DJI Zenmuse L3 LIDAR SENSOR for Matrice 400 Long-Range, High-Accuracy Aerial LiDAR System

The DJI Zenmuse L3 is a next-generation aerial LiDAR payload designed for professional surveying, mapping, inspection, and 3D data acquisition. As DJI’s first high-accuracy long-range airborne LiDAR system, it integrates a 1535 nm LiDAR module, dual 100 MP RGB mapping cameras, a high-precision POS system, and a 3-axis gimbal into one compact solution. Built for large-scale and complex environments, Zenmuse L3 delivers high-density point clouds, detailed visual data, and reliable accuracy for demanding geospatial and infrastructure workflows. Highlights 1. Long-range LiDAR performance Zenmuse L3 offers strong long-distance detection capability, making it well suited for wide-area missions and difficult terrain. According to the provided specifications, it can detect targets at up to 950 m at 10% reflectivity (100 kHz) and up to 2000 m at 80% reflectivity. 2. Survey-grade accuracy The system is built for precision. At a flight altitude of 120 m, it delivers 3 cm vertical accuracy and 4 cm horizontal accuracy (RMSE). Even at 300 m, it maintains 5 cm vertical accuracy and 7.5 cm horizontal accuracy, supporting efficient operations without giving up data quality. 3. High-quality point clouds with dual RGB mapping cameras Zenmuse L3 combines LiDAR data with dual 100 MP RGB mapping cameras, enabling users to capture both accurate geometry and rich visual information in a single workflow. Its combined horizontal field of view reaches 107°, supporting efficient mapping and 3D reconstruction. 4. Efficient large-area coverage Designed for productivity, Zenmuse L3 is ideal for projects that require fast collection over large areas. Its integrated DJI workflow supports efficient data capture, processing, and application across surveying and inspection tasks. 5. Strong performance in complex environments With multi-return capability and robust ranging performance, Zenmuse L3 is suitable for environments with vegetation cover, uneven terrain, corridor infrastructure, and hard-to-capture surfaces. 6. Industrial-grade reliability Zenmuse L3 is built for professional field work, featuring IP54 protection, an operating temperature range of -20°C to 50°C, and support for the DJI Matrice 400 platform. Best For Zenmuse L3 is best suited for: Large-scale topographic surveying and terrain mapping Powerline, corridor, road, river, and infrastructure inspection Forestry, mountainous, and vegetation-covered environments High-precision 3D modeling and digital twin data capture Professional teams using the DJI ecosystem for end-to-end workflow integration Specifications System Specifications Product Name Zenmuse L3 Point Cloud System Accuracy At 120m Flight Altitude: Vertical Accuracy: 3 cm (RMSE) Horizontal Accuracy: 4 cm (RMSE) At 300m Flight Altitude: Vertical Accuracy 5 cm (RMSE) Horizontal Accuracy: 7.5 cm (RMSE) Measured under the following conditions in a DJI laboratory environment: 1. The field contained objects with obvious angular features. DJI Matrice 400 was linked to a position-calibrated D-RTK 3 Multifunctional Station. The flight route was planned using DJI Pilot 2's Area Route (with Calibrate IMU enabled) with Linear scanning. The flight speed was set to 15 m/s, gimbal pitch to -90°, and each straight segment of the flight route was less than 3300 m. 2. Using exposed hard ground checkpoints that conformed to the diffuse reflection model. 3. DJI Terra was used for post-processing with Optimize Point Cloud Accuracy enabled. Point Cloud Thickness 1.2 cm@1σ (120m nadir flight altitude) 2 cm@1σ (300m nadir flight altitude) Measured in Linear scanning mode, using check points on 80% reflectivity objects, with neither point cloud optimization nor downsampling enabled in DJI Terra. For 6σ, multiply the listed thickness by 6. Combined Horizontal FOV (Dual RGB Mapping Cameras) 107° Composed by merging images from two cameras with a 45° optical axis angle between them. RGB Ground Sampling Distance (GSD) Average Value: 3 cm (300m nadir flight altitude) For detailed calculation methods, refer to the user manual available on the Downloads page of the official DJI Zenmuse L3 webpage.
