environments.

• Non-Repetitive: Provides multiple scan angles and broader coverage, optimized for power line inspections and other complex structural surveys.

Dual 100MP RGB Mapping Camera System

Dual 100MP RGB Mapping Cameras

Equipped with dual 100MP 4/3 CMOS RGB sensors and a mechanical shutter, Zenmuse L3 delivers significantly enhanced accuracy and efficiency. Pixel binning supports an effective 25MP resolution with larger pixel size, producing superior color reproduction even under poor lighting conditions.

107° Ultra-Wide FOV

The dual RGB mapping cameras provide a horizontal field of view (FOV) of up to 107°, allowing each capture to cover a broader area. Even with a 20% LiDAR side overlap ratio, you can capture data for both digital orthophoto maps (DOM) and digital elevation models (DEM) in a single flight, thereby greatly improving operational efficiency.

Accuracy Meets Efficiency

Zenmuse L3 delivers significant improvements in both point cloud and RGB accuracy, while raising efficiency to new heights. Paired with DJI Matrice 400, a single flight can cover up to 10 km², enabling up to 100 km² of high-accuracy mapping per day. Large-area, high-accuracy results are delivered in a seamless workflow.

High Accuracy

Proprietary High-Precision System

The upgraded high-precision POS system achieves heading accuracy of 0.02° and pitch accuracy of 0.01° (post-processed, 1σ). The self-developed LiDAR delivers ranging repeatability of 5 mm at 150 m (1σ) and supports microsecond-level time synchronization. Each unit undergoes rigorous factory calibration to ensure consistently reliable survey results.

LiDAR Data Accuracy

Vertical accuracy is better than 3 cm at 120m altitude, better than 5 cm at 300 m, and better than 10 cm at 500 m, easily supporting mapping projects at 1:500, 1:1000, and 1:2000 scales. The point cloud thickness produced by Zenmuse L3 is only half that of Zenmuse L2, supporting advanced analysis and high-accuracy applications.

Photogrammetric Accuracy

With dual 100MP RGB mapping cameras, Zenmuse L3 achieves a ground sample distance (GSD) of 3 cm even at a 300m flight altitude

. Real-time position synchronization enables operation without ground control points (GCPs), ensuring high-quality imagery for precise mapping.

High Penetration

High Ground Point Density

With a smaller laser spot and higher single-pulse energy, Zenmuse L3 offers superior penetration capability. In terrain mapping and similar applications, it captures more ground points with greater completeness, significantly improving the accuracy and integrity of terrain data for precise surface fitting and reconstruction.

High Efficiency

Up to 100 km per Day

When mounted on DJI Matrice 400, Zenmuse L3 delivers outstanding efficiency. At a flight altitude of 300 m, a single flight can cover up to 10 km2, enabling up to 100 km2 of daily coverage".

Multiple Deliverables in a Single Flight

Simultaneusly captures LiDAR and RGB dana to generate a range of mapping Products from a single flight, including DEM, DOM, and more.

End-To-End Solution

Zenmuse L3 seamlessly integrates with DJI's ecosystem to deliver an end-to-end mapping solution. From data acquisition and processing to application, this unified workflow is simpler to operate and easier to master than traditional multi-platform setups, helping users efficiently complete a wide range of mapping tasks.

Delivers a complete workflow covering data capture, processing, and application.

Data Security

Zenmuse L3 supports CFexpres memory card encryption, enabling secure protection of stored data and preventing unauthorized access or data theft. Matrice 400 offers one-click log clearing and AES-256 encryption for video transmission, further ensuring data confidentiality.
