Extraction of roads

Post by Aubame »

Hi Daniel,
I’m actually working on a project where I have to extract forms and objects from a point cloud.
I’m using CloudCompare, I find the software extremely complete and efficient.
At the moment, I’m trying to extract the roads: I always begin by extracting the ground via the CSF filter, and then with CANUPO, I try to extract the roads.
The problem is that my road has not a “big” density of points in some spots, so it is not considered as road points.
My question is: Is it possible to add points manually in the spots where the problem appears?
Also, have you ever heard of another method for extracting the roads?

Thank you,
Cordially,
Aubame.P

Hum, not really. I believe there's a function to that in the old qPCL plugin (MLS - "Smooth using MLS, optionally upsample").

You would have to segment the low density areas (with the scissors tool), then use MLS on them, and then merge them back.
