The Zenmuse L2 payload combines LiDAR technology, a proprietary high-accuracy IMU system and a 4/3 CMOS RGB mapping camera for even more precise, efficient and reliable geospatial data acquisition
Backed by advanced technology, the Zenmuse L2 payload allows precise scanning of complex objects over a larger area and enabling even faster point cloud creation.
Thanks to the combination of GNSS and a proprietary IMU module, measurements reach an accuracy of 4 cm vertically and 5 cm horizontally.
Ready to work immediately after switching on. Collect geo-spatial and RGB data from a 2.5 km2 area in a single flight.
Combined with the DJI Matrice 350 RTK drone and DJI Terra software, the Zenmuse L2 LiDAR scanner offers a ready-to-use and easy-to-use solution.
The Zenmuse L2 can detect measurements from a distance of 250 meters at 10% reflectivity and 100 klx brightness, and up to 450 meters at 50% reflectivity and 0 klx brightness.
With a reduced spot size of 4×12 cm @100 meters, just one-fifth of that of the Zenmuse L1, the Zenmuse L2 not only detects smaller objects with more detail, but can also penetrate denser vegetation, generating more accurate digital elevation models (DEMs)...,
In areas of dense vegetation, the Zenmuse L2 can capture more ground points beneath the foliage.
In both linear (repetitive) and non-repetitive (non-repetitive) scanning modes, Zenmuse L2 can achieve a maximum point cloud processing speed of 240,000 points per second.
In line scan mode (repetitive scanning), more uniform and accurate point clouds can be achieved while meeting the requirements for precise mapping. The non-repetitive scanning mode (non-repetitive scanning) offers deeper penetration for more structural information, making it suitable for power line inspections, forest surveys and other scenarios.
An advanced high accuracy IMU system, combined with a drone equipped with an RTK positioning system, provide Zenmuse L2 with access to highly accurate absolute position, velocity and location information.
The performance of the IMU system has been greatly enhanced and it is ready for use as soon as the power is turned on. The drone is ready to start tasks as soon as the RTK is set to FIX status, ensuring optimized performance in the field.
The pixel size has been increased to 3.3 μm, and the effective pixel count now reaches 20 MP, resulting in a significant improvement in overall imaging, as well as greater point cloud detail in true colors. When point cloud creation is not required, the RGB camera can still take photos and videos or collect images for visible-light mapping.
