Boosted Intelligence and Operational Efficiency

Hardware Performance Redefined

The Zenmuse L3 integrates 1535 nm long-range LiDAR, dual 100 MP RGB cameras, and a high-precision POS system into a compact three-axis gimbal, delivering exceptional surveying performance in a small, lightweight package.

950m Long-Range LiDAR

Long Range, Wide Coverage

The Zenmuse L3 offers an impressive 950 m detection range, even on low-reflectivity objects (as little as 10%), ensuring reliable performance in bright ambient light. Its adjustable pulse rate optimises power output for various scenarios, supporting typical flight altitudes of 300–500 m. This extends single-flight coverage, boosting mapping efficiency for large-scale surveying projects.

Small Spot, High Energy

With a reduced beam divergence of just 0.25 mrad (1/e²), the Zenmuse L3 produces a laser spot approximately one-fifth the size of the Zenmuse L2. This high precision captures fine details—like power lines and tree branches—with exceptional clarity. The concentrated energy also improves vegetation penetration, generating denser ground points for accurate terrain modelling in complex environments.

High Pulse Rate, Multiple Returns

The Zenmuse L3 delivers a maximum pulse frequency of 2 million pulses per second and supports up to 16 returns, enabling exceptional spatial reconstruction. Its adaptable settings allow operators to adjust point cloud density and penetration for precise mapping or surveying in complex, vegetated environments.

Scanning Modes

The Zenmuse L3 offers three specialised scanning modes to suit a variety of operational scenarios:

Linear Mode: Provides uniform point cloud distribution, ideal for high-accuracy terrain mapping.
Star-Shaped Mode: Balances multi-angle scanning with strong penetration, perfect for surveying forests or dense urban areas.
Non-Repetitive Mode: Maximises scan angles and coverage, capturing detailed structures such as power lines and complex infrastructure.

DUAL 100MP RGB MAPPING CAMERA SYSTEM

Dual 100MP RGB Mapping Cameras

Powered by dual 100MP 4/3 CMOS RGB sensors and a mechanical shutter, the Zenmuse L3 delivers a major boost in mapping accuracy and imaging efficiency. Through pixel binning, it outputs an effective 25MP resolution with larger pixels, providing enhanced colour fidelity and sharp, clear imagery—even in challenging low-light environments.

107° Ultra-Wide FOV

With a wide 107° horizontal field of view (FOV), the Zenmuse L3’s dual RGB mapping cameras capture more terrain in every frame. This broad perspective enables efficient collection of both Digital Orthophoto Maps (DOM) and Digital Elevation Models (DEM) in a single flight—even with just 20% LiDAR side overlap—significantly increasing overall mapping efficiency.

The Zenmuse L3 sets a new benchmark for aerial surveying, delivering superior point cloud accuracy, enhanced RGB clarity, and significantly faster data acquisition.
Optimised for the DJI Matrice 400, it enables up to 10km² of coverage per flight and as much as 100km² per day, providing a streamlined, unified workflow for high-accuracy, large-scale mapping projects.

HIGH ACCURACY

Proprietary High-Precision System
The enhanced high-precision POS system delivers outstanding orientation accuracy, achieving 0.02° heading and 0.01° pitch precision after post-processing. Paired with a self-developed LiDAR module offering 5mm ranging repeatability at 150m and microsecond-level time synchronisation, the Zenmuse L3 ensures reliable, survey-grade results. Each unit undergoes strict factory calibration to maintain consistent performance.

LiDAR Data Accuracy
The Zenmuse L3 delivers outstanding vertical accuracy at multiple flight altitudes—better than 3 cm at 120 m, 5 cm at 300 m, and 10 cm at 500 m—meeting the demands of 1:500, 1:1000, and 1:2000 scale mapping projects with ease. It also generates a point cloud with half the thickness of the Zenmuse L2, providing cleaner, more precise data for detailed analysis and high-accuracy surveying applications.

Photogrammetric Accuracy
With dual 100MP RGB mapping cameras, the Zenmuse L3 captures high-detail imagery, achieving a 3 cm GSD even from 300 m flight altitudes. Real-time position synchronisation further enhances accuracy, enabling precise photogrammetric mapping without Ground Control Points (GCPs) and substantially streamlining field and processing workflows.

High Penetration & High Ground Point Density
With its reduced laser spot size and increased single-pulse energy, the Zenmuse L3 achieves superior vegetation penetration and significantly higher ground point density. This capability results in more complete terrain data, ensuring exceptional surface fitting accuracy and robust terrain reconstruction across challenging, vegetated environments.

High Efficiency — Up to 100 km² Per Day
Paired with the DJI Matrice 400, the Zenmuse L3 sets a new standard for productivity. A single flight at 300 m altitude can capture up to 10 km² of data, enabling total daily coverage of up to 100 km² for large-scale surveying and mapping projects.

Multiple Deliverables in One Flight
The system simultaneously collects LiDAR and RGB data, allowing you to generate a wide range of outputs—including Digital Elevation Models (DEM), Digital Orthophoto Maps (DOM), and additional geospatial deliverables—all from a single mission.
