Extracting point clouds from Photosynth
Tom Goskar
some software that easily extracts point clouds from Photosynth:
http://pspcexporter.codeplex.com/ (Windows only)
While the point clouds that I have extracted thus far have been
disappointing, at least this might make it easier to experiment with.
Cheers,
Tom

Have you checked out this 'Bundler' library? I haven't given it a go -
but it looks like it may be the open-source equiv. of Photosynth (in
fact Photosynth may have been based on some of it I think I read
somewhere).
It would be interesting to see if anyone has looked at it? http://phototour.cs.washington.edu/bundler/
