Scanning recognition system, scanning recognition method and book scanning equipment

Abstract

The invention provides a scanning recognition system, which comprises a scanning unit, a weight acquisition unit, an alarm unit and a storage and control unit, and is characterized in that the storage and control unit is set to automatically compare pre-stored book basic weight information G with book real-time weight information G'acquired by the weight acquisition unit; and according to the forward or reverse type of the difference between the book basic weight information G and the book real-time weight information G ', judging that the book damage category is defect or wet damage, and when the book damage category is judged to be wet damage, further identifying the book wet damage degree as one of different wet damage levels according to the difference between the book basic weight information G and the book real-time weight information G'. And the signal of the alarm unit is controlled according to the identified moisture loss level. The invention also provides a scanning identification method based on a threshold value. Wet damage identification alarm and disposal of the book are achieved in book scanning through the weight detection and comparison principle, large-scale hardware development and upgrading of book scanning equipment are not needed, and the method is efficient, accurate and low in cost.

Description

technical field [0001] The invention relates to the technical field of book detection, in particular to a scanning recognition system, a scanning recognition method and a book scanning device. Background technique [0002] With the development of detection technology, the self-service borrowing and returning system of the upgraded librarian workstation has been able to automatically identify and judge the damage of books. This judgment is generally made by using the micro-camera on the scanning platform to take pictures of books before and after they are checked out. After the image data is processed and compared with the built-in software of the workstation system, it is judged whether there is any obvious damage to the book cover that was originally intact after being lent out, or whether there is further damage to the book cover that was originally only slightly damaged after being lent out , and the damage of the internal pages of the book no longer requires the libraria...

AI Technical Summary

Problems solved by technology

[0003] It is worth noting that among the many manifestations of book damage, although the damage caused by the cover or internal page defects is the most common, it is not all, at least including defacement and wet damage. Defacement is generally caused by users violating regulations. Scratches on books are often difficult to detect and repair because most of the damage is on the inner pages rather than the cover. Wet damage to books may be caused by inadvertent contact with liquids during use, or by exposure to rain, Snow, etc., can be repaired by timely discovery and certain maintenance. In theory, humidity detection is a direct way to judge whether the water content of printed matter exceeds the standard, but in fact, it has not been successfully applied in the book borrowing and returning management system. This is because the humidity detection has high requirements on the detection probe, and the response accuracy and speed are limited.
