How to implement on costumized dataset?

[zhejia01]

The position and pose calibrated by COLMAP will lead to no convergence on costumized dataset.

Can you share the dataset? I've had decent results on every CO3D & COLMAP dataset I've tried (although I haven't shared the COLMAP reconstruction code here, I could put it over on leonidk/fmb-plus ).

Typically the core problem is that this works with a few initial conditions (which most captures satisfy):

• scene should be outside-in object reconstruction.
• scene needs to be rescaled to appropriate scale, or else mean/prec gradients dominate optimization
• initialization should be at the center of focus

This repo is a little older, and maybe the results in https://github.com/leonidk/fmb-plus/ or https://github.com/leonidk/ns-fmb would be easier to run/debug/compare.
