DJI Zenmuse L3
DJI's next-generation high-accuracy aerial LiDAR system features a long-range LiDAR capable of reaching up to 950 m [1] even on objects with just 10% reflectivity. Dual 100MP RGB mapping cameras and a high-precision POS system accelerate geospatial data acquisition, enabling daily coverage of up to 100 km² [2]. Equipped with a 1535 nm Class 1 laser and dual 100 MP Micro 4/3 cameras, it delivers up to 950 m range and 2–4 cm accuracy for professional surveying and digital-twin applications. Built exclusively for the Matrice 400 RTK, the L3 integrates seamlessly into DJI Terra workflows to output point clouds, orthophotos, and 3D models—all within a single processing environment.

1535nm Long-Range LiDAR
Zenmuse L3 achieves a maximum detection range of 950 m [1] 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 [3] 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 [4], 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 Camera System
Dual 100 MP Micro 4/3 sensors with 107° FOV capture ultra-sharp color imagery for photogrammetry and point-cloud colorization. The system delivers 1.2 cm GSD at 120 m AGL or 3 cm GSD at 300 m, ensuring photorealistic results for engineering-grade mapping.
The IP54-rated housing withstands rain, dust, and temperature extremes from -25 °C to +55 °C. Powered by DJI’s unified ecosystem, the L3’s workflow with DJI Terra and Modify offers real-time point-cloud preview, on-site measurement, and automated accuracy checks—all backed by 1-Year DJI Care Enterprise Plus coverage.
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.
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.
High Efficiency
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.
Additional Notes
1.
a. Range Definition: The range is defined as the distance at which 50% of the emitted laser pulses are detected. If a laser beam hits more than one subject, the total laser transmitter power is split and the achievable range is reduced.
b. Test Conditions: 100 klx ambient light, within the central area of the FOV, using a flat subject with a size larger than the laser beam diameter, a perpendicular angle of incidence, and an atmospheric visibility of 23 km.
c. The maximum detection range is 900 m by default. For a longer range, contact DJI support or an authorized dealer.
2. When paired with DJI Matrice 400, Zenmuse L3 can achieve a daily mapping coverage of up to 100 km² (flat terrain, 300m nadir flight altitude, 20% side overlap, 17m/s flight speed, and a total effective flight time of 6 hours).
3. The flying altitude limit varies in different countries or regions. Make sure to fly at the altitudes outlined by local laws and regulations.
4. Support for 16 returns is limited to laser pulse emission frequency of 100 kHz and 350 kHz.
5. Tested at 150 m under ambient temperature of 25° C (77° F) and 80% object reflectivity. Actual results may vary depending on environmental and operational conditions. Data is provided for reference only.
6. Measured under the following conditions in a DJI laboratory environment:
a. The field contained objects with obvious angular features. DJI Matrice 400 was linked to a position-calibrated D-RTK 3 Multifunctional Station. The flight route was planned using DJI Pilot 2's Area Route (with Calibrate IMU enabled) with Linear scanning. The flight speed was set to 15 m/s, gimbal pitch to -90°, and each straight segment of the flight route was less than 3300 m.
b. Using exposed hard ground checkpoints that conformed to the diffuse reflection model.
c. DJI Terra was used for post-processing with Optimize Point Cloud Accuracy enabled.
7. For detailed calculation methods, refer to the user manual available on the Downloads page of the official DJI Zenmuse L3 webpage.
8. The service plans offered in different countries or regions may differ. For more information, please consult your local authorized dealer.
