Photosculpt http://www.photosculpt.net/ uses 2 pictures to build a model, currently focused on capturing 3d textures rather than an entire model. The developer is working to address full 360 degree capture as well as adding calibration for more accurate data. Right now there is some distortion present in the models, so its probably not best suited for this purpose, but it is something to keep an eye on.

There's a few applications here that are photo based http://www.agisoft.ru/ . One uses multiple images to construct a full 360 degree model, and another that works with image pairs.
