> 概要：
> This work introduces the first minimal solvers that jointly estimate lens
> distortion and affine rectification from repetitions of translated or
> rigidly-transformed coplanar local features. The proposed solvers
> incorporate lens distortion into the camera model and extend accurate
> rectification to wide-angle images that contain nearly any type of coplanar
> repeated content. We demonstrate a principled approach to generating stable
> minimal solvers by the Groebner basis method, which is accomplished by
> sampling feasible monomial bases to maximize numerical stability. Synthetic
> and real-image experiments confirm that the solvers give accurate
> rectifications from noisy measurements if used in a RANSAC-based estimator.
> The proposed solvers demonstrate superior robustness to noise compared to
> the state of the art. The solvers work on scenes without straight lines
> and, in general, relax strong assumptions about scene content made by the
> state of the art. Accurate rectifications on imagery taken with narrow
> focal length to fisheye lenses demonstrate the wide applicability of the
> proposed method.
