[Qgis-user] IR-airphoto and 3D

[Johan Nilsson]

I have very little knowlight of terminology in this area.

Is there a possibility if you have 2 semi-overlapping IR-photo, with
known flight-altitude, distance between picture, camera-model and
pictures corners coordinat, to make a 3D model with height-data?

To use 2 pictures to get "stereo-vision", requere quite special
dual-screens and gfx-card and polaroid-glasses, so to skip this, are
there some other software that can pick altitude for every pixel in
the area  there 2 IR-photo cover?.

If not QGIS have this, is there any other open source-applications to
use, for instance GRASS that manage this, and what is the name of the
process to make a 3D-map from at leaste 2 airphoto in GIS-terminology?

/Cheers
