Description

Technical Field

[0001] This invention relates to the field of intelligent library equipment technology, specifically to an intelligent text recognition system for libraries. Background Technology

[0002] With social development and technological progress, the amount of knowledge created by humankind is increasing exponentially. Before the advent of e-books, most knowledge was passed down through books. China has a history of five thousand years and has produced a large number of excellent books. Over the course of history, these books have suffered varying degrees of damage, making the digital storage of these books an urgent matter. In the field of library management, rapid searching of book content is very helpful for quickly locating books. Due to the sheer number of books and the fact that early printed books did not have electronic manuscripts of the authors, the digitization of paper books is essential.

[0003] Optical character recognition (OCR) software is a powerful tool for converting paper books into electronic documents. It mainly utilizes a large number of character samples and, through the learning of complex networks, generates corresponding model files to achieve the purpose of recognizing characters in images.

[0004] Currently, similar technologies are disclosed in related patents, such as the image text recognition system disclosed in patent number 201611254376.0. This system includes an image text segmentation module, a feature image generation module, a storage module, a normalization processing module, and an image text recognition module. The image text segmentation module segments the image to be processed into sub-images containing only a single character and stores them in the storage module. The feature image generation module generates corresponding character feature images based on the font of the text to be recognized selected by the user and stores them in the storage module. The normalization processing module extracts the feature images and sub-images to be recognized stored in the storage module, performs normalization processing according to their corresponding types, and stores the processed image information in the storage module. The image text recognition module extracts the sub-images from the storage module, uses an XOR algorithm to calculate the degree of conformity between the sub-images and the feature images, and thus realizes the recognition of the character content of the sub-images.

[0005] Currently, the main function of optical character recognition (OCR) software is to recognize characters in captured or scanned images. Existing technologies for recognizing text in images first require segmenting the string into smaller images containing individual characters, and then using a specific method to recognize the segmented text. The most common method for text segmentation is projection, which involves binarizing the text in the image and then finding the boundary line between two characters using perpendicular projection, separating them based on this line. However, when the characters in the image are connected, or when the image contains Chinese characters with a left-right structure, simple projection methods struggle to achieve good segmentation results. This is why segmentation has always been a challenge in OCR recognition, and the quality of segmentation directly affects the text recognition accuracy.

[0006] Furthermore, in practical use, existing books in libraries often have issues during the recognition and imaging process. Because the pages are not properly secured, they may automatically flip back up. Using a securing device for books on desks makes each page turn very cumbersome. Therefore, it is necessary to provide an intelligent text recognition system for libraries. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide an intelligent text recognition system for libraries, in order to solve the problem that, in actual use, when books in the library are being recognized and photographed, the pages may automatically flip up because they are not pressed tightly. If books placed on desks are pressed with a clamping device, each page-turning operation is very cumbersome. Therefore, it is necessary to provide a technical problem of an intelligent text recognition system for libraries.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] An intelligent text recognition system for a library includes a desk placed indoors. A lighthouse base is fixedly installed on the top of the desk. A main support rod is installed at the top of the lighthouse base. A support arm is installed at the top of the main support rod. A lamp is installed at the top of the support arm. A lamp ring is installed at the bottom of the lamp. A camera bracket is installed on the outer wall of the lamp. An AI intelligent recognition camera is installed at the bottom of the camera bracket.

[0010] As a preferred embodiment of the present invention, the lighthouse base is configured as a conical structure, the surface of the lighthouse base is provided with a display screen, the display screen is an OLED color touch screen, and the surface of the lighthouse base is provided with a speaker.

[0011] As a preferred embodiment of the present invention, the outer wall of the lamp tube is provided with two concave clamping grooves, which are arranged vertically on the outer wall of the lamp tube.

[0012] The outer wall of the camera bracket is provided with a first clamp and a second clamp. The first clamp is slidably connected in the uppermost clamp groove, and the second clamp is slidably connected in the uppermost clamp groove. The first clamp and the camera bracket are an integral structure.

[0014] As a preferred embodiment of the present invention, the lamp ring is configured as a ring on the bottom surface of the lamp tube, and the lamp ring is disposed on the outer circular surface of the bottom surface of the lamp tube near the lamp tube. A circular lamp piece is disposed in the middle of the bottom surface of the lamp tube, and both the lamp ring and the lamp piece contain LED lights that emit light.

[0015] As a preferred embodiment of the present invention, a plurality of air vents communicating with the interior are provided between the lamp ring and the lamp sheet on the bottom surface of the lamp tube, an air suction chamber is provided inside the lamp tube, an air suction tube is provided at the top of the lamp tube, the air suction chamber is connected to the top of the air suction tube inside the lamp tube, a support frame is provided in the middle of the inner wall of the air suction tube, and a filter screen is provided at the top of the air suction tube.

[0016] As a preferred embodiment of the present invention, a motor boss is provided in the middle of the bottom surface of the suction tube, a servo motor is fixedly installed at the top of the motor boss, an output shaft extends upward from the servo motor, and a blower fan is installed at the top of the output shaft of the servo motor.

[0018] As a preferred embodiment of the present invention, a chair is placed on the side of the desk.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention places a book on top of an office desk, with a light tube positioned above the desk. The bottom of the light tube has a circular light ring and a light panel, allowing light to be evenly projected downwards onto the book's surface, increasing brightness on the open, upward-facing page. Several internal air vents are located between the light ring and light panel at the bottom of the light tube, blowing air downwards to gently and non-contactly press the open book flat. A camera bracket is mounted on the outer wall of the light tube, with an AI intelligent recognition camera at its base. This camera captures and recognizes the flattened book content, improving recognition accuracy.

[0021] This invention achieves contactless pressing by blowing air onto the surface of an open book. During the pressing process, the book is protected from damage. At the same time, it allows for easy manual flipping of the book, which helps to improve the efficiency of recognition and eliminates the tedious operation of frequently disassembling and pressing the existing manual pressing device.

[0022] This invention provides a blower fan inside the suction tube, which provides a continuous and stable airflow to the bottom of the suction tube.
