A Fast and Automatic Hole-Filling Method Based on Feature Line Recovery

Chunhong Xia, Hui Zhang, Tsinghua University

Abstract. With the fast development of data acquisition equipment, it becomes much easier to get the three dimensional representation of a real object. Nevertheless, due to constraints of the equipment and surrounding conditions, the digital data acquired is usually incomplete and contains defects. As a result, the triangulated mesh model always contains self-intersections, gaps, and holes, and might bring errors to following process or applications. Self-intersections can be solved by adding and deleting mesh faces based on topology, gaps can be filled by simply connecting different parts together. The problem is how to deal with holes properly. Holes usually appear at unexpected areas and always have complex boundaries and topology. What’s worse, the shape of the missing part is unclear. In this way, hole-filling plays a challenging and indispensable role in the fundamental process of 3D models.
