Can I "batch align" multiple meshes/ a faster way to align 2 meshes

[thiennhan0206]

Dear Daniel

My name is Nhan and Im working on my research project for my final year as a dental student.
Im planning to use CloudCompare as a tool to evaluate accuracy (trueness and precision) of 2 different scanners. Each scanner will make 30 scans. Therefore i will have:
Trueness (compared with reference data): 30 + 30 = 60 comparisons
Precision (comparing two scans from the same scanner) 30C2 + 30C2 = 870 comparisons.
As you can see, i will have to merge 930 times. So I was wondering if there are some features that can help me "batch merge" or "automate merging". If not, is there a way to do this myself?

I would appreciate any feedbacks and/or advice regarding this project.

If the clouds are already roughly registered, then you can probably try to automate things with the command line. You'll have the ability to do automatic registration (-ICP) and compute distances (C2M_DISTS, etc).

See https://www.cloudcompare.org/doc/wiki/i ... _line_mode

There's always a bit of tinkering, but there are plenty of messages on this forum, or you can ask more questions here.
