Semi-Global Matching (SGM) is a widely-used efficient
\nstereo matching technique. It works well for textured
\nscenes, but fails on untextured slanted surfaces due to its
\nfronto-parallel smoothness assumption. To remedy this
\nproblem, we propose a simple extension, termed SGM-P, to
\nutilize precomputed surface orientation priors. Such priors
\nfavor different surface slants in different 2D image regions
\nor 3D scene regions and can be derived in various
\nways. In this paper we evaluate plane orientation priors derived
\nfrom stereo matching at a coarser resolution and show
\nthat such priors can yield significant performance gains for
\ndifficult weakly-textured scenes. We also explore surface
\nnormal priors derived from Manhattan-world assumptions,
\nand we analyze the potential performance gains using oracle
\npriors derived from ground-truth data. SGM-P only
\nadds a minor computational overhead to SGM and is an
\nattractive alternative to more complex methods employing
\nhigher-order smoothness terms.<\/p>\n","protected":false},"excerpt":{"rendered":"
