JP6326239B2 - Book spine photographing system and book shelf confirmation member - Google Patents

Description

  The present invention relates to a book spine photographing system and a book shelf confirmation member.

  In bookstores, it is necessary to check inventory regularly. In many cases, bookstore inventory is checked as follows. A barcode is printed on the back cover of each book. Corresponding to the barcode reading data, a database is created in which the book name, publisher, price, author, book classification, issue date, etc. are stored as records for each book.

  The worker who confirms the inventory reads the barcode for each book with a barcode reader and stores it in a storage medium connected to the barcode reader. When the barcodes of all the stock books are read, the data stored in the storage medium is collated with the data stored in the database, and the number of stocks, total stock price, etc. for each book are obtained.

  In the above inventory confirmation work, since the barcodes of all the books are read, a huge amount of time and personnel are required, and a large expense is required.

  To facilitate inventory confirmation, a book back cover database is created in advance, the books displayed in the book are photographed, individual book back cover images are cut out from the photographed images, and collated with the book back cover database. Systems have been proposed (see Patent Document 1 and Patent Document 2).

  In the system described above, the book is scheduled to be taken by the store clerk around the bookshelves, and the time and personnel required for shooting are still large. Actually, a specialist trades the above-described system and manually asks the specialist to carry out inventory once a year. The bookstore spends a great deal of money each time, but there is a problem that the bookstore management itself is under pressure because inventory deviation occurs once a year and accurate product management is not possible. Therefore, by mounting a camera on a moving part that automatically moves with the rotation of tires, etc., the moving part automatically rotates around each bookshelf and shoots, making it possible to significantly reduce the inventory work time, which is required for shooting. By reducing the time and personnel, increasing the frequency of inventory work can lead to bookstore management without loss.

  At this time, if the photographed book image can be identified and stored in which position the book is placed, it is possible to know which book is located from which position on the right side of which book shelf. Therefore, it becomes easy to return or change the arrangement of the book. Furthermore, in order to improve customer convenience, by introducing a book search system that can be used by customers, when a book intended by the customer is displayed in a bookstore, the book can be found quickly. There is an advantage. Therefore, it is conceivable to store a photographed book image and bookcase information as a set by pasting a barcode representing bookcase information that can be identified by the bookcase on each bookcase and reading the barcode by the moving unit. . If the bookshelf can be specified, it can be specified from the photographed image how many steps from the right of the bookshelf the book is.

  However, when the above barcode is provided on each book shelf, there is a problem that the work can be started only after barcodes are set in advance for all book shelves in the book store where the inventory work is performed. If it is attached to the bottom of a bookcase so that it does not stand out, it may be removed this time and the barcode may become dirty, making it impossible to read. Therefore, it is conceivable to arrange a plate (book shelf recognition member) on which a barcode is printed on the book shelf only when photographing. However, it is necessary to prepare as many plates as there are book shelves, and there is a problem in terms of cost.
