This paper constructs an immersive virtual inheritance system for the digital inheritance of traditional residential architectural cultural heritage, which integrates real image acquisition, point cloud reconstruction, component level semantic annotation, virtual space organization, interactive behavior perception and cultural content mapping into a unified computing framework to realize the collaborative expression of architectural form, decorative details, structural relationships and regional cultural narrative. Based on 286 traditional residential buildings, 4120 sets of scene interaction samples and 13840 semantic annotation data, the system completes 3D model training, space mapping and interaction testing. The results show that the completeness of 3D reconstruction is 94.8%, the texture fidelity is 93.5%, the accuracy of cultural content mapping is 92.6%, the average interactive response delay of the head-worn terminal is controlled at 76ms, and the task completion rate is 89.7%. The success rate of scene loading is 97.1%, the node hit rate is 91.4%, and the content traceback rate is 86.0%. The system performs stable in space identification, knowledge understanding and process recording. This method can enhance the ability of space identification, knowledge understanding and process recording while maintaining architectural authenticity and cultural coherence, which provides a computable, deployable and scalable implementation path for digital inheritance education of traditional residential architectural cultural heritage in immersive virtual environment.
Povzetek: Ta članek gradi potopitveni virtualni sistem dediščinskega prenosa, ki združuje zajem slik, rekonstrukcijo oblaka točk, semantično označevanje, prostorsko organizacijo in kulturno preslikavo za digitalni prikaz tradicionalne stanovanjske arhitekturne dediščine. Poskusi kažejo, da je sistem dosegel 94,8 % popolnost rekonstrukcije, 92,6 % natančnost preslikave in odzivni čas 76 ms. Sistem izkazuje dobro stopnjo avtentičnosti, interaktivnosti in zmožnosti uvajanja.
