This question already has an answer here:
I have a few pairs of stereo air photos and I want to extract a DEM from them.
I think that is possible using PCI (OrthoEngine), but I would like to do it using Open Source (or at least free) software.
I've looking in GRASS GIS and Orfeo Toolbox but I didn't find how to do it? (It is possible that I have not looked correctly...).
Is it possible?
