ZENMUSE L3

Zenmuse L3 is DJI’s next-generation aerial LiDAR system, featuring an exceptional ranging capability of up to 950 m, even on surfaces with only 10% reflectivity, paired with dual 100MP RGB cameras and a high-precision POS system. With a fully integrated hardware–software ecosystem, Zenmuse L3 enables large-scale geospatial data acquisition at remarkable speed—up to 100 km² per day.

Hardware Performance – Redefining Excellence

Zenmuse L3 integrates a long-range 1535 nm LiDAR, dual 100MP RGB cameras, a high-precision POS system, and a 3-axis gimbal into a compact device. Everything works together to deliver best-in-class performance.

1535 nm Long-Range LiDAR – Extended Range, Superior Coverage

950 m Ranging Distance

Optimized for flight altitudes of 300–500 m.

• Performs reliably even under 100 klx strong ambient light

• Measures well on surfaces with 10% reflectivity

• Adjustable pulse rate for mission-optimized performance

→ Result: greater coverage per flight, significantly improving mapping efficiency.

Small Laser Spot – High Energy

• Beam divergence of only 0.25 mrad → scan area 1/5 the size of the L2

• Captures tiny details such as power lines and thin branches

• Strong penetration through vegetation, retrieving more ground points beneath canopy

High Pulse Rate – Up to 2 Million Pulses per Second, Supporting 16 Returns

→ Enables extremely detailed 3D reconstruction, ideal for high-precision terrain mapping and complex structural surveys.

Three Flexible Scan Modes

Linear Mode

Uniform point distribution, optimized for high-precision topographic surveys.

Star-Shaped Mode

Balances accuracy and penetration—ideal for forests and dense urban areas.

Non-Repetitive Mode

Multiple scan angles, wide coverage—perfect for power line inspections and complex structures.

Dual 100MP RGB Cameras – Ultra-Wide, Ultra-Clear, Ultra-Efficient

• 4/3 CMOS sensors, mechanical shutter

• Supports pixel binning → effective 25MP high-quality images in low light

• 

• 107° ultra-wide FOV → very large area covered per capture

• With only 20% LiDAR sidelap, a single mission generates complete DOM & DEM

Maximum Efficiency

Combined with Matrice 400, each flight can cover up to 10 km², achieving 100 km² per day.

High Accuracy – Professional Survey-Grade

Next-Generation POS System

• Heading accuracy: 0.02°

• Pitch accuracy: 0.01° (post-processed, 1σ)

• LiDAR range repeatability: 5 mm at 150 m

LiDAR Data Accuracy

• Vertical error < 3 cm at 120 m

• < 5 cm at 300 m

• < 10 cm at 500 m

→ Meets 1:500 / 1:1000 / 1:2000 mapping standards.
Point clouds from L3 are over 2× thinner than L2, supporting advanced analysis.

Photogrammetry Accuracy

• GSD 3 cm at 300 m altitude

• No GCPs required thanks to real-time synchronized positioning

Penetration Capability – More Accurate Ground Data

Thanks to the small laser spot and high pulse energy, L3:

• Captures more ground points

• Maintains high completeness under vegetation

• Improves DEM accuracy and surface reconstruction

High Efficiency – Large-Scale Mapping Performance

Coverage up to 100 km² per day

With DJI Matrice 400:

• 10 km² per flight at 300 m altitude

• Stable operation supports 100 km² per day
  → Ideal for large-area surveys and high-speed mapping tasks.

Multiple Data Types in a Single Flight

Zenmuse L3 simultaneously collects LiDAR and RGB data, enabling production of:

• DEM (Digital Elevation Model)

• DOM (Digital Orthophoto Map)

• And various survey-grade datasets

A seamless workflow—from acquisition to processing to application—much simpler than multi-platform systems.

Intelligent Data Acquisition Experience

Point Cloud Preview

DJI Pilot 2 automatically recommends flight parameters based on the planned route.
Before takeoff, the system displays:

• Point density chart

• Point cloud distribution map

→ Helps evaluate expected data quality in advance.

Power Line Follow – Optimized for Power Line Inspection
