DJI Zenmuse L3: Long-Range LiDAR and Dual 100 MP Camera Payload for Survey-Grade Mapping The DJI Zenmuse L3 is a long-range LiDAR and dual 100 MP mapping payload designed for surve y-grade aerial mapping, topographic surveys, infrastructure inspection, and digital twin creation. Built for the DJI Matrice 400 RTK, it delivers up to 950 m LiDAR range, 2–4 cm accuracy, and high-density point cloud capture, helping surveyors and engineers map larger areas faster with fewer flights. Equipped with a 1535 nm Class 1 laser and dual 100 MP Micro 4/3 cameras, it delivers up to 950 m range and 2–4 cm accuracy for professional surveying and digital-twin applications. Additionally, the L3 integrates seamlessly into DJI Terra workflows to output point clouds, orthophotos, and 3D models—all within a single processing environment. Quick Look Long-range LiDAR system: 950 m @ 10% (100 kHz) and 700 m @ 10% (350 kHz). High-efficiency mapping: covers up to 10 km² per flight or 100 km² per day Survey-grade accuracy: delivers 2–4 cm precision for mapping applications. Adjustable point-rate control: 100 kHz – 2 MHz to balance density and coverage. Configurable returns: 16 (100 / 350 kHz), 8 (1000 kHz), 4 (2000 kHz). Dual 100 MP Micro 4/3 cameras: generate orthophotos and colorized point clouds. Real-time point-cloud preview: measure points, lines, and areas in DJI Pilot 2. Compact low-power design: 1.6 kg payload draws only 64 W typical power. Rugged environmental build: IP54 rated for –20 °C to +50 °C operation. Streamlined workflow: integrates directly with DJI Terra and Modify. DJI Care Enterprise Plus: 1-Year coverage activated upon first use. Exceptional Range, Accuracy, and Efficiency The Zenmuse L3 combines long-distance LiDAR reach with exceptional spatial precision. Its reduced 41 mm beam diameter and 0.25 mrad divergence produce higher-resolution point clouds and finer target separation. Adjustable scanning rates from 100 kHz to 2 MHz, plus up to 16 returns, provide flexibility for both dense urban modeling and deep vegetation mapping. With a no-preheat IMU, 0.01° pitch/roll and 0.02° heading accuracy, and auto-calibration during flight, the L3 ensures every mission begins instantly and captures consistent, high-integrity data. Integrated Dual Cameras and All-Weather Reliability Dual 100 MP Micro 4/3 sensors with 107° FOV capture ultra-sharp color imagery for photogrammetry and point-cloud colorization. The system delivers 1.2 cm GSD at 120 m AGL or 3 cm GSD at 300 m, ensuring photorealistic results for engineering-grade mapping. The IP54-rated housing withstands rain, dust, and temperature extremes from -25 °C to +55 °C. P owered by DJI’s unified ecosystem, the L3’s workflow with DJI Terra and Modify offers real-time point-cloud preview, on-site measurement, and automated accuracy checks—all backed by 1-Year DJI Care Enterprise Plus coverage.
