DJI Zenmuse L3

DJI Zenmuse L3 

DJI is proud to introduce the new high-integration aerial LiDAR and camera system Zenmuse L3, designed for professional mapping, infrastructure inspection, forestry, and industrial applications.

The L3 combines an advanced LiDAR module with an improved detection range, a high-performance RGB camera (possibly 4/3-inch or full-frame sensor), a built-in high-precision IMU, and a 3-axis stabilized gimbal.

• Supports up to 5 (or more) laser returns and generates an even denser point cloud for penetration through vegetation and complex surfaces.
• Significantly extended detection range (e.g., 300–500 m for low-reflectivity targets) and improved vertical and horizontal accuracy (approximately 2–3 cm vertical, 3–4 cm horizontal), suitable for 1:1000-scale topographic mapping or better.
• Enhanced compatibility with Matrice RTK platforms and optimized workflow with DJI Terra software for seamless LiDAR data processing and photogrammetry.
• Increased reliability: improved IMU calibration, wider operating temperature range, and reduced module weight for easier integration and deployment.
• Ideal for large-scale mapping and survey missions — capable of covering extensive areas in one or two flights.

Application Scenarios

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 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.
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.

PPK Data Processing

DJI Terra features robust built-in PPK (Post-Processed Kinematic) capabilities, compatible with D-RTK 3 and standard base station data. The platform supports local PPK for RGB imagery and LiDAR, providing centimeter-level positioning accuracy even in areas with limited network connectivity or where RTK is unavailable.
