Large scale dataset

Can I use Meshroom on large datasets with more than 1000 images?

Yes, the pipeline performance scales almost linearly. We recommend adjusting the SfM parameters to be a bit more strict, as you know that you have a good density / good connections between images. There are 2 global thresholds on the Meshing node (maxInputPoints and maxPoints) that may need to be adjusted depending on the density/quality you need and the amount of RAM available on the computer you use.

Can I use Meshroom on renderfarm?

Meshroom has been designed to be used on renderfarm. It should be quite straightforward to create a new submitter, see the available submitters as examples. Contact us if you need more information to use it with a new renderfarm system. Details: https://github.com/alicevision/meshroom/wiki/Renderfarm-submitters

Nodes that can be computed in parallel on multi-machines are:

FeatureExtraction (CPU)
FeatureMatching (CPU)
DepthMap (CUDA GPU)
DepthMapFilter (CPU)
