Advanced 3D Mapping and Diagnostic Technologies for Constructions and Built Heritage

Dear Colleagues,

The digitization processes in cultural heritage carries multiple meanings, especially within the framework of

interdisciplinar activities and research.

The in-depth knowledge of architectural heritage is currently a relevant need in the framework of heritage conservation plans which typically make use of a complex set of investigations that need to be connected for boosting the complete interpretation of built heritage, in a common purpose of protection and safeguarding, also related to the present challenges regarding new rules of construction facing seismic vulnerability and many environmental- and human-based hazards.

Recently, the 3D survey technologies based on image- and range-based methods, together with the information management strategies in smart systems (digital twins), are called to establish alliances with diagnostic methods for assessing the health of the structures and architectural heritage, so that the comparison and holistic exchange approaches and assessments can guarantee an effective response for a complete and rich vision of the spatial, temporal, multi-content, and multi-scale implications that the complexity and granularity of the architectural heritage imposes.

Adopting these approaches, conservation and enhancement projects are able to guarantee that heritage and its historical and social implications are an engine of cultural development of society, as prefigured by the international agendas and guide lines.

This Special Issue would invite colleagues to submit papers discussing their research activities on recent progress and applications of advanced digitization for heritage structures modeling and monitoring.

The contributions can be related, but not limited to:

• New technologies for 3D mapping, image-range data, visible-non visible heritage and phenomena, aerial-terrestrial sensors, low-cost and portability issues, management of 3D-enriched poin clouds, optimization, segmentation, annotation, AI for point clouds;
• As-built modeling for complex surfaces in the process of structural elements reconstruction, oriented to structural simulation based on multiple construction techniques, with a particular attention to XX century legacies. Masonry, concrete, sperimental and new construction systems and techniques;
• Sensors integration and fusion applied to the digitization of complex heritge structures oriented to documentation and conservation plans;
• Semantic appied to heritage, ontologies, integration of information related to 3D-geometry and structural analysis;
• Structural health monitoring;
• Multi-sensors DT and NDT ispections and integration on heritage structures based on digital models as a multi-dimension database: georadar, termographs, endoscopies, coring, sclerometer index; Ultrasonic tests; corrosion potential, temperature and humidity monitoring; carbonation depth index; elastic modulus and compression tests on the extraction of structure samples;
• Digital twin models as a 3D, intelligent archive for information collection and management of multiples analysis for boosting heritge knowledge and preservation;
• Optimal sensors placement for structural health monitoring;
• Integration of digitization processes for structutal evaluations of existing structures and infrastructures;
• Digital image correlation for damage detection and material degradation phenomena.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
