Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1a is a flowchart of a bill stamping method according to an embodiment of the present invention, where this embodiment is applicable to a case of stamping a bill in a print control management system, and the method may be executed by a bill stamping device, where the device may be implemented in a software and/or hardware manner, and the device may be integrated in a print control device, as shown in fig. 1a, where the method specifically includes:

and 110, acquiring an infrared bill image of a bill to be stamped through infrared light photographing.

Wherein, the printing font of the common bill during publishing adopts infrared anti-counterfeiting ink to perform anti-counterfeiting printing. The infrared anti-counterfeiting ink is prepared by adding one or more near-infrared absorbing materials into the ink, and absorbs in a near-infrared region. For example, the infrared light can transmit 75% to 95% of the near infrared light, and the infrared light having a wavelength of 700 nm to 1000 nm can be absorbed. The oscillation wavelength falls in the near infrared region. When the infrared light is used for photographing the bill, the infrared anti-counterfeiting ink on the bill can absorb the infrared light, so that part of information on the bill can be in a hidden state, namely, an invisible state.

FIG. 1b is a schematic view of an infrared document image of a non-copy original document according to an embodiment of the present invention. As shown in fig. 1b, the print font (data information with a dotted line frame in fig. 1 b) of the ticket at the time of publication is photographed by infrared light, and then the ticket is in a transparent state. The printed font (data information not outlined in dashed lines in fig. 1 b) appears invisible. And the characters printed, copied or written in the bill at the later stage are in a visible state due to the adoption of the non-infrared anti-counterfeiting ink. The content in the infrared bill image can be greatly reduced, and the infrared bill image can be favorably subjected to subsequent processing, such as identification of an identification code in a bill to be stamped.

And 120, preprocessing the infrared bill image, performing OCR recognition on the preprocessed infrared bill image, and acquiring a recognition code obtained by recognition.

The infrared bill image preprocessing method comprises the following steps of preprocessing an infrared bill image, wherein the preprocessing of the infrared bill image can be to intercept an identification code area in the infrared bill image and preprocess the intercepted identification code area; alternatively, it may be a pre-processing of the entire infrared ticket image. Preprocessing may include removing color-contributing factors, crease-contributing factors, or other noise-contributing factors of the infrared ticket image.

Optical Character Recognition (OCR) refers to a process in which an electronic device examines a printed Character on a document, determines its shape by detecting dark and light patterns, and then translates the shape into computer text using Character Recognition methods. The electronic device may be a scanner or a digital camera, among others. The method can convert characters in the infrared bill image into image files of black and white dot matrixes, and convert the image files into text formats through recognition software for the word processing software to edit and process so as to generate computer characters.

Characters in the preprocessed infrared bill image are recognized through OCR, and the recognition code in the infrared bill image can be accurately acquired. The method can avoid directly carrying out OCR recognition on the original bill to be stamped, and has a large amount of background character interference. The recognition efficiency and the recognition accuracy can be improved.

In an implementation manner of the embodiment of the present invention, optionally, the preprocessing the infrared bill image includes: converting the infrared bill image into a gray image, and carrying out fuzzy processing on the gray image to remove noise; and carrying out binarization processing on the gray level image after the fuzzy processing to obtain a preprocessed infrared bill image.

Wherein the gray scale image may be obtained by measuring the brightness of each pixel within a single electromagnetic wave frequency, such as visible light, for the infrared bill image. The processing can be directly carried out through some image editing software, and the processing can also be realized through script programming. The blurring process may be a process of reducing noise by linear filtering. The average value blurring process, gaussian blurring process, median filtering, bilateral filtering, or the like may be used. The binarization is to divide the gray image subjected to the fuzzy processing into a foreground and a background, define the foreground information as black, and define the background information as white. The character information of the infrared bill image can be reduced, and the identification accuracy of the identification code in the infrared bill image is improved.

Fig. 1c is a schematic diagram of a preprocessed infrared bill image of a non-copy original bill according to an embodiment of the present invention, and as shown in fig. 1c, only some characters printed with non-infrared anti-counterfeit ink or some handwritten characters exist in the preprocessed infrared bill image of the non-copy original bill, so that accuracy of identification code recognition can be greatly improved.

Fig. 1d is a schematic diagram of a preprocessed infrared bill image of a copied original bill according to an embodiment of the present invention, and as shown in fig. 1d, a large amount of data information exists in the preprocessed infrared bill image of the copied original bill. If the original non-copied bill is pre-processed after being photographed by natural light, an image similar to that of fig. 1d can also be obtained. For the image shown in FIG. 1d, OCR recognition is likely to be affected by surrounding data information, resulting in inaccurate recognition.

And step 130, if the identification code is determined to be consistent with the expected code in the printing control management system, acquiring a white-light bill image of the bill to be stamped through natural light shooting.

The identification code may be information representing a bill to be stamped. Such as the number, serial number, authentication code, name or serial number of the ticket to be sealed. The operating system for realizing the bill stamping by the print control management system can be a hardware and/or software system. The expected code may be representation information corresponding to a bill which is expected to be subjected to a stamping operation in the printing control management system, for example, a serial number of the bill.

For example, before the bill is stamped, the bank staff may review the stamping request according to the stamping request, and record the representation information corresponding to the bill passing the request in the print control management system to generate the request message. The corresponding presentation information of the ticket may be an expected code in the request message. When the seal control management system carries out the seal operation, the request message can be obtained through the appointed path so as to obtain the expected code in the request message.

If the identification code is consistent with the expected code in the printing control management system, the bill to be stamped is shown to be the bill passing the stamping request, and the bill to be stamped can be photographed, so that a worker can monitor the stamped bill, check the work and the like. In order to make the obtained bill image clear and facilitate the checking work of the staff, the bill to be stamped can be shot by adopting natural light.

And 140, performing bill stamping on the bill to be stamped, and storing the white light bill image.

If the identification code is consistent with the expected code in the printing control management system, the bill to be stamped is the bill passing the stamping request, and the stamping operation can be carried out. The white light bill image obtained by photographing can be stored in the printing control management system, so that the staff can monitor the stamped bill for checking work and the like. When the bill seal verification device is used for storing, the identification code and the white light bill image can be stored correspondingly, and whether the seal of the bill is correct or not can be quickly verified by workers.

Fig. 1e is a schematic diagram of a white light bill image according to an embodiment of the present invention. As shown in FIG. 1e, all information in the white light bill image can be clearly identified, and reliable data dependence is provided for the subsequent checking work of staff.

In an implementation manner of the embodiment of the present invention, optionally, the performing bill stamping on the bill to be stamped includes: acquiring stamping configuration information matched with at least one type of bill from pre-stored bill configuration information; extracting a sealing position and a sealing rotation angle matched with the bill to be sealed from the sealing configuration information according to the type of the bill to be sealed; and after the signature is controlled to rotate along the reference angle by the signature rotation angle, the bill to be stamped is stamped at the stamping position of the bill to be stamped.

Wherein, in the print control management system, bill configuration information of different types of bills is stored in advance. For example, the request message may record ticket configuration information of different types of tickets. The ticket configuration information may include a ticket type and ticket information corresponding to the ticket type. The bill information may be the size of the bill, the position of the seal, the rotation angle of the signature, the position of the identification code, and the like.

The note types may be liquidated notes and non-liquidated notes. The non-liquidation bill can be further divided according to the actual business requirement, such as settlement, liquidation, reconciliation and the like. The stamping position may be a position of the signature in the ticket, and may be, for example, an origin point of a central position of the signature in the print control management system, and the stamping position may be an abscissa and an ordinate with respect to the origin point. The signature rotation angle may be an angle, for example, 0 degrees, by which a reference angle with respect to the signature needs to be rotated when the desired signature is stamped in the document. The seal position in the bill can be enabled to be correct, and the seal information can be observed conveniently. After the stamping is finished, the signature is rotated back to the original reference angle.

According to the technical scheme of the embodiment, an infrared bill image of a bill to be stamped is obtained through infrared light photographing; preprocessing the infrared bill image, and performing OCR recognition on the preprocessed infrared bill image to acquire a recognition code obtained by recognition; if the identification code is determined to be consistent with the expected code in the printing control management system, acquiring a white-light bill image of the bill to be stamped through natural light shooting; the bill stamping is carried out on the bill to be stamped, and the white light bill image is stored, so that the problem of bill stamping in the printing control management system is solved, and the effects of high recognition accuracy rate and high stamping accuracy rate of the bill identification code are achieved.

Example two

Fig. 2a is a flowchart of a note stamping method provided in a second embodiment of the present invention, which is a further refinement of the above technical solution, and the technical solution in this embodiment may be combined with various alternatives in one or more of the above embodiments. As shown in fig. 2a, the method specifically includes:

and step 210, acquiring an infrared bill image of a bill to be stamped through infrared light photographing.

And step 220, intercepting at least one infrared ink anti-counterfeiting area in the infrared bill image.

The infrared ink anti-counterfeiting area refers to an area which should be printed by adopting infrared anti-counterfeiting ink in the bill. And the area printed by adopting the infrared anti-counterfeiting ink in the infrared bill image is in an invisible state. When the infrared ink anti-counterfeiting area is intercepted, the infrared ink anti-counterfeiting area which cannot be changed by manpower can be intercepted. For example, a name area of a bill or a bill header information area, etc.

And step 230, if the copying characteristic data is not identified in each infrared ink anti-counterfeiting area, determining that the infrared bill image is a non-copying original bill.

Wherein, the area printed by adopting the infrared anti-counterfeiting ink in the infrared bill image is in an invisible state. Therefore, when the copy characteristic data is not recognized in the infrared ink anti-counterfeiting area in the infrared bill image, the infrared ink anti-counterfeiting area of the bill is printed by using the infrared anti-counterfeiting ink, and the bill is a non-copy original bill and can be understood as a true bill. And if the copying characteristic data is identified in the infrared ink anti-counterfeiting area, the infrared ink anti-counterfeiting area is printed without adopting infrared anti-counterfeiting ink, and the original bill is copied and can be understood as a false bill.

Fig. 2b is a schematic diagram of an infrared bill image of a copied original bill according to the second embodiment of the present invention. As shown in fig. 2b, the data in the infrared bill image of the original copy bill are all in a visible state, and when any infrared ink anti-counterfeiting area is intercepted for copy characteristic data identification, the copy characteristic data can be identified. It can be determined to copy the original ticket. The stamping operation can not be executed for the original bill of copy, and the stamping accuracy can be improved.

And step 240, if the infrared bill image is determined to be the non-copy original bill, converting the infrared bill image into a gray image, and performing fuzzy processing on the gray image to remove noise.

And step 250, carrying out binarization processing on the blurred gray level image to obtain a preprocessed infrared bill image.

In order to further improve the accuracy of OCR recognition, the type of the bill to be stamped can be recognized by using a template matching method. And extracting the stamping configuration information corresponding to the type of the bill to be stamped from the pre-stored bill configuration information. And extracting the verification code position and the serial number position matched with the bill to be stamped from the stamping configuration information. The verification code position and the number position may be position data expressed by an abscissa and an ordinate with a signature position as an origin in the print control management system.

For example, the validation code location may record the abscissa of the start location, the abscissa of the end location, the ordinate of the start location, and the ordinate of the end location of the validation code in the ticket with respect to the origin.

The intercepted area may be an area that is consistent with the position of the authentication code and the numbering position, or may be an area that is consistent with the position of the authentication code and the numbering position and is added with a certain error area. The accuracy of OCR recognition can be improved, and OCR recognition errors caused by interception offset can be avoided.

And 270, if the identification code is consistent with the expected code in the printing control management system, acquiring a white light bill image of the bill to be stamped through natural light shooting, and storing the white light bill image.

And step 280, acquiring stamping configuration information matched with at least one type of bill from the pre-stored bill configuration information.

And 290, extracting the sealing position and the sealing rotation angle matched with the bill to be sealed from the sealing configuration information according to the type of the bill to be sealed.

Step 2100, after controlling the signature to rotate the signature rotation angle along the reference angle, performing bill sealing on the bill to be sealed at the sealing position of the bill to be sealed.

Step 2110, acquiring a stamped white light image of the bill to be stamped through natural light shooting, and storing the stamped white light image of the bill to be stamped.

The method and the device have the advantages that the stamped bill image is obtained, so that the staff can conveniently compare, check and the like bills before and after stamping. In order to clearly record the seal condition of the bill, such as identifying the type of the seal, the sealed bill can be shot by using natural light, a sealed white light image is obtained, and the white light image is stored in the printing control management system.

According to the technical scheme of the embodiment, an infrared bill image of a bill to be stamped is obtained through infrared light photographing; intercepting at least one infrared ink anti-counterfeiting area in the infrared bill image; if the copying characteristic data are not recognized in each infrared ink anti-counterfeiting area, determining that the infrared bill image is a non-copying original bill; if the infrared bill image is determined to be the non-copy original bill, converting the infrared bill image into a gray image, and carrying out fuzzy processing on the gray image to remove noise; carrying out binarization processing on the gray level image after the fuzzy processing to obtain a preprocessed infrared bill image; performing OCR recognition on the preprocessed infrared bill image to obtain a recognition code obtained by recognition; if the identification code is consistent with the expected code in the printing control management system, acquiring a white light bill image of the bill to be stamped through natural light shooting, and storing the white light bill image; acquiring stamping configuration information matched with at least one type of bill from pre-stored bill configuration information; extracting a sealing position and a sealing rotation angle matched with the bill to be sealed from the sealing configuration information according to the type of the bill to be sealed; after controlling the signature to rotate along the reference angle by the signature rotation angle, performing bill stamping on the bill to be stamped at the stamping position of the bill to be stamped; the white light image after stamping of the bill to be stamped is obtained through natural light shooting, and the white light image after stamping of the bill to be stamped is stored, so that the problem of stamping of the bill in a printing control management system is solved, the recognition accuracy rate of the bill recognition code is high, the stamping accuracy rate is high, the stored bill is clear and easy to recognize, and the checking effect is convenient.
