[ Reconstruct scene like Photosynth ]

Is there any open source code which does similar to MS Photosynth

Photosynth is a potent mixture of two independent breakthroughs: the ability to reconstruct the scene or object from a bunch of flat photographs, and the technology to bring that experience to virtually anyone over the Internet.

Using techniques from the field of computer vision, Photosynth examines images for similarities to each other and uses that information to estimate the shape of the subject and the vantage point the photos were taken from. With this information, we recreate the space and use it as a canvas to display and navigate through the photos.

Providing that experience requires viewing a LOT of data though—much more than you generally get at any one time by surfing someone’s photo album on the web. That’s where our Seadragon™ technology comes in: delivering just the pixels you need, exactly when you need them. It allows you to browse through dozens of 5, 10, or 100(!) megapixel photos effortlessly, without fiddling with a bunch of thumbnails and waiting around for everything to load. About this Release

Photosynth comes from a passionate little startup of two dozen people in Microsoft Live Labs. We are scientists, engineers, and designers working like crazy to deliver on Photosynth’s promise.

Answer 1

The closest thing I've found to an open source Photosynth is Insight3D. It can be found here: http://insight3d.sourceforge.net/ While parts of Insight3D are open source and it can be downloaded for free, there are libraries included that are not open source such as the SIFT feature detector.

Bundler ( http://phototour.cs.washington.edu/bundler/ ) may also meet your needs. Bundler is very connected to Photosynth ( http://phototour.cs.washington.edu/ ) It requires a bit more to get it running. It doesn't have any GUI and has to be compiled.


I have an update to report in the area of open source structure from motion applications. OpenMVG is a photo reconstruction project that is being actively developed (https://github.com/openMVG/openMVG). It contains reusable libraries as well as a series of executables that comprise the various step of a photo reconstruction pipeline.

Update 2

Mapillary has released a structure from motion project called OpenSfM. https://github.com/mapillary/OpenSfM. It has a some sweet features such as:

  • Support for panoramas
  • Sensor fusion with GPS and accelerometers
  • An example implementation of a web viewer

Answer 2

You could just try a few queries on Google before posting a question.

Answer 3

Have a look at Hugin . It is not what Photosynth does but it is a pretty powerful opensource for creating panoramic images.
