Example Embodiment

[0046] Example one

[0047] In this embodiment, firstly, according to the layout of the banknote numbers, and according to the position of the banknote number on the layout, a number collection device is pre-installed on the banknote conveying channel. Specifically, the number collection device is installed on the "only way" of the banknote serial number. Devices, such as image sensors; only extract images of areas that may include numbers (called "number areas"). The range of the number area is determined by the size of the banknote number to ensure that the number can appear in the normal passage. Just within this area.

[0048] Taking RMB as an example, RMB banknotes have only one number located at the corner, and there are four possible positions when the number passes through the number collection device set on the conveying channel, namely figure 1 The number areas in I, II, III, IV. Such as figure 1 As shown, A1, A2, A3, and A4 indicate the situation when the number area ...

Example Embodiment

[0063] Example two

[0064] In this embodiment, it is basically the same as the first embodiment. The difference is that the process of obtaining the banknote number requires two operations, that is, the first operation is as described in the first embodiment, and the second time is to change the direction of the banknote and then do it again. Set up two number collection devices (image sensors), in figure 1 Shown in positions Q1 and Q3, or positions Q2 and Q4.

[0065] After the first detection, the total number of banknotes is known. In the process of counting the front and back of the same bundle of banknotes, the number of a certain banknote in the first time and the number of the same banknote when the banknote is counted on the reverse side must be complementary to the total number of banknotes. And the position where the number appears can also be calculated according to the position of the first appearance. Specifically, Q1 and Q3 are symmetrical, that is, the first time ...

Example Embodiment

[0070] Example three

[0071] In this embodiment, according to the position of the banknote number, two number collection devices are arranged at the predetermined position of the banknote transport channel, such as Figure 5a and 5b As shown, two number collection devices (image sensors) are set at positions Q1 and Q2 (or positions Q3 and Q4).

[0072] Assuming that number collection devices (image sensors) are installed at positions Q1 and Q2, refer to Image 6 , The method for obtaining banknote numbers provided in this embodiment includes:

[0073] S201: When the banknote to be inspected reaches a predetermined position, images of the number area I and the number area II of the banknote are respectively collected;

[0074] S202: Determine whether the image of the number area I and the number area II contains a banknote number;

[0075] If the image contains a number, go to step S203; otherwise, go to step S204;

[0076] S203: Extract the banknote number from the image;

[0077] S204, ...

Abstract

The invention discloses a method for acquiring a number of a paper currency or a financial bill. The preset position on a conveying passage is provided with a number acquisition device according to the layout position of the number. The method comprises the steps of: acquiring a regional image where the number may appear when the paper currency and the financial bill to be detected reaches the preset position; detecting the regional image, and judging whether the regional image contains the number of the paper currency; and extracting the number from the image. The invention also provides a device for acquiring the number of the paper currency or the financial bill, which comprises an image acquisition unit, a detection unit and a number extract ion unit. The invention also provides a corresponding method and a corresponding device for identifying the paper currency or the financial bill. According to the invention, only a region which may contain the number needs to be extracted, which can ensure that the processed redundant information amount is minimum, the resolution of the region to be identified is highest, the useful information amount is increased, and the identification accuracy is improved, so that the number of the paper currency or the financial bill can be quickly and accurately acquired and can be identified and managed.

Description

technical field [0001] The invention relates to the field of information and image technology, in particular to a method and device for acquiring numbers of banknotes and coupons, and a method and device for identifying banknotes and coupons. Background technique [0002] The serial number (or crown code) printed on banknotes and bills is a unique sign identifying the identity of a single banknote or bill. In addition to special anti-counterfeiting marks (such as watermarks, etc.), in the management of banknotes (or other valuable securities, bills), the identification of serial numbers (or crown codes) of various banknotes and bills becomes banknotes and bill management. And an important means of determining the authenticity to a certain extent. Banknotes need to pass through various mechanical devices (such as banknote counters and banknote detectors) throughout their life cycle, and there is a need to identify banknote serial numbers (or called serial numbers). [0003]...
