Characterization of European Lacquers by terahertz (THz) reflectometric imaging
(The Eurographics Association, 2013)
In this study a European lacquerware replica has been investigated by terahertz (THz) reflectometric imaging. The inspected lacquerware is a wooden panel covered by multiple complex layers of lacquers and plaster. Utilizing ...
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 ...
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 ...
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 ...
Dense Image Matching: comparisons and analyses
(The Eurographics Association, 2013)
The paper presents a critical review and analysis of dense image matching algorithms. The analyzed algorithms stay in the commercial as well open-source domains. The employed datasets include scenes pictured in terrestrial ...
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 ...
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 ...
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 ...
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 ...
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 ...
