Edit/clean Point Cloud - Remove concrete, steel and vegetation

[rdale]

I am new to CC and have a point cloud that I wish to clean. I have attached a screen capture. My interest is the rock face and rockmass structure and I would like to remove the concrete and steel structures as well as the vegetation, so i can do some stereographic analyses of the rockmass. I have spent some considerable time looking for a way to do it and was hoping a colour select, or even a picking tool was available. I did try what I hoped would work, working with colours, but didn't have much luck.

Thanks in advance.

Removing vegetation this way (with RGB information) is not super easy / clean.

I would rather use:
- the classification approach (with the CANUPO plugin) but it might ask for some time to tame the beast
- or use the 'roughness' measure (as I would expect the rock to be a little less 'fuzzy' than the vegetation)

You can also send me the file if you want me to test things more thoroughly (admin [at] cloudcompare.com)
