ICP with rotation limited to Z returns identity matrix

[hamishharvey]

Hi,

In the research tab for ICP registration, there is an option to limit rotation to a particular axis. I'd like to allow rotation about Z (up) only, because I have two clouds that are already levelled.

I find that no matter how good (or bad) the initial registration, is, if I do this I always get the identity matrix back. Is this expected?

Is there any way to achieve a registration in CC that allows 3 axis of translation, and only one of rotation?

Thanks!

Not sure, It's a long time since I tried this. Those are old options (and by 'research' we mean that it's not stable / validated enough to be used by standard users). And I confirm that it's apparently broken...

We'll have to fix this!

I'd like to +1 the ability to constrain rotation to a single axis, or disable it entirely. We're trying to evaluate reconstruction geometry after correcting for vertical and horizontal offsets (due to position uncertainty) and would prefer to limit ICP registration to translation only.

This still seems to be broken but would be very useful. Any update on getting this fixed?

Not that I am aware of!
