Problems solved by technology

However, the detection of the banknote thickness signal has high requirements on the accuracy of the device, and the detection is difficult. Multiple thickness detection sensors need to be installed, and the device cost is relatively high.
The detection method of the reflective signal of banknotes uses the reflective characteristics of the adhesive tape, which not only needs to be equipped with a light sensor, but also when the adhesive tape used does not have reflective characteristics, the device will not be able to detect

Abstract

The invention discloses a pasted paper money detection method and device. The pasted paper money detection method comprises the steps of coarse positioning an acquired paper money image; acquiring a coarse positioning area image with the existence of a paste situation probably; carrying out grey level histogram statistic on the coarse positioning area image; grading based on a statistic result according to a gray value range; carrying out binarization processing and envelopment fitting on each grade of image, and acquiring an image envelope of each grade of image; carrying out straight line detection on each image envelope; when detecting that the image envelope contains two straight lines which do not belong to paper money, marking the paper money corresponding to the paper money image as pasted paper money. According to the pasted paper money detection method and the device, provided by the invention, the detection rate of the pasted paper money can be effectively improved by aiming at patterns with different grey level situations probably formed by a pasted tape according to image characteristics of the pasted paper money displayed in the paper money image, the scheme can be realized easily, and the equipment cost is saved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for detecting pasted banknotes. Background technique [0002] With the widespread use of financial equipment, the demand for equipment is rising rapidly. Banknote (banknote) receiving equipment is often used in ATM equipment of various financial institutions, automatic ticket vending machines at stations, retail stores and vending machines and other environments. Because people do not understand the use of financial equipment, it is easy to receive various poor-quality banknotes during the operation of the equipment, such as old banknotes that are pasted and spliced ​​by themselves after the banknotes are broken, or criminals use real banknotes to splice counterfeit banknotes. The spliced ​​banknotes are collectively referred to as pasted banknotes. If it cannot be detected, it will have a great impact on the reliability and security of the equipmen...
