Abstract

The invention discloses a method for realizing rapid page number recognition based on template matching, aiming at the problem of low accuracy of page number recognition and scanning due to the inability to solve the problem of number concatenation in the page number recognition in the prior art; in this application, the page number is segmented skillfully And image normalization processing, can simply and quickly solve the problem of page number sticking and improve the accuracy of page number recognition, improve the overall scanning accuracy, and overcome the existing technology to solve the problem of page number sticking and waste a lot of scanning time, affecting scanning efficiency and scanning accuracy In order to solve the technical problem, the template and the image of the page number to be detected are both normalized, which improves the matching efficiency between the two in the later stage and thus improves the scanning efficiency; at the same time, this application cleverly combines the page number of the next page The comparison of page numbers avoids the situation of wrong turning and missed scanning, and overcomes the technical difficulties of continuous scanning of books in the prior art; this application is applicable to the field of intelligent recognition in machine vision industrial applications.

Description

technical field [0001] The invention belongs to the field of intelligent identification in the industrial application of machine vision, and in particular relates to a method for realizing rapid page number identification based on template matching. Background technique [0002] With the popularization of computer and network technology, electronic documents are accepted by more and more people because of their advantages of easy storage and utilization, quick and easy dissemination. Therefore, the transformation of the original paper-based materials into electronic documents, that is, the digitization of paper documents, is increasingly used in daily office work and library material management. [0003] As a new digital method of paper documents, non-contact scanning, compared with contact scanning, can avoid the problem of dismantling the original and avoiding damage to the original, and has been used more and more, but its problems also hinder its further popularization....
