PDF: Spherical Structure-from-Motion for Casual Capture of Stereo Panoramas

Abstract

Hand-held capture of stereo panoramas involves spinning the camera in a roughly circular path to acquire a dense set of views of the scene. However, most existing structure-from-motion pipelines fail when trying to reconstruct such trajectories, due to the small baseline between frames. In this work, we propose to use spherical structure-from-motion for reconstructing handheld stereo panorama captures. Our initial results show that spherical motion constraints are critical for reconstructing small-baseline, circular trajectories.
