Patent Images

1. A method of obtaining distance data from 2D images of a scene comprising one or more objects, said method comprising:

  • projecting on the objects a coded light pattern comprising multiple appearances of a finite set of feature types, each feature type being distinguishable according to a unique bi-dimensional formation, such that a distance between adjacent epipolar lines associated with substantially identical appearances of any given feature type is minimized according to a limiting epipolar separation factor, giving rise to a plurality of distinguishable epipolar lines separated by approximately a minimum safe distance for epipolar line distinction;

    capturing a first image and a second image of the objects having the projected coded light pattern projected thereupon, such that along an epipolar line in each of the first and second images the projected pattern provides a non-repeating artificial texture;

    finding a given pixel area in the first image along a matching epipolar line in the second image.
