Abstract
This paper presents a new method for matching individual
line segments between images. The method uses both
greylevel information and the multiple view geometric relations
between the images. For image pairs epipolar geometry
facilitates the computation of a cross-correlation based
matching score for putative line correspondences. For image
triplets cross-correlation matching scores are used in
conjunction with line transfer based on the trifocal geometry.
Algorithms are developed for both short and long range
motion. In the case of long range motion the algorithm involves
evaluating a one parameter family of plane induced
homographies. The algorithms are robust to deficiencies in
the line segment extraction and partial occlusion.
Experimental results are given for image pairs and
triplets, for varying motions between views, and for different
scene types. The three view algorithm eliminates all
mismatches.
