Point Cloud LiveView

Real-time point clouds give immediate insights onsite, so operators are informed to make crucial decisions swiftly.

You can also verify fieldwork exclusivity by checking point cloud data immediately after each flight.

Measurement and Annotation

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

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 simply and effortlessly create reconstructed models and precision reports.

The DJI Zenmuse L1 is a cost-efficient and easy and quite simple to use enterprise aerial LiDAR payload, engineered for DJI’s flagship commercial drone, the M300 RTK. The L1 integrates a Livox sensor, high-precision IMU, a one-inch 20MP CMOS visual camera with mechanical shutter, and 3-axis stable gimbal system.

DJI L1 Additional Features:

Payload Health Management System: Built into the DJI Pilot app, the Payload Health Management System records the total use time of the DJI L1, as well as the number of rotation times, error logs, and product maintenance suggestions.

Real-time Awareness Flight: The LiDAR sensor can acquire the aircraft’s height above the ground in real-time and perform a terrain awareness flight to verify data quality and flight safety.

Precision Report: After the flight, DJI Pilot will create a inspection report, view the quality of the point-cloud data, the photo position, number of photos, and the RTK status, so the pilot can confirm the quality of the data on-site

Generate Accurate Models And Reconstructions:

The DJI L1 is focused at commercial drone users who are looking for high-precision aerial surveying solutions. The LiDAR sensor can empower clients in energy, AEC, public safety, architecture/heritage, and forestry management. The L1 is ideal for the following scenarios:

-Topographic Survey: Collect elevation data in a compact vegetation field. The L1 is able to extract Digital Elevation Models (DEM) and Digital Surface Models (DSM).

-Infrastructure Reconstruction: Reconstruct highly-detailed structures such as power lines, and oil and gas pipelines to lesson manned operations – improving efficiency and increasing safety.

-Forestry: Due to the multi-echo capability of the DJI L1, the elevation data in dense forest fields can be easily generated and extracted into DEM and DSM.

-Emergency Mapping Survey: The DJI L1 is capable of capturing real-time, true colour point-cloud models. This -provides up to date information for emergency response teams. The IP44-rated L1 can also operate in rainy/foggy conditions, as well as low-light scenarios.

Harness The Power Of The DJI Ecosystem:

Operators can utelize the DJI ecosystem for an end-to-end LiDAR surveying workflow. This involves the M300 RTK, the L1 sensor, DJI Terra, and the DJI Pilot app.

-UAS Platform: DJI M300 RTK drone and L1 payload.

-Ground Control App: DJI Pilot (able to generate point clouds in real-time).

-Post-processing Software: DJI Terra (professional version or above).

-Data Output: 3D point cloud in .LAS format.

Data Acquisition: Plan mission using DJI Pilot app, with a collection of mission options available. Make sure the M300 RTK is connected to RTK network, otherwise DJI Terra will not post-process the captured data.

Data Process: In DJI Terra ‘Aerial Photography’ task, select the mapping scene as ‘LiDAR post-processing’, and then choose the source folder containing LiDAR IMU and Inertial Navigation Data to start data processing. If the chosen folder contains visible light photos, the generated point-cloud file is a visible light point cloud.
