You might want to check out Computer Graphics (The Proceedings of the
Association for Computing Machinery's Special Interest Group on
Computer Graphics (aka SIGGRAPH)) from the early 1990s.  I remember a
paper on creating 3D models from (flat) aerial photographs.  They had
some impressive images based on photos of Pasadena (I think).  They
derived the stereo data by measuring shadows (and a few other
methods).  I can't remember if they re-rendered the photos
stereoscopically.
