Abstract: Aspects of the present disclosure relate to systems and methods for structured light (SL) depth systems. An example method for determining a depth map post-processing filter may include receiving an image including a scene superimposed on a codeword pattern, segmenting the image into a plurality of tiles, estimating a codeword for each tile of the plurality of tiles, estimating a mean scene value for each tile based at least in part on the respective estimated codeword, and determining the depth map post-processing filter based at least in part on the estimated codewords and the mean scene values.

Abstract: Client calibration can include: (a) instructing a host to display a first desired target, (b) imaging the first displayed target, (c) determining a second desired target based on the imaging, (d) instructing the host to display a second desired target, and (e) adjusting a calibration parameter based on one or more images of the second desired target. The second desired target can be determined (e.g., selected, dynamically generated) based on the first desired target.
