Abstract
In an image processing system having a primary image pickup device and a plurality of reference image pickup devices, a feature region consisting of a plurality of feature segments each defined by a pair of feature points is extracted from a primary image. Subsequently, a correspondence point candidate of each of the feature points is extracted from each of the reference images. Based on the feature points and the correspondence point candidate of each of the feature points for each of the reference images, three-dimensional coordinates corresponding to the feature points are calculated, and the feature region is extracted as a target object from the primary image based on the feature points and the three-dimensional coordinates corresponding to the feature points for each of the reference images.
