We are thrilled to announce the launch of the DJI Zenmuse L3, a revolutionary aerial LiDAR system that is set to redefine efficiency and precision in professional geospatial operations. Combining a powerful long-range LiDAR module, dual high-resolution RGB cameras, and a proprietary high-precision positioning system, the Zenmuse L3 delivers a comprehensive, end-to-end solution for high-accuracy mapping across vast and complex environments.
Product Overview: Precision Meets Efficiency
The Zenmuse L3 represents a major technological leap, integrating a next-generation 1535 nm LiDAR and dual 100MP RGB cameras into a single, compact payload. Designed for the DJI Matrice 400 and compatible with other platforms like the Matrice 350 RTK, the L3 dramatically extends operational range and detail capture.
-
Unprecedented Range: Achieve a maximum detection range of 950 meters (at 10% reflectivity), more than double its predecessor, allowing for safer, higher-altitude flights that still capture exceptional detail.
-
Dual 100MP Cameras: The dual 4/3 CMOS RGB sensors with a mechanical shutter capture ultra-high-resolution imagery (up to 12K), enabling the generation of stunning, true-color point clouds and high-quality photogrammetric products like Digital Orthophoto Maps (DOM).
-
Superior Penetration: With an industry-leading 16 returns per laser pulse and a maximum pulse emission frequency of 2 million points per second, the L3 provides unparalleled ground point density beneath dense vegetation, crucial for accurate terrain mapping in forested areas.
-
Fluxo de trabalho integrado: The L3 seamlessly integrates with DJI’s ecosystem, including D-RTK 3, DJI Pilot 2, and the post-processing software DJI Terra e Modificar DJI, simplifying the entire workflow from mission planning to final data delivery.
