I’ve had this problem for long time and just recently figured it out: when uploading my gopro photo timelapses with mapillary tools couldn’t get rid of duplicates (like stopping on street lights). I was using --duplicate_distance command and it didn’t work.
So recently I figured out that I must add --overwrite_all_EXIF_tags and run same command two times to make it work. Probably there are some conflicts between EXIF GOPRO data and .gjson data and what fields is mapillary extracting. Maybe someone could check it out?
Here is my command:
.\mapillary_tools --verbose process --overwrite_all_EXIF_tags --duplicate_distance 2 --duplicate_angle 270 --interpolate_directions C:\mapillary\4\
…and terminal output after processing first and second time. You can spot the difference
