Extract polyline from point cloud

Hi,
I have this section slice of a point cloud:
- pointcloud_sectionslice.jpg (43.54 KiB) Viewed 25657 times
Is there a way to auto generate polyline(s) tracing the center of the point cloud formations (maybe based on point density or 2d surface geometry)? I know how to extract the concave hull contour from the Section Cut menu, but I will only get the outer contour.
Thank you.

Sorry, I'm not sure to understand what you are trying to extract here... Can you maybe outline/draw it on the image?

I have this scan segment of a niche:
- niche_segment.jpg (79.73 KiB) Viewed 25550 times
I will cut out a slice of this niche and manually trace the center of the point cloud with a polyline:
- niche_slice.jpg (111.04 KiB) Viewed 25550 times
The resulting polyline looks like this:

I would like to know if it is some how possible to automate this process (of tracing the center of the point cloud slice with a polyline) with cloudcompare?

And you don't manage to do that with the Cross Section tool? (
