Projection of tunnel point cloud on a plane

[Massimo]

Hi,
I have never done any scanning inside a tunnel, so I apologize if this may seem a simple question to those who are already experienced in tunnel scanning.
One of my clients asked me to make a scan of a tunnel, and that is not a particular issue.
But what he is asking me, further than providing him with the point cloud, is to provide him with some images (he doesn't need the point cloud in this case) of the tunnel point cloud projected on a plane, as shown in the attached example.
Any suggestion on how to represent the point cloud as shown in the example, is highly appreciated.
Many thanks in advance,
Massimo

I have a same issue with a chimney cone shape that want to unfolded. Th only program that can do it right is the Lupo3d.de point cab and others are not so accurate in the unwrap .
