Description
DJI ZENMUSE L3
The DJI Zenmuse L3 is an ultra-high-precision aerial LiDAR system with an integrated dual RGB sensor, designed to revolutionize mapping, surveying, and technical inspection of large-scale infrastructure. This system combines a long-range laser module with two 4/3-inch CMOS sensors, offering a comprehensive solution for generating dense point clouds and three-dimensional models with millimeter-level accuracy from the air.
Thanks to its seamless integration with the DJI Matrice 400 platform, the Zenmuse L3 enables surveying of large areas at flight altitudes of up to 300 meters, significantly reducing field operation times and ensuring exceptional vegetation penetration by supporting up to 16 laser returns.
Main features
Ultra-long-range LiDAR: Detection up to 2,000 m (at 80% reflectivity) with a configurable pulse emission frequency of up to 2,000 kHz and support for up to 16 returns per pulse.
100 MP RGB mapping camera: Dual photogrammetric system with 4/3-inch CMOS sensors and a combined horizontal field of view of 107° for precise colorization of point clouds and orthophotos.
Proven centimeter-level accuracy: Vertical accuracy of 3 cm (RMSE) and horizontal accuracy of 4 cm (RMSE) when flying at an altitude of 120 meters, with a point cloud thickness of only 1.2 cm at 1σ.
High-performance POS system: High-update-rate IMU and GNSS module (200 Hz POS) that provides a post-processed yaw error of just 0.02°.
iRugged industrial design: IP54 protection rating for operation in demanding environments at temperatures ranging from −20 °C to 50 °C.
Ultra-fast storage: High-speed data transfer using CFexpress Type B memory cards.
Common applications
Topographic Surveys and Large-Scale Civil Engineering Inspections
Modeling and Monitoring of High-Voltage Lines, Catenaries, and Electrical Grids
Forest mapping and biomass estimation using tree canopy penetration
Water Resource Management, Risk Prevention, and Mining Inspection
Compatibility: Compatible with the DJI Matrice 400 multirotor platform (requires the specific Zenmuse L3 stabilizer connector). Fully integrated with the DJI Terra, DJI Modify, and DJI FlightHub 2 ecosystems.
