Hi Götz,
Yes, I only removed the GPS data :). I decided to start from scratch and added a bunch of control point which helped after rerunning the reconstruction overnight. Unfortunately, that led to the white box having half of the front and top missing, so I added some more control points for all the surfaces that were not looking great and am rerunning since about 10am PST. I should have something to show in about 2 hours (2:15).
Related, I was looking at other parts of the UI and was thinking about Image>Show Matches. When I turn it on, I noticed that a lot (if not most) of the match points between two given photos seem to be the gravel ground around the unit.
I’m wondering if it would be better or worse to select a reconstruction area that doesn’t include the ground? Any thoughts?
