The integration of digital art design and science and technology has become the core industry of the knowledge economy in the 21st century. Immersive virtual reality technology is widely used in cultural preservation and inheritance, providing a new way for cultural digital display. This study explores the path of immersive virtual reality technology on the construction of cultural identity in the context of digital art design. By constructing a virtual scene of digital art and culture based on the virtual engine of the cloud platform and the HTC Vive device, we propose the difference loopback detection algorithm based on the historical model and the binocular parallax virtual stereoscopic display method, and study how the virtual reality technology enhances the user’s sense of cultural identity. The experiment conducted a 4×4 mixed design test on 80 college students and found that under the influence of aesthetic rate and contact form, the subjects’ attention level, emotional potency and self-esteem level reached significant differences (P<0.05). The user satisfaction survey showed that the overall satisfaction with the digital art and culture virtual scene amounted to 4.45 points (out of 5), with the highest score (4.46 points) for the cultural learning dimension. The results of the study show that immersive virtual reality technology can effectively enhance the user’s immersive experience of culture and art and improve the sense of cultural identity; the loopback detection algorithm based on the history model and the performance test of SLAM on the cloud platform gained a performance improvement of 49.57%-74.33% compared to the local scheme, which provides technical support for the construction of the digital art and culture virtual scene with strong consistency. This study provides technical and theoretical references for the design of digital art and culture virtual scenes, and promotes the digital protection and inheritance of cultural heritage.
