M3C2 - distance uncertainties

[Teresa]

Hi,
I am using the M3C2 algorithm to detect deformations in my point clouds.
I would like to know, how are the distance uncertainties calculated ?
How are they related to the standard deviation ?
Thank you very much !

I think you will have to refer to the article: https://arxiv.org/ftp/arxiv/papers/1302/1302.1183.pdf

(and the wiki if not done already: https://www.cloudcompare.org/doc/wiki/i ... 2_(plugin))
