Claim 18:
19. A system for image analysis, the system comprising:
a first imaging device, having a first FOV, and located at a first, initially unknown position;
a second imaging device, having a second, different FOV, and located at a second, initially unknown position, and wherein the relative location and orientation between the imaging devices is unknown;
a non-transitory memory device, wherein modules of instruction code are stored, and at least one processor associated with the memory device, and configured to execute the modules of instruction code, whereupon execution of said modules of instruction code, the at least one processor is configured to:
receive a first image of a scene from the first imaging device, and receive a second image of the scene from the second imaging device;
calculate a plurality of flow lines in the first image, wherein each flow line represents an optical flow between a pixel of the first image and a corresponding pixel of the second image; and
calibrate at least one of the first imaging device and second imaging device, to obtain an origin point in a plane of the first image, said origin point defining convergence of a plurality of epipolar lines, each representing an optical flow between the first image and the second image; and
match one or more pixels in the first image with one or more corresponding pixels in the second image by searching the one or more corresponding pixels along an epipolar line of the plurality of epipolar lines.
