Rectification with Visual Sphere perspective: an algebraic alternative for P4P pose estimation

Jakub Maksymilian Fober

Presented algorithm solves co-planar P4P problem of parallel lines viewed in perspective with algebraic equation. Introduction of visual sphere perspective model extends this algorithm to exotic non-linear projections, where view angle can span to 180{\deg} and beyond; a hard-limit of rectilinear perspective used in planar homography. This algorithm can perform full 3D reconstruction of visible rectangle, including pose estimation, and camera orientation. Full pose estimation requires some camera-lens information like angle of view (for rectilinear projection) or a perspective map. In case of generic 2D perspective-correct rectification, camera lens information is not required for this method.
