To address this issue, some studies have used the Industry Foundation Classes (IFC) file format which, unfortunately, lacks functionalities for VHE creation, complicating the process for non-IT users. This paper introduces a semi-automated HBIM-to-VR workflow using an enriched IFC file. The process includes a manual phase for preparing the IFC file with metadata and a subsequent automated phase where a VR platform generates a virtual visit.

The safeguarding of such resources may benefit from the advantages DT offer, nevertheless the relation between both subjects could use further exploring. This work consisted in the development of an evaluation methodology named Heritage Digital Twin (HDT), composed by four attributes determined by the relation between DT and built heritage, which also demanded a brief revision of the concepts and primary elements of the DT concept, as well as previous DT evaluation frameworks. Three Portuguese case studies were used to exemplify the application of the methodology at different scales (in size, relevance and DT complexity). The application examples proved the methodology is able to provide an easy and effortless HDT assessment, allowing a simple yet meaningful indication of the development of each attribute. Heritage-related actions are still limited following the virtual-to-physical communication, in contrast with operative actions, which causes HDT to rely on human intercession. The framework successfully considered built heritage limitations, providing an inclusive approach.

The collected data set samples from the internet were complex in nature to read the contents present on stone images. The experimental workflow of the proposed method is to separate the text and non-text regions from the stone inscription images using a proposed technique for setting the coordinates. Then, the preprocessing process starts to filter out the noises and other unwanted regions found in the image foreground region using the median filtering composition method. Finally, the hybrid approach is implemented using a Fuzzy adaptive thresholding technique for the elimination of the background region of the input image and smooth enhancement of Kannada stone inscription images due to enormous challenges related to perspective distortion, diverse lighting conditions, the minimal disparity between the foreground and background, a lack of standardized text size and shape, reduced perceptible colour contrast, and associated noises. Hence, we obtained an enhancement accuracy of 78.18% using a hybrid method. The obtained accuracy is more acceptable compared to existing methods found in the global literature and is also carried out during the experimental study.

The irregular cross-section profiles are extracted using point cloud slicing and the Alpha-Shape algorithm. Geometric characteristics such as cross-section area, moment of inertia, and moment of resistance are calculated using Green's integral method. The performance of this method is evaluated by measuring eight groups of deteriorated components with different cross-section characteristics and comparing it with five traditional methods. The results demonstrate that the proposed method improves the calculation accuracy by 1%–21% relative to traditional methods, thereby enhancing reliability by 9%–54%. Additionally, it reduces manual calculation workload and human error, while promoting calculation efficiency.
