Because of the number of cameras (c. 1000) and the limited capacity of my computer, I am building a model of a stone building in chunks. I have successfully aligned chunks of several portions of the structure using camera positions, however I am having difficulty aligning one room interior. To connect the room with the exterior, I included 14 photos from the exterior around the doorway to the room in the room chunk. Alignment etc. went fine, all aligned properly. However, when I then attempt to align this chunk using cameras, nothing happens.
Any ideas where I might be going wrong? Why might the align fail technically?
