Reshaping the Coliseum in Rome: an integrated data capture and modeling method at heritage sites

The paper describes the process of building Internet-transmittable, 3-D digital virtual models of ancient heritage monuments from on-site data, focusing especially on 3-D dimensional data acquisition techniques and color processing methods. Section I considers project goals and the attendant problems; Section 2 provides a brief summary of state-of-the-art experience and the technologies adopted by the Authors; Section 3 illustrates the key features of the 3-D color data acquisition methods used as well as the shape and color processing pipeline; Section 4 describes the specific study conducted on single elements and facades of the Coliseum in Rome, while Section 6 outlines future work.
