George, thanks for the feedback. I will look what LAStools can do, it seems interesting.
Another possible approach I've tested briefly is to select data using the RGB value, it's not perfect and a lot of "segmentation" of the data would have to be done, but it can work (sort of)

General / Trees!

Hi!

I'm testing Photoscan for mapping purposes and the goal for now is to get an accurate DEM, in order to extract important features (road edges, buildings, etc) and also obtain ground contours.
My test area has plenty of trees and I wanted to know if anyone has experience on removing this "noise" from models / point cloud, as I require only the surface for the contours.
I wanted do know if anyone has experience with this (apart from masking every photo) Any pointers?

Thanks in advance.
