Piecewise Planar City 3D Modeling From Street View Panoramic Sequences

Free registration required

Executive Summary

City environments often lack textured areas, contain repetitive structures, strong lighting changes and therefore are very difficult for standard 3D modeling pipelines. The authors present a novel unified framework for creating 3D city models which overcomes these difficulties by exploiting image segmentation cues as well as presence of dominant scene orientations and piecewise planar structures. Given panoramic street view sequences, they first demonstrate how to robustly estimate camera poses without a need for bundle adjustment and propose a multi-view stereo method which operates directly on panoramas, while enforcing the piecewise planarity constraints in the sweeping stage.
