Abstract
An apparatus includes a memory configured to store multiple sets of image data. Each of the sets corresponds to a respective portion of a surface of an object and a respective portion of a structured light pattern projected onto the surface. The apparatus includes a processor configured to perform structured light reconstruction of the sets, including matching a first group of image pixels that correspond to a projected pixel of the structured light pattern in a first set of image data with a second group of image pixels that correspond to the projected pixel in a second set of image data. The processor is configured to perform stereo reconstruction of the sets, including matching one or more features detected within the first group of image pixels with one or more features detected within the second group of image pixels, to generate three-dimensional point data of the surface.
