文化遗产的数字化保护与传承是当前文化可持续发展的重要路径。以福州“上下杭”历史文化街区为研究对象,探讨基于VR智能交互技术的数字化保护与传承方法。通过构建“上下杭”文化街区的三维虚拟场景,结合Unity引擎与AI技术,设计并实现了一套具备虚拟漫游、智能对话与文化传播功能的沉浸式体验系统。该系统不仅提升了用户体验的沉浸感和互动性,还通过智能NPC的交互与知识获取机制,增强了文化知识的传播效能。本研究为文化遗产的数字化保护与创新传承提供了技术实现路径与理论参考,具有一定的实践与推广价值。

The digital protection and inheritance of cultural heritage is an important path for sustainable cultural development. This paper takes Fuzhou's "Shangxiahang" historical and cultural block as the research object and explores methods for digital protection and inheritance based on VR intelligent interaction technology. By constructing a 3D virtual scene of the "Shangxiahang" cultural block and combining the Unity engine with AI technology, an immersive experience system with virtual roaming, intelligent dialogue, and cultural dissemination functions is designed and implemented. The system not only enhances the immersion and interactivity of user experience but also improves the effectiveness of cultural knowledge transmission through intelligent NPC interaction and knowledge acquisition mechanisms. This study provides a technical implementation path and theoretical reference for the digital protection and innovative inheritance of cultural heritage, with certain practical and promotional value.
