In April this year, the "Smart Yingxian Wooden Pagoda" plan jointly developed by Lenovo Group and Tsinghua University School of Architecture was released. This is an extended reality application developed based on artificial intelligence and spatial computing technology. By constructing a "wooden tower twin" in the digital world, the complete structure and details of the wooden tower are restored layer by layer, and the history of the wooden tower is condensed into it, allowing the Yingxian wooden tower to be replicated in the digital world. As the oldest and tallest wooden tower style building in the world, Yingxian Wooden Pagoda stands for nearly a thousand years without collapsing due to its unique design, structure, and construction, becoming a world-renowned cultural heritage of Chinese ancient architecture. Meanwhile, due to the gradual accumulation of damage caused by historical factors such as earthquakes, weather, and wars, the task of protecting the Yingxian Wooden Pagoda is becoming increasingly urgent. Starting from February 2023, Lenovo Group and the School of Architecture at Tsinghua University launched the "Smart Yingxian Wooden Pagoda" project, empowering the protection of ancient buildings with new generation information technology. The School of Architecture at Tsinghua University has carried out modeling work on the internal wooden structure of wooden towers and created a wooden tower parameter database through structural parameter research. At the same time, they will transform their research findings into display and popular science content for wooden towers, creating scripts for virtual experiences. Lenovo Group combines artificial intelligence, neural radiation fields, and augmented reality technology to provide technical support for restoring the complete structure and details of the wooden tower. Lenovo Group Vice President Mao Shijie said that during the project development process, the research team has cumulatively utilized over 15 million basic materials, completed nearly 60000 lines of programming, and manually rendered models up to 4.2G. Mao Shijie introduced: "In the first stage, we use drone devices and 360 degree cameras for panoramic scanning and shooting around the wooden tower, completing the collection of thousands of image data inside and outside the tower. In the second stage, we use artificial intelligence technology to analyze and process basic material data, and train deep learning and neural networks to intelligently perceive and understand three-dimensional spatial information, constructing a highly simulated three-dimensional scene. In the third stage, we use augmented reality technology to seamlessly connect the generated three-dimensional model with the real or virtual world. Through the integration and reconstruction of fragmented information, we achieve flexible application and interaction of the three-dimensional model in different scenes. Finally, the" Smart Yingxian Wooden Pagoda "experience application restores the replica of the wooden tower." Five exploration scenes from the first to fifth floors of the tower, achieving simulated tower climbing Breakthroughs in artistic restoration, integration of past and present. In the scenic area where tower climbing has been suspended, tourists can simulate tower climbing through virtual reality devices to learn about the history of Yingxian Wooden Pagoda. In addition, the "Smart Yingxian Wooden Pagoda" project has also established a visual digital information archive to provide support for future wooden tower protection work. In the future, technologies such as artificial intelligence and augmented reality are expected to be applied to on-site surveys of ancient buildings. Liu Chang, Director of the Institute of Architectural History and Cultural Relics Protection at the School of Architecture, Tsinghua University, has long been committed to the protection of Yingxian Wooden Pagoda. He said, "The protection of Yingxian Wooden Pagoda is a systematic project. It is not only necessary to see the appearance, but also to see the internal 'bones', and even the distribution of internal' nerves' and 'muscles'. The collection and application of a large amount of data can not only build generative artificial intelligence applications, but also build bridges between different data." "For ancient architecture, it involves structural protection, material protection, as well as the protection of cultural information such as colored sculptures and murals. Various technologies such as surveying, exploration, structural reinforcement, and material reinforcement need to be used." Wang Xiaolong, Vice President of Shanxi Academy of Ancient Architecture and Colored Sculpture and mural Protection, believes that technological means should serve the protection of cultural heritage. In the future, he hopes to extract more refined surveying and mapping technologies to extract cultural information. "More unknown information about the Yingxian Wooden Pagoda, including its original design, changes at different stages The decay of wood provides stronger support for subsequent protection.
