Gap filling

Post by T1230321 »

Hi everyone,

Complete novice here.

I'm wanting to fill some small gaps I have in my scans. Could someone tell me the best way to do this, please?

I have seen other forum posts discussing the topic by using plugins, but I'm not sure how, or where, to get these from.

Any help would be much appreciated.

Some info:

Scanner - FARO X330
Scans processed in Faro Scene and exported as ASCII file
Corresponding xyz file imported into CloudCompare.

Thanks

I guess the only reliable way to do this is to mesh the cloud (at least locally) with one of the 2 meshing approaches (Delaunay or Poisson - see https://www.cloudcompare.org/doc/wiki/index.php/Methods and https://www.cloudcompare.org/doc/wiki/i ... n_(plugin)) and eventually sample points on the resulting mesh.

But frankly, that looks quite painful ;)

- draw plolyline around the hole
- sample polyline into points(1000 points)
- mesh the new points
- sample mesh into points
- merge new points into scan points
- delete extra ployline and mesh etc

Hi DA523,

Thanks very much for your reply.

I followed that up until point 5.

How do you go about merging the new points into scan points? The 'merge' option is greyed out for me.

Thanks in advance
