Title:
IMAGE PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO2000046751
Kind Code:
A3
Abstract:
In a method of processing first and second stereo pairs of images (IL, IR; IL', IR') of an object (3), imaged by a stereo rig, a first ordered distortion map (D-MAP 1) of the local geometric transformations required to map regions of one image (IL) of the first pair onto the corresponding regions of the other image (IR) of that first pair and a second distortion map (D-MAP 2) of the local geometric transformations required to map regions of one image (IL') of the second pair onto the corresponding regions of the other image (IR') of that second pair are generated. At least some regions of the first and second distortion maps are correlated to register at least one image (IL) of the first stereo pair with at least one image (IL') of the second stereo pair. Gruen's algorithm can be used to generate the distortion maps and for the correlation.
