DJI Zenmuse L3

DJI Zenmuse L3

Overview
DJI"s next-generation high-accuracy aerial LiDAR system features a long-range LiDAR capable of reaching up to 950 m [1] even on objects with just 10% reflectivity. Dual 100MP RGB mapping cameras and a high-precision POS system accelerate geospatial data acquisition, enabling daily coverage of up to 100 km²
Zenmuse L3 integrates a 1535nm long-range LiDAR, dual 100MP RGB mapping cameras, a high-precision POS system, and a three-axis gimbal, all within a compact device, delivering unprecedented performance for its size.
