“…Research on mural cultural relic resources mainly focuses on the traditional “humanistic” perspective, deconstructing them from various aspects, such as archaeological periods, rank systems, formal styles and material culture (Jin and Wei, 1975; Li, 1972; Shi, 2016; Su, 1982). In recent years, more scholars have begun to study how to use computer technology and physical or chemical materials to restore tomb murals (Kaew-on et al , 2020; Liu et al , 2022; Rakhimol and Maheswari, 2022; Tortora et al , 2016). From a “digital” perspective, in China, the construction and research of mural cultural relic resources mainly revolve around the “Digital Dunhuang” project (Zhou et al , 2022), including the digitalization of the Dunhuang grottoes (Wang and Zhang, 2022), the “Digital Dunhuang” digital asset management system (Yu et al , 2020) and resource repository (Gong et al , 2022; Wang et al , 2014, 2018, 2020).…”
