The current predicament of intangible cultural heritage is its vulnerability and rarity, and an expression that is difficult to construct in the space-time dimension. It is difficult for visitors to really understand and touch these local intangible cultural heritages. For this reason, the need to develop new methodologies for cultural heritage learning and art appreciation is always present, and this is increasingly supported by digital technologies. The research in this paper is to apply the self-issuance method to the folk intangible cultural heritage center. It is different from the traditional AR method of presenting crafts directly through HMD. Instead, the use of low-cost technology, Augmented Reality technology and unity 3D technology provide a new way of interaction. By using HMD, smartphone, Leap motion and software created in UNITY 3D, the application of the augmented reality program is achieved. It allows users to interact with the intangible cultural heritage easily and fully it in a virtual physical environment. Based on the principle of human natural interaction, it can be achieved by structured light target image scanning and the design and experiment of photographic measurement. Then a local intangible cultural heritage model database can be established to provide virtual prototype files. The results of the experimental show that the data transmission is effective and the three-dimensional interaction between people and exhibits can be realized. The research results can be applied to the interactive mode practice of the intangible cultural heritage center, and provide an effective interactive mode for the intangible cultural heritage in the form of augmented reality interaction. In this way, visitors can have a deep impression on the intangible cultural heritage and the culture can be spreaded widely all over the world.
