Mass customization for cultural heritage 3D models

Digital technologies in the last twenty years have offered cultural heritage (CH) new possibilities in conservation and promotion. 3D digitization has especially become more and more affordable and efficient. This leads to massive digitization projects and increasing amount of CH digital data. As an engineering team working on industrial techniques for reverse engineering, we are deeply affected by this effect. In this paper we propose a way to combine semantic information on top of the acquisition and modeling steps in order to manage heterogeneous historical data. We illustrate our approach with a use case composed of three overlapping historical objects related to Nantes' harbour history.
