LIDAR system with DJI Zenmuse L2 mapping camera
Powered by powerful hardware, L2 can enable precise scanning of complex objects over a greater range and faster point cloud acquisition. During operations, users can view, playback and process point cloud models on-site using job quality reports generated by DJI Terra, providing a simple, all-in-one solution to improve overall efficiency. This enables users to obtain precise point cloud results with one post-processing.
Increased detection range by 30%
The L2 can detect from a distance of 250 meters at 10% reflectance and 100 klx and up to 450 meters at 50% reflectivity and 0 klx. Typical operating altitude now reaches 120 meters, significantly increasing operational safety and efficiency.
Smaller laser spots, denser point clouds
With a reduced spot size of 4x12 cm at 100 m, which is only one fifth of the spot size of the L1, the L2 not only detects smaller objects with greater detail, but can also penetrate denser vegetation, generating more accurate digital elevation models (DEMs) .
Supports 5 phrases
In densely vegetated areas, L2 can capture more ground points under the foliage.
Effective point cloud speed: 240,000 points/sec
In both single and multiple return modes, L2 can achieve a maximum point cloud emission rate of 240,000 points per second, enabling more point cloud data to be acquired in a given time frame .
Two scanning modes
L2 supports two scanning modes, offering users flexibility depending on their requirements. In repetitive scanning mode, LiDAR L2 can obtain more uniform and accurate point clouds while meeting precision mapping requirements. In single scan mode, it provides deeper penetration to obtain more structural information, making it suitable for power line inspections, forest surveys and other scenarios.
Frame based design
The frame-based design provides an effective point cloud data rate of up to 100%. Combined with a three-axis gimbal, it provides more possibilities for surveying scenarios.
4/3 CMOS, mechanical shutter
The pixel size has been increased to 3.3 μm and the effective pixels now reach 20 MP, resulting in significant improvements in overall imaging as well as richer point cloud details in true colors. The minimum photo interval has been reduced to 0.7 seconds. The mapping camera can have a shutter speed 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.
