Abstract:
1. An image processing system for integrating multi-resolution images using a plurality of multi-resolution image capture devices to extract images from an observed scene, and using a plurality of multi-resolution imaging devices to present a scene image relative to the observed scene, comprising: an imaging plane; a wide-angle image capture device, for capturing the observed scene according to a first resolution and producing a wide-angle image; a Pan-Tilt-Zoom (PTZ) image capture device, for capturing the observed scene according to a second resolution, a designated direction, and a focal distance and producing a Pan-Tilt-Zoom image, wherein the second resolution is higher than the first resolution; a fixed imaging device, for presenting a processed wide-angle image on the imaging plane according to a third resolution, wherein the processed wide-angle image has at least one reserved region without image information; a steerable imaging device, for presenting a processed Pan-Tilt-Zoom image on the imaging plane according to a fourth resolution, wherein the processed Pan-Tilt-Zoom image is only presented in a region corresponding to the reserved region of the processed wide-angle image, wherein the fourth resolution is higher than the third resolution; a conversion module, for converting the Pan-Tilt-Zoom image to a conversion image which is in a coordinate system of the wide-angle image capture device based on an image capture device conversion matrix (homography; H an imaging module, for applying the fixed imaging device to present the processed wide-angle image on the imaging plane according to the third resolution, and applying the coordinate system of the steerable imaging device to present the processed Pan-Tilt-Zoom image on the imaging plane according to the fourth resolution based on an imaging device conversion matrix (H wherein said image processing system further comprises: an imaging corrected pattern module for the fixed imaging device and the steerable imaging device to respectively present a corrected pattern; a corrected pattern acquisition module for the Pan-Tilt-Zoom (PTZ) image capture device to capture the corrected patterns presented in the fixed imaging device and the steerable imaging device and to respectively obtain a corrected image; a conversion matrix module, for calculating a first extraction imaging conversion matrix (H an imaging device conversion module, for obtaining the imaging device conversion matrix (H
