Technical field

The invention relates to a device, in particular to a method and an auxiliary device for scanning a book archive page.

Background technique

A book is a book and text bound into a book. In a narrow sense, it is a collection of paper with text and images. In the original Chinese classics, books include books, pictures, pictures and other publications. Books are words, pictures and other symbols, which record various knowledge on certain materials, clearly express ideas, and make books in volumes, an important tool for accumulating various knowledge and ideas and accumulating human culture. With the development of history, it is constantly changing and changing in terms of writing style, materials used and binding forms, and form.

When scanning the book archive page, the existing flip book scanner must open the book file at an angle of 90° or more, and then use the imaging device to directly take photos of the page for imaging processing. This type of scanning is more practical for files with thin pages and low binding lines. In most cases where a flip book scanner is used, most of the book files that need to be scanned are files with thicker books and higher binding lines, and even the contents of the pages are very close to the binding line. For such a book file to be scanned, it is necessary to open A 90° or larger angle will cause damage to the book file. Often, these books that need to be scanned are very valuable. Once damaged, it will be a huge loss, so the existing scanning methods and devices are not satisfied. nessecery.
