Abstract:
Precise shape reconstruction of archeological artifacts within 0.01 mm 3D resolutions are reported based on our proposal of a practical, accurate, topologically robust and ranging error resistive shape modeling procedure that approximates a real 3D object, with the matrix-format data structure, for the resulting shape processing. Examples of the shape processing are based on the premise of the virtual manipulation of the 3D shape. Radial distance of each scanning point is measured by laser triangulation. A face array listing, which defines the sampling point connectivity and the shape of the mesh, is assigned to meet the desired meshing. Topologically stable meshing, and hence, an accurate approximation, free from the shape ambiguity unavoidable in the so-called ICP (Iterative Closest Point) modeling, is then accomplished. This proposal allows not only the precise shape modeling, but also virtual shape manipulation for various trainings and restorations.
