I have finally released my Structure-From-Motion Toolkit (SFMToolkit). So what can you do with it ? Let’s say you have a nice place like the one just bellow:
|Place de la Bourse, Bordeaux, FRANCE (picture from Bing)|
Well, now you can take a lot of pictures of the place (around 50 in my case):
And then compute structure from motion and get a sparse point cloud using Bundler:
This is the SFMToolkit workflow:
SFMToolkit is composed of several programs:
- BundlerFocalExtractor : extract CCD width from Exif using XML database.
- BundlerMatcher : extract and match feature using SiftGPU.
- Bundler : http://phototour.cs.washington.edu/bundler/ created by Noah Snavely.
- CMVS : http://grail.cs.washington.edu/software/cmvs/ created by Yasutaka Furukawa.
- PMVS2 : http://grail.cs.washington.edu/software/pmvs/ created by Yasutaka Furukawa.
- BundlerViewer : Bundler and PMVS2 output viewer based on Ogre3D (OpenSource 3D rendering engine).
As you can see this “toolkit” is composed of several open-source component. This is why I have decided to open-source my part of the job too. You can download the source code from the SFMToolkit github. You can also download a pre-compiled x64 version of the toolkit with windows scripting (WSH) for easier usage (but not cross-platform): SFMToolkit1.zip.
If you need some help or just want to discuss about photogrammetry, please join the photogrammetry forum created by Olafur Haraldsson. You may also be interested by Josh Harle’s video tutorials, they are partially out-dated due to the new SFMToolkit but these videos are very good to learn how to use MeshLab.
