I am using a GoPro 4 for recording pictures in time lapse mode with a frequency of 0.5s.
For recording the gpx track I am using my smartphone with OsmAnd and a frequency of 1s.
For processing the gps data into the images and uploading to mapillary I am using the mapillary commandline tools.
Not sure if the GoPro in general is able to write subseconds.
At least I found unprocessed images without them, but processed images with subseconds - so I guess the subseconds are added by mapillary tools?
Similar to what is mentioned in this thread: What's wrong with my subsecond sequences?
We assume to have pictures with subseconds now. Are the mapillary tools able to interpolate the gpx positions as wells? Since we have two pictures now for each gpx timestamp, both are usually placed on the same location and the second one gets a heading to the north instead of the directions of movement (to the next picture).
Thanks for your support,
