How to delete single points that can't be isolated with segmentation tool

[boocaj]

I have to clean a rockwall dense cloud to remove the vegetation and the noise. I already did the big job with the segmentation (scisor) and the SOR tools, but there a few random points off the wall that I am not able to isolate (find an angle of view with no other points at the back) to be able to segment them.

So my question is: Is there any way to juste delete single points one by one by clicking on each one of them? Because those single points off the wall are giving me bad results when I apply a M3C2.

Thanks in advance!

Not as you described, but have you tried the 'Label Connected Components' tool? It's generally a good way to remove isolated clusters of points (see https://www.cloudcompare.org/doc/wiki/i ... Components). You can merge all the large clusters back together at the end of the process.

Another option is to use the latest 2.13.alpha version that lets you set near and far clipping planes even during the segmentation process (that can help to view/access the 'hidden' points).
