Preserving cultural heritage and tourism promoting city values: Applying digitalization trends to cultural heritage

Abstract

Even if the implementation of Heritage Building Information Modeling (HBIM) for historic buildings is still beset with challenges and difficulties, researchers all over the globe are continually developing new technologies, which exhibits positive tendencies. However, there hasn't been a lot of study done on HBIM in Vietnam yet. Therefore, in an effort to expand and promote HBIM to a wider community, the purpose of this study is to digitize cultural heritage in Ho Chi Minh City, Vietnam using a heritage information data model integrated enhanced data model that incorporates Virtual Reality (VR) and Augmented Reality (AR) for the virtual tour, as well as historical preservation; as a result, the city's legacy may have a greater value, both in terms of its tangible and intangible aspects. The research is broken down into four main steps: (1) observing the potential application of 3D Laser Scanning in preserving the tangible cultural heritage; (2) implementing scanning work for a case study in Ho Chi Minh city, Vietnam; (3) identifying the workflow for integrations; and (4) assessing the orientation of the research, the Temple of King Hung in Ho Chi Minh City, Vietnam, is chosen for the case study. The research results show the constraints in utilizing the Trimble X7 3D Laser Scanner; the working experience is examined to improve the future workflow for future case studies. The coupling of HBIM with application history environments for building performance analysis, structural analysis, facilities management, augmented reality, virtual reality, and secure design fire protection for historic buildings may be determined to be beneficial. An altered approach involving VR, AR vision algorithms is also presented by promoting digital tourism, making valuable cultural heritage and tourism accessible to people by technology.
