An Integrated 3D Geodatabase for Palladio's Work

The paper presents a novel digital 3D GIS web-based system entirely founded on Google Earth, built to offer a deep insight into Palladios opera for restitution of its architectural surveys, reconstruction for historical reasons, analysis for structural and other options, and assembly and presentation of all certified Palladian documentation. The development of the application follows the philosophy of visual computing and it is based on an architectural knowledge representation. The information system is conceived as a typical Rich Internet Application and it is based on the digitalization of the complete Palladian corpus documentation implemented by the Centro Internazionale di Studi di Architettura Andrea Palladio (CISAAP). The 3D geodatabase system is, actually, in use at the Centro as the Palladian information system for researchers and in two expositions at Barbaran da Porto Palace in Vicenza, and at Villa Poiana at Poiana Maggiore, where is widely used by tourists for virtual visits to Palladian buildings.

Bologna Porticoes Project: 3D Reality-Based Models for the Management of a Wide-Spread Architectural Heritage Site

Among the actions developed in order to submit the Bologna porticoes ensemble to World heritage sites of UNESCO, there is a platform conceived for on-line accessing the huge amount of data and resources related to the porticoes. The core of platform will consist of reality-based high quality 3D models usable and navigable within the system as main user interface. The paper describes methods, procedures and best practices developed to implement the digital archive with checked uniform quality and consistency reality-based 3D digital models.

Securing Color Fidelity in 3D Architectural Heritage Scenarios

Ensuring color fidelity in image-based 3D modeling of heritage scenarios is nowadays still an open research matter. Image colors are important during the data processing as they affect algorithm outcomes, therefore their correct treatment, reduction and enhancement is fundamental. In this contribution, we present an automated solution developed to improve the radiometric quality of an image datasets and the performances of two main steps of the photogrammetric pipeline (camera orientation and dense image matching). The suggested solution aims to achieve a robust automatic color balance and exposure equalization, stability of the RGB-to-gray image conversion and faithful color appearance of a digitized artifact. The innovative aspects of the article are: complete automation, better color target detection, a MATLAB implementation of the ACR scripts created by Fraser and the use of a specific weighted polynomial regression. A series of tests are presented to demonstrate the efficiency of the developed methodology and to evaluate color accuracy (‘color characterization’).

SACHER: Smart Architecture for Cultural Heritage in Emilia Romagna

The current Cultural Heritage management system lacks of ICT platforms for the management and integration of heterogeneous and fragmented data sources and interconnection between private and public subjects involved in the process. The SACHER project intends to fill this gap, working both on a technological level and on a business model level: firstly providing a platform based on an open-source distributed cloud-computing environment for the management of the complete data lifecycle related to cultural assets; moreover providing new models based on participatory design for Cultural Heritage data directed towards social entrepreneurship. This paper presents the first implementation of a system for managing data based on the 3D model of the cultural object, with a focus on the process for cultural assets management and the interface design for cultural services.

A Framework for a Smart Cultural City

The paper, aiming to retrieve the original meaning of Smart City, attempts to demonstrate its impact in the field of Cultural Heritage (CH). It presents a framework - applied in a project for a prototypical case study of ‘Widespread Built Heritage’ (WBH) - to create a Smart cultural city, transforming Cultural Items into Smart Cultural Objects (SCO), meant as sources and recipients of advanced information. The framework aims to provide an extensive and robust theoretical support to design and to manage the processes of Cultural Objects (CO) and Cultural bins, implementing a methodological system and an advanced environment based on Smart technologies.

The Production of 3D Digital Archives and the Methodologies for Digitally Supporting Research in Architectural and Urban Cultural Heritage

The paper presents a critical analysis regarding the methodological approach useful to produce 3D digital contents of Cultural Heritage artifacts in context of Digital Archives. The structure of 3D model and the reconstruction process are analyzed in order to elaborate and formalize semantic knowledge concerning the work of art, object of study. Some experiences recently carried-out can show the development of some web-based platform able to allow the use of contents properly related to the characteristics of the case study.

Photogrammetry and Multispectral Imaging for Conservation Documentation – Tools for Heritage Specialists

Information and communication technology applications and the preservation, research and popularisation of heritage have attained an important position in the conservation, heritage management and art studies of cultural heritage. As cultural heritage has a lot of different aspects and there is often a need of continuous scientific research and preservation to gather valuable information from our history and provide better understanding for future generations. Although there have been numerous projects around the world, over the past four years become combination of several technical analysis very important cultural heritage documentation solution in Estonia. Supporting that development is the wider knowledge and better accessibility of the instrumental studies, imaging and survey technologies. Combination of non-destructive and destructive surveys provides enriched information about heritage artefacts that may considerably help conservation and heritage specialists especially when it is accessible over the Web. In these following cases study of research connected with art, we tested and used different imaging and information technologies and the possibilities that may in the future be applied in the landscape of museums and cultural heritage protection for improved documentation of Estonia’s heritage.
