The Imperial Palace, the national memory of China, was built in the fourth year of Yongle (1406) and completed in the 18th year of Yongle (1420). It has been exactly 600 years this year.

During these 600 years, the Forbidden City has remained motionless, and now it has caught up with the tide of artificial intelligence.

At the just-concluded WAIC 2020 World artificial Intelligence Conference, Shan Jixiang, former president of the Imperial Palace, gave a keynote speech at the conference, introducing how the Forbidden City uses technology to achieve cultural relics conservation and cultural dissemination.

The Imperial Palace embraces AI: leading tourists back to the Qing Dynasty

In recent years, the Imperial Palace has become a veritable online celebrity, not only tens of millions of fans on the media platform, but also a top cultural symbol through successful marketing. Since 2013, the exclusive App of the Forbidden City has been launched one after another, and so far 10 models have been produced, including "the Emperor's Day", "Forbidden City auspicious", "Daily Forbidden City" and so on.

With forums, digital museums and immersive interactions, the Imperial Palace is becoming more and more scientific and technological.

In addition to using scientific and technological means to achieve cultural dissemination, the Imperial Palace also uses AI technology to protect, restore and comprehensively display cultural relics, so that visitors can see a more complete Forbidden City.

Digital Museum: visitors can also interact with cultural relics

On December 22, 2015, after two years of construction, the Duanmen Digital Museum of the Palace Museum was finally completed and made its debut.

Duanmen is the main entrance of the Forbidden City in the past, through the collection of high-precision cultural relics data, combined with academic research, the cultural relics and historical and cultural accumulation in the digital world.

Duanmen Digital Museum was designed by the team of Tsinghua Academy of Fine Arts.

Shan Jixiang said that here, tourists can talk to more than 1200 ancient buildings and see 1500 large carpets that cannot be displayed.

For example, tourists can call a piece of calligraphy, copy it, and let the system score it after copying.

Another digital pavilion is "Digital Duobao Pavilion", which consists of 18 high-definition screens in 9 columns and 2 rows, featuring 12 categories and more than 160 objects collected in the Imperial Palace, using high-precision three-dimensional models to build a virtual "Duobao Pavilion".

In "Digital Duobao Pavilion", the audience can see the cultural relics up close.

Among them, about 50 artifacts can be touched, scaled and rotated to various angles to see the details, and seven artifacts can be further interpreted in detail to the audience through multimedia.

In addition, Digital Duobao Pavilion also uses digital means to let people understand the process of making and using cultural relics.

VR guide: panoramic view in closed areas

Digital museums not only allow people to view cultural relics up close, but also allow tourists to visit spaces that were previously inaccessible.

Shan Jixiang said, for example, that the San Xitang, the study of Emperor Qianlong, covers an area of only 8 square meters and is divided into internal and external parts by the fan. The area is so small that it is difficult to open to tourists. Previously, people could only look through the glass.

Only 8 square meters of Saxitang tourists are not allowed, but can browse through VR

After the use of digital technology, the use of high-definition projection system to build an immersive three-dimensional virtual environment with three-sided parcels, highly simulated Saxitang, visitors can also "walk into" the Sanxitang in VR, immersively enjoy the original furnishings and feel the interior space of the palace. Visitors can also enjoy themselves in ancient costumes in front of the digital screen.

In addition, some ancient buildings cannot be visited because of renovation, but visitors can still have a panoramic view of them through VR technology.

For example, Yangxin Hall is under repair this year and cannot be entered, but tourists can walk into the "Digital Heart Hall" and have a different feeling.

"tourists can sit on the throne of the emperor to approve the book and make their own seal, and the system will evaluate whether you approve it or the emperor approves it. Here, you can interact with ministers, who are very good at chatting, and each minister will say more than 500 words. Whatever you say will give you a positive response and make you happy. "Shan Jiaxiang introduced.

AI Monitoring Environment: being a "Health Doctor" of Cultural relics

In addition to digital museums, Shan also said that artificial intelligence has many applications in the field of cultural heritage protection, such as temperature and humidity in exhibition halls, monitoring of wall settlement, monitoring of termites, monitoring of diseases in ancient buildings, monitoring of visitor flow, and so on.

However, we do not yet know how the Imperial Palace uses AI to monitor the environment, but this kind of technology has long been used in the protection of other cultural relics and has become a "health doctor" of cultural relics.

For example, exposed cultural relics such as Dunhuang murals, Qin Shihuang Mausoleum Terracotta Warriors and horses, are often faced with the danger of weathering and rain erosion.

In order to solve the problem of the protection of this kind of cultural relics, Zhang Jiawan's team from the Cultural Heritage Protection and inheritance Information Technology Research Center of Tianjin University developed a preventive protection technology with the core of "Cultural relic Noumenon and risk Source Association Model".

In cooperation with Dunhuang Research Institute, the team carried out continuous annual monitoring of murals and painted sculptures in 11 caves and 47 monitoring sites.

There are four typical diseases in this kind of cultural relics: herpes, crisp alkali, nails and fissures.

The micro-change monitoring technology is used to accurately perceive and measure the small changes produced by the ontology; at the same time, the four kinds of diseases in the ontology are analyzed quantitatively with the help of image analysis, machine learning, photogrammetry and other related technologies.

The team monitored some of the murals in Dunhuang Mogao Grottoes from 2014 to 2016, and then analyzed the monitoring results, and for the first time found subtle changes in the body of 0.1 mm murals in a short period of one year. This result is generally regarded by authoritative experts in the field of cultural relics protection as a substantial breakthrough in this field.

Zhang Jiawan believes that computer graphics has great potential in cultural relic protection.

Zhang Jiawan said that this set of technology is to find a way to deal with risks. "We need to build an integrated platform for perception, analysis, evaluation and response." "

At present, the same technology has been applied in heritage sites such as Dunhuang Research Institute, Summer Palace and Labrang Temple.

AI+ art protection: broad world, bright future

The above is only the tip of the iceberg of science and technology in the protection of cultural relics. Around the world, AI technology has been providing convenience for many cultural relics restoration workers, so that more cultural relics "alive".

The Imperial Palace, with the blessing of science and technology, gives more and more surprises to tourists.

Shan Jixiang said, "through artificial intelligence, how to make museum culture into thousands of families, this is a never-ending topic." "what has been achieved now gives us reason to believe that this subject will be fruitful in the end.
