    In recent years, the determination of global image orientation, i.e. global SfM, has gained a lot of attentions from researchers, mainly due to its time efficiency. Most of the global methods take relative rotations and ...
  • Reich, Martin; Heipke, Christian (Göttingen : Copernicus GmbH, 2016)
    In this paper we propose a novel workflow for the estimation of global image orientations given relative orientations between pairs of overlapping images. Our approach is convex and independent on initial values. First, ...
  • Chen, Lie; Rottensteiner, Franz; Heipke, Christian (Katlenburg-Lindau : Copernicus Publications, 2020)
    Matching images containing large viewpoint and viewing direction changes, resulting in large perspective differences, still is a very challenging problem. Affine shape estimation, orientation assignment and feature description ...
  • Wang, X.; Rottensteiner, F.; Heipke, C. (Göttingen : Copernicus GmbH, 2018)
    In this paper we present a novel approach for image orientation by combining relative rotations and tie points. First, we choose an initial image pair with enough correspondences and large triangulation angle, and we then ...
