Insight3d lets you create 3D models from photographs.

Yesterday while surfing on net I found a interesting freeware software "insight3d" which is a opensource  image based 3 d software


About Insight3d:
 You give it a series of photos of a real scene (e.g., of a building), it automatically matches them and then calculates positions in space from which each photo has been taken (plus camera’s optical parameters) along with a 3D pointcloud of the scene. You can then use insight3d’s modeling tools to create textured polygonal model.

Basically, it hopes to be "Photosynth + Canoma". Or "boujou + Imagemodeler". But it's also free and opensource (GNU AGPL 3). Check out the screenshots below or download it already.

Download insight 0.3.2:

    * Windows Installer (.msi) – in some cases (probably not), it might be necessary to update your system by installing this
    * Linux version – at this point, you can download a standalone archive, but it is necessary to follow the instructions in the README.txt file to compile it on your system

Be sure to read the tutorial!

Disclaimer: This software is intended for educational purposes. Potential users in countries that allow software patents must first investigate whether or not this software package uses any algorithms patented in their respective countries and if so, refrain from using it.

But I need help: there are tons of different digital cameras and I've tested my app only on few of them. insight3d should be able to handle all typical cameras, but there's some stuff in the optimization routines that has yet to be tweaked appropriately. Probably. It would be great if you could send me datasets you tried to feed into insight3d. Both the ones that worked and the ones that didn't are imporant! If you want, download the app, read the tutorial (there's important info on what photos should be used and where to eventually send them!), take some photos, have fun with it and please send it to me. Hope that it'll work for you, but don't hold your breath.
