DJI Zenmuse L3

Hardware Performance Redefined

Long Range, Wide Coverage ​

enmuse L3 achieves a maximum detection range of 950m at a pulse rate of 100kHz, 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 500m significantly expand single-flight coverage and boost mapping efficiency.

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

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

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.

High Accuracy

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 150m (1σ) [5] and supports microsecond-level time synchronization. Each unit undergoes rigorous factory calibration to ensure consistently reliable survey results.

Vertical accuracy is better than 3cm at 120m altitude, better than 5cm at 300m, and better than 10cm at 500m, 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.

With dual 100MP RGB mapping cameras, Zenmuse L3 achieves a ground sample distance (GSD) of 3cm 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 ​

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.
