Abstract
A method for determining a three-dimensional model from two images comprising: receiving first and second images captured from first and second viewpoints, respectively, each image including a two-dimensional image together with a corresponding range map; identifying a set of corresponding features in the first and second two-dimensional images; removing any extraneous corresponding features in the set of corresponding features responsive to the first and second range maps to produce a refined set of corresponding features; determining a geometrical transform for transforming three-dimensional coordinates for the first image to be consistent three-dimensional coordinates for the second image responsive to three-dimensional coordinates for the refined set of corresponding features, the three-dimensional coordinates comprising two-dimensional pixel coordinates from the corresponding two-dimensional image together with a range coordinate from the corresponding range map; and determining a three-dimensional model responsive to the first image, the second image and the geometrical transform.
