Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 1:
2. 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, and
the first camera, the second camera and the third camera are not evenly spaced along the first axis;

wherein the processor-implemented method further comprises
receiving digital values corresponding to a fourth image from a fourth camera,
creating a second epipolar plane image from the digital values corresponding to the first image and the digital values corresponding to the fourth image, and
deriving a second depth estimate dependent on the second epipolar plane image;

wherein the fourth camera is not located on the first axis within the predetermined threshold; and
wherein the contour is dependent on the first depth estimate and the second depth estimate.
