High-Precision Aerial LiDAR System DJI Zenmuse L2 + DJI Care 2 years
Powerful Range, Elevated Precision
The all-new DJI Zenmuse L2 integrates frame LiDAR with a high-accuracy IMU system and a 4/3 CMOS RGB mapping camera to provide DJI flight platforms with more precise and reliable geospatial data acquisition. When paired with DJI Terra the Zenmuse L2 delivers a turnkey solution for 3D data collection and high-accuracy post-processing. Supported by its powerful hardware - the L2 can allow for a precise scan of complex subjects within an extended range and faster point cloud acquisition.
Zaawansowane rozwiązanie LiDAR
Wspierany przez zaawansowaną technologię, ładunek użytkowy Zenmuse L2 pozwala na precyzyjne skanowanie złożonych obiektów w większym obszarze i pozwalając na jeszcze szybsze tworzenie chmur punktów.
High-Level Precision
By combining GNSS and a high-accuracy self-developed IMU, the Zenmuse L2 achieves 4cm vertical accuracy and 5cm horizontal accuracy.
Exceptional Efficiency
It’s ready for work as soon as the Zenmuse L2 is powered on and can collect both geospatial and RGB data from a 2.5km2 area in a single flight.
Intuitive Operation
When used with Matrice 350 RTK and DJI Terra, the Zenmuse L2 offers a turnkey solution that is simple to use, lowering the operational threshold.
30% Detection Range Increase
The Zenmuse L2 can detect from 250 meters at 10% reflectivity and 100 klx, and up to 450 meters at 50% reflectivity and 0 klx. The typical operational altitude now extends up to 120 meters, notably enhancing operational safety and efficiency.
Smaller Laser Spots, Denser Point Clouds
With a reduced spot size of 4×12 cm @100m, only a fifth of that of L1, L2 not only detects smaller objects with more details, but can also penetrate denser vegetation, generating more accurate digital elevation models (DEM).
Supports 5 Returns
In densely vegetated areas, L2 can capture more ground points beneath the foliage.
Effective Point Cloud Rate: 240,000 pts/s
In both single and multiple return modes, L2 can reach a max point cloud emission rate of 240,000 points per second, allowing the acquisition of more point cloud data in a given time frame.
Two Scanning Modes
L2 supports two scanning modes, offering flexibility for users based on their task demands. In repetitive scanning mode, L2's LiDAR can achieve more uniform and accurate point clouds while meeting high-precision mapping requirements. In non-repetitive scanning mode, it offers deeper penetration for more structural information, making it suitable for power line inspection, forestry surveying, and other scenarios.
High-Accuracy IMU System
The high-accuracy self-developed IMU system, combined with the drone’s RTK positioning system for data fusion during post-processing, gives L2 access to highly accurate absolute position, speed, and attitude information. In addition, the IMU system’s enhanced environmental adaptability improves the operational reliability and precision of L2.
Yaw Accuracy:
Real-time: 0.2°, post-processing: 0.05°
Pitch/Roll Accuracy:
Real-time 0.05°, post-processing 0.025°
No IMU Warm-up
The performance of the IMU system has been significantly enhanced, and it is ready for use the moment it's powered on. And, the accompanying drone is ready to begin tasks immediately once the RTK is in FIX status, delivering an optimized in-the-field experience.
RGB Mapping Camera
Pixel size has been enlarged to 3.3 µm, and effective pixels now reach 20 MP, resulting in a significant improvement in overall imaging, as well as more enriched true-color point cloud details. The minimum photo interval has been reduced to 0.7 seconds. The mapping camera has a shutter count of up to 200,000 times, further reducing operational costs. When point cloud collection is not needed, the RGB camera can still take photos and videos, or collect images for visible light mapping.

Detection Range
-
450m @50% reflectivity, 0 klx
250m @10% reflectivity, 100 klx
Typical data. Measured using a flat subject with a size larger than the laser beam diameter, perpendicular angle of incidence, and an atmospheric visibility of 23 km. In low-light environments, the laser beams can achieve the optimal detection range. If a laser beam hits more than one subject, the total laser transmitter power is split, and the achievable range is reduced. The maximum detection range is 500 m.

System Accuracy
-
Horizontal: 5 cm @ 150 m
Vertical: 4 cm @ 150 m
Measured under the following conditions in a DJI laboratory environment: Zenmuse L2 mounted on a Matrice 350 RTK and powered up. Using DJI Pilot 2’s Area Route to plan the flight route (with Calibrate IMU enabled). Using repetitive scanning with the RTK in the FIX status. The relative altitude was set to 150 m, flight speed to 15 m/s, gimbal pitch to -90°, and each straight segment of the flight route was less than 1500 m. The field contained objects with obvious angular features, and used exposed hard ground check points that conformed to the diffuse reflection model. DJI Terra was used for post-processing with Optimize Point Cloud Accuracy enabled. Under the same conditions with Optimize Point Cloud Accuracy not enabled, the vertical accuracy is 4 cm and the horizontal accuracy is 8 cm.
