Architectural Survey Techniques for Degradation Diagnostics. An Application for the Cultural Heritage

Abstract

Abstract. The great technological development in recent years in the field of architectural survey has made possible increasingly expeditious and less invasive investigations with the aim of acquiring a series of data related to the asset and fundamental for the protection of cultural heritage. In addition, the synergy between the various techniques represents an added value able, not only, to fill possible gaps and lacks arising from application limits of the instruments, but also to enhance the peculiarities of the same. This paper presents an integrated survey activity (range-based, image-based and IR thermography techniques) aimed at applying the combination and collaboration of multiple sensors for the analysis and study of historical buildings as well as for the generation of digital repository to support current and future investigations. In particular, the attention has been on the Chiesa dell’Annunziata located in the municipality of Sessa Aurunca in the province of Caserta (Italy). By carrying out a systematic process of survey, colorimetric-material analysis and thermographic investigations, the work has allowed to identify the main forms of degradation that characterize the structure and the causes that generate it. The work conducted through the combination of multiple technologies demonstrates, once again, the importance of synergy and integrations between several instrumentations useful for the documentation of the built heritage, characterized by complex analyses and investigations based on increasingly interdisciplinary approaches.

An Effective Approach for Point Cloud Denoising in Integrated Surveys

“…The complex articulation of the available solutions suggests that the topic of filtering is central in a vast range of applications. However, our objective is not to conduct a review or to delve into the specificities of the different approaches but rather to propose a robust and easily replicable workflow to produce reality-based models deriving from integrated survey operations (Alonso et al, 2016;Morena et al, 2021;Limongiello et al,2020). The combination of systems and sensors now represents a consolidated practice in the field of surveying and this allows us to respond effectively and efficiently to the critical issues and singularities of specific applications.…”

Studio preliminare sul complesso fortificato di Trogir (Croazia) basato su un approccio multi-disciplinare

“…Nonostante tali lavori, la fortezza si presenta attualmente in uno stato di conservazione piuttosto compromesso: oltre a mostrate numerose criticità a livello strutturale (dissesti fondali), essa mostra anche un quadro di degrado avanzato delle di numerose concrezioni calcaree e patine da biodegrado. In tale scenario l'utilizzo di tecniche non distruttive (Non-Destructive Techniques) e non a contatto (Non-Contact Technique) quali il permettono di ottenere una base di riferimento per una conoscenza integrata storica, architettonica e sperimentale dei beni monumentali (Costanzo et le varie tecniche rappresenta un valore aggiunto in grado non solo di colmare eventuali lacune e carenze derivanti dai limiti applicativi degli strumenti, ma anche di valorizzare le peculiarità degli stessi (Morena et al 2021).…”

Application of Action Camera Video for Fast and Low-Cost Photogrammetric Survey of Cultural Heritage

“…Instrumentation is now much more manoeuvrable, and software ensures sufficient accurate results even with automated processes, making easier the analysis and the management of the data. In the international literature, several studies focus on multi device survey of cultural heritage as a method to produce accurate and precise documentation (Hassani, 2015;Adamopoulos and Rinaudo, 2017;Morena et al, 2021). Along with the development of active and passive sensors, the software tools used for data management have been strongly updated and improved (Kingsland, 2020).…”
