Embodiment 1

[0098] In this embodiment, the information of the four corners of the front color image of the bill is used to detect the incompleteness of the bill: firstly, the front color image of the bill is scanned; then the four corner areas of the bill are intercepted according to preset parameters ( Figure 7 area of ​​the oblique line in ), calculate the value of each color component in the four corner areas; sort the sum of the color components in the four corner areas; finally judge whether the bill is incomplete according to the degree of discrimination of the color values. Its specific implementation steps are:

[0099] Step 1, scan the front color image of the bill;

[0100] Step 2, intercepting the four-corner areas of the bill, and calculating the color component values ​​of the four-corner areas;

[0101] Step 3, calculate the sum of each color component of the four corner regions, and sort the sum of the color components in ascending order;

[0102] Step 4. Distinguish the...

Embodiment 2

[0105] This embodiment combines the front and back color images of the bill to comprehensively judge whether the bill is incomplete: first, use the scanning device to scan the front and back images of the bill at the same time, and reduce the image size proportionally; then divide the front and back images, and perform left and right mirror images on the back image ; Next, mark the front and back binary images; finally calculate the coincidence value of the marked target of the front and back images, and judge the incompleteness of the bill according to the relationship between the calculated coincidence value and the set threshold. Its specific implementation steps are as follows:

[0106] Step 1, scan the front and back color images of the bill;

[0107] Step 2, reducing the size of the front and back color images proportionally to reduce the amount of subsequent calculations;

[0108] Step 3, converting the scaled color image into a grayscale image, and performing binariza...

Abstract

The invention discloses a method for automatically detecting the incomplete degree of a bill or paper money. The method includes the steps of A, collecting an image of the bill, thereby obtaining a front face color image or a front face and back face color image of the bill; B, judging whether the obtained image of the bill is the front face color image or the front face and back face color image of the bill or not, carrying out the step C if the obtained image of the bill is the front face color image of the bill, and carrying out the step D if the obtained image of the bill is the front face and back face color image of the bill; C, cutting out the four corner areas of the front face color image of the bill, and judging whether the corners of the bill are incomplete or not according to the color difference degree information of the four corner areas; D, carrying out scaling down, binaryzation, left and right mirroring, connected domain marking and coincidence degree calculation on the front face and back face color image of the bill in sequence, thereby obtaining the coincidence value of marked targets in the front face and back face color image, and then judging whether the bill is incomplete or not according to the obtained coincidence value. The method and system for automatically detecting whether the bill is incomplete or not are high in detection efficiency, high in recognition rate, stable and reliable, and can be widely applied to the intelligent identification field.

Description

technical field [0001] The invention relates to the field of intelligent identification, in particular to a method and system for automatically detecting whether a bill is incomplete. Background technique [0002] When processing bills, especially when processing financial certificates such as checks or wire transfer certificates, the automated bill processing systems of banks or units require that the face of the bills to be processed must be complete. If the face of the bill to be processed is incomplete, the automated bill processing system cannot perform subsequent processing or operations. Therefore, how to quickly and effectively detect whether the bill is incomplete has become an important research object in the industry. [0003] At present, the defect detection of bank bills is generally done 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 ca...
