1535nm Long-Range LiDAR

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.

Small Spot, High Energy

With a laser beam divergence of just 0.25 mrad, the spot size at the same range is significantly smaller. Higher energy density results in stronger penetration capability and improved accuracy in complex environments.

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 and dense point cloud data.

Scanning Modes

Supports Linear, Star-Shaped, and Non-Repetitive scanning modes for different operational scenarios. Provides flexible scanning angles, improved coverage, and optimized performance for complex environments.

High Accuracy

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) [5] 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 [6], 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 [7]. Real-time position synchronization enables operation without ground control points (GCPs), ensuring high-quality imagery for precise mapping.

High Penetration

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.

Data Acquisition

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 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.

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.

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.

Data Application

Smart Filter

DJI Modify supports intelligent semantic classification of point clouds, automatically distinguishing ground, vegetation, buildings, wires, electric towers, and more. After classification, users can efficiently adjust categories using Quick Selection and Structure Selection tools, further enhancing classification accuracy and processing efficiency.

Profile Tool

DJI Modify’s Profile tool allows users to flexibly select cross-sectional areas of point cloud models for intuitive analysis of terrain variation, structural features, and elevation profiles.

Comprehensive Output Capabilities

When paired with DJI Modify, Zenmuse L3 delivers versatile outputs. DJI Modify automatically generates a wide range of mapping products from point cloud data—including semantic point clouds, DEM, TIN, point grids, and contour lines—and supports multi-layer visualization. These outputs meet the diverse needs of engineering and design CAD-related workflows.
