Improving the digitization of shape and color of 3D artworks in a cluttered environment
(The Eurographics Association, 2013)We propose an approach for improving the digitization of shape and color of 3D artworks in a cluttered environment using 3D laser scanning and flash photography. In order to separate clutter from acquired material, ... -
Integrated method for tracking changes in archeo-landscapes using remote and close-range technologies
(The Eurographics Association, 2013)The importance of visible built heritage and archeolandscapes for preservation of collective memory and identity is widely acknowledged across disciplines regarding heritage protection and valorisation. The complex analysis ... -
Low-cost mobile system for multispectral cultural heritage data acquisition
(The Eurographics Association, 2013)In the paper we propose an alternative approach to the multispectral data acquisition of the cultural heritage artifacts. The demonstrated solution is mobile, affordable, and consists only of commercial off-the-shelf ... -
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. ... -
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 ... -
A Methodology for Updating 3D Solid Models of Complex Monumental Structures Based on Local Point-based Meshes
(The Eurographics Association, 2013)Structural changes introduced during the life of monuments contribute to produce complex geometrical configurations that cannot be properly represented in standard solid modeling systems designed for current engineering ... -
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 ... -
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 ... -
Nondestructive Investigation of the Internal Structure of Fresco Paintings
(The Eurographics Association, 2013)New methods to measure the internal structure of wall paintings include single-sided nuclear magnetic resonance (NMR) and terahertz time-domain imaging (THz). We report the measurement of eight fresco models prepared with ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Reverse Engineering of Scale Models Using Dataflow Programming: Application to the fortification of plans-reliefs
(The Eurographics Association, 2013)Despite the progress in three-dimensional scanning, some architectural artifacts remain a digitizing challenge. Scale models and more especially the plans-reliefs of Louis XIV of France have specific characteristics such ... -
Surface Light Field from Video Acquired in Uncontrolled Settings
(The Eurographics Association, 2013)This paper presents an algorithm for the estimation of the Surface Light Field using video sequences acquired moving the camera around the object. Unlike other state of the art methods, it does not require a uniform sampling ... -
Temporal Terrestrial Laser Scanning to Visualize the Archaeological Excavation Process
(The Eurographics Association, 2013)Archaeology is a destructive science. Photographs and videos preserve some aspects of the sequence of events inherent within the archaeological excavation process, but cannot replicate the spatiality and detail of the ... -
Underwater photogrammetry for archaeology and marine biology.40 years of experience in Marseille, France
(The Eurographics Association, 2013)Since 1973 archeology and computer science have developed close ties in Marseille. Two departments (computer science and archaeology) from the French National Centre for Scientific Research (CNRS) in Marseille started ...
