- Record a > 2h video keeping your camera completely still. Use the lowest resolution and FPS setting, as we do not need the video feed for this. In addition, you can cover the lens. A video of a black screen will remain quite small.
- Still this will create multiple video files, so we need to extract the telemetry from each and merge it to a large one.
- Put all video files in a single folder
- Use merge_gopro_telemetry_from_folder.py to concatenate all telemetry files into a single on
- Finally run fit_allan_variance binary on the concatenated telemetry file
- This will give you noise density and random walk values for each axis x-y-z of gyroscope and accelerometer
- Average these values and use them in your favorite VIO or SLAM, e.g. ORB-SLAM3
