Orthophoto mapping and digital surface modeling for archaeological excavations. An image-based 3D modeling approach
(The Eurographics Association, 2013)We have examined image-based 3D modeling for the generation of orthophotos and digital surface models of archaeological surfaces and features. Our results suggest that image-based 3D modeling can be both a time-efficient ... -
On the 3D Documentation of the Igel Column Original and Copy. Structured 3D Survey and Analytical 3D Information System
(The Eurographics Association, 2013)The Igel Column, 23 m high, is one of the best known Roman column monuments in Germany and is part of the UNESCO World Heritage 'Roman Structures, Cathedral and Church of Our Lady' in Trier. The list also includes a ... -
Cultural heritage documentation using geomatic techniques; Case study: San Basilio s monastery
(The Eurographics Association, 2013)Each community, passing through its history and its collective memories, has the duty to conserve, identify and properly manage its own heritage that, unfortunately, is often susceptible to transformations due to time, ... -
Comparing 3D digitising technologies: where are the differences?
(The Eurographics Association, 2013)We tested five 3D digitization systems and one method of 2D+ recording on one object: a human skull from the Royal Belgian Institute of Natural Sciences collection (RBINS). We chose a skull because it has both simple and ... -
Quick textured mesh generation for massive 3D digitization of museum artifacts
(The Eurographics Association, 2013)The goal of the "3D Icons" European Project, is to provide Europeana with accurate 3D models of Cultural Heritage artifacts. The purpose of this paper is to describe the specific optimized processing pipeline that has been ... -
Anomaly Detection using Remote Sensing for the Archaeological Heritage Registration
(The Eurographics Association, 2013)The aim of this work is an approach using multisensor remote sensing techniques to recognize the potential remains and recreate the original landscape of three archaeological sites. We investigate the spectral characteristics ... -
Measuring Changes in Cultural Heritage Objects with Reflectance Transform Imaging
(The Eurographics Association, 2013)Sites and objects of cultural heritage from art to ancient inscriptions to ruins are under constant attack by time and the environment. While much is known about how material components change from laboratory-based ... -
On-the-fly automatic alignment and global registration of free path collected 3D scans
(The Eurographics Association, 2013)We present a complete geometry processing pipeline for multiple 3D scans alignment, composed by a fast, automated feature-based coarse alignment and an efficient global registration, with the aim to enable high-quality and ... -
A Low-Cost Portable 3D Laser Scanning System with Aptness from Acquisition to Visualization
(The Eurographics Association, 2013)This paper presents the design perspectives of a low-cost portable 3D laser scanning mechanism. The hardware is simple in design, easy to fabricate, and costs much less compared to the cheapest ones available in the market. ... -
3D Reconstruction of an outdoor archaeological site through a multi-view stereo technique
(The Eurographics Association, 2013)This paper describes the experimentation of a common multi-view stereo technique on a particularly complex test case: the ''Via Colonnata'' in the archaeological site of Kyme Eolica in Turkey. The study demonstrates that ... -
Multi-scalar 3D digitization of Cultural Heritage using a low-cost integrated approach
(The Eurographics Association, 2013)In the architectural survey field, one of the main aspects to consider during a 3D digitization is the multi-scalar geometrical complexity of the artifact to acquire, besides other fundamental factors connected with the ... -
Replicating perishable artefacts. A project for analysis and exhibition of Early Medieval objects from the Byzantine village at Scorpo (Supersano, Italy)
(The Eurographics Association, 2013)Artefacts found in an archaeological excavation are sometimes made of perishable or fragile material like wood, iron, or leather. These present obvious conservation problems. This is the case of various artefacts from the ... -
3D documentation of Cultural Heritage artefacts: from data acquisition to virtual conservation and restoration
(The Eurographics Association, 2013)This paper focuses on the development of a procedure for 3D documentation of Cultural Heritage assets and describes all the steps from the 3D data acquisition of the real object, the post processing the raw data and finally ... -
Design and implement a reality-based 3D digitisation and modelling project
(The Eurographics Association, 2013)3D digitisation denotes the process of describing parts of our physical world through finite measurements and representations that can be processed and visualised with a compute r system. Reality-based 3D digiti sation is ... -
Realistic Virtual Reproductions. Image-based modelling of geometry and appearance
(The Eurographics Association, 2013)Existing technologies for contact-less 3D scanning and Image Based Modelling (IBM) methods are being extensively used nowadays to digitize cultural heritage elements. With a convenient degree of automation these methods ... -
Cutting-edge technologies for the survey and documentation of cultural heritage: the case study of the architectural-archaeological area of Aruch in Armenia
(The Eurographics Association, 2013)One of the most important finalities of survey is the architecture's comprehension. To the end of cultural heritage conservation, it is furthermore necessary to communicate the acquired knowledge. In the recent years, this ... -
Monitoring and conservation of archaeological wooden elements from ship wrecks using 3D digital imaging
(The Eurographics Association, 2013)In marine archaeology, many artifacts made of metallic or organic material are found in different state of conservation depending of the environment in which they are discovered. Once brought to the surface for study or ... -
3D documentation and monitoring of the experimental cleaning operations in the underwater archaeological site of Baia (Italy)
