The reason might be because that bug was fixed not long ago, but the fix is still not part of the latest release. Maybe try installing Norfair from the master branch:
pip install git+https://github.com/tryolabs/norfair.git@master#egg=norfair
Tell me if this fixes the issue.

If you want to avoid having that warning (so that you always estimate the transformation), you can also try setting the max_points
argument of the MotionEstimator to a higher value (so that it tries sampling more points), or the min_distance
argument to a smaller value (so that we allow to sample points that are closer to each other).

Thanks a lot, @aguscas !
Installing from master seemed to work. I do get the following warning though:
Does this mean that transformation will be skipped for the frame in case of this issue but everything else will work fine?
from norfair.
Everything should work fine. That means that the coord_transformation
will not be updated in that frame (the MotionEstimator
will return the latest transformation it could estimate). As long as that doesn't happen often it shouldn't be a problem with the coord_transformation
, since typically a single frame shouldn't affect that much at the coordinate_transformation
.

Makes sense! Closing this issue. Again, thanks so much for your help!

For now, it's not an issue for me but I'll experiment with those two parameters. Thanks a lot!
