“…Structure-from-Motion photogrammetry and dense image matching have in fact automated image-based 3D modeling techniques, making photogrammetry a versatile and cost-effective solution for the 3D documentation of existing buildings. Incremental and interoperative processes exploiting multimodal acquisitions are currently under exploration [16,30].…”

This work presents a semi-automatic approach to the 3D reconstruction of Heritage-Building Information Models from point clouds based on machine learning techniques. The use of digital information systems leveraging on three-dimensional (3D) representations in architectural heritage documentation and analysis is ever increasing. For the creation of such repositories, reality-based surveying techniques, such as photogrammetry and laser scanning, allow the fast collection of reliable digital replicas of the study objects in the form of point clouds. Besides, their output is raw and unstructured, and the transition to intelligible and semantic 3D representations is still a scarcely automated and time-consuming process requiring considerable human intervention. More refined methods for 3D data interpretation of heritage point clouds are therefore sought after. In tackling these issues, the proposed approach relies on (i) the application of machine learning techniques to semantically label 3D heritage data by identification of relevant geometric, radiometric and intensity features, and (ii) the use of the annotated data to streamline the construction of Heritage-Building Information Modeling (H-BIM) systems, where purely geometric information derived from surveying is associated with semantic descriptors on heritage documentation and management. The “Grand-Ducal Cloister” dataset, related to the emblematic case study of the Pisa Charterhouse, is discussed.

“…In the past 20 years, de Luca has been involved in several proposals for documenting architectural heritage with 3D models and multimedia documents and navigating this content (Busayarat, De Luca, Veron, and Florenzano, 2010; De Luca, 2014; De Luca, Busayarat, Stefani, Véron, and Florenzano, 2011; Pamart, Morlet, and de Luca, 2019).

“…First, methods for acquisition, 3D reconstruction and structuring according to a thematic model based on morphological criteria were proposed. These were followed by a method to correlate graphic multimedia documents and the 3D model to achieve a projective relation (Busayarat, 2010; Busayarat et al., 2010; De Luca et al., 2011; Pamart et al., 2019). These propositions also introduced the possibility of annotating images or the 3D model (e.g.…”

Many geographic features such as 3D city models, real‐time sensor data and multimedia documents (photo, audio, video, etc.) are nowadays available for describing urban areas. These heterogeneous geographic features are multidimensional (spatial, thematic and temporal), can have multiple representations (text, iconography, etc.) and can be modeled using diverse formats. Browsing and crossing these features can help us to analyze and understand the past and present and plan the future evolution of cities. Furthermore, doing so in a web context allows us to share and enrich them in a collective way. In this article we propose a new generic model (GenLinkable) for integrating such features. We also propose the Gen4DCity‐Doc model which specifies GenLinkable to integrate multimedia documents and time‐evolving 3D city models for web visualization and navigation. Gen4DCity‐Doc extends previous research results by integrating new resources describing cities (multimedia documents). Gen4DCity‐Doc is implemented in a web prototype based on a four‐tier architecture using and enhancing open source software and standards. Finally, we also demonstrate that these models open up new navigation possibilities in 3D city models and in multimedia documents through a 3D web interface, which is a current challenge, especially to help researchers in urban history.

“…In this context, it is worth it to mention the AIOLI reality-based 3D annotation platform. This cloud-based platform allows users, related to the worldwide Cultural Heritage community, to build semantically enriched 3D descriptions of cultural heritage through photogrammetric models and 3D annotations linked with additional resources (Pamart et al, 2019). Due to the global pandemic, these technologies become useful academic teaching tools in absence of on-site experience (Pollalis et al, 2018).…”

Abstract. Archaeological sites in urban areas are often poorly integrated with the modern urban fabric and appear as “trenches” at a lower level than the road. They become neglected and unvalued places. The study of archaeological ruins in urban centres must involve archaeologists and architects to integrate restoration, enhancement and improvement of physical and visual accessibility projects. New digital technologies can improve these activities thanks to 3D models, “digital replicas” that allow even remote study (especially during a pandemic). The paper presents the case study of a private Roman-imperial bath in Catania. The open-air site is located at a depth of 3 metres above the road level and is not exploited. Our study consisted of historical-bibliographical research, direct and SfM surveys that allowed creating a high-resolution textured 3D model. We have extracted orthophotos and sections for geometric and technical-constructive analyses and recognition of decay from this model. We drew up an archaeological restoration and valorisation design. In addition, we imported the model into the Sketchfab portal. So, we enriched the mesh with information from the analyses employing specific tags about annotations, 2D drawings, historical and technical-scientific information. In this way, the model becomes an interactive document to monitor over time the conservation state, validate the restoration design and contribute to the valorisation of the site. This is an easy tool of exchange between all involved users (researchers, professions and students). Thus, the digital replica also represents a very high potential for dissemination purposes.
