Hello, I am making 3d reconstructions, orthopotos and DEMs with drones and DSLR cameras for an ancient city excavation project for 3 years. In culturel heritage conservation we need great accuracy and I specialized on using PhotoScan Pro so I know every bit of this software very well. Your attached files' names show that you have at least 900 photos, that requires a good hardware also, which I have right now. I used to do this kind of tasks, you can see it on my profile, so I know how to deal with this project. Thanks.
