DJI Zenmuse L2 is a high-precision aerial LiDAR system integrating a frame LiDAR, a self-developed high-accuracy IMU system, and a 4/3 CMOS RGB mapping camera, delivering DJI flight platforms with more precise, efficient, and reliable geospatial data acquisition. Achieving 4 cm vertical accuracy and 5 cm horizontal accuracy, covering 2.5 km² in a single flight, and detecting targets up to 450 meters away, the Zenmuse L2 provides a complete turnkey solution for 3D data collection and high-accuracy post-processing when used with DJI Terra.
Frame LiDAR – Powerful Range, Elevated Precision
30% Detection Range Increase
- 250m @10% Reflectivity, 100klx – Reliable detection under bright daylight conditions
- 450m @50% Reflectivity, 0klx – Maximum detection range in zero ambient light environments
- Typical Operational Altitude up to 120m – Significantly enhances both operational safety and efficiency
Smaller Laser Spots, Denser Point Clouds
With a reduced spot size of 4×12 cm @100m — just one-fifth the size of L1 — the Zenmuse L2 detects smaller objects with greater detail and penetrates denser vegetation more effectively, producing more accurate Digital Elevation Models (DEM).
5 Returns & 240,000 pts/s Effective Point Cloud Rate
- 5 Returns Supported – Captures more ground points beneath heavy forest canopies
- 240,000 Points/Second – Maximum point cloud emission rate in both single and multiple return modes
- Up to 100% Effective Point Cloud Data Rate – Frame-based design maximizes data density capture
Two Scanning Modes for Flexible Operations
- Repetitive Scanning Mode – Delivers more uniform and accurate point clouds for high-precision mapping requirements
- Non-Repetitive Scanning Mode – Provides deeper penetration for structural information, ideal for power line inspection and forestry surveying
Frame-Based Design
The frame-based design achieves an effective point cloud data rate of up to 100%. Combined with a three-axis gimbal stabilization system, it unlocks greater possibilities across complex surveying scenarios.
High-Level Precision – Professional-Grade Accuracy
Industry-Leading Geospatial Accuracy
- Vertical Accuracy: 4 cm – Achieved through the fusion of GNSS and DJI’s self-developed high-accuracy IMU
- Horizontal Accuracy: 5 cm – Professional standard for large-scale mapping and survey projects
- Three-Axis Gimbal Stabilization – Maintains sensor stability under all flight conditions
High-Accuracy IMU System – No Warm-Up Required
The Zenmuse L2 IMU system is ready to use the moment it’s powered on. The accompanying drone is ready to begin tasks immediately once RTK reaches FIX status, delivering a significantly optimized field experience with no delays.
