Abstract
A method for determining a three-dimensional model for a scene comprising: projecting a sequence of binary illumination patterns onto a scene; capturing a sequence of binary pattern images of the scene from a plurality of capture directions; projecting a sequence of periodic grayscale illumination patterns onto the scene, each periodic grayscale pattern having the same frequency and a different phase; capturing a sequence of grayscale pattern images from the plurality of capture directions; determining a range map for each capture direction by analyzing the captured binary pattern images and the captured grayscale pattern images; and determining the three-dimensional model for the scene responsive to the range maps determined for each capture direction.
