Terracotta Reassembly from Fragments Based on Surface Ornamentation Adjacency Constraints

Abstract

This paper introduces a method that enables the reassembly of fragments with incompleteness in fracture surfaces and break-curves. The incompleteness of the fracture surfaces and break-curves, both contribute to the failure of all previous geometry-driven techniques for reassembly of 3D objects. The proposed method is preferable because it depends on the surface ornamentation-the structured feature lines, which are often complete and can provide enough surface adjacency constraints. Finally, we demonstrate the benefits of our method with the favorable results for real-world point clouds of Terracotta.
