DJI Zenmuse L3

Long Range, Wide Coverage
Zenmuse L3 achieves a maximum detection range of 950 m 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 reconstruction 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:

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

Small Spot, High 107° Ultra-Wide FOV
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.

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.

Up to 100 km² per Day
When mounted on DJI Matrice 400, Zenmuse L3 delivers outstanding efficiency. At a flight altitude of 300 m, a single flight can cover up to 10 km², enabling up to 100 km² of daily coverage

Multiple Deliverables in a Single Flight
Simultaneously captures LiDAR and RGB data to generate a range of mapping products from a single flight, including DEM, DOM, and more.

Data Acquisition
Point Cloud Result Preview
DJI Pilot 2 automatically recommends flight parameters based on user-defined routes and generates a Density Profile Chart and point cloud distribution charts before takeoff, enabling users to preview point cloud results.

Data Acquisition
Power Line Follow
Zenmuse L3 significantly enhances Power Line Follow, supporting operations up to 130m altitude. Without bypassing obstacles or crossing lines, Zenmuse L3 enables complete electrical corridor data acquisition in a single straight flight in most scenarios.

Data Acquisition
Flexible Split-Screen View
DJI Pilot 2 supports split-screen viewing of any two data sources—point cloud, RGB, or Vision Assist—allowing users to freely combine displays to suit their needs. During Power Line Follow or when the RGB cameras face downward, Vision Assist provides real-time forward-facing visuals, reducing flight risks and improving overall efficiency and safety.

Data Acquisition
Real-Time Point Cloud
Supports real-time point cloud SLAM reconstruction with instant 2D and 3D point cloud previews during operations, allowing users to monitor progress and take measurements as data is being collected. Point cloud results can also sync instantly to the cloud via DJI FlightHub 2 for rapid emergency response and assessment.

Data Acquisition
Cloud-Based Point Cloud Measurement
Zenmuse L3 point cloud outputs are fully compatible with DJI FlightHub 2. Users can view and manage point cloud data in real time, easily generate detailed flight routes, annotate and share points of interest, and perform advanced line and area measurements directly in the cloud.

Data Processing
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.

Data Processing
LiDAR Gaussian Splatting
DJI Terra enables advanced Gaussian Splatting fusion-based reconstruction of point cloud and RGB data collected by Zenmuse L3, dramatically enhancing the realism and detail of 3D models. This capability broadens the application scope of LiDAR across diverse mapping scenarios and delivers higher-quality 3D model outputs.

Data Processing
Fusion-Based Modeling
DJI Terra enables deep integration of LiDAR and RGB data. With a single acquisition, users can simultaneously generate high-accuracy point clouds, 2D maps, and 3D mesh models. This data fusion approach significantly enhances model completeness and detail, especially in environments with complex structures such as bridges and substations. It meets the needs of industries including energy, transportation, and infrastructure.
