1. A method for acquiring geometric information of images, comprising: illuminating an object with a structured pattern at a modulated rate unperceivable by the human eye; capturing, by a camera, images of said object at a frame rate at which a differential pair of images is obtained such that a first image of the pair of images is illuminated and a second image of the pair of images is not illuminated, wherein the frame rate that said images are captured is higher than said modulated rate; comparing the differential pair of images to determine geometric information for said object; and implementing a frame selection process to recover a sequence of images that were not illuminated, wherein said sequence of images that were not illuminated are used for the reproduction and display of a scene.
