BOUNDARY-BASED HIGH RESOLUTION DEPTH MAPPING

摘要

Systems and methods which provide generation of high resolution depth maps from low resolution depth information using boundary-based processing techniques are disclosed. Boundary-based depth processing provided by embodiments implements boundary detection and boundary-based interpolation algorithms for providing high resolution depth information from low resolution depth information and high resolution image information. Boundary detection algorithms are implemented according to embodiments to detect object boundaries (e.g., depth discontinuities), where the low resolution depth samples are typically inaccurate and generally in need of refining. Boundary-based interpolation algorithms are implemented according to embodiments of the invention to refine intermediate upsampled depth information (e.g., spatially interpolated low resolution depth information), using the boundary information provided by a boundary detection algorithm, and provide high resolution depth information.
