Mission Planning with the Zenmuse L1/L2 for Lidar and Photogrammetry

This article covers the basics of planning lidar and photogrammetry missions with the DJI M300/M350 drone and Zenmuse L1/L2 sensor. 

Lidar is a great option if a ground model is needed for a vegetated area. These specific settings will cover recommendations for data capture in vegetated areas, but different settings may be needed depending on the environment.

1. To begin, power on the controller to access the DJI Pilot 2 app.

2. Connect to a WiFi network or hotspot to ensure base maps will load to assist with mission planning.

3. From the DJI Pilot 2 main menu, tap Pilot 2.


4. Tap Flight RouteDJIPilot2_FlightRoute.png

5. Tap the + at the top-right and select Create a Route.


6. Select Area Route.


7. Locate your site by panning around the map and using two fingers to adjust the zoom.

8. Drop a pin to start creating your survey area by tapping on the screen on the boundary of your site.

To move a pin, tap and hold to select it and drag the pin around with your finger. You can delete the selected pin by tapping the trash icon or by double-tapping on the pin.


9. After points are dropped to define the mission's boundary, tap the check mark at the top-left. If the settings don’t appear, tap the double arrows at the top-right portion of the screen to expand them.


10. Navigate through the settings listed below to set up your mission. Remember that our recommendations differ somewhat between the L1 and L2 sensors.





11. After you have inputted all the settings, tap the save icon.


Before flying the mission, please review our ground control recommendations. If AeroPoints are used for ground control, photos must be submitted with your lidar data.

L1 Photogrammetry

The Zenmuse L1/L2 can also be used for standard photogrammetry without lidar. For the best results, we recommend flying distinct lidar and photogrammetry missions rather than combining the data collection in a single flight.

Begin by creating a route as outlined above in steps 1 through 9.

1. Once your mission boundary has been placed, select the L1/L2 Camera Model and Photogrammetry Lens.


2. Adjust the settings based on our recommendations listed in the table below. If you encounter settings in the app not mentioned in this table, leave them at their default.


 3. Tap the save icon to save your settings.


4. Navigate to the camera settings by tapping the live camera view. The map and camera view will switch places.




5. Adjust the camera settings as described in the table below. When you encounter settings in the app not mentioned in this table, leave them at their default.

Note that in winter, or low light conditions, there are special considerations to make. You may need to slow down the flight speed of the craft (to less than 10m/s) and adjust the shutter speed to 1/800 or 1/500 to allow enough light to hit the sensor.

Failure to do this can result in a high ISO and will reduce the quality of the images you capture.

6. Double-check your settings in the Preflight Checklist and ensure Dewarping is turned ON for best results. The Preflight Checklist will appear when you start your mission.

Check the airspace on your site before you arrive, and remember to charge your AeroPoints and drone batteries before your mission.
