Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for detection of pixel correspondences in stereo imaging through the use of polarization data. One of the methods include: obtaining a first image from a first viewpoint of a stereo pair and a second image from a second viewpoint of the stereo pair; obtaining an angle of linear polarization (AOLP) map and a degree of linear polarization (DOLP) map having a field of view overlapping the first image and the second image; computing a surface normal map based on the AOLP map and the DOLP map; and detecting corresponding pixels between the first image and the second image by computing a disparity map that minimizes an energy function comprising a pixel matching cost term and a polarized smoothness regularization term computed based on pixels in a local neighborhood and based on the surface normal map.
