Overview
The DJI Zenmuse L3 is a next-generation, long-range aerial LiDAR solution engineered for high-accuracy surveying, mapping, inspection, and geospatial data acquisition. Designed for integration with the DJI Matrice 400, the L3 combines a 1535 nm long-range LiDAR system, a high-precision Position and Orientation System (POS), and dual 100 MP 4/3 CMOS RGB mapping cameras. This advanced sensor suite delivers greater range, improved accuracy, enhanced penetration, and significantly increased mapping efficiency for demanding professional applications.
When paired with DJI Terra, DJI Pilot 2, and the broader DJI Enterprise software ecosystem, the Zenmuse L3 provides an integrated workflow from field data collection through point cloud processing and final deliverables. Its ability to capture highly detailed LiDAR and RGB data in a single flight makes it a powerful solution for large-scale surveying, infrastructure inspection, forestry, emergency response, and other complex geospatial operations.
Key Highlights
- High Precision: Achieves vertical accuracy of 3 cm and horizontal accuracy of 4 cm at a 120 m flight altitude. At 300 m, it maintains vertical accuracy of 5 cm and horizontal accuracy of 7.5 cm.
- Exceptional Efficiency: Capable of covering up to 10 km² per flight or 100 km² per day.
- Long-Range LiDAR: Features a 1535 nm LiDAR system capable of detecting objects at up to 950 m with 10% reflectivity at 100 kHz.
- Superior Penetration: Supports up to 16 returns and features a narrow 0.25 mrad laser beam divergence, helping capture detailed ground information through vegetation and detect smaller features.
- Dual 100 MP RGB Cameras: Two 4/3 CMOS mapping cameras provide a combined horizontal field of view of 107°, to capture a wider area with highly detailed imagery during each flight.
- Versatile Scanning Modes: Linear, Star-Shaped, and Non-Repetitive scanning modes allow operators to optimize data collection for terrain mapping, vegetation penetration, urban environments, transmission infrastructure, and complex structures.
