Description

Book location management device and its method {LIBRARY BOOK POSITION MANAGEMENT APPARATUS AND METHOD THEREFOR}

The present invention relates to a book location management device and method for determining whether a book is properly located in a library and notifying a user of an incorrectly located book.

As in libraries, books are displayed by groups, and it is common for users to search for books by an identification number according to a category corresponding to the group. Through the location of the library according to the identification number, the location of the bookshelf, etc., the user can physically find the book.

However, in the case of a book that is kept inside the library but is not in its original location, the searched book cannot be found in the location where the original book should be located with the corresponding identification number. You may have to browse the entire library, or you may not be able to find the book you are looking for.

These Owitch books are inconvenient for the library manager to find them with the naked eye. For this inconvenience, the location of the book can be tracked using a tag such as RFID. However, these location tags may be inaccurate and may not function until the book is equipped with the tag.

Therefore, there is a need to find Owitch's book in a way other than the naked eye at low cost.

When the target area (target_area) includes a plurality of categories, the partitioning module 110 may set one of the plurality of categories as the reference area (ref_area) according to any one of a preset policy and user selection. The preset policy sets a certain category among a plurality of categories as the reference area (ref_area), or when the local location determination module 140 determines a plurality of local locations for the same bookshelf image (img), from a wide area to a narrow area. There may be a policy to sequentially set as a reference area (ref_area) in the category of .

When a user selects a category in the display unit 230 that displays a plurality of categories in the bookshelf image img and augmented reality, the selected category may be set as the reference area ref_area.

The target area (target_area) may be a stream area 329 generated based on an image group having a plurality of bookshelf images (img). Referring to FIG. 4 , the user may pass through a series of books with the photographing unit 210 and take pictures. The segmentation module 110 may define both the image taken at the first time t1 and the image taken at the second time t2 as the target area target_area, or a part thereof as the target area target_area. .

The reference information extraction module 120 may extract reference information (ref_info) for allowing books to belong to the same group in the reference area (ref_area). The reference information (ref_info) may be any one of the call codes of the book or a part of the information (title, publisher, author) displayed on the spine of the book. Since the books in the library are labeled with the call number of the book written on the back of the book, it is preferable that the reference information (ref_info) is the call number.

Claim marks may include separate marks, classification marks, book marks, and secondary marks.

An asterisk is a symbol attached to special data.

The classification code is a grouping of similar items by the subject of the book with the same symbol. In the case of Korea, it is desirable to follow the Korean Decimal Classification Table (KDC). A classification code according to the Korean Decimal Classification System may include at least a part of mainstream, strong, essential, and detailed items.

The book symbol may consist of an author symbol and a copyright symbol. The author's symbol may consist of a part of the author's indication (for example, 'surname') and digitization of it according to the author's symbol method. The author's symbol may be part of the book title (first letter, initial consonant, etc.).

The secondary symbol may be at least one of a number indicating the number of a book and a duplicate indicating a duplicated book.

The reference information (ref_info) may be any one of the call symbols or a part of the corresponding symbol. For example, the reference information (ref_info) may be composed of the mainstream and strong headings of classification codes.
