Sanxingdui, which "sleeps for three thousand years, wakes up and shocks the world" is new again!
This time, it still did not disappoint: the tortoise-shaped grid that resembles a "barbecue grill", the bronze statue of the top snake with complex craftsmanship... Each piece of national treasure is amazing.
Sanxingdui is worthy of being the "top class" in the cultural and excavation industry. Its strange, cute and lovely style makes people fascinated by it. I want to "travel" back to the mysterious ancient Shu Kingdom to find out, and I want to go deep into the archaeological excavation site. Open the cultural relic "blind box".
Relying on digital technology, a mobile phone can take you to realize such an idea instantly in the virtual world.
Not only Sanxingdui, but recently, the Great Wall, Dunhuang and other cultural and muse industry celebrities have joined hands with high-tech. With the help of cutting-edge technology, ancient civilizations have transcended time and space, eternally shining and vivid.
Alive "Top Stream"
Click on the mobile phone to scan the QR code, open an H5 page, and you can enter the digital space constructed by the "Sanxingdui Fantastic Journey" program, representing the current "Sanxingdui Archaeological Excavation Shed", the future "Sanxingdui Digital Museum" and the "Sanxingdui Digital Museum" representing the past. "The Kingdom of Ancient Shu" appeared one by one.
Entering the "Sanxingdui Archaeological Excavation Greenhouse", whether it is the swaying sound of the branches when passing through the forest, or the change of light and shadow under the sun, all are using smart details to build a realistic experience, making people immersed in the fun of archaeological excavation.
Lu Yun, senior product expert of Alibaba Cloud Intelligent Cloud Rendering Product Department and project leader of "Sanxingdui Fantasy Journey", introduced that it is the application of cloud real-time rendering technology that brings immersive interactive experience to the audience.
"In the field of cultural tourism, the cloud real-time rendering technology can have more room for imagination, and a large number of cultural and expo sites can realize the construction of virtual space, allowing the audience to have an immersive experience."
The Great Wall, which has survived thousands of years, has also "lived" with the help of digital technology.
Not long ago, in the WeChat applet of "You Great Wall", the "Digital Great Wall" created by comprehensive innovation of multiple technologies was officially unveiled, and users can immediately "traverse" to the Xipanjiakou section of the Great Wall at Xifengkou through their mobile phones.
According to Cui Xiaochun, head of the "Digital Great Wall" R&D team and vice president of Tencent Interactive Entertainment, the concept of digitalization of the Great Wall has been proposed for many years, but most products are still limited to the simple collection and display of pictures, panoramas and 3D models, and cannot provide convenient, low-cost threshold, attractive digital experience.
The development of science and technology provides new ideas and solutions for digital preservation.
"Photo scanning modeling technology helped us achieve millimeter-level measurement of the Xifengkou Great Wall. By rendering more than 50,000 pieces of massive material, we finally generated a hyper-realistic digital model of over 1 billion facets," he said. Through the "Digital Great Wall", users can not only intuitively experience the immersive scenes of the Great Wall, but also learn common sense and repair knowledge about the Great Wall through interactions such as archaeology, cleaning, masonry, jointing, brick wall repairing and support reinforcement.
With the development of digital technology, more and more cultural relics collected in museums, heritage displayed on the vast land, and characters written in ancient books are "lived", connecting with the times in a form that people like to hear.
The power to break through time and space
When it comes to Dunhuang, the most amazing thing in the world is the frescoes in the grottoes.
The murals made of soil, grass, wood, mineral pigments, etc. are exquisite and fragile. Under the action of time, aging problems such as fading, granulation, and peeling have become irreversible phenomena.
Fan Jinshi, honorary president of the Dunhuang Academy, once described the protection of the Mogao Grottoes in Dunhuang as a "race against time".
In the race against time, digital technology comes into play.
Dunhuang is one of the earliest cultural and museum institutions in China that use digital technology to collect cultural relics data.
From the 1980s to the present, Dunhuang has accumulated more than 280 digital data of cave cultural relics, and the Mogao Grottoes in the virtual world have become eternal.
A large amount of data has also been widely used in Dunhuang studies, Dunhuang grotto archaeology, Dunhuang fine art copying, and Dunhuang fresco exhibitions and many other fields.
"The permanence and reproducibility of digital technology meets the needs of cultural relics protection and management," said Liu Yuzhu, chairman of the China Cultural Relics Protection Foundation.
At the same time, the immediacy and efficiency of digital technology also meet the needs of cultural relics display and dissemination.
In the Spring Festival of 2020, due to the impact of the epidemic, the Mogao Grottoes in Dunhuang announced that they would be temporarily closed.
On February 20 of that year, based on digital technology, the "Yunyou Dunhuang" applet co-operated by Dunhuang Research Institute and Tencent was launched expeditedly.
"Through this small program, we hope to further lower the threshold for the general public to understand and understand the Mogao Grottoes, and make it possible to 'visit' the Mogao Grottoes anytime, anywhere." Deputy General Manager of Marketing and Public Relations Department of Tencent Group and Tencent New Cultural Creativity Dai Bin, executive director of the institute, said.
In the past two years, a total of 50 million users have "toured Dunhuang" through mobile phones, which is equivalent to 19 times the annual number of offline visitors to the Mogao Grottoes.
The application of digital technology is not limited to emergency measures under the epidemic, it has become an important means to extend the value of cultural and exhibition institutions.
Not long ago, the Dunhuang Research Institute and Tencent announced the creation of a "digital Buddhist scripture cave", which will restore the murals and cultural relics in the cave with a millimeter-level accuracy of 1:1, reproduce the historical situation behind the Dunhuang suicide note, and allow online tourists to "click" Travel through "history" and learn about the past and present of the Sutra Cave.
Digital technology is helping the traditional cultural and muse industry to break through the limitations of time and space, narrowing the distance with the public, especially allowing more young people to immerse themselves in the power of Chinese civilization.
predictable surprise
In recent years, my country's digital cultural protection has ushered in a good opportunity for rapid development.
Especially in 2016, six departments including the State Administration of Cultural Heritage jointly issued the "Three-Year Action Plan for "Internet + Chinese Civilization", and cultural and expo institutions across the country, as well as leading technology companies and mainstream media integration media platforms have joined in, through 5G, AR, VR , artificial intelligence and other technologies have launched a large number of digital cultural products.
The recently released "14th Five-Year Plan" and "Opinions on Promoting the Implementation of the National Cultural Digitalization Strategy" put forward new development goals for the digitalization of museums and the new experience of digital culture, which shows the country's high degree of integration of culture and technology with science and technology. Pay attention to.
Under the guidance of policies, there is a lot to be done in Wenbo + science and technology.
The archaeological work of cultural sites faces a large number of damaged unearthed cultural relics, and splicing and repairing is a major problem.
Taking the Sanxingdui site as an example, a large number of broken branches of the bronze sacred tree unearthed in 1986, after ten years of repairing, the No. 1 and No. 2 bronze sacred trees can be displayed to the public, but they are still incomplete.
Zhao Hao, associate professor at Peking University’s School of Archaeology and Museology and the head of the excavation of Sanxingdui Pit No. 8, said that this is not only a problem of the Sanxingdui site, but also a long-term problem faced by the entire archaeological community. Tens of thousands or even hundreds of thousands of cultural relic fragments cannot be efficiently and accurately determined by manpower. Completing the splicing repair, if digital technology can assist archaeologists in the identification, comparison and splicing of fragments, it will be a major breakthrough in archaeology.
Zhang Zhengyou, Chief Scientist of Tencent and Director of Tencent AI Lab and Robotics X Laboratory, believes that the cutting-edge technology of computer vision can play an assisting role in the splicing and restoration of unearthed cultural relics, as well as the digital reconstruction of the original form. The fragments of cultural relics are scanned in 3D to establish a database After that, artificial intelligence can calculate the possibility of splicing according to the color, texture, shape of the section and other information of the object, which greatly improves the efficiency.
"On the premise that the cultural relics unearthed all over the country are digitally scanned, the similar cultural relics can be efficiently identified through computer vision technology, including the similarity in shape, structure, and local texture of the objects." Chinese Academy of Sciences Shan Shiguang, a researcher at the Institute of Computing Technology, said that if archaeological data can be marked with a large amount of information such as the age or cultural attributes of cultural relics, it is a typical pattern recognition problem for artificial intelligence, which can achieve rapid comparison and assist in archaeological and cultural research.
It is foreseeable that when cultural excavations meet technology, from archaeological excavation to cultural relics protection, from value interpretation to display and dissemination, the surprises brought by the combination of the two may be far beyond imagination.
