In recent years, the protection of intangible cultural heritage (ICH) has garnered significant attention, emerging as a novel approach to cultural transmission. This article explores the integration of digital twins (DT) with the conservation of Huizhou traditional wooden carvings (Hu-TWC). Initially, the article outlines the principles of DT and then, using Hu-TWC as a case study, it examines the application of this technology in the preservation of cultural heritage buildings. The study analyzes the challenges encountered in digital preservation (DP) and the methodologies employed. DT facilitates the support necessary for ICH preservation and this paper provides a detailed analysis of methods to achieve DP within the digital twin framework, including digital reconstruction, geometric structuring, sensor data integration, photographic and imaging techniques and immersive experiences. The protection and inheritance of Hu-TWC are realized through virtual experiences and digital modalities. The findings highlight the potential and limitations of digital twin technology in the protection of cultural heritage, offering insights for future applications.
