Since the merge above, you can specify the option matching_order_neighbors: 2
to match only images that are consecutive when sorted by image name.
from opensfm.
Assuming you have GPS position of the images on the EXIF, you can set the
option matching_gps_neighbors
to something like 4 to limit every image to
be matched only to the closest 4 neighbors. This uses the GPS position to
determine the neighbors.
Try adding the line
matching_gps_neighbors: 4 # Number of images to match selected
by GPS distance. Set to 0 to use no limit
to the config.yaml
of your dataset.

Thank you for your kind reply.
I don't have GPS position data. I extract sequential images from the omnidirectional video.
Is there any function to match sequential images?
from opensfm.
I just want to bump this, because I'm interested in this, too. Perhaps if we wrote "faked" GPS data to the EXIF header?, but it seems like this should be a core setting, especially for screen grabs from video.
from opensfm.
This would be useful to us too. Images that have come from video have a natural sequence and it would be useful to use this to determine the neighbours instead of GPS position (which is not always available or valid).
I suggest the following three possibilities for passing the sequence number information in.
-
The sequence number could be generated from the exif attribute "Exif.Image.DateTimeOriginal".
-
The sequence number could be taken directly from the exif attribute "Exif.Image.ImageNumber".
-
The sequence number could be embedded within the image file name. E.g. "frame00001.jpg", "frame00002.jpg" etc. in a similar way to that which ffmpeg generates output image file names when given the output name "frame%05d.jpg".
