In order to use digital technology to protect intangible cultural heritage and regional culture, the innovative digital design of intangible cultural heritage is put forward from the perspective of Internet. This paper puts forward a collaborative innovative design method of “root carving technology+digitalization”. Taking “Zhu Zhanghuis lecture” in Yuelu Academy as the representative, this paper explores the innovative methods of developing scene-based root carving products by regional culture. The results show that the acceptance of using light-cured resin as the accessory of root carving is not high, and the proportion of people in the industry who appreciate or accept it is only 71.3%. Developing the design around the basic model is conducive to improving production efficiency, ensuring the improvement of efficiency while retaining the uniqueness of hand-made. The whole root carving product has a certain artistic conception, and can appreciate the connection with the concept of time, but the specific story can be strengthened. Conclusion: Integrating the situational story method into the root carving design of Hunan School can enhance the overall atmosphere and story of the root carving works, enhance the story of the root carving cultural and creative products of Yuelu Academy, and be conducive to the promotion and dissemination of regional root carving culture and academy culture.
