This study proposes an end-to-end replicable digital preservation solution for the Jinshanling Great Wall (Luanping County, Chengde City, Hebei Province), covering the full lifecycle from production to implementation. Rooted in the "technology-culture-education" philosophy, a comprehensive Extended Reality (XR) system was developed by integrating Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) with ancient architectural cultural heritage tourism and preservation. Through multi-round iterative optimization, the system achieved 5mm precision and a model face count exceeding 50,000. Core technological innovations include: a customized Effective Field of View (EFOV) method for VR panoramic stitching, an optimized point cloud precision formula for AR reconstruction, and a Simultaneous Localization and Mapping (SLAM)-based MR framework enabling bidirectional virtual-real interaction. A near-comprehensive heritage database and full-process (site selection-analysis-implementation) XR preservation solution were finalized.
