Triangulation of Points Constrained to a Plane
Petr Hrubý, Elima Shehu
We study the set of image tuples arising from fixed cameras observing varying planar 3-dimensional point configurations. We derive a formula for the number of complex critical poin…
Single-View Rolling-Shutter SfM
SofÃa Errázuriz Muñoz, Kim Kiehn, Petr Hruby +1
Rolling-shutter (RS) cameras are ubiquitous, but RS SfM (structure-from-motion) has not been fully solved yet. This work suggests an approach to remedy this: We characterize RS sin…
Minimal Solvers for Full DoF Motion Estimation from Asynchronous Tracks
Petr Hruby, Marc Pollefeys
We address the problem of estimating both translational and angular velocity of a camera from asynchronous point tracks, a formulation relevant to rolling shutter and event cameras…
Single-Scanline Relative Pose Estimation for Rolling Shutter Cameras
Petr Hruby, Marc Pollefeys
We propose a novel approach for estimating the relative pose between rolling shutter cameras using the intersections of line projections with a single scanline per image. This allo…
