Description

Optical mark reading processing method supporting marking recognition and image file conversion based on reference coordinate values{OMR information processing apparatus and method}

The present invention relates to an optical mark reading processing method that supports marking recognition based on reference coordinate values and image file conversion, and more specifically, scanning and converting it into an image file by scanning a reading card to perform storage and management. It is easy, and the reference coordinate value is set due to the individual recognition unit given to the reading card. It relates to a method for processing optical mark reading which supports marking recognition based on value and image file conversion.

Generally, an optical mark reader (hereinafter referred to as OMR) is a device that reads a specific symbol through an optical method and converts data contents into electrical signals through light and inputs it into a computer. The OMR is a structure for marking or writing on a separately provided OMR card with a black-based writing tool that is easy to read light. The reading system using the OMR is mainly used as a test answer sheet for students, and is also used in a wide variety of fields, such as registering for classes, processing grades, and reporting births.

While the OMR system has the advantage of being able to process a large amount of data quickly and easily, for a variety of reasons, such as when the individual recognition unit formed on the OMR card is slightly damaged or the marking is out of the recommended form or when the marking is not black There was a problem that could cause errors in reading.

Accordingly, companies related to OMR systems are in the process of developing efforts to solve the problems through hard work, and for example, Registration Utility Model Publication No. 20-0363369, "Examination aid for preventing OMR card misregistration," is published. The technology includes a body part in which one side is open and the OMR card is embedded, and a plurality of through parts formed at corresponding positions to identify the number display part and the correct answer display part of the OMR card, respectively located inside the through hole It is composed of a detection unit and a confirmation unit in which a predetermined color is expressed when a sign pen for examination is contacted with the detection unit.

The prior art actively prevents damage to the OMR card by shielding the area outside the marking, while the usability is significantly reduced due to the process of separately preparing the auxiliary tool and the process of installing the auxiliary tool, and mounting the auxiliary tool. If damage is made before the following, the problem of reading errors cannot be solved, and problems beyond the recommended form of marking cannot be solved.

On the other hand, as another example of the OMR system-related technology, there is published Patent Registration No. 10-1139765 "Method of Recognizing Marking of OMR Cards Using Image Patterns". This technology stores the image of multiple box compartments partitioned within the OMR card as a box pattern, stores line-by-line or individual detailed images as detailed patterns in the box compartment, and identifies various marking examples in the marking part where marking is performed. We propose a method of recognizing the marking through the pattern and contrast of the reference data by sequentially selecting the box pattern, detailed pattern, and discrimination pattern among the inspection target data scanned from the OMR card of the inspection target after forming the reference data by storing them as do.

The prior art can recognize markings outside the recommended form through patterns set in various conditions, but cannot solve the problem that the corresponding OMR card cannot be read when the area outside the marking or the individual recognition unit is damaged.

In addition to providing an OMR system capable of recognizing markings written in various forms while being able to read even if the individual recognition unit is damaged for the above reasons, as well as to manage hundreds or thousands of read-out read cards, the risk of loss is rich.

It consists of a time mark section 122.

For example, the standard mark unit 121 is mainly formed at each corner of the paper 110, and provides a standard coordinate value for the standard mark unit to check whether or not the paper is loaded and to detect the direction of the paper input, as well as a mark for reading. Designates the starting position of the sensor A and serves as a route guide to the time mark part 122. In particular, it recognizes the shape and color of the standard mark part through the mark sensor (A), stores the recognized information, and relies on the pen for reading marks by detecting all markings similar to the standard mark part in the reading card based on the stored information. It can be read even if it is marked with a regular ballpoint pen or pencil, away from the conventional method that had to be done.

The marking cell 130 is a space for writing a response to at least one of a plurality of options for a plurality of items, and the marking cell also serves to write information of the author in addition to the options for the item.

The time mark section 122 is formed in plural according to the vertical and horizontal arrangement of the marking cells 130 in the space between the standard mark sections 121, and the mark sensor A starting from the standard mark section enters along the arrangement of each marking cell. It serves to induce the author to grasp the location of the marking written by the author.

On the other hand, the optical mark reader is configured in a form similar to that of the multi-function device, an input unit for receiving a plurality of read cards; a scanning unit for scanning the input read card; and a marking cell 130 for detecting marking from the scanned cell It consists of a reading unit; a platform 240 for modifying reading conditions and exposing the scanned paper to the screen; and a storage unit for storing the read data and the scanned reading card in a form that can be read by a PC.

Here, the scan unit is divided into a real scan and a program scan, and the real scan scans the reading card 100 using light reflection in the same way as a general scan method, and converts the information generated through scanning into an image file to create a platform. (240).

On the other hand, in the program scan, a template having the same configuration as the read card 100 is programmed with Excel or the like and registered on the platform 240, and the marking information of the read card scanned from the scan unit is read and read based on the read information. It is a method of exposing a read card template file that can be modified and manipulated by a PC to the screen of the platform by applying it to a card template.

The platform 240 collectively manages the work process, such as setting the read operation position of the read card 100 to be input, setting the arrangement conditions of the marking cells 130 to be read, or pre-work to detect the marking of the read card. It provides that functionality.

The platform 240 of the present invention comprises a setting unit 241 for setting reading conditions of the reading card 100, and an exposure unit 242 for displaying a reading card converted into an image file or a reading card template on a screen. do.

The setting unit 241 sets the arrangement conditions of the marking cell 130 and then sets and manages the set data by category, and the marking management unit 241-1, and the human management unit 241- that manages the personal data of the author 2) once again classified.

The marking management unit 241-1 provides a marking cell 130 capable of selecting and marking an identification code for an item on one side of the paper 110, and allows an author to write an identification code for each item to read the card later ( When reading 100), the problem of mixing other reading items with a reading card written through an identification code is basically excluded.

In the optical mark reading processing method of the present invention having the above-described configuration, the reading processing proceeds as follows.

2 is a flowchart sequentially listing a method for processing optical mark reading supporting marking recognition and image file conversion based on reference coordinate values constructed according to a preferred embodiment of the present invention.

As shown in FIG. 2, the optical mark reading processing method of the present invention reads a plurality of reading cards 100 marked by a plurality of writers into the input unit 210 of the optical mark reader 200. Input step (S10); And, a read card scanning step (S20) for scanning the input read card to convert to an image file; And, through the mark sensor (A) entering from all directions to sequentially mark the marking cell 130 A reading card reading step (S30) for detecting; and a reading card processing step (S40) for comparing the read data with recommended data to derive a result; and storing the derived data and reading card in a file format that can be read by a PC It comprises a; data storage step (S50).

In the reading card input step (S10), when a plurality of reading cards are stacked in the input port 210 of the optical mark reader 200, the optical mark reader operates to sequentially input from the bottom of the read card 100 stacked in the input port. In particular, since an identification code is provided to distinguish the read card by item or author, it is possible to input the read card randomly without needing to separate and stack the read cards individually.

As described above, the read card scanning step (S20) provides a real scan method and a program scan method. Each method may use a scan method setting function provided on the platform 240 to adopt any method desired by the operator to proceed with the reading operation.

In addition, the real scan method provides various image formats such as jpg, tif, and pdf so that the format of the image file converted by scanning can be specified, and by using this, the operator sets the format in the real scan function of the platform 240 Through this, the desired image format can be set in advance.

In the reading card reading step (S30), a plurality of individual recognition units 120 formed on the reading card 100 provide a reference coordinate value to set a movement path of the mark sensor A to follow the set path of the reading card. This is the step of precisely reading and detecting all areas.

In the reading card reading step (S30), a reading position setting step (S31) of searching for reference coordinate values of the reading card (100) and a time mark searching step of searching for the time mark unit (122) of the reading card whose position has been corrected. It is composed of (S32), and a marking cell path search step (S33) to find and move the marking cell 130 through a time mark.

In the reading position setting step (S31), in case a situation in which the entry direction of the reading card 100 entered through the inlet of the optical mark reader deviates from the preset entry line and deviates from the start position of the mark sensor A The mark sensor (A) enters all directions of the reading card and serves to correct the position by minimizing the offset distance from the mark sensor (A). For example, the conventional mark sensor (A) was limited to reading one direction from right to left or left to right, so it was the placenta that the reading card outside the entry line could not be recognized. However, in the case of simultaneous reading from all directions of the reading card as in the present invention, when the reading is performed, the displaced separation distance is minimized, and the readability is actively improved, thereby primarily preventing errors in reading.

In addition, in the reading position setting step (S31), a plurality of mark sensors (A) entering from all directions of the reading card 100 accurately recognize the range in which reading in the reading card is to be performed, and thus, errors in reading are secondary. It serves to prevent.

In addition, the read position setting step (S31) detects the shape and color of the standard mark unit 121 and stores it in the platform 240, and detects all similar markings, thereby preventing the error of readout thirdly. Plays a role.

In the time mark search step (S32), the mark sensor (A) can be moved to move the mark sensor (A) arranged in the standard mark part (121) to the time mark part (122) arranged in the horizontal column and the time mark part (4) arranged in the vertical column. ) Is a step of searching the time mark.

For example, the time mark unit 122 includes a time mark unit for guiding an identification code column for identifying the type of item in the paper 110, a time mark unit for guiding the personal information column of the author, and a selection to select for each item It consists of a time mark section that guides the gyran, and has a configuration that searches for a time mark section based on a standard mark section arranged close to the mark sensor (A) located in each section.

The marking cell path search step (S33) starts with the standard mark unit 121 and moves to a specific reading path in the in-focus direction starting from the out-of-focus of the reading card 100, and the time mark unit 122 is formed. The marking cell 130 and the horizontal row of marking cells are individually searched to perform a role of detecting a more perfect marking than the existing one.

The read card processing step (S40) is a step of deriving a result by comparing the read data with the recommended data.

The read card processing step (S40) first requires a process of generating recommended data through the setting unit 241 of the platform 240, and a template generating step (S41) of generating a template of the reading card through the setting unit, Marking cell application step (S42) for designating the number of marking cells such as an identification code field, a personal information entry field, a check box for an item, and a marking cell arrangement step (S43) for arranging an interval between the designated marking cells 130 ), the marking shape input step (S44) for registering the recognizable marking shape and color information, and the storage setting step (S45) for specifying the storage format of the platform.

In the state where the recommended data prepared based on the above process is prepared on the platform 240, the read data generated through the reading card reading step (S30) is compared and analyzed with the recommended data being prepared on the platform. The analysis method is determined according to the operator's selection. Basically, if the position of the marking described in the marking cell 130 of the read data matches the position of the marking applied to the marking cell of the recommended data, it is regarded as a correct answer, and if the position is different It is regarded as an incorrect answer and results.

The optical mark reading processing method supporting marking recognition and image file conversion based on the reference coordinate value of the present invention, which is composed of the above-described process, is equipped with hundreds of thousands of reading cards in the optical mark reader and the optical mark reader. The scan function converts the reading card to an image file for reading, and the read card converted to an image file and the read result data can be stored on a PC to store and manage hundreds or thousands of reading card information more conveniently than before. You can. In addition, the manual setting function that allows the user to directly specify the shape and color of the individual recognition unit through the function of changing the setting information of the individual recognition unit provided in the optical mark reader, and based on the read data obtained through the repeated reading operation by the optical mark reader By using the generated big data, an automatic setting function for recognizing the type and color information of an individual recognition unit by itself is provided, so that the individual recognition unit setting function is actively read even when the individual recognition unit is damaged. In addition, by registering the shape of the individual recognition unit or the shape of the recommended marking in advance through the setting function provided in the optical mark reader, it is possible to recognize all of the various types of marking described in the marking cell without errors based on the registered information. In addition, even if the read card being input to the optical mark reader is out of the preset input line in the process of being input, since the plurality of mark sensors simultaneously read a plurality of individual recognition units formed on the read card from all directions, the gap of the position deviated is corrected by itself. This results in a faster and more accurate reading action.

The present invention described above has been described with reference to one embodiment shown in the drawings, but this is only an example, and various modifications and equivalent other embodiments are possible from those skilled in the art. Should be clarified.
