Brief description

Several vision tasks rely upon the availability of sets of corresponding features among images. We present a method which, given some corresponding features in two stereo images, addresses the problem of matching them with features extracted from a second stereo pair captured from a distant viewpoint. The proposed method is based on the assumption that the viewed scene contains two planar surfaces and exploits geometric constraints that are imposed by the existence of these planes to predict the location of image features in the second stereo pair. The resulting scheme handles point and line features in a unified manner and is capable of successfully matching features extracted from stereo pairs acquired from considerably different viewpoints. Experimental results from a prototype implementation demonstrate the effectiveness of the approach.

Sample results

Left image of the 1st stereo-pair	Right image of the 1st stereo-pair		Left image of the 2nd stereo-pair
Point matches in the left image of the first stereo pair		Point matches in the right image of the first stereo pair
Resulting matched points at the distant, left image of the second stereo pair	Reconstruction of scene and camera geometry based on the extracted correspondences: side view		Reconstruction of scene and camera geometry based on the extracted correspondences: top view
