Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection, in particular to a non-contact rapid banknote counting method, system, device, storage medium and program. BACKGROUND

[0002] With the issuance of the new version of the RMB, the circulation of the new and old versions of the RMB in the market gradually increases, and the new and old versions of the RMB differ in color, size, anti-counterfeiting technology, etc. The traditional contact type banknote counting machine cannot accurately identify different versions of the RMB when dealing with mixed new and old versions of the RMB, resulting in reduced counting efficiency, and even miscounting and missing counting problems. Therefore, how to quickly and accurately complete the mixed counting of the new and old versions of the RMB has become a problem to be solved.

[0003] With the progress of science and technology and the development of economy, the RMB, as the legal currency of China, its anti-counterfeiting technology is also constantly updated and upgraded. However, with the issuance of the new version of the RMB, the new and old versions of the RMB circulate in the market, and due to the non-uniformity of the anti-counterfeiting marks, it brings great identification challenges to the banknote counting machine.

[0004] The currently known banknote counting machine mainly works based on the contact principle. This type of banknote counting machine contacts the banknote through mechanical or electronic means and relies on specific sensors and algorithms to identify the denomination, quantity and other information of the banknote. The new and old versions of the banknote may differ in printing process, pattern design, etc., which may affect the identification accuracy of the banknote counting machine. Especially for some newly launched versions of the banknote, if the software or database of the banknote counting machine is not updated in time, it may not be able to identify or misidentify the banknote.

[0005] In addition, due to the limitation of the working principle of the banknote counting machine, when dealing with a large number of banknotes at high speed, it often has problems such as reduced identification speed and reduced accuracy. This not only affects the use efficiency of the banknote counting machine, but also brings potential risks to the financial safety of financial institutions and individuals.

[0006] Therefore, in view of the problems existing in the identification of the new and old versions of the RMB by the banknote counting machine, it is urgent to invent a non-contact banknote counting method that can accurately and quickly identify the new and old versions of the RMB to improve the efficiency and accuracy of banknote counting and ensure the safety of funds.

[0042] The embodiments of the present disclosure are described in detail below in combination with the drawings.

[0043] The embodiments of the present disclosure are described below through specific and concrete examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all. The present disclosure can also be implemented or applied by other different specific embodiments, and the details in the specification can be modified or changed based on different views and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present disclosure.

[0044] It should be apparent that the aspects described herein can be embodied in a wide variety of forms and that any specific structure and / or function described herein is merely illustrative. Based on the teachings herein one skilled in the art should appreciate that an aspect described herein can be implemented independently of any other aspects and that an aspect described herein can be implemented both as any claim dependent on another and as an independent claim or claims. One skilled in the art should appreciate that an aspect described herein can be implemented as any one or more of a method, a device, a system, a computer program product, or any one or more combinations thereof.

[0045] In addition, in the following description, specific details are given to provide thorough understanding of examples. However, one skilled in the relevant art will understand that the aspects described herein can be practiced without these specific details.

[0046] The embodiment of the application provides a non-contact rapid banknote counting method, a system is built, a linear laser light source and a sensor are integrated, the linear laser light source is used for projecting light on the banknote to be counted, a clear laser line is formed, and the sensor is responsible for capturing the projection image of the laser line on the banknote. This design enables the system to non-contactly acquire the feature information of the banknote, avoids the wear and pollution that can be caused by the traditional contact type banknote counting, and can quickly complete the banknote counting, thereby improving the banknote counting efficiency and accuracy.

[0047] First, a system containing a linear laser light source and a sensor is built. The linear laser light source can project a stable and clear laser line, and the sensor is responsible for capturing the projection image of the laser line on the banknote in real time. This design enables the system to non-contactly acquire the feature information of the banknote during the transmission of the banknote, thereby providing a data basis for subsequent identification and processing.

[0048] The long edges and short edges of a certain number of banknotes are respectively aligned by manual operation and then placed into the detection system, the center position of the banknote is fixed by a set of relatively clamped clamps, and the banknote is placed in a horizontal position. Under the control of a matching motion mechanism, the clamped banknote is placed at the detection position of the system. A set of linear laser sensors is arranged around the banknote at the detection position, the laser line emitted by each sensor is orthogonal to the corresponding edge of the banknote, and the projection direction of the laser is perpendicular to the edge of the banknote. The camera target surface of each sensor can capture the complete laser stripe image irradiated on the corresponding edge of the measured banknote, and the light stripe in the image is along the horizontal direction.

[0049] The collected images are processed and analyzed. Since the projection of the line laser on the banknote forms a light strip, when two adjacent banknotes pass through, the position of the light strip signal will change abruptly. The system can accurately distinguish the two adjacent banknotes by identifying this abrupt signal, thereby avoiding confusion and misjudgment in the counting process.

[0050] In the embodiment of the present application, the detection system is surrounded by a shell to reduce the interference of external stray light on the sensor signal, and a filter is added to the sensor imaging system to further improve the quality of the collected light strip signal.

[0051] Figure 1 The schematic diagram of the non-contact rapid banknote counting method provided by the embodiment of the present application is shown.

[0052] As shown in Figure 1 , at step S110, the laser light strip image of the line laser light source irradiated on the edge of the measured banknote is collected.

[0053] In the embodiment of the present application, the method further comprises: a set of line laser light sources and sensors are arranged around each detection position, and the laser line emitted by each set of line laser light sources is orthogonal to the edge of the banknote in the detection position.

[0054] More specifically, during detection, the position of the banknote is kept fixed, and the line laser sensors located around the banknote respectively take a light strip image projected on the edge of the banknote. The pixel coordinates of each point in the image are represented by (u, v), where the horizontal coordinate u represents the column number of the point in the image, and the vertical coordinate v represents the row number of the point in the image.

[0055] More specifically, next turn to step S120.

[0056] At step S120, the laser light strip image is binarized to obtain a binarized image.

[0057] In the embodiment of the present application, the binarization processing of the laser light strip image comprises: setting the pixel points with pixel values greater than or equal to a preset value in the laser light strip image as bright points; and setting the pixel points with pixel values less than the preset value in the laser light strip image as dark points.

[0058] More specifically, a threshold t is set and the image taken by the sensor is binarized. The pixel points with pixel values greater than or equal to t in the image are set as bright points, and the pixel points with pixel values less than t in the image are set as dark points, then only the points on the light strip in the processed binarized image are bright points, as shown in Figure 2 .

[0059] Next turn to step S130.

[0060] At step S130, the coordinate points meeting the preset requirement in the binary image are screened.

[0061] In the embodiment of the present application, the screening of the coordinate points meeting the preset requirement in the binary image comprises: setting an image interval H, marking the pixel points with a vertical coordinate less than H among all the pixel coordinates in the binary image; recording the coordinates of the brightest point with the smallest vertical coordinate in each column of pixel points in the binary image, denoted as (u i ,v i ), wherein u i represents the column number, and v i represents the point with the smallest vertical coordinate among the brightest points in the u i th column; when there is no brightest point in the column of pixel points, the coordinate (u i ,H) is recorded.

[0062] More specifically, the image interval H is set, and the pixel points with v≤H among all the pixel coordinates in the binary image are found, wherein H represents the position of a row in the image, and when H is set, it is necessary to ensure that the vertical coordinate of the light bar signal pixel point is greater than H and is appropriately close. The coordinates (u i ,v i ) of the brightest point with the smallest pixel coordinate v in each column of pixel points are calculated and recorded, and if there is no brightest point in the column of pixel points, the coordinate (u i ,H) is recorded.

[0063] Next, go to step S140.

[0064] At step S140, one-dimensional signal peak detection is performed on the coordinate points meeting the preset requirement, and the number of banknotes is obtained.

[0065] More specifically, one-dimensional signal peak detection is performed on all the recorded pixel point coordinates in the image, and the number of peaks obtained is the number of banknotes obtained through the image, as shown in Figure 3 .

[0066] In the embodiment of the present application, the method further comprises: simultaneously measuring the banknote by the line laser light sources and sensors around the detection position to obtain a measurement result; causing a small range of pose change of the banknote in the detection position, and again measuring the banknote by the line laser light sources and sensors around the detection position until a preset number of measurement results are obtained; and taking the mode of the preset number of measurement results as the number of banknotes.

[0067] More specifically, the number of banknotes detected by the sensor in one time can be obtained by solving the photographed image through the above process. In order to ensure the reliability of the detection result, the measurement is carried out by the sensors located around the banknote at the same time during the detection, and then the banknote is changed in a small range of pose at the original position by the movement mechanism and measured k times to obtain a series of measurement results N of the number of banknotes i,j wherein is represents the result measured by the is sensor (is = 1, 2, 3, 4), j represents the measurement times (j = 1, 2, 3…k). The mode of the series of measurement results is the number of banknotes measured by the detection system.

[0068] In the embodiment of the present application, the laser stripe image is collected through the optical filter.

[0070] The acquisition module 410 is used for acquiring the laser stripe image of the laser light source irradiated on the edge of the banknote to be measured;

[0071] The binarization module 420 is used for carrying out binarization processing on the laser stripe image to obtain a binarization image;

[0072] The screening module 430 is used for screening the coordinate points meeting the preset requirements in the binarization image;

[0073] The detection module 440 is used for carrying out one-dimensional signal peak value detection on the coordinate points meeting the preset requirements to obtain the number of banknotes.
