Problems solved by technology

When the machine is used frequently and is not cleaned in time, the ink dust will accumulate on both sides of the acquisition module, resulting in abnormal image signals collected by the acquisition module, resulting in low detection rate and low recognition accuracy of the sorter.
[0004] The existing sorting machines generally can only solve the above problems by manual cleaning, but this method is cumbersome to operate, and users do not know the appropriate cleaning time, which greatly reduces the user experience

[0083] see figure 1 , the first embodiment of the banknote identification method based on the dust accumulation condition of the sorting machine in the embodiment of the present invention includes:

[0084] S1. Collecting reflection spectrum images and transmission spectrum images of banknotes;

[0085] The spectrum collected by the sensor in the sorter includes white light spectrum signal, reflection spectrum signal, transmission spectrum signal, ultraviolet signal, magnetic signal and thickness signal, etc. The invention mainly uses the reflection spectrum image and the transmission spectrum image of the banknote as the target image to detect and identify the banknote, so the reflection spectrum image and the transmission spectrum image of the banknote can be collected first.

[0086] S2. Locate the four edges of the reflection spectrum image and determine whether the positioning is successful, if so, obtain the positioning image and execute steps S3 and S4, otherwise execu...

Abstract

The embodiment of the present invention discloses a banknote identification method and a sorter based on the dust accumulation condition of the sorter, which uses the gray level difference between the foreground and the background of the sensor image signal to judge the boundary of the effective area, and comprehensively uses the signals of various sensors The method of feature modification, detection direction modification, secondary scanning search edge, and finally repositioning the effective boundary of the image area can greatly improve the detection rate and recognition accuracy of the sorting machine. The sorting machine according to the embodiment of the present invention includes: a banknote inlet, a banknote outlet, a banknote return outlet, a transmission track and an identification module, wherein the identification module includes: two sets of oppositely arranged CIS image sensors and transmission light source boards, a storage module, Detection module and display module.

Description

technical field [0001] The embodiment of the present invention relates to the field of banknote identification, in particular to a banknote identification method and a sorter based on the dust accumulation condition of the sorter. Background technique [0002] With the rapid progress and application of electronic and computer technology, due to the requirements of efficiency and cost, people are more and more inclined to use financial machines to replace traditional manual banknote sorting. The sorting machine is just such a financial machine tool. It comprehensively uses computer and pattern recognition technology to realize functional technologies such as banknote identification and multi-channel delivery of banknotes. [0003] The sorting machine sorts the banknotes at high speed during the working process, and it is easy to generate friction when it comes into contact with the banknotes during operation. The ink on the surface of the banknotes and the adhesives during us...
