Removing Vegetation from Point Cloud?

[tog]

Hi, I'm new to CloudCompare but have been very impressed with it's functionality.

One thing I'm trying to do is remove all the vegetation from a vineyard point cloud (ie. create a DTM).

I've tried with the CSF filter with no luck, different scenes and cloth/classification resolutions <1.0

The challenge I think is the regularity of the vineyard rows. Does anyone have any ideas what I could try?

Thanks!

P.S. this is what the point cloud looks like

Hello.

I think a simple way to try the "Rasterize" tool with grid step = interval between rows and cell height = minimum.
