Having worked with this kind of software solutions since the ninties I must say that you should really instead look into the software Photoscan from russian Agisoft (www.agisoft.ru) it's alot more flexible and is very cheap ($129 usd) This was called "Photo Fly" before when it was a "Autodesks Labs project" and I belive the tech originates from when autodesk bought the french software company RealViz that made the software Photomodeler.
