【摘要】 为了有效地保护和传承建筑遗产，文章提出了建筑遗产保护的数字化防御策略，并探讨了VR技术在建筑遗产保护数字防御策略中的应用。以57窟为例，我们利用扫描和建模技术对其进行了数字化重构，并基于Unity3D平台开发了一个VR应用程序。该程序允许用户通过VR眼镜进入57窟的虚拟场景，观看其原貌，并与墙壁、石像等进行交互、观察，还能近距离查看交互界面的介绍。构建建筑遗产保护数字化防御体系为保护建筑遗产免受人为侵害提供了有力保障，通过数字化技术实现对建筑遗产的全方位保护，为文化传承提供有力支撑。更多还原

【Abstract】 In order to effectively protect and inherit architectural heritage, the paper proposes a digital defense strategy for architectural heritage protection, and explores the application of VR technology in the digital defense strategy of architectural heritage protection. Taking Cave 57 of Dunhuang Mogao Grottoes as an example, the cave was digitally recorded by using three-dimensional laser scanning and photogrammetry technology, and a VR application was developed based on the Unity3D platform, which allows users to enter the virtual scene of Cave 57 through VR glasses, and watch the original appearance of Cave 57 in the scene, interact with the walls and statues to observe them closely and introduce them in the interaction interface. Constructing a digital defense system for architectural heritage protection can protect architectural heritage from human infringement effectively, and realize the digital protection of architectural heritage, which is conducive to cultural inheritance.更多还原
