That’s going to depend a whole lot on their budget, your capabilities, and the final requirements — is this being used for visuals, or metrology?

I have suggestions for getting visual fidelity but if you’re looking for an explicit 3D model maybe that’s not what you’re going for. (There are new approaches like NeRFs and Gaussian splats that don’t use traditional 3D formats, but look truly great.)

FYI, my colleagues in the past have used Metashape, if you're in the market for an OTS solution. There is also Epic's RealityCapture; I have not used either one, but as far as I can tell capture density and quality matter a lot. For any solve, get good light (outdoors preferred mostly for intensity), and shoot a lot of coverage. If you can use a DSLR (competently) that might help, though today's mobile phones are quite good. If using an iPhone, shoot RAW (Android may have something equivalent?) -- small scale compression artifacts contribute noise to the solve.

And good luck, whatever direction you take this!
