Abstract

The embodiment of the invention provides a personal library construction method and device, and the method comprises the steps of building a hardware platform, and obtaining a high-quality text image;secondly, performing morphological preprocessing on the image so that target information is enabled to be highlighted and interference can be reduced; thirdly, further correcting the distortion of the image based on an affine transformation and projective geometry algorithm, and carrying out the edge cutting of the image; and finally, carrying out OCR on the processed image, and carrying out personalized retrieval based on keywords or chapter names on the recognized text. According to the method, paper text electronization can be realized anytime and anywhere, the recognition rate of the existing character recognition technology is improved, and a personal library is quickly constructed.

Description

technical field [0001] The invention relates to a construction scheme of a digital library, in particular to a personal library construction method and device. Background technique [0002] At present, the most common books and documents in daily life are mostly paper products. Paper resources are more in line with people's habit of searching and reading. However, with the development of computers and the Internet, literature is moving in the direction of modernization, electronicization, and networking. The construction of a personal digital library can be divided into two parts: electronicization and information retrieval. [0003] The electronicization of paper documents is inseparable from professional scanning equipment and skilled operating skills, but this is too demanding for mass users. At the same time, it is precisely because the threshold for digitization is too high that the current digitization of books can only target bestsellers. This electronic process i...
