Problems solved by technology

[0002] The current ticket checking methods are mainly based on manual identification and other means. Its disadvantage is that it relies on human experience and professional skills training. A lot of repeated work is prone to various negligence and mistakes, and with the advancement of modern technology, the appearance and characteristics of counterfeit bills are almost the same as real ones. It is difficult to identify counterfeit bills only relying on human experience.

Embodiment Construction

[0014] This method mainly divides the text information into three categories: character strings, barcodes, and Chinese character information. First, the three types of information on the ticket are segmented by preprocessing means, and then the segmentation results are processed and recognized accordingly. During the identification process, these three types of information can be mutually verified, and it is possible to judge whether the identification of each type of information is accurate. The ticket is a two-dimensional image with two directions of x and y. For the scanned image, the corrected grayscale image is first obtained by tilt correction, denoising, grayscale processing and other means. First, the corrected grayscale image is moved along the y Axial projection, the minimum value point of the projection map may obtain a segmentation point, and then combine the prior knowledge of the proportion of the text height of each line of the ticket to realize the segmentation ...

Abstract

The invention discloses an automatic ticket checking method for train tickets. The automatic ticket checking method comprises the following steps: segmenting each train ticket image through pretreatment to get three types of main text information (character strings, bar codes and Chinese characters), further realizing text content identification through a mode identification means based on image processing, and realizing automatic ticket checking of the train tickets on the basis of identification. By adopting the method, the identification of the text information of the train tickets can be effectively realized, the identification rate is higher, and the identification speed is fast; and the various text information of the train tickets can be effectively got, the ticket checking of the train tickets can be realized fast, and the accuracy in ticket checking is high.

Description

technical field [0001] The invention belongs to an automatic ticket checking method for train tickets. Background technique [0002] The current ticket checking methods are mainly based on manual identification and other means. Its disadvantage is that it relies on human experience and professional skills training. A lot of repetitive work is prone to various negligence and flaws, and with the advancement of modern technology, the appearance and characteristics of counterfeit bills are almost the same as real ones. It is difficult to identify counterfeit bills only relying on human experience. With the rapid development of pattern recognition, image processing and database technology, modern technical means have opened up new research directions and methods in the field of ticket inspection. Contents of the invention [0003] The purpose of the present invention is to design a method for automatic ticket checking, which mainly uses image processing, pattern recognition an...
