Detailed 3D reconstruction of large-scale heritage sites with integrated techniques
TLDR
This approach integrates several technologies based on the experience over more than a decade of trying to accurately and completely model large-scale heritage monuments and sites to model a highly detailed structure or site at various levels of detail.Abstract:
Many cultural heritage applications require 3D reconstruction of real-world objects and scenes. Over the past few years, it has become increasingly common to use 3D digitization and modeling for this purpose. This is mainly due to advances in laser-scanning techniques, 3D modeling software, image-based modeling techniques, computer power, and virtual reality. Our approach integrates several technologies based on our experience over more than a decade of trying to accurately and completely model large-scale heritage monuments and sites. Using both interactive and automatic techniques, we can model a highly detailed structure or site at various levels of detail. We use image-based modeling for basic shape and structural elements, and laser scanning for fine details and sculpted surfaces. To present the site in its proper context, we use image-based rendering for landscapes and surroundings. To apply this approach, we created hundreds of models from sites all over the world for documentation, walk-through movies, and interactive visualization. The results were compelling and encouraging.read more

Building a digital model of Michelangelo's Florentine Pieta
TL;DR: The goal wasn't simply to produce the statue's model but also to provide the art historian with material and tools to enable him to answer his own research questions and to develop scanning technology accessible to other cultural heritage projects both in terms of cost and usability.
