Image processing system and method

摘要

An image processing system comprises a first video camera arranged to have a first width of field of view, and operable to capture a first image, a second video camera arranged to have a second width of field of view narrower than that of the first video camera, and operable to capture a second image substantially at the same time that the first camera captures the first image, and an image processing unit operable to access scene geometry for a known scene, with the first video camera and the second video camera being arranged in a pre-set positional relation to each other; the image processing unit is arranged in operation to map scene geometry onto the first image captured by the first video camera, and the image processing unit is arranged in operation to map onto the second image captured by the second video camera at least part of the scene geometry mapped onto the first image, in dependence upon the pre-set positional relation of the first and second video cameras and their respective widths of field of view.

1. An image processing system, comprising:
a first video camera arranged to have a first width of field of view, and operable to capture a first image; a second video camera arranged to have a second width of field of view narrower than that of the first video camera, and operable to capture a second image substantially at the same time that the first camera captures the first image; and circuitry configured to access scene geometry for a known scene; and in which: the first video camera and the second video camera are arranged in a pre-set positional relation to each other; the circuitry is configured to map scene geometry onto the first image captured by the first video camera; the circuitry is configured to store predetermined correction factors for relative optical distortions between the first image and the second image for a plurality of zoom levels of the second camera; the circuitry is configured to map onto the second image captured by the second video camera at least part of the scene geometry mapped onto the first image, in dependence upon the pre-set positional relation of the first and second video cameras, their respective widths of field of view, and the predetermined correction factors; and the circuitry is configured to graphically augment the second image based on the scene geometry mapped onto the second image to display the second image with additional information superposed on the second image.
