This rare mural, which was looted abroad and later destroyed in war, no longer exists, but researchers have used digital technology to recreate its charm. As the volunteer guide pointed in the direction, the audience turned to the exquisite colored painting on the top of their heads, inspired by the diamond grid composition of the Kizil Grottoes. The "Colorful Versatile - Immersive Experience of Grottoes Art" exhibition at the National Museum of China has been favored by many visitors since its launch. By means of AI algorithm, digital interactive application and other technical means, the exhibition brings together cultural treasures such as Kizil Grottoes, the Mogao Grottoes of Dunhuang, Maijishan Grottoes, Yungang Grottoes and Longmen Grottoes. The commentator explained that the exhibition digitizes and recreates historical relics, opening up a new perspective for analyzing and viewing grotto art, and bringing non renewable and immovable cultural heritage to life. Within an immersive exhibition space of approximately 1500 square meters, the aesthetic pursuit, value concepts, and cultural charm carried by Chinese grotto art are fully demonstrated. The decorative patterns of caisson, pingqi, mural border decoration, etc. in the Mogao Grottoes of Dunhuang, after classification, extraction, superposition and recombination of pattern data, form a dynamic pattern vortex, like a kaleidoscope. The essence of Weibei calligraphy on the inscriptions of the steles and statues in Longmen Grottoes, "Longmen 20 Grades", has been processed by AI algorithm and AR infrared trigger technology, and the audience can generate various fonts such as oracle bone inscriptions, inscriptions on gold, official script, cursive script and running script by "patting" with their hands. In recent years, digital technologies such as AI have injected new vitality into traditional cultural relics exhibitions at home and abroad. They can not only restore scenes of unearthed cultural relics and recreate disappearing ones, but also make incomplete cultural relics complete and faded cultural relics shine again. Digital technology supports the continuous development of immersive and interactive exhibitions, empowering the protection and utilization of cultural relics and the preservation and inheritance of cultural heritage. April 18th is International Day of Monuments and Sites, and the theme of this year's International Day of Monuments and Sites is "The 60th Anniversary of the Venetian Charter and the Challenges of the Times.". According to the relevant provisions of the Venetian Charter, the protection and restoration of historical sites must rely on all scientific and technological advancements that are beneficial for the study and protection of archaeological heritage. At the Phoenix Center in Beijing, a VR immersive exhibition with the theme of exploring the Egyptian pyramids, created by a Sino French team, can receive up to a thousand visitors per day. It is reported that the exhibition uses holographic scanning technology to accurately reconstruct and restore the interior and surrounding environment of the pyramid on a virtual engine. Bending down through the mysterious and dark secret passage, entering the interior of the pyramid, climbing to the top of the pyramid to overlook the Giza Plateau, and boating on the Nile River to experience beautiful scenery... The audience wears VR headsets to get up close to the internal structure and historical context of the pyramid, and explore ancient Egyptian civilization in person. The overall layout plan for the construction of Digital China proposes to create a confident and prosperous digital culture, and promote the digital development of culture. Enhance digital cultural service capabilities, create several comprehensive digital cultural display platforms, and accelerate the development of new cultural enterprises, cultural formats, and cultural consumption models. Professor Fei Jun from the Central Academy of Fine Arts said that nowadays, it is not uncommon to see scenes that integrate digital technology, such as museums and heritage parks. The integration of culture and technology can enable cultural heritage to be passed down in a dynamic way, and establish a cultural and cultural connection
