The paper presents the development of an integrated digital platform for the remote access, documentation, and dissemination of an inaccessible archaeological site. The methodology combines multi-source digital survey techniques—including UAV photogrammetry and terrestrial laser scanning—with 3D modeling and semantic data integration to generate accurate digital replicas of the site. These models are implemented within immersive environments (VR and WebXR), enabling virtual tours, interactive exploration, and data querying through user-friendly interfaces. The platform supports both scientific analysis and public engagement, integrating spatial data, annotations, and multimedia content into a scalable knowledge system. The research highlights the potential of immersive technologies to overcome physical accessibility constraints, while also supporting heritage conservation, monitoring, and valorisation through interoperable digital ecosystems.
Point Cloud Data Semantization for Parametric Scan-to-HBIM Modeling Procedures
This paper proposes a structured methodology for converting survey data into semantically enriched HBIM models through Scan-to-HBIM workflows. The research integrates point cloud acquisition, segmentation, and parametric modeling within a hierarchical data framework aimed at generating reusable and information-rich digital representations of historical architecture.
The workflow combines terrestrial laser scanning, mobile SLAM, and photogrammetry, followed by post-processing and semantic segmentation to isolate architectural components. These elements are then classified and linked to parametric BIM families through a taxonomy-based system, enabling the creation of adaptive Historic Building Object Models (HBOM). The approach supports both geometric accuracy and information management, facilitating interpretation, conservation planning, and model reuse. Results highlight the effectiveness of semantic structuring in improving HBIM processes, while confirming the need for case-specific modeling strategies due to the complexity of built heritage.
