Abstract: To match the images of larger parallax change,blocked or linear fracture,this paper proposed a multi-level line matching method based on and multiple constraints.Firstly,constraint of the linesegment in the neighborhood with matched reliable seed points to accomplish point-line matching is based on seed points;Next,perform of the line-line matching within geometric feature constraints is based on homography matrix and epipolar line constraint;Finally,we completed line matching with line-surface matching using a adaptive linear similarity constraint method.Experiments show that this method can accurately match images of larger issues,blocked or linear fracture and solve the problems that existing line matching algorithm has lower accuracy and unable to fulfil large parallax changing.
