MLS filter / upsampling; tips and tricks; structure scans

[Ferdinand]

Hi all,

I am currently working with structure scans (100M+ points) and a picky meshing tool that I (unfortunately) cannot replace. Therefore, I have to find a way to filter my point clouds in a evenly distributed manner while still maintaining all the important information. After a small parameter study, I have found a set of parameters of removing duplicate points, noise filtering, and SOR which gives me a good result, but still has holes in complicated structures (cables, tubes, etc.) and looks a bit uneven.

This is where I want to use MLS for upsampling the holes and smoothing flat surfaces. However, all of my attempts have gone horribly wrong, resulting in either too much data or holes everywhere. If anyone has worked in a similar way with CC or has any tips, please let me know. Or is this even the wrong approach? Should I try using MLS first or even a different tool?

Thanks in advance.

Not sure how I can help, but I can at least note that the MLS algorithm is a direct port from the PCL library. Maybe you can find other means of calling this library/algorithm, and maybe with more parameters?
