  • The new GPMF parser is able to extract more useful information (e.g. GPS fix and GPS precision) for fixing the noisy GPS issues.
  • Also we use the video time clock to keep the video and its GPS track in sync, so users don't need this flag anymore --interpolation_use_gpx_start_time. This change also fixes Images sampled from GoPro split videos repeat the timestamps for each video segment #505
  • By default it removes GPS points with GPS fix == 0 or DoP precision > 1000 as they are considered as noisy. Users can configure these settings by these envvars: e.g. MAPILLARY_TOOLS_GOPRO_GPS_FIXES=0,2,3 MAPILLARY_TOOLS_GOPRO_MAX_GPS_PRECISION=100000
  • A test CLI is provided for extracting GPX from the GoPros python3 -m tests.cli.gpmf_parser /path/to/gopro.mp4. You can visualize the output in https://gpx.studio/
