COLMAP SfM Data Import

[tworkool]

Hey,
Today I wanted to try and create a dense reconstruction from a custom COLMAP pipeline sparse reconstruction result. COLMAP offers an export tool, which looks like this:

I0329 12:14:41.346447   147 option_manager.cc:849] COLMAP 3.9.1 (Commit e9903641 on 2024-01-08 with CUDA)
I0329 12:14:41.347059   147 option_manager.cc:851] Options can either be specified via command-line or by defining them in a .ini project file passed to `--project_path`.
  -h [ --help ]
  --random_seed arg (=0)
  --log_to_stderr arg (=1)
  --log_level arg (=0)
  --project_path arg
  --input_path arg
  --output_path arg
  --output_type arg          {BIN, TXT, NVM, Bundler, VRML, PLY, R3D, CAM}
  --skip_distortion arg (=0)

As you can see it does not support Meshrooms .abc format for SfM Data.

It would be very nice, I thought, if meshroom supported COLMAP sparse reconstructions out of the box or at least supported the shown formats for SfM Data.
I am not too familiar with Meshroom though and maybe such importer already exists. In that case any tip would be helpful. Thanks!

We have something, but it is not yet ready for release.
