DJI’s next-generation precision LiDAR system offers long-range LiDAR with a range of up to 950 m [1], even on objects with only 10% reflectivity. Dual 100 MP RGB mapping cameras and a high-precision POS system accelerate geoinformation data collection, enabling daily coverage of up to 100 km² [2].
The Zenmuse L3 achieves a maximum detection range of up to 950 m [1] at a pulse frequency of 100 kHz, tested at an ambient light of 100 klx and on objects with 10% reflectivity. Adjustable pulse frequency allows for flexible performance and optimal adaptation to different operating conditions. Typical flight altitudes of 300-500 m [3] significantly extend the coverage of a single mission and increase mapping efficiency.
With a laser beam divergence of only 0.25 mrad (1/e²), the spot size at the same distance is approximately five times smaller than that of the Zenmuse L2, enabling the detection of smaller objects such as power lines or tree branches. The higher energy density of the beam ensures stronger penetration, significantly increasing the density of points on the ground under vegetation and enabling accurate reconstruction of complex terrain and structures.
With a maximum emission rate of up to 2 million laser pulses per second and support for up to 16 reflections [4], the Zenmuse L3 delivers highly accurate spatial reconstruction. Both point cloud density and penetration capability can be tailored to suit your needs – from high-precision mapping to complex terrain and vegetation environments.
The Zenmuse L3 supports three scanning modes – linear, star and non-repetitive – tailored to different mission types and environments:
Equipped with dual 100MP 4/3 CMOS RGB sensors and a mechanical shutter, the Zenmuse L3 system delivers significantly higher accuracy and shooting efficiency. Pixel binning technology enables an effective resolution of 25MP with a larger pixel size, ensuring excellent color rendition and sharpness even in low light conditions.
Dual RGB mapping cameras offer a horizontal field of view (FOV) of up to 107°, allowing for greater coverage with each shot. Even with a 20% lateral overlap of LiDAR data, it is possible to capture the data needed to create both digital orthophoto (DOM) and digital elevation models (DEM) in a single flight, significantly increasing the efficiency of the entire mapping process.
The Zenmuse L3 delivers significant improvements in both point cloud and RGB image accuracy, taking mapping efficiency to a new level. Combined with the DJI Matrice 400, it can cover up to 10 km² in a single flight, enabling high-precision mapping of up to 100 km² per day [2]. The result is large-scale, accurate data processed in a smooth and efficient workflow.
The enhanced high-precision POS system achieves a heading accuracy of 0.02° and a pitch accuracy of 0.01° (after processing, 1σ). The internal LiDAR technology solution provides a measurement repeatability of 5 mm at a distance of 150 m (1σ) [5] and supports synchronization in the microsecond range. Each unit undergoes rigorous factory calibration to ensure reliable and consistent measurement accuracy every time.
Vertical accuracy is better than 3 cm at 120 m, better than 5 cm at 300 m, and better than 10 cm at 500 m [6], which is fully sufficient for mapping projects at scales of 1:500, 1:1000, and 1:2000. The point cloud thickness generated by the Zenmuse L3 is only half that of the Zenmuse L2, enabling advanced analysis and high-precision applications.
With dual 100MP RGB mapping cameras, the Zenmuse L3 achieves 3cm GSD resolution even at 300m flight altitudes [7]. Real-time position synchronization enables missions without the need for ground control points (GCPs), ensuring high-quality imagery for accurate and reliable mapping.
With a smaller laser spot and higher energy per pulse, the 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 and enabling detailed surface modeling and reconstruction.
When used on the DJI Matrice 400, the Zenmuse L3 achieves exceptional mapping efficiency. At a flight altitude of 300 m, a single flight can cover up to 10 km², enabling daily coverage of up to 100 km².
This combination represents the optimal solution for large-scale mapping projects where accuracy, speed, and reliable performance in the field are important.
The DJI Zenmuse L3 can simultaneously record both LiDAR and RGB data, creating a wide range of mapping outputs from a single flight, including digital elevation models (DEMs), digital orthophotos (DOMs), and more.
This integrated approach significantly speeds up the workflow, increases accuracy, and simplifies data processing within a single mission.
The DJI Zenmuse L3 seamlessly integrates into the DJI ecosystem, delivering a comprehensive end-to-end mapping solution. From data collection, processing, and practical use of results, the entire workflow is unified, intuitive, and efficient.
Compared to traditional multi-platform systems, this integrated workflow is significantly easier to operate, faster to master, and allows users to efficiently perform a wide range of mapping tasks with maximum accuracy and reliability.
The DJI Pilot 2 app automatically recommends flight parameters based on the user's chosen route and generates a Density Profile Chart and Point Cloud Distribution Chart before takeoff, allowing you to preview the scan results before the mission.
The Zenmuse L3 significantly expands the Power Line Follow feature, supporting flights at altitudes of up to 130 m. Without the need to avoid obstacles or cross power lines, the system can capture complete power corridor data in a single direct flight, increasing inspection efficiency and accuracy.
DJI Pilot 2 allows you to view any two data sources – such as point clouds, RGB footage or Vision Assist – in a split view. This allows the user to combine views as needed. During Power Line Follow mode or when the cameras are pointing downwards , Vision Assist provides a real-time forward view, reducing flight risk and increasing safety and efficiency.
The system supports real-time SLAM reconstruction, which enables instant 2D and 3D point cloud views during a mission. This allows the operator to monitor the scan progress, measure distances, and check coverage while data is being collected. The point cloud results can be instantly synced to the cloud via DJI FlightHub 2, enabling rapid response and immediate evaluation in emergency or time-sensitive situations.
Point cloud outputs from the Zenmuse L3 system are fully compatible with DJI FlightHub 2. Users can track and manage data in real time, create detailed flight paths, mark and share points of interest, and perform precise length and area measurements directly in the cloud.
DJI Terra software features powerful integrated PPK capabilities that are compatible with both the DJI D-RTK 3 system and standard reference base station data. The platform supports local PPK processing for both RGB imagery and LiDAR data, ensuring centimeter-level positioning accuracy even in areas with poor network connectivity or where RTK signals are not available.
This advanced system increases the reliability of results, minimizes error rates, and enables users to achieve accurate mapping outputs even in challenging conditions.
DJI Terra software features advanced reconstruction technology based on Gaussian Splatting, a fusion of data from LiDAR and RGB cameras on the DJI Zenmuse L3. This process significantly increases the realism, detail, and visual quality of 3D models, accurately depicting the surface, structure, and texture of objects.
This innovative method is expanding the use of LiDAR data across a variety of mapping and engineering applications – from architecture and urban planning, to infrastructure inspections, to precise 3D terrain modeling. The result is higher quality and more realistic 3D outputs that bring a new level of accuracy and visual fidelity.
DJI Terra software enables deep integration of LiDAR and RGB data, allowing users to create high-precision point clouds, 2D maps, and 3D network models from a single data collection. This data fusion approach significantly improves the completeness and detail of models, especially in environments with complex structures such as bridges, substations, and industrial facilities.
Thanks to this technology, DJI Terra meets the needs of industries such as energy, transportation, and infrastructure, where accuracy, reliability, and realistic object reconstruction are key.
DJI Modify software supports intelligent semantic point cloud classification, which automatically recognizes and separates the ground surface, vegetation, buildings, wires, power poles, and other objects. This process significantly speeds up data processing and improves classification accuracy without the need for manual intervention.
After automatic sorting, users can easily edit categories using the Quick Selection and Structure Selection tools, allowing for efficient detail control and optimization of results for precision mapping and engineering applications.
The Profile Tool feature in DJI Modify software allows users to flexibly select cross-sections of point clouds and intuitively analyze terrain variations, structural features, and elevation profiles.

When combined with DJI Modify software, the DJI Zenmuse L3 offers extremely broad and flexible output options. DJI Modify automatically generates various mapping products from point clouds, such as semantically classified point clouds, digital elevation models (DEMs), TINs, point grids, and contour lines.
The software also supports multi-layer visualization, allowing users to efficiently analyze and combine different data layers as needed for a project. These outputs are fully compatible with CAD and engineering workflows, meeting the diverse requirements of surveying, design, and infrastructure modeling.
The DJI Zenmuse L3 supports CFexpress™ card encryption, ensuring secure data storage and protecting it from unauthorized access or theft. When combined with the DJI Matrice 400 drone, the system also offers easy one-click deletion of recording logs and AES-256 video transmission encryption, which is among the most secure standards in the industry.
Together, these features guarantee maximum data protection and confidentiality, which is especially crucial for professional mapping, industrial and government projects where information security is paramount.
The DJI Zenmuse L3 is fully compatible with the DJI Matrice 400 drone and requires the use of the Zenmuse L3 Single Gimbal Connector. When mounting, ensure that the gimbal connector is connected to the E1 port on the bottom of the drone.
If the device is connected to the wrong port, the accuracy of mapping and calibration during flight may be reduced.
The DJI Zenmuse L3 achieves an IP54 rating under IEC 60529, tested under controlled laboratory conditions. This rating protects the device from dust and splashing water.
To maintain the highest level of protection, the following instructions must be followed:
The DJI Zenmuse L3 supports different laser pulse emission frequencies depending on the desired data density and environmental penetration. The number of “returns” depends on the selected pulse frequency as follows:
A lower pulse frequency allows for more returns and better penetration of vegetation, while a higher frequency provides a denser point cloud at a lower range – ideal for mapping from lower altitudes.
The DJI Zenmuse L3 supports three scanning modes, which are optimized for different operational scenarios:
Each mode allows you to customize the balance between accuracy, speed, and penetration according to the type of project and environment.
The dual 100 MP RGB mapping camera system expands the horizontal field of view (FOV) to 107°, allowing you to cover a larger area with each shot.
Even with a 20% lateral overlap of LiDAR data, the system can capture the data needed to create both a digital orthophoto map (DOM) and a digital elevation model (DEM) in a single flight.
This significantly increases mapping efficiency, as it allows for the combined collection of LiDAR and RGB data without the need for multiple flights over the same area.
To ensure consistent exposure in final images, each camera uses center-weighted metering to optimize resolution and detail.
If the left and right cameras capture scenes with significantly different lighting conditions (e.g., shade and direct sunlight), there may be visible differences in brightness between the two images in Liveview.
However, these differences do not affect the resulting quality of the photos, because the exposure of both cameras is automatically equalized during processing.
