Multiple volume calculations

[Piroddi]

I have a point cloud with multiple individual stockpiles as seen in the example image. Is there a way to calculate the volume of each stockpile individually without having to first isolate a pile first? Can a plugin be created such that the process is automated and all volumes are generated at once?

Currently there's no such option.

And I guess it would be possible to isolate each 'pile' during the volume calculation process (with a standard 'connected components' extraction algorithm) but I wonder how clean the result would be? It all depends on the resolution and density of your data...

Thanks for the help. The data has a ground sampling distance (GSD) of 3.8mm. Does cloudcompare have a connected components algorithm?

Thank you

Well it does but it's meant to be used on 3D point clouds. In your case it would be more interesting to use it on the 2.5D difference raster (which is used to compute the volume). Each pile could be isolated by ignoring differences below a certain threshold and then applying the connected components extraction on the raster.

Of course it would imply some developments, but that doesn't seem impossible at least.
