Hello, I'm working on two scans of a rough planar surface (granite plate). I did them a month apart and I noticed that the second scan was "bigger" by ~2mm. I wanted to correct it manually and with my basic knowledge I think I need multiply/scale tool however I don't quite understand how i...

When you compute de distance between clouds you get the signed scale with a curve on its side. I wanted to be sure about what it refers to. I assume it shows the concentration of the points on the scale? If yes is it a simple [n°point/part of the scale] or is there some other equations applied to it...

My clouds is not that dense ( 16 point / unit^2) so I will work with meshes.

Thanks a lot!

I used Delaunay after trying to carefully register them. However further tests showed that if worked with mesh instead of clouds I got better result. I suppose that meshes tend to not be affected by noise as much as cloud.

Thank you!

Hello, after registering and merging 4 clouds sharing partial coverage and meshing the result I ended up with something like the one attached. top right : no coverage bottom right : 2 coverage bottom left : 4 coverage I don't know what I messed up. When I Register and merge the separate mesh it does...

I got a new question so I'm updating this thread since it is similar. When it comes to ICP, meshes takes more time to register but what are the pro and con of using C2C, C2M and M2M for registration? How can I compare them with my models to see what gives the minimum error? I've read the ICP doc but...

Thank you! I managed to do several trials and it seems that either C2C-quadratic and C2M are the best for my project.

But in the case of 'merge', the aim was to minimize the amount of memory used And it is very thoughtful. However it would be nice to have a tickbox like "merge as new cloud" for when you work with small point clouds. Beside What you might actually do is clone it before merging so in the e...

I'm really confused about the way CC manage project. Why can't CC automatically generate a new cloud from a process? You merge 2 clouds and it changes one of the two instead of giving you a new merged-cloud (I'm really confused since segmenting tool DO provide you with a new cloud). The fact that yo...

I'm currently doing basic distance calculation between two set of two merged scan and I'd like some advice. What are the main pro/con of choosing CloudvsCloud, CloudvsMesh or MeshvsMesh when it comes to registering/comparing 2 scans? I noticed that Meshes are far more timeconsuming but seems to give...
