In the context of cultural heritage, 3D laser scanning and photogrammetric 3D acquisition of broken content is becoming increasingly popular, resulting in large collections of detailed fractured archaeological 3D objects that have to be reassembled virtually. We recently investigated a semi-automatic reassembly approach for pairwise matching of digital fragments, that makes it possible to take into account both the archeologist's expertise, as well as the power of automatic geometry-driven matching algorithms. In order to increase matching efficiency and robustness, we currently focus on shape analysis with higher level representation to guide ICP-like algorithms.
