A New Algorism of Matching Line Segments
Qifeng Yu · Journal of National University of Defense Technology · 2008
Line segments are ordinary in man-made targets and matching line segments is the first step in a lot of fields,such as 3D reconstruction.Because of occlusion,the question of matching individual line segments is difficult to figure out with the traditional methods,and a novel approach based on epipolar-line constraint and the RANSAC algorithm is presented.Firstly,the points on line segments between image pairs are matched by epipolar-line constraint;Secondly,the RANSAC algorithm is used to estimate a straight line model fit to a set of 2D points,so the line segments of occlusion is matched availably.The result of the synthetic and real images is accurate and reliable.
