Research on Digital Protection and Inheritance Strategy of Non-Heritage Culture Based on Artificial Intelligence

In order to solve the current problems of single form and poor interactivity of intangible cultural heritage protection, research on digital protection and inheritance strategies of intangible cultural heritage based on artificial intelligence is proposed. Taking the protection of clay sculpture intangible cultural heritage as an example, this paper designs the main functional modules of the system cloud and mobile terminals, proposes a rapid modeling method based on a combination of three-dimensional scanning and grid iterative simplification, and uses ORB-FV and optical flow tracking algorithms to achieve online recognition of images. and tracking registration, complete system development based on Unity3D, and conduct experimental verification. The experimental results show that the total time taken by the system to complete image recognition, tracking registration and three-dimensional rendering is 36.5ms, which can meet the real-time system requirements of mobile augmented reality. Conclusion: This system not only meets the requirements of realism and fluency for the enhanced display of intangible cultural heritage products on the mobile terminal, but also realizes the real-time interactive coloring display function after the enhanced display of the model, which enhances the fun and interactivity of the protection and dissemination of intangible cultural heritage.
