Example one
Fig. 1 is a flowchart of a hidden magnetic stripe banknote identification method according to an embodiment of the present invention, where the present embodiment is applicable to a banknote identification situation, and the method specifically includes the following steps:
s110, determining the magnetic point position of the paper money placed in the area to be detected;
in this embodiment, the banknote is a banknote to be detected, and the region to be detected may be a region where the banknote should be placed in the process of extracting an image or identifying/extracting features of the banknote. The safety line area (metal strip area) of the paper money is printed by using a magnetic anti-counterfeiting technical material; the area without the magnetic signal under the magnetic sensor is a background area, the difference between the magnetic data with the magnetic signal and the magnetic data value of the background area is larger, the magnetic data of the paper money can be conveniently collected, and the magnetic areas of the safety lines are in strip distribution. The current magnetic stripes are mainly divided into two types, namely a hidden magnetic stripe and a semi-hidden magnetic stripe. The semi-hidden magnetic stripe is buried in the paper money, the non-hidden part has magnetism to penetrate out, and the hidden part has no magnetism, so that magnetic wave crests and wave troughs can be generated. Therefore, different specific rules of the wave crests and the wave troughs of the magnetic stripe can be formed through different arrangement rules, and the conventional magnetic stripe counterfeit identification is realized through the specific rules. The hidden magnetic strip is completely embedded in the paper money, has no regular wave crest and wave trough, and only has one magnetic wave crest at each end of the paper money. The embodiment is mainly directed to the hidden magnetic stripe, and the magnetic point positions of the embodiment are the magnetic point distribution positions of the magnetic security thread of the hidden magnetic stripe paper money.
S120, identifying the length of the magnetic strip according to the position of the magnetic point to obtain the width of the paper currency;
in this embodiment, the size of the banknote is often an important criterion for identifying the denomination version of the banknote. As shown in fig. 2, because the hidden magnetic stripe is completely embedded in the paper money, there is no regular wave peak and wave trough, and only two ends of the paper money have the magnetic wave peak 21 and the magnetic wave peak 22, the length of the magnetic stripe of the hidden magnetic stripe paper money can be obtained by detecting the distance L between the magnetic blocks at two ends of the paper money, and the corresponding length of the magnetic stripe is also the width of the paper money.
And S130, determining the currency value version of the paper currency according to the width of the paper currency.
In this embodiment, each denomination of rmb has different banknote sizes, and different versions of rmb have correspondingly different sizes. The embodiment can perform magnetic stripe detection on paper money with various currency value versions in advance, store the detected magnetic stripe length, namely the paper money width, in the database, and match the detected magnetic stripe length of the paper money to be detected with the data of the database to obtain the currency value version of the paper money to be detected according to the step 120.
The technical scheme of the embodiment of the invention determines the magnetic point position of the paper money placed in the area to be detected; identifying the length of the magnetic strip according to the position of the magnetic point to obtain the width of the paper money; the currency value version of the paper currency is determined according to the width of the paper currency, the problem that the conventional magnetic strip processing method for the hidden magnetic strip paper currency is time-consuming is solved, and the effect of reducing time consumption of counterfeit identification is achieved.
Example two
Fig. 3 is a flowchart of a hidden magnetic stripe banknote identification method according to a second embodiment of the present invention, which is further optimized based on the second embodiment, and the method specifically includes:
s210, selecting a magnetic stripe channel where a paper money magnetic stripe is located from a plurality of detection channels, wherein the plurality of detection channels are longitudinally divided based on the to-be-detected area, and the number of the magnetic stripe channels is one or more;
in this embodiment, the plurality of detection channels are channels divided into regions to be detected in a longitudinal direction, and the longitudinal direction is a direction parallel to the magnetic security thread of the banknote. The longitudinal dividing mode of the area to be detected meets the requirement that whether the paper money is right side up or right side down, the paper money is right side left or right side left, and as long as the paper money is placed in the area to be detected in a non-inclined mode, the magnetic safety line of the paper money is located in one of the channels. Although the position of the magnetic security thread is fixed for a particular type of banknote, the specific position of the magnetic security thread is uncertain because the front and back, left and right directions of the banknote are uncertain during the banknote image extraction or banknote feature recognition/extraction. The embodiment can count the number of the magnetic points in the plurality of channels, and when the magnetism of the magnetic strip is stable and the number of the magnetic points is basically and uniformly distributed in one or two channels, the channel with the largest number of the magnetic points in the channel is the channel with the largest number of the magnetic points in the magnetic strip.
S220, when the number of the magnetic stripe channels is multiple, combining the magnetic points in the multiple magnetic stripe channels to generate the magnetic point positions.
In this embodiment, when a banknote is tilted, the magnetic security thread of the banknote may be covered by two consecutive channels (empirically, three or more channels will not be covered even if the banknote is tilted any more), and therefore, in such a case, determining the position of any one channel as a magnetic security thread is inaccurate. Therefore, the number of magnetic security line segments per two channels needs to be counted. For example, the region to be detected is divided into N channels, channel 1, channel 2 … …, channel N-1, and channel N, respectively. The magnetic strips are often distributed in two or more channels, so that the magnetic points in the channels where the magnetic strips are located need to be combined to obtain a complete magnetic strip.
S230, identifying the length of the magnetic strip according to the position of the magnetic point to obtain the width of the paper currency;
in this embodiment, because the hidden magnetic stripe is completely buried in the paper currency, there is no regular wave crest and wave trough conventionally, and only two ends of the paper currency have a magnetic wave crest respectively, the magnetic stripe length of the hidden magnetic stripe paper currency can be obtained only by detecting the distance between the magnetic blocks at two ends of the paper currency, and the corresponding magnetic stripe length is also the width of the paper currency.
And S240, determining the currency value version of the paper currency according to the width of the paper currency.
In this embodiment, magnetic stripe detection may be performed on paper money of various denomination versions in advance, the detected length of the magnetic stripe, that is, the width of the paper money, is stored in the database, and when the length of the magnetic stripe of the paper money to be detected is detected according to step 230, the length of the magnetic stripe may be matched with data in the database to obtain the denomination version of the paper money to be detected.
And S250, if the width of the paper currency is within a third preset threshold range, carrying out image detection on the paper currency to identify the version of the paper currency.
In this embodiment, since there may exist the same banknote width for different versions of the same denomination in some banknotes of rmb, for example, the banknote width for the 1999 version of 100 yuan banknotes is the same as the banknote width for the 2005 version of 100 yuan banknotes, since the banknote width for this type is fixed, a third preset threshold range may be set, and a certain error may be added to the fixed banknote width. The third preset threshold range can be one or more, and respectively corresponds to threshold ranges of the same currency value, different versions and the same banknote width. When the width of the paper money to be detected is matched with the third preset threshold range, image detection is required to identify the version of the paper money.
S260, detecting whether one or more magnetic point positions are included in a preset area, wherein the preset area is a non-hidden magnetic stripe magnetic point display area;
in this embodiment, the non-hidden magnetic stripe magnetic dot display area may be the other part of the conventional hidden magnetic stripe magnetic dot display area, and since the hidden magnetic stripe is completely embedded in the paper money, there is no conventional regular peak and valley, and only one magnetic peak is respectively located at each of the two ends of the paper money, the conventional hidden magnetic stripe magnetic dot display area is the two end parts of the paper money, and the area except the two end parts of the paper money is the non-hidden magnetic stripe magnetic dot display area. For example, the middle part of the magnetic stripe except for two ends can be hidden for the paper money, and the position is not limited in this respect. When the paper money is defective, the magnetic strips are distributed with abnormal bulges, so that the damage of the paper money can be quickly detected.
And S270, excluding the magnetic points with the magnetic amplitudes within the range of the first preset threshold value in the magnetic point positions in the preset area.
In this embodiment, the data existing between the magnetic amplitude 2000 and 4000 is referred to as a peak, based on the magnetic amplitude 2000, i.e. the background; magnetic data present below a magnetic amplitude of 2000 is referred to as a valley. In order to eliminate the external environment, the banknote validator itself, etc. which may generate noise, the data between the threshold magnetic amplitudes 1850 and 2150 is defined as noise, and the first predetermined threshold range may be the magnetic amplitudes 1850 and 2150. The boundary between the magnetic data values of the magnetic dot signal and the background signal changes correspondingly with the scanning precision of the magnetic sensor, so that different boundaries between the magnetic data values can be obtained with different scanning precisions, which is not described herein. The magnetic data can be subjected to filtering processing by using Fourier transform and inverse Fourier transform, so that the influence of noise on magnetic signals is eliminated, and the noise mainly refers to background signals, thereby further improving the accuracy of magnetic data acquisition.
And S280, analyzing the magnetism of the magnetic point position in the preset area to judge the damage condition of the paper money.
In this embodiment, after the interference condition that is noise is eliminated, there are generally two conditions for the distribution of magnetic dots at the magnetic dot positions in the preset area for the hidden magnetic stripe. In the first situation, the paper money is damaged, and the magnetic strip is exposed and can be magnetically displayed; the second case is where another magnetically attached object is on the note. Optionally, the analyzing the magnetism of the magnetic point position in the preset region to determine the damage condition of the banknote includes: if the magnetic amplitude of the magnetic point position in the preset area is within a second preset threshold range, the paper money is a first type of paper money, and the first type of paper money comprises paper money splicing and/or paper money breakage; and if the magnetic amplitude of the magnetic point position in the preset area exceeds a second preset threshold range, the paper money is the second type of paper money, and the second type of paper money is the paper money carrying magnetic attachments.
In the embodiment, the second predetermined threshold range is a magnetic amplitude range of a conventional stable magnetic stripe, and may be, for example, 0-1850 and 2150-. If paper currency suffers damage, for example, paper currency concatenation or paper currency breakage can lead to the paper currency magnetic stripe to expose, can show by magnetism under magnetic sensor's detection, because the magnetism of magnetic stripe is very stable, the amplitude has certain scope, consequently, can set for this amplitude scope to the second and predetermine the threshold value scope, can confirm through judging amplitude altitude variation that the magnetic stripe exposes to show that paper currency has suffered damage, regard as the condition such as concatenation or defect promptly. When the magnetic amplitude of the magnetic point position in the preset area exceeds the second preset threshold range, the magnetic property of the magnetic point position in the preset area is unstable, and the fact that the magnetic point position in the preset area is generated on the paper money by other magnetized attached crops can be directly screened and judged. Optionally, if the magnetic amplitude of the magnetic point position in the preset region is within a second preset threshold range, the method further includes, after the banknote is a first type of banknote: and carrying out image detection on the paper money so as to identify the first type of paper money as the paper money splicing or the paper money breakage.
In this embodiment, to the detection of hidden magnetic stripe, the paper currency is destroyed, when the circumstances such as concatenation, damage appear, detects the going on that can be quick through the magnetic stripe and detects. The image of the damaged paper money is different from the image of spliced paper money, the boundary of the damaged paper money is irregular, for example, the spliced paper money is saw-toothed, the spliced paper money can be in a slit shape, and further, when the spliced paper money is spliced perfectly, the spliced paper money is difficult to identify through image detection. Therefore, the embodiment can eliminate the paper money of the damaged type of the paper money so as to obtain the paper money of the paper money splicing type, when the spliced paper money is spliced perfectly, the spliced paper money can be quickly detected through magnetic detection under the condition that the spliced paper money is difficult to identify through image detection, and an effective judgment basis is provided for a splicing algorithm.
According to the technical scheme of the embodiment, whether one or more magnetic point positions are included in a preset area is detected, wherein the preset area is a non-hidden magnetic stripe magnetic point display area; excluding magnetic points with magnetic amplitudes within a first preset threshold range in the magnetic point positions in the preset region; the magnetism of the magnetic point position in the preset area is analyzed to judge the damage condition of the paper money, the problem that the spliced paper money is difficult to identify through image detection when the spliced paper money is spliced perfectly is solved, and the effect of improving the paper money splicing detection accuracy is achieved.
