Structure and Motion from Unordered Image Collection
Introduction:
Inspired by the excellent previous work Photo Tourism and "How do I organize my holiday snaps?", I am currently trying to build a similar large baseline structure from motion system and improve the performance. Here is the slides (.ppt) I made for UVa graphics seminar (may help to give you a quick review of the basic idea).
Preliminary result:
Input image collection (12 unordered images):
Some matching pairs after RANSAC based refinement:
Some trackings across multiple pictures:
Reconstructed Motion (not robust yet):
More results on a larger dataset (35 stereo image pairs):
(you can see each stereo pair of images are grouped together)
