Description

  The present invention relates to an OCR (Optical Character Reader, hereinafter referred to as “OCR”) reading result automatic correction system for an order card. For details, the OCR reading result of the order card for the purpose of automatically correcting misreading in the OCR reading result of the product code of the handwritten form entered on the order card and making the reading of the OCR filling sheet more labor-saving and accurate. It relates to the correction system.

  The OCR is a device that optically reads a handwritten character or a printed character, specifies a character by collating with a previously stored pattern, and inputs character data.

  In catalog sales by mail order etc., various products such as clothes, cosmetics, foods, etc. appearing in the catalog are numbered with product codes, and this product code is placed on an order card and ordered. .

  The manufacturer that received the order reads the product code written on the order card with the OCR, identifies the code (number) by matching it with the pattern stored in advance, and selects the product that matches the product code with a computer. (See, for example, Patent Document 1).

  However, although OCR is a character recognition device that optically reads handwritten characters, there is a problem that a high recognition rate cannot be expected at present due to irregular character writing due to character wrinkles due to individual differences associated with handwriting.

  Therefore, in the OCR automatic reading of the product code of the order card, a reading error of about 5% occurs. This reading error can be corrected by visually checking the image by outputting an image from the OCR reading result. There is a problem that it is necessary to perform a visual check again before the correction is made, and that labor saving cannot be realized for the purpose of using the OCR.

  The present invention was devised in view of the above points, and automatically corrects misreading that occurs in an OCR reading result, thereby making the reading result of an OCR entry sheet more accurate. The purpose is to provide.

  In order to achieve the above object, an order card OCR reading result automatic correction system according to the present invention automatically corrects misreading that occurs in the reading result of a product code written on an OCR sheet by OCR. In the automatic correction system, means for storing a product master code related to an entry of an OCR sheet of the company in a database, data read by OCR by an automatic correction program, and a product master code stored in the database Automatic correction means that automatically checks and corrects the error and saves it as regular data, and outputs the error data that could not be compared with the product master code by the automatic correction program as an image on the dedicated screen for manual correction Manual correction means to perform.

  Here, the data after OCR reading is collated with the product master code related to the OCR sheet entry of the company by the automatic correction program, the error is automatically corrected, the error data is distributed to the recognized product data, It is possible to reduce manual correction by visual observation by outputting error data as an image on a dedicated screen and performing manual correction.

  In addition, the data after OCR reading is collated with the product master code including prime numbers related to the entry items of the company's OCR sheet by the automatic correction program, the error is automatically corrected, and the error data is distributed to the recognized product data. Therefore, automatic correction with high accuracy becomes possible.

  In the present invention, a prime number is a natural number larger than 1 that has no positive divisor other than 1 and the number itself (that is, cannot be divided by 1 or any natural number other than the number).

  According to the present invention, data after OCR reading is output to a text file and an image file, collated with a prime code using a database, and classified as “unreadable”, “misread”, and “no error”. If there is no error, the process automatically proceeds to the next process, and the program that saves it as regular data and the data that is considered “unreadable” and “misread” are manually corrected on the screen dedicated to the output image. Therefore, the human visual check can be minimized, and the reading time can be made more efficient and the cost can be reduced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings to provide an understanding of the present invention.
FIG. 1 is a system conceptual diagram for explaining an embodiment of an order card OCR reading result automatic correction system (hereinafter referred to as “the present system”) to which the present invention is applied.

  In this system shown here, an OCR sheet 1 in which a product master code including a prime number is entered, an OCR device 2 for reading the product master code entered in the OCR sheet 1, and a master code including a prime number are stored. A database 3, an error database 4 in which a master code that could not be read by the OCR device 2 is stored, and an automatic verification correction program 5 that automatically corrects the data obtained by the OCR device 2 to the stored master code , An authenticated product master code database 6 in which product master codes recognized by the OCR device 2 and the automatic verification correction program 5 are stored, and an error in which product master codes that could not be verified by the automatic verification correction program 5 are stored Check the database 4 and the product master code stored in the error database 4. Against by a visual confirmation data output device 7 for correcting and is formed from a read result storage database 8.

Next, the operation process of the OCR reading result automatic correction system for the order card will be described in detail.
First, as shown in FIG. 2, for example, as shown in FIG. 2, the OCR sheet 1 is printed with an address, name and telephone number entry field, a 5-digit order code, and a quantity and amount field. In the order code column, the five-digit order number assigned to the product to be ordered is entered. In the quantity column, the quantity of the product to be ordered and the price column are entered by multiplying the unit price and the quantity of the product. The

  Therefore, as shown in FIG. 1, the five-digit product code written on the OCR sheet 1 is optically read by the OCR device 2 and the product code is identified by matching with a pre-stored pattern. It is input to the recognized product master code database 6. The product code data that could not be read by the OCR device 2 is stored in the error database 4.

  Then, the product codes entered in each OCR sheet 1 stored in the recognized product master code database 6 and the error database 4 are stored in the database 3 in which the master code including prime numbers is stored by the automatic verification correction program 5. The product code is collated, the corresponding product code is selected, and the product code is corrected.

The product data recognized by the automatic verification correction program 5 is input to the authenticated product master code database 6 and stored in the read result storage database 8.
Further, the product code data that could not be recognized by the automatic verification correction program 5 is stored in the error database 4, displayed as an image by the visual confirmation data output device 7, corrected by the operator visually, and corrected product data. Is stored in the result storage database 8.

Here, an example of this system by the automatic collation correction program 5 will be described with reference to the block diagrams of FIGS.
First, as shown in FIG. 3, when the first character of the 5-digit product code that could not be read by the OCR device could not be read, the codes other than the first character match from the database that stores the master code including prime numbers. Select the number of product codes to be used.

  For example, if there is only one matching product code, the product code is authenticated, corrected to the product code, and input to the authenticated product master code database 6. If the matching product code is 0, or 2 or more, the product code cannot be specified, and an error process is performed.

  Next, if the second character of the 5-digit product code that could not be read by the OCR device could not be read, the product code that matches the code other than the second character from the database storing the master code including prime numbers Select how many types.

  For example, if there is one matching product code, the product code is recognized, is corrected to the product code, and is input to the recognized product master code database 6. If the matching product code is 0, or 2 or more, the product code cannot be specified, and an error process is performed.

  If the third, fourth, or fifth character of the 5-digit product code that could not be read by the OCR device is not readable, the product matches the code from the database that stores the master code including prime numbers. If there is one matching product code, it is recognized that it is the product code. If the matching product code is 0, or 2 or more, the product code is selected. Error handling because it cannot be identified.

  Next, as shown in FIG. 4, an example of a recognition system in the case where the 4-digit product code normally read by the OCR device does not match the product code from the database in which the master code including the prime number is stored. Describe.

  First, it is checked whether or not the first digit is misread. Extraction is made from a database in which a master code having a prime number that matches three digits other than the first digit is stored. Then, a product that matches the unit price of several types of extracted product codes is selected, and if there is only one product that matches the unit price, the product code is corrected and input to the authenticated product master code database.

  If there are two or more items with a matching unit price, the product code cannot be specified, and an error process is performed. If there are zero items with a matching unit price, the process proceeds to the next stage. Check if the second digit is misread. Extraction is performed from a database in which a master code having a prime number that matches three digits other than the second digit is stored.

  Therefore, a product with a matching unit price is extracted from the several types of product codes extracted. If there is only one unit with a matching unit price, the product code is corrected and entered into the certified product master code database. If there are two or more items with a matching unit price, the product code is specified. Error handling because it is not possible.

  If the unit price matches zero, the process proceeds to the next stage. Check if the third digit is misread. The same processing as described above is performed, and when checking whether the fourth digit is erroneously read as the final step, the master code having a prime number that matches the three digits other than the fourth digit is extracted from the database.

  Therefore, a product with a matching unit price is extracted from the several types of product codes extracted. If the unit price matches one, the product code is corrected and entered into the authenticated product master code database. If the unit price matches is two or more, or zero , Error handling because the product code cannot be specified.

  When the product code is specified as described above, the product code is corrected and input to the authenticated product master code database. When an error process is performed, the product code is returned to the error database. As described above, the data is displayed on the screen by the data output device 7 for visual confirmation, the product code is visually corrected, and the result is input to the authenticated product master code database. The storage database 8 can be stored accurately and quickly.

It is a system conceptual diagram for demonstrating one Example of the OCR reading result automatic correction system of the order card to which this invention is applied. It is explanatory drawing which shows an example of the order card to which this invention is applied. It is block explanatory drawing which shows the process until it specifies the goods code of this system to which this invention is applied.
