Abstract
In this paper, we study the problems of estimating relative
pose between two cameras in the presence of radial distortion.
Specifically, we consider minimal problems where
one of the cameras has no or known radial distortion. There
are three useful cases for this setup with a single unknown
distortion: (i) fundamental matrix estimation where the two
cameras are uncalibrated, (ii) essential matrix estimation
for a partially calibrated camera pair, (iii) essential matrix
estimation for one calibrated camera and one camera
with unknown focal length. We study the parameterization
of these three problems and derive fast polynomial solvers
based on Gr¨obner basis methods. We demonstrate the numerical
stability of the solvers on synthetic data. The minimal
solvers have also been applied to real imagery with
convincing results.
