  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 is a block diagram showing a configuration of an arrangement stamping machine 1 according to an embodiment of the present invention. The assortment stamping machine 1 detects the fee stamp attached to the paper sheets supplied by the operator, aligns the front and back of the paper sheets, and stamps them on the fee stamp. It is to be classified.

  In the following description, the surface of the paper sheet to which the fee stamp is assigned is the front surface of the paper sheet, and the opposite surface is the back surface of the paper sheet.

  As shown in FIG. 1, the arrangement stamping machine 1 includes a supply unit 11, an image input unit 12, a fee stamp detection unit 13, a control unit 14, a reversing unit 15, a stamping unit 16, and a sorting unit 17. Has been.

  Between each part of this arrangement stamping machine 1, it is comprised so that paper sheets may be conveyed through the conveyance path which does not show illustration.

  The supply unit 11 is configured to supply paper sheets to the assortment stamping machine by an operator. At this time, the operator supplies the sheets to the supply unit 11 without aligning the front and back of the paper sheets. The supply unit 11 takes out the supplied sheets one by one and supplies the sheets to a conveyance path (not shown).

  The image input unit 12 is configured to read the front and back surfaces of a paper sheet conveyed from the supply unit 11 via a conveyance path (not shown). For example, the image input unit 12 includes a scanner that optically reads an image on the front side of a conveyed paper sheet and a scanner that optically reads an image on the back side of the paper sheet.

  The fee stamp detection unit 13 performs a fee stamp detection process on the two images on the front and back surfaces of the paper sheet conveyed from the image input unit 12 via a conveyance path (not shown). For example, the fee stamp detection unit 13 detects information indicating whether or not the fee stamp has been detected, information indicating the surface on which the fee stamp has been detected, information indicating the position of the detected fee stamp, and the like. The processing result is supplied to the control unit 14.

  The control unit 14 indicates a CPU (Central Processing Unit), performs a type of fee stamp determination processing, a fee stamp recognition processing, and the like based on the detection processing result of the fee stamp detection unit 13, and paper sheets Determine the processing for For example, the control unit 14 performs processing in the later-described stamping unit 16 in the current transport state based on information indicating the surface where the fee stamp is detected and information indicating the position where the fee stamp is detected. Judge whether or not is possible. If it is determined that the paper sheet can be stamped by this determination, the control unit 14 does not reverse the paper sheet by the reversing unit 15 described later, but through the conveyance path (not shown) in the current conveyance state. The conveyance control to the stamping unit 16 is performed. On the other hand, if it is determined that the paper sheet cannot be stamped in the current transport state, the control unit transfers the paper sheet to the stamp unit 16 in the reversing unit 15 described later via a transport path (not shown). Control to transport. The control unit 14 has a fee stamp recognition unit 18 for recognizing and processing the fee stamps detected from the paper sheets.

  The fee stamp recognition unit 18 performs pattern recognition processing of the detected fee stamp and the pattern of the fee stamp stored in the stamp dictionary 19 described later, thereby determining the type of the fee stamp and the fee stamp face. recognize. Based on the recognition result of the fee stamp by the fee stamp recognition unit 18, the control unit 14 determines the type of the paper sheet described above.

  The reversing unit 15 transports the paper sheets, whose images on the front and back surfaces of the paper sheets have been read by the image input unit 15, through the transport path, and aligns the orientations of the paper sheets based on the control by the control unit 14. Inversion processing is performed. For example, the control unit 14 determines whether or not it is necessary to reverse the paper sheet while the paper sheet is conveyed from the image input unit 12 to the reversing unit 15. Based on this determination, the reversing unit 15 executes a determination process for the paper sheet according to the control of the control unit 14. That is, the reversing unit 15 conveys the paper sheet to the stamping unit 16 in a state in which the fee stamp can be stamped according to control by the control unit 14.

  The stamping unit 16 performs a stamping process on the paper sheet conveyed from the reversing unit 15 via the conveyance path based on information indicating the position of the fee stamp supplied from the control unit 14.

  The sorting unit 17 is provided with a plurality of stacking units (sorting ports) (not shown), and the paper sheets subjected to the stamping process in the stamping unit 16 are transported through the transport path and supplied from the control unit. Sort paper sheets by type.

  FIG. 2 is a schematic diagram showing a flow of data processing at the time of creating the stamp full-face dictionary 25 and the stamp fee dictionary 26. The paper sheet image data 21 is a paper sheet image read by the image input unit 12 of the assortment stamping machine 1. The image of the paper sheet is sent to a PC (Personal Computer) 80 as shown in FIG.

  The stamp registration program 22 is a program executed by the PC 80, and has a simulator 23 having a function of detecting a stamp position from paper sheets and recognizing the stamp from the detected stamp position.

  The simulator 23 creates a stamp dictionary 19 (a postage stamp full dictionary 25 and a stamp fee dictionary 26 described later) using the algorithms of the fee stamp detection unit 13 and the fee stamp recognition unit 18.

  The stamp registration program 22 reads the paper sheet image data 21, detects the stamp position of the simulator 23, and displays the result on the screen. The operator selects one of the displayed stamp detection results determined to be suitable for registration in the stamp dictionary.

  Based on the stamp detection result selected by the operator, the stamp registration program 22 creates a stamp similarity dictionary and registers it in the stamp database 24 as a stamp full-face dictionary 25.

  At the same time, the operator uses the input function of the PC 80 to input stamp information (stamp ID, stamp size, afterglow information). The input stamp information is registered in the stamp database 24 as a stamp information table 27.

  Also, if the stamps to be registered have the same pattern and differ only in the fee (hereinafter, this stamp is referred to as the same pattern stamp), the operator creates the stamp full-face dictionary 25 from the respective stamp images, and at the same time, the operator A dictionary for the designated fee portion is created separately and registered in the stamp database 24 as a stamp fee dictionary 26.

  FIG. 3 is a flowchart of a stamp dictionary creation process using the stamp registration program 22 by the operator. The stamp dictionary creation process will be described below with reference to FIG.

  The operator attaches the stamp to be registered to the paper sheet (S1). The paper sheets with the stamps to be registered are supplied to the complete stamping machine 1. The supplied paper sheet is conveyed by the conveyance path, and the image on the sheet surface is read by the image input unit 12 (S2). This process (S1, S2) is performed on all the stamps to be registered.

  Further, in the case of a non-rectangular stamp, the same stamp is attached to a plurality of paper sheets (brown envelope, white envelope, etc.) having different ground colors, and the image is read in the same manner as described above.

  The operator operates the PC 80 to activate the stamp registration program 22 (S3). The stamp registration program 22 reads the image of the paper sheet read in S2, executes a stamp detection process using the simulator 23, and displays it on the screen of the PC 80 (S4).

  The operator checks whether or not there is a suitable one for registration in the stamp dictionary from the displayed stamp detection results (S5). If there is a stamp suitable for registration in the stamp dictionary among the detection candidates displayed on the PC 80 (Yes in S5), the operator selects it and stores it in the storage unit of the PC 80 (S6).

  On the other hand, when there is no suitable stamp (when there is no detection candidate, or there is no stamp suitable for registration in the stamp dictionary among the detection candidates) (No in S5), the operator designates the area and again It is determined whether or not to perform detection processing (S7).

  When performing re-detection (Yes in S7), the simulator 23 performs re-detection in the designated area by designating an approximate area including the stamp (S8). The result of the re-detection process is displayed on the screen of the PC 80, and the process returns to S5.

  When there is no suitable stamp in this way, an operator can specify an area and perform detection processing again, so that an accurate stamp candidate position can be detected without being affected by advertisements or addresses.

  Further, without using the detection result of the simulator 23, the operator can manually cut out the area and save it in the storage unit (S9).

  Based on the images stored in S6 and S9, the full-face stamp dictionary 25 is created (S10). At this time, the operator inputs stamp information such as a stamp ID, afterglow information, and a charge of the stamp image, and inputs the stamp information input here and information such as a stamp size calculated at the time of detection in S4. Saved in the stamp information table 27. An example of the stamp information table 27 is shown in FIG. Further, in the case of non-rectangular stamps, the processing from S4 to S9 is performed for the number of sheets attached. At this time, the stamp ID stored in the stamp information table 27 designates the same number. That is, when the same number is designated as the stamp ID, the stamp registration program 22 can be stored and managed as separate image files by sequentially assigning serial numbers to the stamp image files.

  After S10, the stamp registration program 22 determines whether the stamp pattern to be registered is the same pattern stamp as the dictionary pattern registered in advance in the stamp full-face dictionary 25 (S11). As a result of the determination in S11, if the images are the same pattern stamp image, the operator creates the stamp fee dictionary 26 by selecting the area in which the fee is described in the stamp image (S12). The stamp fee dictionary 26 may be stored as a simple image file. At this time, different numbers are designated as stamp IDs of the same pattern stamp image as shown in FIG. Then, the stamp ID of the stamp image having the same pattern as the stamp image is designated and stored in the stamp information table 27 as the stamp ID of the same pattern stamp image. At the time of recognition of the stamp image, matching with the stamp fee dictionary 26 is performed only for the stamp image in which the IDs of the same pattern stamps are registered. The stamp information table 27 simultaneously stores the fee value specified by the operator and the fee coordinate information calculated by the stamp registration program 22 when the fee region is specified.

  A recognition experiment is performed using the full-face stamp dictionary 25 created in S10 and the stamp fee dictionary 26 created in S12 (when the same pattern stamp exists) (S13).

  The recognition experiment in S13 is performed by the simulator 23 included in the stamp registration program 22 as follows. The stamp pattern registered in the full stamp dictionary 25 is collated with all the dictionary patterns registered in advance in the full stamp dictionary 25, and the respective similarities are calculated.

  Among them, the stamp ID of the dictionary pattern having the maximum similarity is set as the recognition result for the stamp pattern.

  When the stamp ID of the same pattern stamp is registered in this recognition result, the charge cannot be determined only with the pattern of the stamp.

  That is, when the stamp pattern having the maximum similarity is output as ID = 1 in the stamp information table 27, the same pattern stamp for ID = 1 is not registered (the same pattern stamp in the first line of the stamp information table 27). Since the postage stamp ID field is blank), the recognition result is confirmed as (stamp ID = 1, fee = 53).

  On the other hand, if the stamp ID of the same pattern stamp is registered in the recognition result, the charge determination cannot be performed only with the stamp pattern as described above, so matching with the stamp fee dictionary 26 is performed. A fee image is cut out from the stamp pattern based on the fee coordinates stored in the stamp information table 27, the extracted pattern and the fee dictionary registered in the stamp fee dictionary 26 (the ID registered in the stamp ID of the same pattern stamp) Matching). As a result, the one having the maximum similarity is determined as the charge recognition result. For example, in the stamp information table 27, when the dictionary pattern having the maximum similarity is output as ID = 20, the same pattern stamp for ID = 20 is registered, so matching with the fee dictionary is required.

  FIG. 5 is a diagram showing an outline of this processing. Stamps having the highest similarity among 11 types of the same pattern stamps (the stamp IDs 13 to 24 shown in FIG. 4) and the stamp fee dictionary 26 having the stamp ID 20 If the ID is 21, the final recognition result is determined as (stamp ID = 21, fee = 5). That is, the stamp ID = 20 of the stamp recognition result is rejected and the stamp ID = 21 is determined.

  After the recognition experiment in S13, the similarity of the recognition result obtained as described above is compared with a specified constant threshold value (S14). As a result of the comparison with the threshold value in S14, if the degree of similarity is higher than the threshold value (Yes in S14), the stamp full face dictionary 25 and the stamp fee dictionary 26 are registered correctly in the stamp database 24 (S15).

  On the other hand, as a result of comparison with the threshold value in S14, if the degree of similarity is less than or equal to the threshold value, the stamp pattern dictionary 25 and the stamp fee dictionary 26 created in S10 and S12 are deleted and the stamp pattern dictionary 26 is deleted and the process proceeds to S14. Return (No in S14).

  As described above, by installing a simulation function in the stamp registration program 22, a stamp dictionary is created by using a stamp recognition result obtained by the stamping stamp machine 1, so that an operator designates a stamp region and a stamp region. In addition to simplifying the stamp dictionary registration procedure compared to creating a stamp dictionary, the accuracy of the stamp database 24 including the created stamp dictionary is improved. Furthermore, since a stamp dictionary can be created from stamp images affixed to a plurality of paper sheets having different ground colors, the recognition performance of non-rectangular stamps is improved.

  Further, by creating the stamp full face dictionary 25 and the stamp fee dictionary 26, it is possible to identify stamps having the same symbol and different charges. That is, it is not necessary to use a color scanner or the like, and it is possible to calculate the stamp fee even when the stamp does not contain information such as an afterglow bar.

  Note that the present invention is not limited to the above-described embodiment, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments. For example, some constituent elements may be deleted from all the constituent elements shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
