Claim 16:
17. One or more computer-readable non-transitory storage media embodying software that is operable when executed by one or more processors of a computing device to:
capture, by a camera of the computing device, and during a time period, images comprising a plurality of detected patterns corresponding to reflections of a plurality of distinct projected patterns projected by a projector, wherein an intensity of each of the plurality of distinct projected patterns varies over the time period in accordance with a predetermined temporal lighting-characteristic pattern associated with the projected pattern, wherein a rate at which the images are captured by the camera is synchronized with a rate at which the intensity varies, and wherein the camera is configured to capture consecutive images over an interval of time corresponding to an interval of time between changes in the intensity of each of the plurality of distinct projected patterns;
determine, based on the images, a detected temporal lighting-characteristic pattern for each of the detected patterns;
detect a correspondence between a first detected pattern of the detected patterns and a first projected pattern of the projected patterns by comparing the detected temporal lighting-characteristic pattern of the first detected pattern to the predetermined temporal lighting-characteristic pattern of the first projected pattern; and
compute a depth associated with the first detected pattern based on the correspondence.
