Affine Correspondences between Central Cameras for Rapid Relative Pose Estimation

no code implementations • ECCV 2018 • Ivan Eichhardt, Dmitry Chetverikov

This paper presents a novel algorithm to estimate the relative pose, i. e. the 3D rotation and translation of two cameras, from two affine correspondences (ACs) considering any central camera model.
