Claim 4:
5. A processor-implemented method of creating a contour in three-dimensional space comprising:
receiving digital values corresponding to a first image from a first camera, a second image from a second camera, and a third image from a third camera;
creating a first epipolar plane image from the digital values;
processing the first epipolar plane image, wherein processing comprises identifying a plurality of edges in the first epipolar plane image and fitting a line to the plurality of edges; and
deriving a first depth estimate from the first epipolar plane image, dependent on a slope of the line;
wherein:
the first camera, the second camera, and the third camera are collinear on a first axis within a predetermined threshold,
the first camera, the second camera and the third camera are not evenly spaced along the first axis,
receiving further comprises receiving second digital values corresponding to a fourth image from a fourth camera and a fifth image from a fifth camera,
the processor-implemented method further comprises creating a second epipolar plane image from the second digital values and deriving a second depth estimate dependent on the second epipolar plane image,
the fourth camera and the fifth camera are collinear on a second axis,
the second axis forms a predetermined, non-zero angle relative to the first axis, and
the contour is dependent on the first depth estimate and the second depth estimate.
