Single-view reconstruction from an unknown spherical mirror

Abstract

This paper introduces a novel method for 3D reconstruction from spherical mirrors in a single view. Traditional reconstruction algorithms either assume both intrinsic and extrinsic parameters of the cameras being known precisely and rely on multiple view information to recover 3D objects, or use reflections of the 3D objects on spherical mirrors with known radii in a single calibrated view. It will be shown in this paper that 3D objects can be recovered up to a scale using an unknown spherical mirror in a single view. Experimental results on both synthetic and real data show the practicality of the proposed reconstruction method.
