Zenmuse L2 integrates frame LiDAR, a self-developed high-accuracy IMU system, and a 4/3 CMOS RGB mapping camera, providing DJI flight platforms with more precise, efficient, and reliable geospatial data acquisition. When used with DJI Terra, it delivers a turnkey solution for 3D data collection and high-accuracy post-processing.
High Precision
Vertical: 4 cm
Horizontal: 5 cm
Exceptional Efficiency
2.5 km2 covered in a single flight
Detection Range
250m @10% reflectivity, 100klx
450m @50% reflectivity, 0klx
Frame-Based LiDAR
30% Detection Range Increase
L2 can detect from 250 meters at 10% reflectivity and 100 klx, [3] and up to 450 meters at 50% reflectivity and 0 klx. [3] 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.
Frame-based Design
The frame-based design results in an effective point cloud data rate of up to 100%. Together with a three-axis gimbal, it brings more possibilities to surveying scenarios.
High-Accuracy IMU System
Improved Accuracy
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
4/3 CMOS, Mechanical Shutter
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.
