From survey to semantic representation for Cultural Heritage: the 3D modeling of recurring architectural elements

The digitization of Cultural Heritage paves the way for new approaches to surveying and restitution historical sites. With a view management integrated programs documentation conservation, research is now focusing on creation information systems where link digital representation building semantic knowledge. reference emblematic case study Calci Charterhouse, also known as Pisa this contribution illustrates an approach be followed in transition from 3D survey information, derived laser scanner photogrammetric techniques, semantically enriched models. proposed based recognition -segmentation classification- elements original raw point cloud, manual mapping NURBS it. For shape process, architectural treatises vocabularies classical architecture key step. created components are finally imported H-BIM environment, they with related knowledge, documentary sources restoration activities.
