Hello,
I am wondering if there is some tool for GRASS or another OpenSource application that is able to take two Photos, of differing zoom lengths of a surface and produce a 3D DTM.
I am probably not explaining this well, but here is an example - with downloadable brochure of examples…

Thanks!

An old module exists that does stereographic derivations:

Wow, this is really interesting, I just downloaded the source and pre-read the tutorial you sent me too.
Has anyone used this module at all?
I’ll try getting this to work on my Mac, any guidance building this to work with OS X, Williams Framework builds of GRASS would be appreciated!
I’ll keep you posted.
cheers!

Haven't tried it, still (lack of time and no really need, but sounds
like fun). Please drop a line if/how it works.
