[0060] Specifically, each first camera 21 is uniquely bound to the first target area it collects through its unique ID, and each second camera 22 is uniquely bound to the second target area it collects through its unique ID. The image information collected by the first camera 21 and the image information collected by the second camera 22 are transmitted in real time to a file server through a network. The file server pre-processes the image information, which includes standard conversion operations such as cropping, perspective, enhancement, storage, etc. to meet the specification of image processing. Then the pre-processed image information is uploaded to an algorithm server asynchronously, and the image information is detected, segmented and recognized, and the feature inference matching is performed by the OCR algorithm recognition server. Among them, the OCR algorithm recognition server uses a neural network model to realize the positioning, segmentation and OCR text detection of the book spine area, and the image information of the book spine area contains the title, author, call number, etc. Finally, the recognized OCR content is matched through a multi-stage similarity matching algorithm model to realize the inference of the library book title, so as to realize accurate inventory recognition.

[0061] The intelligent bookshelf relies on an AI algorithm model to meet the comprehensive and accurate identification and positioning of books on the bookshelf. At the same time, the intelligent collection system can automatically update the book location information according to the identification results, automatically generate a book inventory report, generate virtual bookshelf information and real scene pictures, and provide real-time book management information for librarians and readers. Readers can quickly find the location of the required books through the self-service query system or mobile application of the library, improving the borrowing efficiency. The system can also monitor the changes of books on the bookshelf in real time, and timely discover and handle abnormal problems such as misplacement of books and off-shelf.

[0062] The control system of the intelligent bookshelf realizes efficient and accurate identification and management of books on the intelligent bookshelf in the library through the comprehensive use of image acquisition, network transmission, OCR and AI image recognition technologies. The control system not only improves the automation level of book management, but also provides more convenient and efficient borrowing services for readers. With the continuous development of technology, the intelligent bookshelf management system of the library will play an increasingly important role in the future management of the library.
