In accordance with some embodiments, systems, methods, and media for estimating depths in a scene using single-photon detectors and binary structured light patterns are provided. In some embodiments, a system comprises: a light source; an image sensor comprising an array including single-photon detectors; a processor programmed to: cause the light source to emit a sequence of n binary light patterns toward the scene, each comprising at least L columns, each of the patterns has a minimum stripe width of 8 columns; and n>log(L); cause, for each of the n binary light patterns, the image sensor to capture a binary image of the scene, the binary image comprises a binary value for each of single-photon detectors such that each of the single-photon detectors generates a set of binary values; and estimate, for each single-photon detector, a depth value based on the set of binary values.
