Hardware Performance Redefined
Zenmuse L3 integrates a 1535nm long-range LiDAR, dual 100MP RGB mapping cameras, a high-precision POS system, and a three-axis gimbal, all within a compact device, delivering unprecedented performance for its size.
Long Range, Wide Coverage
Zenmuse L3 achieves a maximum detection range of 950m at a pulse rate of 100 kHz, 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 500 m significantly expand single-flight coverage and boost mapping efficiency.
Small Spot, High Energy
With a laser beam divergence of just 0.25 mrad (1/e2), the spot size at the same range is about one-fifth that of Zenmuse L2, enabling detection of smaller objects such as power lines and branches. Higher energy density results in stronger penetration capability, significantly increasing ground point density beneath vegetation and enabling high-accuracy construction of complex terrains and structures.
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:
Non-Repetitive: Provide multiple scan angles and broader coverage, optimized for power line inspections and other complex structural surveys.
Dual 100 MP RGB Mapping Cameras
Equipped with dual 100MP 4/3 CMOS RGB sensors and a mechanical shutter, Zenmuse L3 delivers significantly enhanced accuracy and efficiency. Pixel binning support an effective 25MP resolution with larger pixel size, producing superior color reproduction even under poor lighting conditions.
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 5cm 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.
End-To-End Solution
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.
