Reconstruction and Visualization of Cultural Heritage Artwork Objects

Abstract

Cultural heritage artwork objects usually consist of multiple surfaces with details that become more apparent over time. The most common deformations concern the composition of materials, the use of objects. Reconstruction techniques are used for building 3D models of existing objects from sensor data such as laser scanner and photogrammetry data. Similarly, we can use additional types of sensor data for reconstructing (i) the micro-structure of the object (dents, bumps, cracks) or (ii) the material layers that lie underneath the external surface. We report on the development of methods for digitally reconstructing and visualizing cultural heritage objects including their material consistency and their micro-structure.
