Stepping Up My Photogrammetry

This is my first attempt at capturing a life size object, Cabin Run Covered Bridge in Bucks County, PA, and turning it into a photogrammetry model. I took a total of 136 images of the bridge from all angles. What I was not able to do however was capture the corners of the bridge do to the trees. This caused a problem when modeling because I was not able to join the sides of the bridge to the entrances. This is why the model data breaks down when I spin it to view from the entrance views.
