Ancient books are the most vulnerable cultural relics. We often say that they open up and lose 60 years of life. For the purpose of protection and utilization of cultural relics, the digitization and archiving of ancient books has become a common practice. In China, large public libraries such as the National Library and the Shanghai Library, as well as the ancient books of university libraries such as Peking University and Tsinghua University, have the demand for digitalization of ancient books. Ancient books contain vast knowledge and wisdom. To a certain extent, it represents the height of wisdom that an era has ever reached, and it is also an important reason why Chinese civilization can stretch for thousands of years without interruption.
Digitization is an important means of regenerative protection of ancient books. There are three main forms of digitalization of ancient books: video, which is a high-definition scan of ancient books to achieve image browsing. The full text extracts the full text of ancient books from the image base to form a full-text search library; knowledge base, It is further annotated and indexed on the basis of the full text, which can provide more dimensions and professional applications.
Different from the scroll, it can be scanned as long as it is unfolded. Most of the ancient books can't be completely spread after being bound into a book. However, in order to protect the cultural relics, the gutters can't be taken apart; the ancient book pages are “the bobbin leaves†(the ancient books bind the pages back to back, with text One side is bound outward to form a paper tube), and the ancient paper is usually thin. If it is scanned directly, it will reveal the text on the back. It is necessary to arrange a person to lining the "coil leaf" with a softer paper than the rice paper. Visualization also has special requirements for scanning machines, such as cold light source and non-contact scanning as much as possible to reduce the loss of ancient books.
The number of OS12002V professional ancient document scanners uses projection-type non-glare cold light source technology to provide extremely sufficient protection for precious ancient books and document digitization. The high-precision true color scanning lens perfectly reproduces the original details of the original, unique 90°. The V-type platen is especially suitable for digitizing precious materials that are bound into a book and cannot be fully opened. It automatically opens the press glass, adaptively adjusts the falling speed and pressure of the V-glass, and protects the literature to the utmost extent. The user-friendly design provides users with the information. A safe, reliable and ergonomic operating environment.
