Digital Protection and Innovation of Intangible Cultural Heritage Skills

Aiming at the problems of non-genetic fault and tacit knowledge loss, this study combines knowledge graph, computer vision and immersive media technology to construct a digital protection framework for intangible heritage. The framework transforms implicit experience into a structured digital model through multi-modal data acquisition; At the same time, a "virtual master" system was built to realize the interactive teaching of skills; In addition, the Virtual Reality (VR) scene restoration and live broadcast linkage strategy is adopted to promote the integration of protection and communication. The empirical results show that the efficiency of VR knowledge transfer reached 91.2%; The results show that the framework can effectively support the activation of intangible cultural heritage (ICH); Industrial-grade Artificial Intelligence (AI) technology can accurately decode and reproduce empirical craftsmanship.
