Description

The Zenmuse L1 integrates a Livox Lidar module, a high-accuracy IMU, and a camera with a 1-inch CMOS on a 3-axis stabilized gimbal. When used with Matrice 300 RTK and DJI Terra, the L1 forms a complete solution that gives you real-time 3D data throughout the day, efficiently capturing the details of complex structures and delivering highly accurate reconstructed models.

Highlights

Frame Lidar with up to 100% effective point cloud results
Detection Range: 450m (80% reflectivity, 0 klx) / 190 m (10% reflectivity, 100 klx)
Effective Point Rate: 240,000 pts/s
Supports 3 Returns
Line Scan Mode and Non-repetitive Scan Mode
20MP
1-inch CMOS
Mechanical Shutter
Accuracy: 0.025° (roll/pitch) / 0.08° (yaw)
Vision Sensor for Positioning Accuracy
GNSS, IMU, RGB Data Fusion
Real-time point clouds provide immediate insights onsite, so operators are informed to make critical decisions quickly.
You can also verify fieldwork quality by checking point cloud data immediately after each flight.
Acquire and communicate critical dimensions on the point cloud model using measurements and annotations.
DJI Terra fuses the IMU and GNSS data for point cloud and visible light calculations, in addition to conducting POS data calculations so you can effortlessly generate reconstructed models and accuracy reports.
