ZENMUSE L Series

Powerful Range, Elevated Precision

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.

Frame-Based LiDAR

Zenmuse features:

30% Detection Range Increase

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.

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.

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).

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.

RGB Mapping Camera

The Zenmuse L2s, equipped with a 4/3 CMOS sensor, showcases a notable advancement in imaging technology. The pixel size has been enlarged to an impressive 3.3 μm, resulting in a substantial boost in effective pixels, now reaching 20 MP. This enhancement translates to a marked improvement in overall imaging quality, ensuring more detailed and vivid true-color point cloud data.

One of the standout features of the Zenmuse L2s is its reduced minimum photo interval, now set at a swift 0.7 seconds. This enhancement enhances the efficiency of data acquisition, enabling the camera to capture a comprehensive dataset with minimal downtime.

Furthermore, the mapping camera is engineered with durability in mind, featuring a mechanical shutter with a shutter count of up to 200,000 cycles. This robust design not only contributes to the camera’s longevity but also serves to minimize operational costs, making it a cost-effective solution for prolonged and demanding use.

Even when not actively engaged in point cloud collection, the RGB camera of the Zenmuse L2s remains versatile. It can seamlessly transition to capturing high-quality photos and videos or collecting images specifically tailored for visible light mapping applications. This adaptability ensures that the Zenmuse L2s is a reliable and multifaceted tool, catering to a diverse range of aerial imaging and mapping needs.

Integrated LiDAR Solution

Supported by its powerful hardware, L2 can allow for a precise scan of complex subjects within an extended range and faster point cloud acquisition. During operations, users can preview, playback, and process point cloud models on-site, with Task Quality Reports generated by DJI Terra, offering a simple, one-stop solution to improve overall efficiency. This enables users to achieve high-precision point cloud results with one-stop post-processing.
