METHOD AND APPARATUS FOR SYNTHESIZING HIGH-RESOLUTION IMAGERY USING ONE HIGH-RESOLUTION CAMERA AND A LOWER RESOLUTION CAMERA

摘要

An apparatus and method for transforming imagery recorded by one camera into other imagery that differs from the first imagery, using imagery collected by one or more additional cameras that differ in their characteristics or parameters from the first camera. Example differences include spatial position of the camera, spatial resolution, spectral characteristics and spatial layout. The apparatus generates a synthetic high-resolution image using a high-resolution camera (206) positioned and a lower-resolution camera (208). The high-resolution image data is warped using the lower-resolution data to generate a synthetic high-resolution image (114) having viewpoint of the lower-resolution camera (208). The high-resolution synthetic image generation routine (110) comprises the steps of correcting the spatial, intensity and chromanence distortions of the image data acquired from the high-resolution camera (206) and the lower resolution camera (206) (step 202), subsequently filtering and subsampling the corrected high-resolution data (step 210), computing the parallax between the high-resolution data and the low-resolution data (step 212) and warping the high-resolution image to create a synthetic image (114) of the scene (200) having a viewpoint of the lower-resolution camera (208) (step 214).
