auto-trace polyline from linear point cloud
Posted: Wed Sep 18, 2019 3:09 pm
Specific aim
Auto-create a polyline (to be used in profile extraction) from a simple set of points that mark the centre of this would-be line.
General aim
I want to extract some profile sections along the length of curved cylindrical shape that are perpendicular to the length of the object.
Current workflow is to extract cloud sections at small intervals along a straight line on my area of interest.
then.
Batch export the cloud info to file - this gives me a point file that maps to the median line of the shape.
then
I want these points turned into a polyline to use for wider-spaced profiling along this mid-line.
There are too many to trace polyline by hand.
I think I probably want to smooth this mid line too?
I think I can do it quickly in another 3D program, but would prefer to keep it to cloudcompare or cloudcompare+text editor if possible.
Am I missing something obvious?
Does this sound a like a plausible approach or am I going to get myself in a mess?
Many thanks in advance.
