Automatic culture relic fragment splicing method based on adaptive neighbor matching

Abstract

The invention discloses an automatic culture relic fragment splicing method based on adaptive neighbor matching, which belongs to the field of computer graphics and image processing. The method comprises steps: firstly, a culture relic fragment feature line is used to depict the geometric texture of the fragment surface and the contour line of a fracture site; then, in view of different points onthe fracture contour line, different local adaptive neighbors are generated, wherein a neighbor contains the surface geometric texture and the surface color texture of the culture relic fragment at the same time, and thus, matching of fracture site contour lines is expanded to matching of fracture site contour bands; and finally, through matching of the fracture site contour bands, the adjacency relationship of the culture relic fragments is determined, and adjacent fragment splicing is completed by using rigid body transformation. According to the automatic culture relic fragment splicing method based on adaptive neighborhood matching, multiple features on a culture relic fragment can be effectively fused, and in view of a defect fragment existing in the fracture site, the automatic degree is high, and the result accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of computer graphics and image processing, and relates to an automatic splicing method of cultural relic fragments based on adaptive neighborhood matching. Background technique [0002] Cultural relics are relics and relics with historical, artistic and scientific value created by human wisdom and labor in the development and evolution of historical society. They represent the cultural heritage and wisdom crystallization of a nation, and also symbolize the economic, political The development level and trend of science, technology and culture provide reliable basis and precious materials for contemporary people to understand and study history. Therefore, the protection of cultural relics is very important. Since the 1990s, with the explosive development of information technology, especially the research and rise of digital photography technology, optical scanning technology, virtual reality, multimedia and o...
