Book labeling position acquisition method and self-adaptive labeling method and system

Abstract

The invention provides a book labeling position acquisition method and a self-adaptive labeling method and system. The book labeling position acquisition method comprises the following steps: acquiring a to-be-labeled page image; a labeling area is selected from the to-be-labeled page image, the labeling area comprises at least one labeling sub-area matched with the label in size, the proportion of characters and graphs in the labeling area is smaller than or equal to a proportion threshold value, and the value range of the proportion threshold value is 0-0.7; and outputting the position information of the at least one labeling subarea on the to-be-labeled page. The proportion of the characters and the graphs in the labeling area is smaller than or equal to the proportion threshold value, the situation that the labels cover the characters and the graphs on the to-be-labeled page can be avoided or reduced, the page readability is improved, and the optimal labeling position is automatically selected in a self-adaptive mode according to the character and graph distribution characteristics of the to-be-labeled page.

Description

technical field [0001] The invention relates to the technical field of book management, in particular to a book labeling position acquisition method, self-adaptive labeling method and system. Background technique [0002] There is a very visible sticker on the front or back cover of each book in the library. This sticker is the unique book label assigned by the library to each book. Book labels generally display the library name, barcode or QR code, and book number. When borrowing or returning books, the book information can be obtained by scanning the barcode or QR code for input into the system. [0003] In the prior art, when the labels are pasted on the books, the labels of the books are usually manually labeled, which not only has a slow pasting efficiency, but also often the labels are not evenly pasted. Therefore, automatic labeling machines have appeared. The labeling and filming system disclosed in the patent can accurately and quickly perform labeling and filming...

Problems solved by technology

[0003] In the prior art, when labeling a book, the labeling of the book is usually done manually. Not only is the efficiency of the labeling slow, but the labeling is often uneven. Therefore, an automatic labeling machine has appeared, such as the Chinese company whose publication number is CN213566881U. The labeling and film sticking system disclosed in the patent can accurately and quickly label and stick books to reduce manpower and realize automatic labeling

However, in actual use, it is found that the typesetting of the front or back cover of each book is different. If the label is placed on the same position on the front or back cover of all books, there will be a problem that the label will cover the text and graphics on the front or back cover, affecting the cover. or the readability of the back cover
