Estimate point scattering perpendicular to a facade

Hi Everyone.

I’ve recently modelled a water tower with a pretty good result. As the lightning was difficult and the texture of the building very smooth, i got some little noise on some part of the facade.

I was wandering if anyone know a good way to asses the scattering of the points perpendicular to the surface. This would help me asses the quality of the reconstruction.


We do not do any statistical analysis of those outliers in Pix4Dmapper. Maybe other Community users have an idea about how to do this in other software.
Here you can find more information about how to delete these points in Pix4Dmapper: How to edit the point cloud in the rayCloud.
I hope it helps!

Cloudcompare has pretty good SOR-filter. You should give it a try. Best of all it’s open source.
