computer and check the .txt format log file. The calibration is successful if All succeed is
displayed. Users can also record the point cloud data to check whether the time parameter
of the .CLI le is updated.
Restoring the Internal and External Parameters to Default Settings
If the calibration results are not satisfactory, the internal and external parameters can be
restored to the default settings by following the steps below.
1. Create restoring les
a. Restoring the .CLI le: create a new .txt le and name it clear_user_extri_params.txt.
b. Restoring the camera parameters: create a new .txt le and name it reset_cali_user.txt.
Open the le and write the serial number of the L2 that will be reset with the format SN
number: XXXXXXXXXXXXXX. The serial number is located in the .CLI le and can be viewed
in the device version information in the app.
2. Import the file: copy the .txt file that needs to be restored to the root directory of the
microSD card, insert the microSD card into the L2 that needs to be calibrated, install the L2
onto the aircraft. Power on the aircraft and wait approximately 5 minutes for calibration to
complete.
3. Record the point cloud data and remove the microSD card from the L2. Insert it to a
computer and check the .txt log le. The calibration is successful if All succeed is displayed. It
is also possible to check whether the time parameter of the .CLI le is restored to the default
settings.
4. If restored successfully, delete the restoring .txt les from the microSD card.
