If you'll allow a shameless plug: I'm about to publish a python package to help doing just that, by combining photogrammetric projects.
The workflow is take a couple hundred overlapping pictures, compute a model using an existing backend and store the image/3d data. Rinse and repeat. When you have a few neighbouring projects, we recompute submodels at the boundary and merge the involved 3d models by reprojection.
Currently wrangling some issues around packaging, a BSD licensed functional prototype should be out sometime next week.
I'd love to get some users or eyes on it, do get in touch!
