Embodiment Construction

[0028] In view of the shortcomings of the reflective imaging mechanism used in the prior art to identify the serial number of banknotes, the present invention proposes to use a transmission imaging mechanism to obtain the serial number of banknotes, which can simplify the hardware structure, reduce the volume of the banknote detector, reduce hardware costs, and control the program flow. Also more simplified. Specifically, using transmissive imaging, capturing an image once in the transmissive mode is equivalent to superimposing the image information on the front and back sides to form a new image. In this way, for an implement using CMOS transmission imaging, two groups (light source and image acquisition unit) can be provided. For implements with CIS transmission imaging, refer to figure 1 , using CIS imaging, only place a CIS above or below the banknote, and place a light source on the corresponding opposite side. When the currency inspection equipment is started, the ban...

Abstract

The invention discloses a method for recognizing paper currencies and tickets, which comprises the following steps of: acquiring the sequence numbers of paper currencies and tickets; and recognizing the truth of the paper currencies according to the acquired sequence numbers of the paper currencies and the tickets. The invention also provides a corresponding device for recognizing paper currencies and tickets. The invention proposes the scheme that a transmission imaging mechanism is used for acquiring the sequence numbers of the paper currencies and the tickets, and the paper currencies and the tickets are recognized and managed according to the acquired sequence numbers. According to the invention, the hardware structure can be simplified, the volume of a currency detector is reduced, the hardware cost is lowered and the program control flow is further simplified.

Description

technical field [0001] The invention relates to the technical field of image processing and identification, in particular to a banknote and coupon identification method and device. Background technique [0002] Maintaining financial order and the interests of the public and preventing counterfeit money from flowing into the market are issues of particular concern to financial management institutions. Reflective imaging methods based on CMOS, contact image sensor CIS, CCD and other image acquisition equipment are widely used in traditional currency counters, sorting machines and other banknote detection machines. As the counterfeit currency production technology is getting higher and higher, it is necessary to propose more efficient and effective means to solve various counterfeit currency and counterfeit currency identification problems encountered in reality. [0003] The existing banknote identification system mainly uses CMOS, CCD or CIS reflective imaging to obtain the ...
