Enhanced object reconstruction
First Claim
1. A method for determining three-dimensional information, the method comprising:
- identifying a single reference element created by a fixed pattern projected onto a three-dimensional object in each of two images, the fixed pattern including a background region, an element, and the single reference element, wherein the element and the single reference element are distinct from the background region, and wherein the single reference element is distinct from the element;
determining a correspondence between portions of the two images based on the single reference element created by the fixed pattern;
determining three-dimensional information about the three-dimensional object based on the correspondence between the portions of the two images; and
generating a three dimensional surface model using the three-dimensional information based on projection of only the fixed pattern onto the three-dimensional object.

Abstract
Processing images includes projecting an infra-red pattern onto a three-dimensional object and producing a first image, a second image, and a third image of the three-dimensional object while the pattern is projected on the three-dimensional object. The first image and the second image include the three-dimensional object and the pattern. The first image and the second image are produced by capturing at a first camera and a second camera, respectively, light filtered through an infra-red filter. The third image includes the three-dimensional object but not the pattern. Processing the images also includes establishing a first-pair correspondence between a portion of pixels in the first image and a portion of pixels in the second image. Processing the images further includes constructing, based on the first-pair correspondence and the third image, a two-dimensional image that depicts a three-dimensional construction of the three-dimensional object.

26. A method for determining three-dimensional information, the method comprising:
-
identifying a non-repeating reference element created by a fixed pattern projected onto a three-dimensional object at a single position in each of two images, the fixed pattern being fixed relative to a light source that is projecting the fixed pattern, the fixed pattern including a first portion having a first repetitive component created by light projected from the light source and a second portion having a second repetitive component created by an absence of light projected from the light source, wherein the non-repeating reference element is distinct from the first portion and the second portion; determining a correspondence between portions of the two images based on the non-repeating reference element created by the fixed pattern; determining three-dimensional information about the three-dimensional object based on the correspondence between the portions of the two images; and generating a three dimensional surface model using the three-dimensional information based on projection of only the fixed pattern onto the three-dimensional object at the single position. - View Dependent Claims (27)
