Zenmuse L1 – A Lidar+RGB Solution
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.
Measurement and Annotation
Acquire and communicate critical dimensions on the point cloud model using measurements and annotations.
Point Cloud LiveView
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.
