Digitize without Compromising

Exceptional Efficiency - Generate true-color point cloud models in real-time, or acquire 1.24 mi² of point cloud data in a single flight using the Livox frame Lidar module with a 70° FOV and a visible light camera with a 1-inch sensor.

Ready When You Are - The IP44 rating allows the Zenmuse L1 to be operated in rainy or foggy environments. The Lidar module’s active scanning method enables you to fly at night.

Unparalleled Accuracy - Render centimeter-accurate reconstructions thanks to the high-accuracy IMU, a vision sensor for positioning accuracy, and the incorporation of GNSS data.

Point Cloud LiveView

Real-time point clouds provide immediate insights in the field, so operators are able 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.


Measurement and Annotation

Acquire and communicate critical dimensions on the point cloud model using measurements and annotations.
