3d Models and Non-Destructive Investigations: Towards a Meeting in Digital Twins

Abstract

Abstract. The digitisation projects of architectural heritage are a field of research continuously evolving and updating in parallel to technological innovations that allow to progressively boost the challenges and requirements of geometric and semantic richness of the related digital configuration of results. Among the arduous tasks under observation, there is the increasing need to harmonize and make the spatial and heterogenous information aspects cooperating. This paper focuses on the procedures for structuring an information system based on the as-built modelling strategy applied on a particularly relevant example of reinforced concrete architecture, which presents the bearing structure of the structural elements featured by complex geometries and roofing conceived as ferrocement wavy elements and therefore equally unusual as a construction system. The entire project refers to a conservation plan that involves structural non-destructive investigations that inquiry the state of health of the structures and their seismic performance. The purpose is to structure a parametric system, based on HBIM technology, which enables the archiving of investigations and results in order to strengthen direct spatial reference between geometric elements and structural analysis results, based also on image and range-based surface analyses, in the direction of a digital twin of the architectural complex.

3D Data Fusion for Historical Analyses of Heritage Buildings Using Thermal Images: The Palacio de Colomina as a Case Study

“…In fact, this increasingly popular technology has demonstrated that the informative models derived from reality-based data-such as point clouds, 3D mesh, orthophotos and archival sourcesnot only need to be used as standalone data, they can be merged in an HBIM to provide a powerful tool for heritage experts. Such an information system allows the management of multi-disciplinary analyses of the considered buildings [40][41][42].…”

Integrated 3D Mapping and Diagnosis for the Structural Assessment of Architectural Heritage: Morano’s Parabolic Arch

“…If it is ascertained that many aspects of the reality-based techniques that we now consider traditional are largely established, and since the automation imprinted by the SfM (structure from motion) techniques [ 13 , 14 ] have allowed for the photogrammetric techniques to be able to supply point clouds substantially similar to the LiDAR (light detection and ranging) ones, attention can now be moved to the innovation of processing processes, which often include optimizing hybrid systems and allowing for obtaining multi-sensor and multi-content surface models [ 15 , 16 ].…”

Rediscovering Cultural Heritage Sites by Interactive 3d Exploration: A Practical Review of Open-Source Webgl Tools

“…Sharing digital twins of monuments or CH sites with a wider audience opens several opportunities in different areas, ranging from geomatics to urban planning, but also to tourism and architecture. Indeed, the accessible accurate 3D model of an ancient building with data in the form of pointclouds and 3D triangulated meshes provides essential information for studying adequate restoration measures, making it possible to adopt Building Information Modelling (BIM) standards (Dursun et al 2022, Patrucco et al, 2022. Moreover, this data can be further enriched through the application of state-of-the-art machine and deep learning algorithms that allow for first identifying critical structural components and then evaluate the need of targeted interventions , Matrone et al, 2020.…”
