Noise Filter

[ichbinBer]

Hello! I have issues with my lidar scan, and there are low noise being classified as "non-ground" when they should have been classified as "ground." I used the noise filter but I'm not sure how to get the exact parameters to completely remove the noise. Do you guys have any recommendations for that? Thank you!

I guess you try to use CSF? (if yes, make sure to use the latest 2.13 version as the algorithm has been improved).

And then, regarding the Noise cleaning or SOR filters, it's generally a trial and error process to set the parameters correctly. But in the end it's always a trade-off between how much noise you are willing to remove against how much good points you are ready to loose!
