Using new design concepts and design methods to effectively strengthen the digital protection of traditional non-heritage culture is an important measure to promote the development of conventional non-heritage culture. In this paper, the digital protection needs of traditional non-heritage culture are sorted out, including the purpose of digital protection of non-heritage, the design level, and the feasibility of the application of virtual reality technology in the digital protection of non-heritage culture. A platform for the digital protection of non-heritage culture is constructed with the model of PHP technology + MySQL database + Apache server combined with virtual reality technology, and the immersion experience and display dissemination model is designed in this platform. In order to obtain accurate digital images of traditional non-heritage culture, this paper utilizes 3D laser point cloud acquisition technology to reconstruct non-heritage culture in 3D. It combines the ICP algorithm to enhance the point cloud alignment accuracy of digital images of non-heritage culture. Evaluation of the effectiveness of the traditional non-heritage culture digital protection platform proposed in this paper was done through performance tests and application practice. The results show that the number of concurrent users of the platform in this paper can reach the maximum throughput of about 94,300 per second in 2000, the point cloud alignment accuracy of the ICP algorithm has an error of only 0.304mm, and the SUS usability evaluation of the platform scores 80.4 points. The construction of a digital protection platform for non-heritage culture using virtual reality technology can provide users with immersive experience scenes.
