Date: 2017/10/9             Browse: 30

Speaker:   Prof. Tomas Pajdla

Time:        Oct.  9 ,  10:00  –  11:00

Location:  Auditorium, SIST Building

Inviter:     Prof.  Jingyi Yu 


We will present two problems related to 3D reconstruction with rolling shutter (RS) cameras. First, we will show how one can generalise the classical absolute camera pose problem, also known as P3P, to cameras with RS. Since RS is more complex projection model, we will introduce linearization of the model to obtain a tractable algebraic problem. Second, we will present an analysis of degeneracies in 3D reconstruction with rolling shutter cameras. We will 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. Finally, we will provide some practical recipes how to photograph with rolling shutter cameras to avoid scene deformations.
