Hello together!
In my projects I have to do with laser scanning in tunnels. From the measured point clouds I have to create horizontal ground views as well as vertical longitudinal sections and cross sections. I can generate the ground views and cross sections very easily by creating sections within the toolbox "Point cloud extended" - "Sections". This also works with longitudinal sections as long as the section line is a straight line, because then it is only a parallel projection of the point cloud in the XZ- or YZ-plane.
But now my question: for the creation of a longitudinal section along a broken intersection line I actually need to wind off the point cloud along this broken path. A simple parallel projection is not sufficient, otherwise the longitudinal section will be shortened. Is there a workflow for this?An additional problem is that the tunnel profiles are very irregular, as they are historical mining. This means that there is no horizontal ceiling and floor or no vertical walls.
I am looking forward to any hints! Thank you very much.
