Sphere detection RMS threshold

Post by rdurr »

We use the sphere detection option in the point pair picking registration tool. Our scanning device has relatively high range noise and we often get a
[ccPointPairRegistrationDlg] RMS is too high! message.

Is it possible to change the RMS threshold value?

Good idea. I added a new field to the Align tool. You can download the latest beta version online to test this (should be ready in a few minutes).

I´d like to use the sphere fitting by a given radius. Might this be possible?

Not right now. I know someone had hacked the qRansacSD tool to add a constraint on the sphere radius, but he has never sent me the code :(

It was not very hard if I believe him.

Hi Daniel,

Do you have some update about sphere fitting since 2016? I can see on tool-fit-sphere an automatic algorithm but I would like to give a specific radius.
Best regards,

Sylvain Gautier

It doesn't seem someone was motivated enough to do this (even though it shouldn't be too complicated - I say that in case you have some minimal development skills ;).
