Problems solved by technology

The problem is that it does not make full use of the convenience of machinery or operating procedures
[0011] However, in some special fields, using the convenience of operation or machinery, banknotes can be recognized multiple times, and the verification process can be added to improve the recognition accuracy of banknote serial numbers to another level. The work in this area is almost blank.

Embodiment 1

[0050] In this embodiment, firstly, according to the layout of the banknote number and the position of the banknote number on the layout, a number collection device is pre-installed at a predetermined position on the banknote conveying channel, specifically, a number collection device is installed on the "must pass" of the banknote serial number Devices, such as image sensors; only extract the image of the area that may include the number (called "number area"). The range of the number area is determined according to the size of the banknote number to ensure that the number can appear in the normal passage. within this area.

[0051] Taking RMB as an example, RMB banknotes have only one number at the corner, so there are four possible positions when the number passes through the number acquisition device set on the conveying channel, namely figure 1 in the number areas I, II, III, and IV. Such as figure 1 As shown, A1, A2, A3, and A4 indicate the situation when the number ...

Embodiment 2

[0077] In this embodiment, it is basically the same as Embodiment 1, the difference is that when it is detected that the banknote or ticket arrives at the preset detection area, the cameras on both sides are triggered to simultaneously detect the area where the number may appear in the banknote or ticket. Photograph.

[0078] see Figure 5 , the embodiment of the present invention provides a method for extracting the number of banknotes or bills, comprising the steps of:

[0079] Step S501: When the banknote to be inspected reaches the predetermined first position, the cameras on both sides are triggered to take pictures of the number area I and the number area II at the same time, and step S502 is executed;

[0080] Among them, the number area is the area where the number may appear;

[0081] Wherein, the range of the number area is determined according to the size of the banknote or ticket number;

[0082] Preferably, an optical sensor can be used to determine whether the...

Embodiment 3

[0090] In this embodiment, it is basically the same as Embodiment 2, the difference is that all possible number areas on the front and back sides are collected, and the number extracted from the front side of the detected banknote or ticket is compared and calibrated with the number extracted from the back side to determine the number.

[0091] Specific as Figure 6 shown, including steps:

[0092] Step S601: When the banknote to be inspected reaches the predetermined first position, the cameras on both sides are triggered to take pictures of the number area I and the number area II at the same time, and step S602 is executed;

[0093] The number area is the area where the number may appear;

[0094] Step S602: When the banknote to be inspected reaches the predetermined second position, the cameras on both sides are triggered to take pictures of the number area III and the number area IV at the same time, and step S603 is executed;

[0095] Step S603: Detect the collected f...

Abstract

The invention discloses a paper money or bill authenticity identification method. The method comprises the following steps that: a transparent conveying belt is arranged between a money outgoing opening and a money incoming opening; a reflector and a camera are arranged at each of the upper side and lower side of the transparent conveying belt, the reflection angles of the reflectors are adjusted, so that the images of a preset detection region on the transparent conveying belt can be projected into the lenses of the corresponding cameras; a sensing device is arranged at the preset detection region, and when sensing that paper money or bills arrive at the preset detection region, the sensing device triggers the cameras to photograph regions where numbers may appear in the paper money or bills; acquired number region images are detected, whether the number region images contain paper money or bill numbers is judged; if the number region images contain the paper money or bill numbers, the numbers are extracted from the images containing the paper money or bill numbers; and the extracted numbers are matched with a preset number database, so that authenticity identification processing is performed. The paper money or bill authenticity identification method has the advantages of small amount of redundant information and highest resolution of detection regions to be identified.

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 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] Generally s...
