DJI Zenmuse L3 – a long-range laser scanning system capable of reaching a distance of 950 m even on objects with a reflectivity of only 10%. Two 100-megapixel RGB cameras and a high-precision POS system accelerate geospatial data acquisition, providing daily coverage of up to 100 km².
Zenmuse L3 combines long-range 1535nm LiDAR, dual 100MP RGB cameras for mapping, a high-precision POS system, and a three-axis gimbal—all in a compact device that delivers unmatched performance for its size.
Big action, wide coverage
The Zenmuse L3 achieves a maximum detection range of 950 m at a 100 kHz pulse rate, tested under 100 klx illumination and on 10% reflectivity targets. The adjustable pulse rate allows flexible output power adjustment and optimal adaptation to various operating conditions. Typical flight altitudes of 300 to 500 m significantly expand the coverage area in a single flight and improve mapping efficiency.
Thin beam, high power
With a laser beam divergence of just 0.25 mrad (1/e²), the beam size at the same range is approximately one-fifth that of the Zenmuse L2, enabling detection of smaller objects such as power lines and tree branches. The higher energy density provides improved penetration, significantly increasing the density of points on the surface beneath vegetation and enabling highly accurate reconstruction of complex terrain and structures.
High frequency, multiple reflections
With a maximum laser pulse rate of 2 million pulses per second and support for up to 16 returns, the Zenmuse L3 delivers highly accurate spatial reconstruction. Point cloud density and penetration depth can be adjusted to suit needs, from high-precision mapping to complex environments.
Scanning modes
Supports linear, star and non-repetitive scanning modes for various working scenarios:
Linear: Provides a more uniform distribution of the point cloud, ideal for high-precision terrain mapping.
Star: Provides a balance between accuracy, multiple scanning angles and penetration capability, well suited for wooded areas or dense urban environments.
Non-repetitive: Provides multiple scanning angles and wider coverage, optimized for power line inspections and other complex structural surveys.
Dual 100MP RGB camera for mapping
The Zenmuse L3 features a dual 100-megapixel 4/3 RGB CMOS camera and a mechanical shutter, providing significantly improved accuracy and efficiency. Pixel binning technology maintains an effective resolution of 25 MP with a larger pixel size, delivering superior color reproduction even in low light.
107° ultra-wide viewing angle
Two RGB cameras provide a horizontal field of view (FOV) of up to 107°, allowing for a wider area to be captured with each image. Even with the 20%'s low lateral LiDAR coverage, you can acquire data for both digital orthophotos (DOMs) and digital elevation models (DEMs) in a single flight, significantly increasing operational efficiency.
Precision meets efficiency
The Zenmuse L3 delivers significant improvements in both point cloud and RGB color accuracy, while simultaneously taking efficiency to a new level. When paired with the DJI Matrice 400, a single flight can cover up to 10 km², delivering up to 100 km² of high-precision mapping per day. Large-area surveys and high accuracy are achieved through a seamless workflow.
Patented high-precision system
The upgraded, high-precision POS system provides a heading accuracy of 0.02° and a pitch accuracy of 0.01° (after post-processing, 1σ). Our lidar system provides a measurement repeatability of 5 mm at a distance of 150 m (1σ) and maintains time synchronization with microsecond accuracy. Each unit undergoes rigorous factory calibration to ensure consistently reliable survey results.
LiDAR data accuracy
Vertical accuracy is greater than 3 cm at 120 m, greater than 5 cm at 300 m, and greater than 10 cm at 500 m, enabling easy mapping projects at scales of 1:500, 1:1000, and 1:2000. The point cloud thickness of the Zenmuse L3 is only half that of the Zenmuse L2, enabling advanced analysis and high-precision applications.
Photogrammetric accuracy
With dual 100-megapixel RGB mapping cameras, the Zenmuse L3 achieves a ground sampling distance (GSD) of 3 cm even at a flight altitude of 300 m. Real-time position synchronization allows operation without ground control points (GCPs), ensuring high-quality images for accurate mapping.
High dot density
With a smaller laser beam and higher single-pulse energy, the Zenmuse L3 delivers superior penetration. In topographic surveying and similar applications, it captures more points on the surface with greater completeness, significantly improving the accuracy and integrity of terrain data for precise surface fitting and reconstruction.
High efficiency
Up to 100 km² per day
When mounted on the DJI Matrice 400, the Zenmuse L3 delivers exceptional performance. At an altitude of 300 m, it can cover up to 10 km² in a single flight, providing up to 100 km² of daily coverage.
Several results in one flight
Simultaneously collects LiDAR and RGB data to create a range of mapping products in a single flight, including DEM, DOM, and more.
Comprehensive solution
The Zenmuse L3 seamlessly integrates with the DJI ecosystem, providing a comprehensive mapping solution. This unified workflow, from data collection and processing to application, is easier to use and learn than traditional multi-platform setups, helping users effectively complete a wide range of mapping tasks.
Data security
The Zenmuse L3 supports CFexpress™ memory card encryption, providing reliable protection for stored data and preventing unauthorized access or data theft. The Matrice 400 offers one-click log clearing and AES-256 encryption for video transfer, further guaranteeing data privacy.
