タイトル:    Degereneracies in Rolling Shutter SfM

アブスト:
We present the problem of degeneracies in Structure from Motion (SfM) with 
rolling shutter cameras.  We first show that many common camera configurations, 
e.g. cameras with parallel readout directions, become critical and allow for a large 
class of ambiguities in multi-view reconstruction.  Then, we provide mathematical 
analysis of some multi-view cases and related synthetic experiments and show that 
bundle adjustment with rolling shutter cameras, which are close to critical configurations, 
may still produce drastically deformed reconstructions.  Finally, we provide practical 
recipes how to photograph with rolling shutter cameras to avoid scene deformations 
in SfM.
