Non-rigid Alignment?

[Andy99]

Hi Everyone,

I am looking for an option for non-rigid alignment of mobile laser scans (GeoSLAM ZEB) does anyone know if that’s possible in CC or in any other software?

We have scanned the interior and exterior of a long service depot (250m+) with a GeoSlam ZEB scanner and ended up with large errors and it seems that it is impossible to align the individual scans correctly.

I also have some overlapping data from a NavVis scanner and a good photogrammetry (exterior only) data from what seems to be correct - they have aligned nicely - but they don’t cover everything and I would really need some of the GeoSLAM scans to fill the missing parts.

I wonder if there is a method to "warp" the non-accurate GeoSLAM point clouds to a reference cloud coming from other sources on a non-rigid way?

The only 'non rigid' option in CC is to allow the scale to change (you have an 'adjust scale' option in both the ICP and the Point-pair based alignment tools).

Otherwise, I don't know any other option.
