“…They claim to provide new standards in 3D data capture to be usable by all archaeologist, but their method is empirically defined and the integration of knowledge sources is blurry regarding segmentation and semantic injection. Building archaeology is also a field where 3D applications are used mainly for conservations purpose [65][66][67]. In these contributions, the authors highlight two characteristics of archaeological cases: the heterogeneity of data and the difficulty of processing 3D spatial entities from irregular archaeological objects (artefacts, buildings, layers, etc.).…”

Digital investigations of the real world through point clouds and derivatives are changing how curators, cultural heritage researchers and archaeologists work and collaborate. To progressively aggregate expertise and enhance the working proficiency of all professionals, virtual reconstructions demand adapted tools to facilitate knowledge dissemination. However, to achieve this perceptive level, a point cloud must be semantically rich, retaining relevant information for the end user. In this paper, we review the state of the art of point cloud integration within archaeological applications, giving an overview of 3D technologies for heritage, digital exploitation and case studies showing the assimilation status within 3D GIS. Identified issues and new perspectives are addressed through a knowledge-based point cloud processing framework for multi-sensory data, and illustrated on mosaics and quasi-planar objects. A new acquisition, pre-processing, segmentation and ontology-based classification method on hybrid point clouds from both terrestrial laser scanning and dense image matching is proposed to enable reasoning for information extraction. Experiments in detection and semantic enrichment show promising results of 94% correct semantization. Then, we integrate the metadata in an archaeological smart point cloud data structure allowing spatio-semantic queries related to CIDOC-CRM. Finally, a WebGL prototype is presented that leads to efficient communication between actors by proposing optimal 3D data visualizations as a basis on which interaction can grow.

“…The complexity of the structure of CH models and their size can also represent a problem bordering to the big data sector. To date, doesn't exists a global standardized model applicable to all kinds of cultural goods like BIM for new constructions (Scianna et al, 2014), even if in the last few years some authors have been proposed extensions of BIM applicable to CH (Dore and Murphy, 2012). On the basis of what said before, the proposition of simple and more suitable ways to publish on the web 3D models is a relevant aspect; it is necessary to study both the building structure of CH and the most appropriate Web compliant method for sharing geospatial 3D information, in relationship with the specific CH to describe (Fig.…”

ABSTRACT:In the last few years, the need to share on the Web the knowledge of Cultural Heritage (CH) through navigable 3D models has increased. This need requires the availability of Web-based virtual reality systems and 3D WEBGIS. In order to make the information available to all stakeholders, these instruments should be powerful and at the same time very user-friendly. However, research and experiments carried out so far show that a standardized methodology doesn't exist. All this is due both to complexity and dimensions of geometric models to be published, on the one hand, and to excessive costs of hardware and software tools, on the other. In light of this background, the paper describes a methodological approach for creating 3D models of CH, freely exportable on the Web, based on HTML5 and free and open source software. HTML5, supporting the WebGL standard, allows the exploration of 3D spatial models using most used Web browsers like Chrome, Firefox, Safari, Internet Explorer. The methodological workflow here described has been tested for the construction of a multimedia geo-spatial platform developed for three-dimensional exploration and documentation of the ancient theatres of Segesta and of Carthage, and the surrounding landscapes. The experimental application has allowed us to explore the potential and limitations of sharing on the Web of 3D CH models based on WebGL standard. Sharing capabilities could be extended defining suitable geospatial Web-services based on capabilities of HTML5 and WebGL technology.

“…Many researches are focusing their attention on building a system that can be adapted to all CH cases studies, even to the archaeological areas [4]; however, it is still very difficult to find it because each situation is very different from the others, having particular and unique needs and history. For this reason, hard structured information system cannot be actually used in CH field, which requires more dynamic systems, capable of self-adapting to every case for covering all possible needs.…”

BIM and cultural heritage: compatibility tests in an archaeological site

Nowadays, when people speak about BIM software, they refer to new constructions, made by regular elements and standard parameters. The question is: what happens when you, instead of a new building, consider an ancient or existing one? To answer this question, we have evaluated the possibility of using the BIM process effectively for the conservation and proclamation of Cultural Heritage. The target is to test the BIM programs, satisfying the requirements of new buildings, and see if they can also be successfully used in complex situations, like the ones linked to the Cultural Heritage field, where you have to consider the unicity of the architectural elements, the constructive systems and materials (those are not standardized as the new ones), the degradation of the structures and the environmental conditions. In particular, the research examines the case study of the archaeological area of the Sanctuary of Diana in Nemi (Rome), which is an important example in the National Heritage. The final product consists of a parametric model, where you can find, embedded in a database, all the information about the elements and the management of conservation projects. Highlighting positive aspects and existing limits we want to contribute to further studies on the subject, leading to a mandatory implementation and use of this software, even in relation to future European legislative framework.
