Example one
The embodiment of the invention provides a magnetic counterfeit identifying method for paper money, which can be applied to the situation that whether the magnetic characteristics of the paper money to be detected accord with the magnetic characteristics of genuine paper money or not. As shown in fig. 1, the method of this embodiment specifically includes:
and S110, detecting the magnetic value of the magnetic detection area of the paper money to be detected.
The magnetic detection area of the RMB mainly comprises a crown word number area, a national character area and a hall area. In general, the magnetic detection area of the renminbi type can be roughly divided into 18 magnetic channels, wherein 18 magnetic channels can be roughly understood as dividing the renminbi into 18 areas along the short side direction of the renminbi, and each area contains magnetic pixel points, for example, 4 magnetic channels of the magnetic detection area including the image of the people hall. It is worth noting that the dividing line between the channels is not necessarily strictly parallel to the short side direction of the rmb, since the banknote may be skewed during transport in the ATM.
The magnetic value of the magnetic detection area of the paper money to be detected is detected, the image information of the paper money to be detected can be combined, each magnetic detection area is positioned, and the magnetic sensor is utilized to count the magnetic data in the magnetic detection area.
S120, if the magnetic value of the magnetic detection area meets the set magnetic threshold condition, at least one magnetic channel included in the magnetic detection area is obtained according to the facing information of the paper money to be detected.
If the magnetic value of the magnetic detection area is determined to meet the set magnetic threshold condition, wherein the set magnetic threshold condition may be that the number of pixel points with magnetic amplitudes larger than the set magnetic threshold is larger than a set number threshold, or that the magnetic value of the magnetic detection area is larger than the set magnetic threshold.
Generally, the information of the face of the paper money to be detected is divided into four types, namely front face forward, front face reverse, back face forward and back face reverse, and when the paper money to be detected is in different faces, the position distribution of each magnetic channel included in the magnetic detection area is different. Since there may be differences in the magnetic characteristics of the channels of each magnetic channel, it is necessary to determine the position information of each magnetic channel according to the facing information of the banknote to be measured, so as to perform the channel magnetic characteristic analysis.
S130, performing magnetic counterfeit discrimination on the paper money to be detected according to the channel magnetic characteristics of the at least one magnetic channel and/or the channel magnetic characteristic difference among different magnetic channels.
And analyzing the channel magnetic characteristics of at least one magnetic channel and/or the channel magnetic characteristic difference among different magnetic channels, namely performing fine magnetic characteristic detection on the magnetic detection area to realize the magnetic counterfeit identification of the paper money to be detected.
That is, when a particular unique channel magnetic characteristic of a certain magnetic channel in the magnetic detection region is detected, the channel magnetic characteristic of the one magnetic channel, such as the channel bandwidth or the distribution rule of the magnetic amplitude, is analyzed to determine whether the channel magnetic characteristic matches the magnetic characteristic of the corresponding magnetic channel of the genuine bill; when there is a channel magnetic characteristic difference between at least two magnetic channels in the magnetic detection region, the channel magnetic characteristic difference between the different magnetic channels can be analyzed to determine whether it conforms to the magnetic characteristic difference between the corresponding magnetic channels of the genuine banknote; the method can be combined with the judgment method, so that the channel magnetic characteristics of at least one magnetic channel are analyzed, and the channel magnetic characteristic difference among different magnetic channels is also analyzed, so that whether the magnetic characteristics of each magnetic channel accord with the magnetic characteristics of the genuine money or not is judged more accurately.
According to the magnetic counterfeit identifying method for the paper money, on the premise that the magnetic value of the magnetic detection area of the paper money to be detected meets the set magnetic threshold condition, at least one magnetic channel in the magnetic detection area is analyzed, whether the magnetic detection area of the paper money to be detected meets the magnetic characteristics of the genuine paper money or not is determined by judging the channel magnetic characteristics of at least one magnetic channel and/or the channel magnetic characteristic difference among different magnetic channels, and the accuracy of the magnetic counterfeit identifying of the paper money is improved through the refined detection technical means.

When the paper money to be detected is in the front positive direction, the four magnetic channels are sequentially arranged from left to right, the three on the left side are first magnetic channels, and the rightmost one is a second magnetic channel.
As an optional implementation manner of this embodiment, the magnetic counterfeit detection may be performed on the to-be-detected banknote according to the channel magnetic characteristic of the at least one magnetic channel and/or the channel magnetic characteristic difference between different magnetic channels, specifically: detecting a channel bandwidth of at least one of the first magnetic channel and the second magnetic channel; if the channel bandwidth of the first magnetic channel is determined to be larger than the channel bandwidth of the second magnetic channel and the channel bandwidth of the first magnetic channel is within a bandwidth setting threshold region range, analyzing the magnetic signal intensity of the first magnetic channel; and if the strength of the magnetic signal of the first magnetic channel meets a set condition, determining that the paper money to be detected has the magnetic characteristics of real paper money.

Specifically, the strength of the magnetic signal of the first magnetic channel satisfies a predetermined condition, which may be: dividing the first magnetic channel into three regions, namely a first region, a second region and a third region in sequence; respectively calculating the sum of the magnetic signal intensity of each pixel point in the three regions; and if the sum of the magnetic signal intensity of the first area and the sum of the magnetic signal intensity of the third area are both larger than the sum of the magnetic signal intensity of the second area, determining that the magnetic signal intensity of the first magnetic channel meets the set condition.
As shown in FIG. 2B, the magnetic signal strength in the first magnetic channel varies from large to small and then from small to large from left to right. The magnetic signal strength in the first magnetic channel shown in fig. 2B is divided into three regions from left to right in sequence, the three regions can be equally divided according to the channel bandwidth, the sum of the signal strengths in the regions is calculated, and the negative value needs to take the absolute value and then sum. And if the sum of the magnetic signal intensities in the two side areas is greater than the sum of the magnetic signal intensities in the large middle area, determining that the magnetic signal intensity of the first magnetic channel meets the set condition. Optionally, for accuracy of the determination, after the three regions are equally divided according to the channel bandwidth, a small portion of the magnetic signal strength data at the connection of the three regions may be ignored, that is, a small portion of data on the right side of the first region, a small portion of data on the left side of the third region, and a small portion of data on both sides of the second region are ignored.
