ENHANCED INTELLIGENCE AND EFFICIENCY

Hardware Performance Redefined

The Zenmuse L3 combines 1535nm wave-length long-range LiDAR, dual 100MP RGB cameras, and a high-precision POS system into a compact three-axis gimbal, delivering performance that defies its size.

950m Long-Range LiDAR

Long Range, Wide Coverage

The Zenmuse L3 achieves an impressive 950m detection range—even on objects with just 10% reflectivity—ensuring reliable performance under bright ambient light. With an adjustable pulse rate to optimise power output for diverse scenarios, the L3 supports typical flight altitudes of 300 to 500m. This capability significantly expands single-flight coverage, maximising mapping efficiency across large areas.

Small Spot, High Energy

Featuring a reduced beam divergence of just 0.25 mrad (1/e²), the Zenmuse L3 creates a laser spot size roughly one-fifth that of the Zenmuse L2. This precision allows it to capture fine details, such as power lines and tree branches, with exceptional clarity. Furthermore, the concentrated energy density enhances vegetation penetration, delivering denser ground points for accurate terrain reconstruction in complex environments.

High Pulse Rate, Multiple Returns

Delivering a maximum pulse emission frequency of 2 million pulses per second and supporting up to 16 returns, the Zenmuse L3 ensures exceptional spatial reconstruction. This power is fully adaptable; operators can adjust point cloud density and penetration capabilities to match the specific demands of the mission, from high-precision mapping to surveying complex, vegetated environments.

Scanning Modes

The Zenmuse L3 adapts to diverse operational scenarios with three specialised scanning modes:

Linear Mode: Delivers uniform point cloud distribution, making it the ideal choice for high-accuracy terrain mapping.
Star-Shaped Mode: Offers a balance of multi-angle scanning and penetration power, perfect for surveying forests or dense urban environments.
Non-Repetitive Mode: Maximises scan angles and coverage, ensuring detailed capture of complex structures like power lines.

DUAL 100MP RGB MAPPING CAMERA SYSTEM

Dual 100MP RGB Mapping Cameras

Equipped with dual 100MP 4/3 CMOS RGB sensors and a mechanical shutter, the Zenmuse L3 significantly elevates both accuracy and efficiency. The system utilises pixel binning to deliver an effective 25MP resolution with larger individual pixels, ensuring superior colour reproduction and image clarity even in low-light conditions.

107° Ultra-Wide FOV

With an expansive 107° horizontal field of view (FOV), the dual RGB mapping cameras maximise coverage in every shot. This wide perspective allows operators to capture data for both Digital Orthophoto Maps (DOM) and Digital Elevation Models (DEM) in a single flight—even with a minimal 20% LiDAR side overlap—drastically boosting operational efficiency.

The Zenmuse L3 sets a new benchmark for aerial surveying by enhancing point cloud and RGB precision while redefining operational speed.

Optimised for the DJI Matrice 400, this system enables up to 10km² of coverage in a single flight and up to 100km² per day. This integration ensures high-accuracy results for large-scale projects through a unified, efficient workflow.

HIGH ACCURACY

Proprietary High-Precision System

The upgraded high-precision POS system ensures exceptional orientation accuracy, achieving 0.02° heading and 0.01° pitch precision (post-processed). Complementing this, the self-developed LiDAR module delivers a ranging repeatability of 5mm at 150m, supported by microsecond-level time synchronisation. To guarantee consistent, survey-grade performance, every unit undergoes rigorous factory calibration.

LiDAR Data Accuracy

The Zenmuse L3 maintains exceptional vertical accuracy across various altitudes—better than 3cm at 120m, 5cm at 300 m, and 10cm at 500m. These capabilities allow it to easily satisfy requirements for 1:500, 1:1000, and 1:2000 scale mapping projects. Additionally, the L3 produces a point cloud thickness just half that of the Zenmuse L2, delivering cleaner data for advanced analysis and high-precision applications.

High Penetration

High Ground Point Density

Combining a smaller laser spot with higher single-pulse energy, the Zenmuse L3 offers superior penetration through vegetation. This allows for the capture of a denser, more complete array of ground points, ensuring exceptional data integrity for precise surface fitting and terrain reconstruction.

Photogrammetric Accuracy

Powered by dual 100MP RGB mapping cameras, the Zenmuse L3 captures exceptional detail, achieving a Ground Sample Distance (GSD) of 3cm even at flight altitudes of 300m. Furthermore, real-time position synchronisation allows for high-precision mapping without the need for Ground Control Points (GCPs), significantly streamlining the surveying workflow.

High Efficiency

Up to 100km² per Day

When integrated with the DJI Matrice 400, the Zenmuse L3 delivers outstanding operational efficiency. A single flight at 300m altitude covers up to 10km², allowing operators to achieve a daily mapping capacity of up to 100km².

Multiple Deliverables in a Single Flight

In a single mission, the system records both LiDAR and RGB data to produce diverse mapping deliverables, such as Digital Elevation Models (DEM), Digital Orthophoto Maps (DOM), and more.
