The answer sheet supply unit 130 includes a plurality of answer sheets 502 for which an answer is completed, and supplies the answer sheet toward the image capturing means 120 and the transfer guide unit 150 one by one at a predetermined time interval. . At this time, the answer sheet supplied from the answer sheet supply unit 130 is preferably supplied standing up vertically.

The image capturing means 120 captures an image of the entire surface of the answer sheet and converts the image into digital data and transmits the corresponding digital image data to the answer sheet scoring system 100. At this time, a generation time is generated together with the generation of the digital image data. The generation time of the image data may be used to prevent fraud such as replacement of a specific answer sheet. Specifically, the image capturing means 120 may be a scanner, a digital camera, or the like.

On the other hand, the answer sheet can be used in addition to the OMR card, OCR card as described in the prior art a variety of answer sheet. In addition, as shown in FIG. 4, the multiple-choice answer is described on the front side and the subjective answer (not shown) is written on the back side. I can image. In the case where the images of the front and rear surfaces of the answer sheet are respectively photographed, the front and rear images are selectively stored in the DB block 110 to be described later. At this time, the image data of the answer sheet to be stored will be referred to as the original data image.

The transfer guide unit 150 serves to guide the sheet to provide a stable answer sheet. The sorting stacker 140 is an answer sheet supplying section 130, the image pickup means 120 and the transfer guide section 150 where the answer sheet is sorted and loaded with at least one or more detailed stacking box to check the basic information to be described later Through this process, it sorts and loads the answer sheets with errors.

The answer sheet scoring system 100 includes all the components of the answer sheet scoring apparatus according to the present invention, that is, the answer sheet supply unit 130, the image pickup unit 120, the transfer guide unit 150, the sorting stacker 140, and the predetermined stacking box 140. It forms a communication connection and controls each component and controls a series of answer sheet scoring processes according to the present invention.

The answer sheet scoring system 100 implementing the answer sheet scoring method according to the present invention will be described in detail as follows.

First, as shown in FIG. 2, the answer sheet scoring system 100 according to the present invention includes a control module 101, an image capturing means 120, a basic information check module 102, a standard answer generating module 105, It consists of a combination of the multiple choice answer check module 103, the short answer answer recognition module 104 and the DB block 110.

The control module 101 establishes a predetermined communication connection relationship with all components of the answer sheet scoring system according to the present invention, and controls the overall answer sheet scoring process.

The basic information check module 102 is stored in the DB block 110 for basic personal information of the test taker who took the test, for example, basic information such as a name and a social security number (see reference numeral 301 of FIG. 3). It compares and checks basic information. The checking process for the candidate's basic information may use an image processing method. The image processing method will be described in detail later. The basic information check result checked through the image processing method is selectively stored in the DB block 110 under the control of the control module 101. On the other hand, in addition to the basic information check method through the image processing method by the operator in charge of scoring the answer after checking the basic information of the corresponding answer sheet, the check result is input through the input means to be described later the DB under the control of the control module 101 It may optionally be stored in block 110.

The standard answer generating module 105 fills out the standard answer for the multiple-choice answer on the same answer sheet used by the test taker and prepares the standard answer sheet, and converts the image to the digital image data by imaging the standard answer sheet. Do this. The image data for the generated standard answer is selectively stored in the standard answer DB 112 of the DB block 110 described later.

The multiple-choice answer check module 103 serves to score a multiple-choice answer portion of the answer sheet of any candidate. Specifically, the scoring of the multiple-choice answer of the specific answer sheet is performed through a comparison process with the standard answer generated by the standard answer generation module 105. The comparison process between the candidate answer and the standard answer is performed through the image processing method as described above.

More specifically, the image processing method will be described. The multiple-choice answer check module 103 extracts and generates a standard template for a multiple-choice answer portion (see 401 in FIG. 4) from the standard answer. Extracting and generating the standard template may use a known image processing theory. In detail, the standard template may be generated by dividing an image into a plurality of pixels and using contrast information and position information of the corresponding pixels. In this state, the multiple-choice answer check module 103 generates a standard template for the predetermined check in the same manner as in the standard template generation process for the multiple-choice answer portion of the specific answer sheet (refer to reference numeral 302 of FIG. 3). Extract and create a template. Then, by comparing and analyzing the standard template and the template for checking by the multiple-choice answer check module 103, it is possible to obtain a scoring result for the multiple-choice answer of the answer sheet to be checked.

The above image processing method is equally applied to the basic information checking process as described above in addition to the multiple-choice answer checking process. In the basic information checking process, the standard template is extracted from the basic information stored in the DB block 110. Can be.

The short answer answer recognition module 104 plays a role of mediating a scoring process for the short answer answer part of a test taker's answer sheet. The actual scoring process of the short answer answer is made by a worker in charge of answer sheet scoring, and the worker inputs a short answer scoring result through the input means 107 and the short answer answer recognition module 104 is a corresponding short answer answer. Recognizes a scoring result and selectively stores the scoring result in the scoring information DB 115 of the DB block 110. At this time, the subjective answer scoring method by the operator can be largely divided into two, one of the state, the image data of the original answer sheet stored in the DB block 110 is displayed on the display means 106 to be described later In the answer to the answer of the answer form of the answer sheet, and the other is the way that the worker to mark the answer sheet by hand. In the latter case, the completed answer sheet is again converted into image data and stored in the image data DB 111 of the DB block 110, where the converted image data is secondary image data to distinguish it from the original image data. It will be called.

The DB block 110 stores all the data required for the answer sheet scoring method according to the present invention. Specifically, the DB block 110 includes the image data DB 111, the standard answer DB 112, and the basic information DB. 113, classification information DB 114, and scoring information DB 115. As shown in FIG.

The image data DB 111 stores the front and / or rear image of any answer sheet inputted from the image capturing means 120 under the control of the control module 101. In this case, the generation time of each image data may be stored together in the image data DB 111. In addition, the image data DB 111 stores image data on the answer sheet completed by hand, that is, secondary image data. The standard answer DB 112 stores a standard template for a standard answer generated by the standard answer generating module 105 and a multiple choice answer generated and extracted from the standard answer. The basic information DB 113 stores basic personal information of all the test takers who have taken the test, for example, basic information such as name, resident registration number, and the like. In this case, the basic information may be described in a predetermined answer sheet form and the basic information portion may be stored in a standard template format. The classification information DB 114 stores the basic information check result information performed by the basic information check module 102 and stores check result information on whether the basic information matches. The scoring information DB 115 stores the final scoring information which is a result of the scoring process performed by the multiple-choice answer check module 103 and the multiple-choice answer recognition module 104.

In addition to the above components, the answer sheet scoring system according to the present invention further includes a display means 106, an input means 107, and an output means 108. The display means 106 is an operation performing state in which an answer sheet scoring process is generated according to the present invention, for example, a display of an image of an answer sheet inputted from the image capturing means 120, a multiple-choice and subjective answer check process. And so on. The input means 107 serves to enable the input of the various events required to perform the answer sheet scoring process according to the present invention, the output means 108 is performed by the basic information check module 102 It outputs the result data of whether the basic information matches and the scoring result information about the short answer and the multiple choice answer.

Meanwhile, the answer sheet scoring system having the configuration as described above may have an electrical and physical connection relationship with the predetermined answer sheet supply unit 130 and the sorting stacker 140 as shown in FIG. 5. The answer sheet supplying unit 130 supplies the answer sheet 502 one by one to the image capturing means 120 in a state in which a plurality of answer sheets for which answer preparation is completed is loaded under the control of the control module. In this case, the answer sheet 502 may be supplied from the answer sheet supply unit 130 through a transfer means 501. In addition, the sorting stacker 140 has at least one detailed stacking box and serves to classify and load the answer sheet having an error through the basic information check process.

Referring to the operation of the answer sheet scoring apparatus according to the present invention having the above configuration, that is, the answer sheet scoring method according to the present invention.

First, as shown in FIG. 2, a plurality of answer sheets having completed the short answer and multiple choice answers are prepared. The plurality of answer sheets may be loaded in the answer sheet supply unit 130 (S201), and may be extracted one by one from the answer sheet supply unit 130 and supplied to the image capturing means 120.

When the answer sheet is supplied to the image capturing means 120, the image capturing process of the plurality of answer sheets and the conversion into digital data are sequentially performed using the image capturing means 120 (S202). At this time, each generated original image data has a unique generation time.

The original image data of the answer sheet is selectively stored in the image data DB 111 of the DB block 110 under the control of the control module 101. At this time, the generation time of each original image data is also stored in the image data DB 111 (S203). The generation time of the image data serves to prevent the wrong replacement of the answer sheet. Because the plurality of answer sheets are sequentially converted into image data in time series, when an image of a specific answer sheet is replaced, the authenticity of the image of the answer sheet can be determined with reference to the generation time.

In step S204, the original image data of the plurality of answer sheets is stored in the image data DB 111 of the DB block 110. The basic information checking process refers to a process of comparing candidate basic information such as name and resident registration number described in each answer sheet with basic information previously stored in the basic information DB of the DB block 110. As described above, the basic information comparison and checking process may include a method using an image processing method and a user manual method. In the case of using an image processing method, a standard template for basic information stored in the basic information DB 113 is compared with a template for checking a basic information portion of a specific answer sheet, and the result of the check is transmitted to the classification DB. In the manual method, the operator manually determines whether the basic information is inconsistent and inputs the result of checking the basic information into the classification DB of the DB block 110 using the input means 107. .

The comparison of the basic information of the answer sheet and the basic information of the DB block 110 and the check result are selectively stored according to whether the classification information DB 114 of the DB block 110 matches. The error report may be extracted and output through the output means 108. In addition, the answer sheets may be classified and loaded in the classification stacker 140 according to whether the basic information matches (S205).

In this manner, the scoring process is performed in earnest when the basic information checking process is completed (S206). The scoring process can be largely divided into a short answer question scoring process and a multiple choice answer scoring process. The prognostic relationship between the two processes is not significant.

However, in order to proceed with the multiple-choice answer scoring process, a standard answer generation process is required (S208). To generate the standard answer, first, prepare a standard answer sheet in which the standard answer for the multiple-choice answer is written on the same type of answer sheet used by the candidate. In this state, an image is taken of the standard answer sheet and converted into digital image data. In this case, the image pickup means 120 may be used to generate digital image data for the standard answer sheet. Image data for the generated standard answer is optionally stored in the standard answer DB 112 of the DB block 110 under the control of the control module 101.

The multiple-choice answer scoring process is performed while the standard answer is generated. First, the multiple-choice answer check module 103 extracts and generates a standard template for a multiple-choice answer portion (see 401 in FIG. 4) from the standard answer. As a standard of generating the standard template, a known image processing theory may be used as described above. For example, the standard template may be divided into a plurality of pixels, and the standard template may be generated using contrast information and location information of the corresponding pixels. have. In the state where the standard template is generated, the multiple-choice answer check module 103 extracts and generates a check template (see reference numeral 302 of FIG. 3) for the multiple-choice answer part from the answer sheet of the specific test taker (S209). . At this time, the generation criteria of the template for checking corresponds to the generation criteria of the standard template. In this state, when comparing the standard template and the template for checking, it is possible to grasp the difference between the two and the difference means the result of the multiple choice answer scoring. In addition, the multiple-choice answer scoring results are stored in the scoring result DB of the DB block (S210).

On the other hand, the scoring process of the short answer is as follows. The actual scoring process of the short answer answer is made by a worker in charge of answer sheet scoring, and the worker inputs a short answer answer scoring result through the input means 107 and the short answer answer recognition module 104 inputs the corresponding short answer. The grading result of the answer is recognized and selectively stored in the scoring information DB 115 of the DB block 110 (S212) (S213).

At this time, the subjective answer scoring method by the operator can be largely divided into two, one of the state, the image data of the original answer sheet stored in the DB block 110 is displayed on the display means 106 to be described later In the answer to the answer of the answer form of the answer sheet, and the other is the way that the worker scores by hand ((記 記)) to target the real answer sheet (S214). In the latter case, the completed answer sheet is again converted into image data and stored in the image data DB 111 of the DB block 110, wherein the converted image data is secondary image data as described above (S215). ). In addition, when the short answer is scored by hand, a process of comparing the original image data and the secondary image data with each other and determining whether there is an error may be added (S216).

Subsequently, when a predetermined verification process is performed on the scoring information, the answer sheet scoring method according to the present invention is completed.

Answer sheet scoring apparatus and method according to the present invention has the following effects.

By comparing and analyzing the standard and specific answers using image processing techniques, it is possible to prevent scoring errors and maximize the scoring efficiency. Can secure the answer sheet scoring process.

In addition, it is possible to use a variety of answer paper in addition to the optical reading card, such as the conventional OMR, OCR card has the advantage that can significantly lower the test management cost.
