Classification: CPC G | IPC G

Claim 11:
12. An apparatus comprising instructions stored on at least one physical storage medium, the instructions, when executed, to cause at least one processor to:
receive 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;
create a first epipolar plane image from the digital values;
process the first epipolar plane image, by identifying a plurality of edges in the first epipolar plane image and fitting a line to the plurality of edges; and
derive 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,

wherein the apparatus further comprises instruction on a physical storage medium that, when executed, are to cause the at least one processor to
receive digital values corresponding to a fourth image from a fourth camera,
create a second epipolar plane image from the digital values corresponding to the first image and the digital values corresponding to the fourth image,
derive a second depth estimate dependent on the second epipolar plane image, and
define a contour in three-dimensional space, dependent on the first depth estimate and the second depth estimate; and

wherein the fourth camera is not located on the first axis within the predetermined threshold.
