Parallax correction for partially overlapping stereo depth images

Abstract:

Improved techniques for generating a depth map are disclosed herein. Initially, a stereo pair of images comprising a first and second image are obtained. Both an overlap region and a non-overlap region are identified as between these two images. A depth map is generated based on the stereo pair of images. Generating this depth map is performed by determining, for the overlap region, depths for a portion of an environment represented by the overlap region via stereo matching. The generation process is also performed by determining, for the non-overlap region, depths for a portion of the environment represented by the non-overlap region by acquiring depth information from a source different from the stereo pair of images.
