What is Silk Road?

The Silk Road consists of the land Road and the sea Road. The Land Silk Road originated in the Western Han Dynasty (202-8 BC). It starts from the capital Chang'an (now Xi'an), passes through Gansu and Xinjiang to central and West Asia, and connects Mediterranean countries. Its initial function was to transport silk and became a comprehensive trade road during the Ming Dynasty. The Sea Road" is a maritime channel for transportation, trade and cultural exchanges between ancient China and foreign countries. The sea silk road was formed in the Qin and Han Dynasties (221 BC-220 AD), developed in the Sui Dynasty (581-618) and flourished in the Tang, song, yuan and Ming Dynasties (618-1911).

In June 2014, UNESCO designated the Chang'an-Tianshan corridor of the Silk Road and the Beijing-Hangzhou Grand Canal as World Heritage Sites.

Digital Silk Road Project

Digital Silk Road Project is a digital humanities research project about creating digital archives of cultural heritage along the silk road based on collaboration between informatics and humanities. Now the recent projects they are working on include as follows: Digital Archive of Toyo Bunko Rare Books, Database of Ruins in Silk Road, Stein Placename Database, Digital Maps of Old Beijing, DSR Silk Road Music, etc.

History and Members

Digital Silk Road Project was Organised by National Institute of Informatics (NII) in 2001, and led by KITAMOTO laboratory, Which is focused on various methodologies for the better handling of image data. It involves Team members from various research institutions and universities across Japan and China.

Purpose and Audience

The purpose of the digital silk road project is to archive the huge amount of cultural resources that have been collected and studied from the ancient to the current, and inherit those resources for the future. They wish to Improve accessibility to those cultural resources for people who has interests in it to actually see and use those resources.

Contents and Technologies

To realize the goals, various information technologies are used in the research. Image Information Processing and GIS are used to organize database of ruins and digital maps in the silk road. Different Gazeteers of the sites along the silk road are created and each one of them has its own database, researchers can find the details they need by searching the key words. 3D and Virtual Reality are used to reconstruct some important cultural heritage such as Citadel of Bam in Iran, which is totally destroyed by the earthquake. Their goal is to use the virtual reconstruction to the physical reconstruction in the future. Another example is Bezeklik Caves in China, which is famous for great wall paintings preserved under the sand but were completely removed by German expedition Team and brought back to Germany. The project team moved the wall paintings from books to a 3D space so that people in other countries can see and imagine the wall paintings in their original forms.


3D Reconstruction using Computer Vision

They are now doing research on the following topics.

~3D reconstruction from multiple photographs. They collect tourist and recording photographs from around the world, and construct 3D models from them. Due to the lack of camera parameters, less linear features, and small number of photographs, this method is technically very difficult at this moment.

~3D reconstruction of video taken from a helicopter. They are exploring a method for reconstructing 3D models from video taken from a helicopter.

~Overlay of photographs on digital elevation models. They are exploring a method for making pseudo 3D models by overlaying photographs on digital elevation models.

Support

Since 2001, the projects are financially supported by the following institutions:

•Japanese Society for the Promotion of Science (JSPS)

•Ministry of Education, Culture, Sports, Science and Technology (MEXT)

•National Institute of Informatics
