This package is now very old. (things have moved really fast!) I recommend using Changchang Wu’s VisualSFM, which works splendidly and continues to incorporate new research.
Last week I held a workshop on Photogrammetry and Augmented Reality. As preparation for the workshop, I took the fantastic BundlerMatcher tool by Henri Astre, and packaged in a few tools to make it as simple as possible to use.
The Bundler Photogrammetry Package can be downloaded from http://files.neonascent.net/SFM.zip. A guide to using it is available at http://files.neonascent.net/photogrammetry-guide.pdf.
The package is a combination of a number of different programs and packages, along with some script of my own. The main advantage at the moment of this approach over Astre Henri’s other tool; PhotoSynth Toolkit, is that you can break image-sets into chunks to process in higher detail without crashing/running out of memory.
