Abstract
A system and method for acquiring geometric information from images includes a modulated light source configured to provide light energy at a rate unperceivable by the human eye. A camera is configured to acquire images at a rate at which a differential pair of images is obtained such that one of the pair of images includes light from the light source and the other image of the pair does not include light from the light source. A comparison module is configured to compare the differential pair of images to create a depth map for three-dimension model creation.
Claims19
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.

- a comparison module configured to compare the differential pair of images to determine geometric information for said object;
- and
- a frame selection module configured to eliminate frames illuminated by the modulated light to provide a sequence of images not illuminated by the modulated light.
