Warnings
1. The ZENMUSETM L2 has been calibrated specifically for the designated camera and lens
before leaving the factory. No physical or mechanical modification or adjustment of the
gimbal is required or recommended. DO NOT add any other component or device to the
camera such as a filter or lens hood.
2. Only use the L2 with specified compatible DJITM aircraft. Make sure the firmware of the
aircraft and the remote controller are the latest versions.
3. DO NOT expose the LiDAR to strong sources of energy such as a laser beam or any other
LiDAR in use. Otherwise, the LiDAR may be permanently damaged.
4. Be careful when using the L2 in conditions with low visibility such as foggy or stormy weather
as the detection range may be reduced.
5. DO NOT touch the optical window of the L2. Dust and stains on the optical window can
negatively affect the performance. Use compressed air, isopropyl alcohol, or a lens cloth to
clean the optical window correctly. Refer to the L2 User Manual for more information on how
to clean optical windows. DO NOT use substances containing alcohol, benzene, thinners, or
other flammable substances to clean or maintain the RGB mapping camera.
6. DO NOT drop the L2. Calibrate the L2 using DJI TERRATM if the point cloud data is inaccurate
or the output is layered.
Introduction
The Zenmuse L2 integrates a LiDAR module, a high-accuracy IMU, and an RGB mapping camera
on a 3-axis stabilized gimbal, which can be used with specified compatible DJI aircraft. With
Point Cloud LiveView, users can take a quick view of the 3D point cloud effect in the DJI PILOTTM
2 app. When used with DJI Terra, the L2 offers a complete solution that generates point cloud
output and extracts ground points to generate DEM results, which efficiently completes highly
accurate reconstructed models of complex structures.

Installation (Figure A)
• To ensure the mapping accuracy, make sure the L2 is mounted on a single
downward gimbal connector with the cable connected to the right USB-C
port (when facing the aircraft).
• Make sure the gimbal connector on the aircraft is positioned correctly when
mounting. Otherwise, the L2 cannot be mounted.
• Only remove the L2 after powering off the aircraft.
• Remove the L2 by pressing the button on the aircraft to detach the gimbal
and camera.
• Make sure the microSD card slot cover is firmly in place to prevent dust or
moisture entering during usage or transportation.
• To avoid burns, DO NOT touch the camera case and the optical window
when powering on.
• Detach the gimbal from the aircraft during transportation or storage.
Otherwise, the service life of the damper balls may be shortened or they
may even be damaged.

Mission Flight
Users can create a flight mission to record point cloud data in DJI Pilot 2 and import the
recorded data into DJI Terra for high-precision model reconstruction.
Getting Started
1. Make sure the L2 is correctly installed on the single downward gimbal connector of the
aircraft, and that the aircraft and remote controller are linked after powering on.
2. Go to camera view in DJI Pilot 2, select and then Precise Positioning Setting. Choose the RTK
service type, and make sure that the status of RTK positioning and heading both display FIX.
3. Adjust the camera parameters on the upper right corner of camera view according to the
surroundings. Make sure the photo is well exposed. Tap to switch exposure modes. It is
recommended to set Auto mode for recording point cloud data.
Recording Point Cloud Data
To record point cloud data, create a flight mission or begin a manual flight. The following uses
an Area Route as an example.
1. Enter the camera view in DJI Pilot 2 and tap , select Create a Route, and then Area Route.
Tap on the map view, and drag the boundary point to adjust the range of the mapping area.
2. Choose the aircraft, and then select Zenmuse L2, LiDAR Mapping. Set the Payload Settings,
Advanced Settings, and other parameters. It is recommended to set the Side Overlap (LiDAR) to
above 20%, the Scanning Mode to Repetitive, the altitude to 150 m, the flight speed to 15 m/s,
and to enable Calibrate IMU.
3. Tap to save the task and tap to upload and execute the flight mission.
4. Power off the aircraft after the mission is completed and remove the microSD card from the
L2. Insert the microSD card into a computer and check the point cloud data and other files in
the DCIM folder.
• Read the Zenmuse L2 User Manual for more information about setting parameters for
Photogrammetry missions, and recording point cloud data with Mission and manual flights.

1. Launch DJI Terra and select New Mission. Then create and save a point cloud post-processing
mission.
2. Select in the mission editing view and import the folder from the microSD card. The folder
will be named according to the time the first point cloud data was recorded.
3. Click to start reconstruction and wait until it is completed.
4. Open the current mission folder to check the result of the reconstruction.
• Read the DJI Terra User Manual for more information about how to configure and use

[1] Measured using a flat target with a size larger than the laser beam diameter, perpendicular
angle of incidence, and with an atmospheric visibility of 23 km. In low-light environments,
the laser beams can achieve the optimal detection range. If a laser beam hits more than one

11
EN
target, the total laser transmitter power is split and the achieveable range is reduced.
[2] The accuracy was measured under the following conditions in a DJI laboratory environment:
using an Area Route mission with Calibrate IMU enabled in DJI Pilot 2, and using repetitive
scanning with the RTK in the FIX status. The relative altitude was set to 150 m, flight speed to
15 m/s, gimbal pitch to -90°, and each straight segment of the flight route was less than 1500 m.
Choose objects with obvious angular features for data collection. DJI Terra was used for post-
processing with Optimize Point Cloud Accuracy enabled. If not enabled, the vertical accuracy is
4 cm and the horizontal accuracy is 8 cm.
[3] Measured in an environment of 25° C (77° F) with a target of 80% reflectivity at a distance of
150 m. The actual environment may differ from the testing environment. The figure listed is
