In this thesis we focus on reconstruction and segmentation of cultural heritage based on photogrammetric point clouds. We present the methodology of archaeological 3D
documentation on land and underwater, state-of-the-art reconstruction and segmentation techniques, and prepare an overview of use cases and current issues in computer science in archaeology. We updated Segmentor, a tool for segmentation with superellipsoids, ported it into a library and included it as a plugin in 3D modelling tool Meshlab, a well established tool for 3D modelling. We implemented a supervised method of creating initial seeds for segmentation and a global deformation method for superellipsoids, suitable for modelling amphoras and similar artifacts. We reconstructed a dozen of superellipsoids from 3D models of archaeological sites and of different amphoras accessible on the web.
