Embodiment Construction

[0048] refer to figure 1 , a method for detecting the integrity of bill image elements in the present invention, comprising the following steps:

[0049] A. Collect the front image of the bill to obtain a color image of the front face of the bill;

[0050] B. Perform grayscale processing on the color image of the front of the bill, and then obtain the grayscale image of the bill;

[0051] C. According to the preset bill element area coordinates, a plurality of bill element area images are extracted from the bill grayscale image;

[0052] D. Performing threshold segmentation processing on the image of each bill element area to obtain binary images of a plurality of bill element areas;

[0053] E. According to the binary image of each bill element area, fill in and detect the bill element area.

[0054] refer to figure 2 , further as a preferred embodiment, the step E includes:

[0055] E1. According to the bill element area to be detected, count the number of pixels with ...

Abstract

The invention discloses a ticket image element integrity detection method and a ticket image element integrity detection system. According to the method, acquisition, gray scale conversion, element region extraction and binary processing are sequentially carried out on tickets, and thus a filling state of a ticket element region is detected according to a ratio of the number of target pixel points to a region area in the image. The system comprises an image acquisition module, a gray scale image conversion module, an element region extraction module, a binary processing module and a filling detection module. Manual operation is not needed, ticket invalidity caused by incomplete element filling during an automatic batch ticket processing process can be effectively solved, the time for manually sorting the tickets can be greatly reduced, and the batch ticket processing efficiency is enhanced. The method and the system can be widely applied to ticket detection.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and system for detecting the integrity of bill image elements. Background technique [0002] When the automatic bill processing system of the bank or unit processes the bills, it is required that the face elements of the bills to be processed must be complete. If the face elements of the bills to be processed are incomplete, the automated bill processing system cannot perform subsequent processing or operations. Therefore, how to quickly and effectively detect the integrity of bill image elements has become an important research object in the industry. [0003] At present, the integrity detection of bank bill elements is generally completed by business personnel through visual inspection. This detection method has low detection efficiency and is not conducive to batch processing of bills, and accidental errors caused by human visual inspection are unavoidable. [0004] ...
