Hi,

That docker image is based on ros noetic perception image, so maybe the g++10 was already installed there. To build AliceVision, we should also build its dependencies before here.

And yes, the only usage of AliceVision is for --multiband option in rtabmap-export and related options in Export Clouds dialog in standalone/dbviewer. It refers to texturing approach explained in the link you shared.

You can compare the following reconstruction without multiband and with multiband. I would say that with multiband, the results are very similar to output of photogrammetry (it is normal as Meshroom/AliceVision is a photogrammetry software).

cheers,
Mathieu
