Photosynth Point Export - Photosynth as a 3D Scanner?

Take a look at the movie below and make sure you watch it all the way through - note the export of the model from photosynth into a stand alone 3D package:

This opens up the possibility of using photosynth as a free 3D scanner, and one that would work on objects up to the building level scale. It seems to be early days but there is a lot of discussion going on around the tutorial here.

If anyone has any more insight do let us know via the comments...


  1. A bit offtopic but perhaps interesting as well:
    One fact about psynth is the need for quite a lot of pictures of the object or scene in the first place. A nice workaround (apart from grabbing public images from flickr) is using a hd-camera and cutting the video into frames to go on with the psynth-processing.

  2. That's an interesting point - so just film around an object in HD, save as frames and upload.

    Do you have any examples?


  3. There is another free web service called Arc3D that exports point-cloud models from digital photos without that much hacking. It's at

  4. Actually I just tried it once - on myself ;-)
    You`ll find the synth on my blog The video was done in 1024x768 at 15 fps.

  5. Arc3D is interesting, we have been meaning to give it a try so now is a good chance - we will post some thoughts soon as we get chance.

    The synth is impressive - 1024x768 seems to work really well.

  6. I`m testing ARC3D at the moment with some shots of the manhattan skyline. Going to post some results as soon as I have them.
    Perhabs DU could do a post or two about MS Image Composite Editor and Seadragon? In my opinion that`s two really impressive technologies for getting fast and accurate panoramas and a good access to 50mp+ pictures:
    BTW: It was just a fire in a local factory - looks far more impressive than it actually was.
