Virtual reconstruction design strategy for the Suoyang city site

There is relatively little research on the restoration and display of Silk Road sites; these are typical earthen ruins consisting of wind-eroded sandy land and scattered wall sections, and almost no remains are found on the ground. This study takes the Suoyang city site as an example and uses digital technologies such as drone oblique photography, 3D laser scanning, virtual reality (VR), augmented reality (AR), and artificial intelligence (AI) to construct a 3D digital model of the Suoyang city site. Through onsite research, this paper analyzes the perceived value of the ruins according to visitors, extracts the core elements of restoration design elements, and proposes a digital method for restoring the sites on the basis of value perception enhancement. A multimodal data-driven virtual reconstruction design process is proposed. The research results provide a technical path and theoretical reference for the virtual reconstruction of other city sites around the world.
