Abstract
Examples are disclosed that relate to methods and systems for determining a depth of a pixel of a depth image. In one example, a method comprises illuminating a scene with amplitude-modulated light of a plurality K of different frequencies. A sensor detects the amplitude-modulated light as reflected from the scene. A plurality K of complex signals k is formed by determining, for each frequency k of the plurality of different frequencies K, a complex signal k comprising a real portion k and an imaginary portion k. A comparison function is used to compare the plurality K of complex signals to a corresponding plurality K of modeled signals, each modeled signal k comprising a modeled real portion k and a modeled imaginary portion k. The method further comprises determining the depth of the pixel based at least on the comparison function and outputting the depth of the pixel.
