First Claim
1. A computerized method for extracting positional information for a point from a first image and a second image, the method comprising:
- generating a first epipolar line and a first reference line projected in the first image, the first epipolar line corresponding to the point;
generating a second epipolar line and a second reference line projected in the second image, the second epipolar line corresponding to the point;
determining the positional information for the point based on intersecting the first eipipolar line and the first reference line and intersecting the second epipolar line and the second reference line, wherein the positional information includes location information in three-dimensions.

Abstract
A method and system for locating an object in three-dimensional space is provided. In some embodiments, a computerized method for extracting positional information in three dimensions for a point from a first image and a second image is provided. A first epipolar line and a first reference line projected in the first image are generated. The first epipolar line corresponds to the point. A second epipolar line and a second reference line projected in the second image are generated. The second epipolar line corresponds to the point. The positional information for the point is determined based on intersecting the first eipipolar line and the first reference line and based on intersecting the second epipolar line and the second reference line.
