Calculation of Areas of Cultural Relics Surface Defects Based on the Triangular Mesh Model

Abstract:

In order to solve the problem that need exact and scientific data in checking and restoring cultural relics, this paper presents a novel algorithm that statistics defect areas of cultural relics by calculating holes area in the in triangular mesh models.First, build the topological relationship between triangles, vertices and edges and extract boundary using boundary property of triangular mesh. Next, the holes bounding edges are linked in sequence into holes polygon. Finally, distinguish holes boundary and model exterior boundary by means of triangular mesh topological characteristics and the areas of three-dimensional holes polygon are calculated to statistics defect areas of cultural relics through the method of coordinate. Through experiments, it proved that this algorithm was correctly and reasonable.
