Embodiment Construction

[0031] With reference to accompanying drawing, further illustrate the present invention:

[0032] A method for cutting and misaligning banknote images, comprising the following steps:

[0033] 1) The banknotes are placed on the conveyor belt, and the front and back images of the banknotes are scanned by the CIS scanning equipment, and the scanning equipment obtains continuous full-size banknote images;

[0034] 2) Segment continuous banknote images into single banknote images;

[0035] (2.1), calculate the sum of the pixel values ​​of each row in the continuous banknote image, and establish a pixel value array, the length of the pixel value array is equal to the total number of rows of the image; each pixel value array element corresponds to the pixel value of a certain row of the image;

[0036] (2.2), find the row whose sum of pixel values ​​is greater than the first threshold A, the pixel value refers to the brightness value of the pixel point, and mark all adjacent rows a...

Abstract

The invention discloses a method for cutting and correcting dislocation of paper money images. The method comprises the following steps: paper notes are arranged on a conveyer belt; images on the positive sides and the back sides of the paper notes are scanned by using a CIS (corporate identity system) scanning device respectively; continuous full-size paper note images are obtained by the scanning device; the continuous paper note images are cut into single pieces of paper note images; the dislocation correction is carried out on the positive side images and the back side images respectively; and the inclination level correction is carried out on the positive side images and the back side images of the paper notes respectively. With the adoption of the method, paper note images with correct ratios and accurate positions can be provided.

Description

technical field [0001] The invention relates to an image cutting and dislocation correction method. Background technique [0002] Paper currency is the main form of general equivalents in the market, and it plays an irreplaceable role in people's social life. Along with the rapid development of market economy, many social problems also appear. Many vicious crimes are related to cash, such as robbery, kidnapping, making counterfeit banknotes, etc. It usually involves a huge amount of money, and may even be accompanied by casualties, bringing great harm to social security. The serial number of banknotes is unique, and any two real and legal banknotes will never have the same number. Therefore, before the banknotes are put into storage, the serial numbers of the banknotes must be registered. Now the registration of the serial number is automatically entered in an assembly line. Therefore, ensuring the correct proportion and position of the banknote image is a necessary condi...
