The DJI Zenmuse L3 is a next-generation aerial LiDAR system designed for high-accuracy surveying, mapping, and geospatial data acquisition. Combining a powerful 1535nm long-range LiDAR sensor, dual 100MP RGB mapping cameras, a high-precision Position and Orientation System (POS), and a three-axis gimbal, the L3 delivers exceptional measurement accuracy and detailed point cloud data.
With a maximum detection range of up to 950 metres and the ability to cover up to 100 km² per day, the Zenmuse L3 significantly improves surveying efficiency. Designed for the DJI Matrice 400, it provides an integrated solution for large-scale mapping, infrastructure inspection, forestry, and terrain modelling.
