Interactive reassembly of fractured fragments based on feature points of contour line
摘要
Abstract
A novel interactive method which can assemble the fractured fragments was proposed based on the surface pattern breakpoint and feature points on contour line of the fracture fragments.Firstly,the geometric structure and contour line were obtained by generating Laplacian lines,and pattern breakpoints and feature points were selected.Then,the combination for distance of feature points to pattern breakpoint,the inner angles and distance of adjacent feature points can produce feature descriptors which determine the adjacency relationship between fragments.All the pairwise points were searched through matching function.Finally,the quaternion outputed the rigid transformation matrices,then two fragments were precisely aligned based on optimal rigid motion through exhaustive search.The experimental results indicate that the reassembly time with13% to 16% saved and result errors are less than 1 mm.The method can reassemble fractured fragments efficiently and successfully.关键词
