Abstract:
Depth camera systems and methods of operation use coded structured light to determine depth values. One example method includes projecting a structured light pattern towards a target region. The structured light pattern includes a plurality of parallel bars that encode a plurality of codes. The method includes, for each of a plurality of rows of pixels that are transverse to the plurality of parallel bars: decoding the plurality of parallel bars represented in the row of pixels to identify a location of each of the plurality of codes in the row of pixels; determining a plurality of disparities respectively between the identified locations of the plurality of codes and a plurality of reference locations respectively associated with the plurality of codes; and determining a depth value for each identified location based at least in part on the determined disparity for such location.
