Taking clay sculpture non-heritage protection as an example, the main functional modules of the system cloud and mobile terminal are designed. Based on a combination of 3D scanning and iterative mesh simplification, a fast modeling method is proposed. ORB-FV and optical flow tracking algorithm are used for online recognition and tracking registration of images. The system is developed based on Unity3D. The test results show that, the system not only improves the realism and fluency non-heritage products on the mobile end display, but also implements the real-time interactive coloring and displaying function after enhanced display of the model, which enhances the fun and interaction of intangible heritage protection and dissemination.  a1004731X (ISSN)
