Automatic 3D acquisition devices (often called scanners) allow to build highly accurate models of real objects in a cost- and time-effective manner. We have experimented this technology particular application context: the Cultural Heritage artefacts. Specific needs domain are: medium-high accuracy, easy use, affordable cost scanning device, self-registered shape color data, finally operational safety for both operator scanned According these requirements, we designed low-cost scanner based...
Post-processing of 3D scanned data is still the bottleneck for a wider diffusion this technology. In paper we describe our second generation tools processing data. particular, support: range maps alignment, merge (or fusion), mesh simplification and color attribute management. This software package has been implemented by scratch encompasses both up-to-date solutions some original methods (merging, simplification, management and, in part, alignment). The presents architecture tools, features...
The program of scientific investigations planned in the framework restoration Michelangelo's David produced several useful guidelines for defining and developing innovative ways to process visualize 3D data cultural heritage applications. Our ultimate goal was include graphics among tools which can help restorers select proper procedures task at hand objectively assess results. For this, an ideal test bed demonstrate usefulness digital models visualization a project. Because complex set...
Abstract Scientific investigations of artworks are crucial in terms preservation since they provide a measurable evaluation the materials and state conservation. This is case Antonello da Messina’s painting “Ecce Homo”: its delicate conservation, with need for constant monitoring, required broad in-depth diagnostic campaign to support restorers. The project was carried out entirely situ using non-invasive cutting-edge techniques proposes multimodal data-centric approach, integrating 3D 2D...
The paper presents a simple and efficient algorithm for the removal of small topological inconsistencies high frequency details from surface models. method, called marching intersections (MI), adopts volumetric approach acts as resampling filter. All intersection points between input model lines user selected 3D reference grid are located then, beginning these intersections, an output is reconstructed. MI, which good characteristics in terms efficiency, compactness, quality models, can be...
The results of a project aimed to the study, reconstruction and presentation public monument disassembled dispersed, mausoleum emperor Arrigo VII, are presented here. We used modern 3D graphics for acquisition accurate digital models all elements funerary complex, draw hypothesis on its original architecture, finally present this knowledge museum public. Issues emerged during scanning discussed. multimedia was implemented with an interactive visualization system, which extended manage...
In this paper, we propose VirtualTour. This is a virtual reality app for Apple iOS 8 (tablets, smartphones) supporting the easy and natural exploration of Cultural Heritage sites captured with 3D scanning technologies or modeled by artists. VirtualTour proposes novel approach exploring exploiting modern mobile devices (tablets phones) their embedded sensors. The navigation constrained to follow pre-defined path in space; user can progress on either manipulating simple slider directly walking...
This paper discusses a case study on the use of augmented reality (AR) within context cultural heritage. We implemented an iOS app for markerless AR that will be exhibited at MUST museum in Lecce, Italy. The shows rich 3D reconstruction Roman amphitheater, which is nowadays only partially visible. state-of-the-art algorithms computer graphics and vision allows viewing exploration ancient theater real-time.
Modern 3D scanning technologies allow to reconstruct digital representations of Cultural Heritage artifacts in a semi-automatic way, characterized by very high accuracy and wealth details. The availability an accurate representation opens several possibilities utilization experts (restorers, archivists, museum curators), or ordinary people (students, visitors). scanned data are commonly used for the production animations, interactive visualizations, virtual reality applications. A much more...
Graffiti is a special form of art which gives us important knowledge on culture and social life lost civilization. Unfortunately, they are usually engraved soft non durable materials. The project described here originated from the request for new approach to preservation, study ubiquitous access Pompei's graffiti. A multidisciplinary team was setup design methodology support digital acquisition, presentation public this peculiar type Cultural Heritage. We have investigated use 3D scanning...
In this work, we will present the outcomes of 3D diagnostic investigations carried out on painting Alchemy by Jackson Pollock. Thanks to an accurate digitization and a careful processing, were able generate very precise high-resolution model that proved be useful in different stages conservation campaign. The was integrated process, along with other investigations; geometric data also used produce images video sequences for dissemination purposes. most interesting aspect however, idea going...
We present a methodology, based on 3D scanned digital models, for measurement and monitoring wood deformations, caused by weather changes, in the trees of fossilized Dunarobba forest. The forest, located central part Italy, was discovered recently after some excavations to dig clay bricks manufacturing. removal mass exposed conditions, initiating process degradation. Different conservation methodologies have been proposed choice best fitting one has be validated means an objective measurable...
Abstract This study aims to demonstrate the potential of 3D analysis in prehistoric ceramic complexes. Due production systems used, pottery decorations can vary significantly. Examining frequency various decorative methods used at different sites may help identify areas potentially connected specific traditional elements. However, this is usually a cumbersome and time-consuming task. digital methodologies bring several advantages interpretation decoration, providing new tools that improve...
Refurbishing Michelangelo's David has produced several useful restoration guidelines. These guidelines can help restorers select the proper procedures for task and, objectively, assess results. The work also helped us develop innovative ways to process and visualize 3D data in cultural heritage projects. was an ideal test bed. We try various methodologies support scientists with visualization tools based on digital models. models be a tool undertaking specific investigations, or as...
The quantitative morphological analysis of a painting surface allows to evidence form defects and study, thus, their influence on the stability paint preparatory layers, as well support. Therefore three-dimensional survey can be very useful in planning restoration intervention painting. In this work we present results carried out "Ultima Cena" by Giorgio Vasari. This panel is severely affected film wrinkling produced consequence flood that occurred Florence 1966. Our analysis, accomplished...
Surface topography is very important for many applications. Today the most used techniques on artworks and stone artifacts require long acquisition times invasive interventions. For this reason, here a non-contact device improved in portability described. It can acquire wide areas short times, so it suitable reconstruction with spatial resolution of some tens micrometers. The starting point commercial conoscopic probe, Optimet Conoline, that able to reconstruct depth profile surface line...
