Zenmuse L1

INSTANT CLARITY. SUPERIOR ACCURACY.

A Lidar + RGB Solution for Aerial Surveying

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. Some Key Features – Integrates a Lidar module, an RGB camera, and a high-accuracy IMU, High Efficiency 2 km covered in a single flight, High Accuracy  Vertical Accuracy: 5 cm / Horizontal Accuracy: 10 cm, Point Rate: 240,000 pts/s, Supports 3 Returns, Detection Range: 450 m (80% reflectivity, 0 klx), IP44 Ingress Protection Level & Point Cloud Live View. The 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.

One-stop Post-processing

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.
