Digital protection and inheritance of culture under the background of “The Belt and Road Initiative”

Chinese culture is an important force in the construction of “The Belt and Road Initiative”. But as a result of aging, backward means of repair and other reasons, the ancient books are facing the danger of destruction. This paper intends to take the ancient literature of ethnic minorities in Yunnan as an example, aiming to do the virtual digital protection of ancient books by introducing computer graphics, image processing, virtual reality, somatosensory recognition and other new technologies in the field of information. Firstly, the minority documents are collected by means of high definition photography or scanning to establish a 3D model database, the science, high precision and permanent preservation of endangered document resources will come true. Secondly, we can construct the digital protection technology network platform of the ancient books of minority nationality in Yunnan through the combined ways of building a front desk virtual scene by X3D language and building a background application system by JAVA language. Then, through the comprehensive application of Kinect and Leap Motion somatosensory recognition technology to achieve the multi-dimensional interaction between the user and the system, it can enhance operability. Finally, the ancient literature can be displayed more vivid, more realistic and more comprehensive through the network in a wide range, so that the ancient books can be out of the geographical restrictions to achieve resource sharing.
