The answer sheet processing system 100 is a system for efficiently performing correctness/incorrectness determination on the completed answer sheet.
The answer sheet processing system 100 includes an answer sheet processing device 1, a scanner 4, and a data server 6. Here, in FIG. 1, only one answer sheet processing device 1 is shown, but a plurality of answer sheet processing devices 1 may of course be provided.

The answer sheet processing device 1, the scanner 4, and the data server 6 are communicatively connected via a communication network N.
The communication network N is, for example, a LAN (Local Area Network), an Internet line, or the like. Here, the specific communication method in the communication network N, whether it is a wired connection or a wireless connection, or the like is not particularly limited.

<Answer sheet processing device 1>
The answer sheet processing device 1 is a terminal used by a grader. The answer sheet processing device 1 is, for example, a personal computer (PC). The answer sheet processing device 1 may be a tablet terminal or a portable terminal having a computer function represented by a smartphone or the like. The answer sheet processing device 1 is provided, for example, in a place where a grader works, such as a school staff room.

As shown in FIG. 2, the answer sheet processing device 1 includes a control unit 10, a storage unit 30, an input unit 36, a display unit 37, and a communication interface unit 39.
The control unit 10 is a central processing unit (CPU) that controls the entire answer sheet processing apparatus 1. The control unit 10 cooperates with the above-described hardware to execute various functions by appropriately reading and executing an operating system (OS) and application programs stored in the storage unit 30.
The control unit 10 includes a sheet image acquisition unit 11 (sheet image acquisition unit, type acquisition unit, completed sheet image acquisition unit), a pre-processing unit 12, and an image output unit 19 (unprocessed image output unit, image output unit). And an answer processing unit 21.

The sheet image acquisition unit 11 acquires an image of an answer sheet (including blank and completed sheets). The sheet image acquisition unit 11 may acquire the answer sheet by causing the scanner 4 to read the answer sheet and receiving the answer sheet image obtained by converting the answer sheet into image data from the scanner 4. Alternatively, the scanner 4 may read the answer sheet and the answer sheet image may be stored in the data server 6 in advance, and the sheet image acquisition unit 11 may obtain the answer sheet image from the data server 6.
Next, the paper image acquisition unit 11 acquires the paper type from the acquired answer paper image. The sheet type indicates the type of answer sheet. For example, in the case of horizontal writing, the sheet image acquisition unit 11 may acquire the title located at the upper left of the answer sheet as the sheet type. Further, for example, in the case of vertical writing, the sheet image acquisition unit 11 may acquire the title located at the upper right of the answer sheet as the sheet type. Further, when the answer sheet is provided with a code or number for identifying the type, the sheet image acquisition unit 11 may acquire this code as the sheet type.

The pre-processing unit 12 performs a process on an unanswered answer sheet image, and executes it before performing a process on a completed answer sheet image.
The pre-processing unit 12 includes a set setting unit 13 (set setting unit), a region extraction unit 14 (region extraction unit), a character acquisition unit 15 (character acquisition unit), and an exclusion set designation unit 16 (excluded set designation unit). And a group ID (IDentification) assigning section 17 (set identification assigning means) and a paper registration section 18 (paper registration means).

The set setting unit 13 extracts a predetermined start symbol and an end symbol paired with the start symbol from the blank answer sheet image acquired by the paper image acquisition unit 11. Then, the set setting unit 13 sets a set including the start symbol and the end symbol. Here, the predetermined start symbol and the end symbol paired with the start symbol may be, for example, a pair of bracket symbols. In addition, the answer sheet processing device 1 stores the start symbol and the end symbol to be paired in the storage unit 30 in advance as a parenthesis symbol storage unit, as shown in FIG. Then, the set setting unit 13 may scan the answer sheet image to extract the start symbol and the end symbol stored in the storage unit 30. Here, the pair setting unit 13 extracts the pair of parentheses because the area surrounded by the pair of parentheses can be a candidate for the answer column.

The region extraction unit 14 extracts a region surrounded by a start symbol and an end symbol for the set set by the set setting unit 13. The area extracting unit 14 can extract, for example, a rectangular area as an area surrounded by the start symbol and the end symbol.
The character acquisition unit 15 performs character recognition processing on the area extracted by the area extraction unit 14, and acquires characters included in the area.

The exclusion set designation unit 16 determines whether to exclude a set corresponding to a region, based on the length of the region extracted by the region extraction unit 14. For example, when the length of the region extracted by the region extraction unit 14 is shorter than a predetermined value, the exclusion set designation unit 16 designates a set corresponding to the region as a set to be excluded. This is because, for example, the set used in a question such as "Write the number that applies to ()." is shorter than the answer column, and the excluded set designating unit 16 Performs processing for excluding such a set.
In addition, the exclusion group designation unit 16 determines whether to exclude a group corresponding to the region, based on the character acquired by the character acquisition unit 15. For example, when a character included in a region is a character to be excluded, the exclusion set designating unit 16 specifies a set corresponding to the region as a set to be excluded. Here, the exclusion target character means, for example, an alphanumeric character used in the headline of a question such as “(1)” or “(a)”. This exclusion target character may be incorporated in the program 31a in advance, for example.

The group ID assigning unit 17 assigns different group IDs (group identification information) to the respective groups set by the group setting unit 13 except for those excluded by the excluded group designating unit 16. The group ID is identification information for identifying the group. The group to which the group ID is assigned by the group ID assigning unit 17 corresponds to the answer column of the answer sheet.
The paper registration unit 18 stores paper form data in which the group ID, the position information of the group to which the group ID is given, and the paper type of the answer sheet image being processed are associated with each other, the paper form storage unit 32 (paper storage unit). To memorize.

The image output unit 19 outputs the answer sheet image acquired by the sheet image acquisition unit 11 to the display unit 37. In addition, the image output unit 19 outputs the answer sheet image processed by the preprocessing unit 12 to the display unit 37.

The answer processing unit 21 includes a writer ID acquisition unit 22 (writer identification information acquisition unit), a set processing unit 23 (written character area acquisition unit), and an answer content registration unit 24 (answer registration unit).
The writer ID acquisition unit 22 acquires, from the completed answer sheet image acquired by the sheet image acquisition unit 11, a writer ID (entrant identification information) that identifies the writer who is the learner who wrote the answer. The writer ID acquisition unit 22 may acquire, for example, a number or the like written in the place where the group and the number are written, and use it as the writer ID. Further, the writer ID acquisition unit 22 may, for example, describe the name column as the writer ID. Here, the acquisition position of the writer ID may be registered in advance by the paper image acquisition unit 11.

The group processing unit 23 extracts the corresponding sheet form data from the sheet form storage unit 32 based on the sheet type of the completed answer sheet image, and recognizes the set of completed answer sheet images. Then, the pair processing unit 23 acquires the area surrounded by the start symbol and the end symbol for each recognized pair.
The answer content registration unit 24 stores the area acquired by the group processing unit 23 in the answer content storage unit 33 (answer content storage unit) in association with the sheet type, the group ID, and the writer ID.

The storage unit 30 is a storage area such as a hard disk or a semiconductor memory device for storing programs, data, and the like necessary for the control unit 10 to execute various processes.

The control unit 10 may cause the storage unit 30 to temporarily store information about the set set.

In S21, the control unit 10 (region extraction unit 14) specifies the region of the set set.
FIG. 7 shows an answer sheet image 74 in which an area is designated for each set included in the answer sheet image 71. In the answer sheet image 74, each rectangular area surrounded by each parenthesis symbol constituting the sets 74a, 74b,... Is designated. In this example, a rectangular area including each parenthesis symbol is designated, but a rectangular symbol may be designated excluding each parenthesis symbol.

In S22 of FIG. 6, the control unit 10 selects one set. The control unit 10 performs processing in units of one set in the subsequent processing.
In S23, the control unit 10 (exclusion group designation unit 16) determines whether or not the length of the area is less than a predetermined value. This process is to determine whether or not the answer column has a certain size or more, and when the length of the area is less than a predetermined value, to determine that it is not the answer column. is there. When the length of the area is less than the predetermined value (S23: YES), the control unit 10 shifts the processing to S27. On the other hand, when the length of the area is not less than the predetermined value (S23: NO), the control unit 10 shifts the processing to S24.

In S24, the control unit 10 (character acquisition unit 15) performs character recognition processing on the area corresponding to the selected set, and determines whether or not the area includes characters. When the area includes characters (S24: YES), the control unit 10 shifts the processing to S25. When the area does not include a character (S24: NO), the control unit 10 shifts the processing to S26.
In S25, the control unit 10 (exclusion group designation unit 16) determines whether the character included in the area is the exclusion target character. When the character is an exclusion target character (S25: YES), the control unit 10 moves the process to S27. On the other hand, when the character is not the exclusion target character (S25: NO), the control unit 10 shifts the processing to S26.

In S26, the control unit 10 (set ID assigning unit 17) assigns an ID to the set being processed. After that, the control unit 10 shifts the processing to S28.
On the other hand, in S27, the control unit 10 (exclusion set designation unit 16) excludes the set being processed and does not recognize it as the answer column.
In S28, the control unit 10 determines whether or not all the sets set in S20 have been processed. When the processing has been performed for all the sets (S28: YES), the control unit 10 shifts the processing to S29. On the other hand, if the processing has not been performed for all pairs (S28: NO), the control unit 10 shifts the processing to S22.

In S29, the control unit 10 (sheet registration unit 18) stores the sheet form data in which the sheet type, the group ID, and the position information of the group are associated with each other in the sheet form storage unit 32. After that, the control unit 10 shifts the processing to S16 of FIG.
FIG. 8 shows an example of the post-setting screen 75 of the answer column including the answer sheet image 76 displayed on the display unit 37 in S16 of FIG.

The post-setting screen 75 includes an answer sheet image 76, a setting processing button 72, and an end button 73. The answer sheet image 76 is obtained after the sheet registration process, and the set ID is attached to the area serving as the answer column from the answer sheet image 71 shown in FIG. In this example, eight groups with group IDs L20203-1 to L20203-8 are registered as answer fields. The area serving as the answer column is displayed in a distinguishable manner by, for example, coloring. Although the set ID is displayed in the example of FIG. 8, the display of the set ID is optional.
Here, the set 76a corresponding to the set 74a of the answer sheet image 74 described in FIG. 7 is a set that represents a question, and is not set as an answer column because the length of the area is less than the predetermined value. On the other hand, the set 76b corresponding to the set 74b of the answer sheet image 74 described in FIG. 7 is designated in the answer column.

In this way, the answer sheet processing device 1 sets a set for an unfilled answer sheet image, determines whether or not to set the set in the answer column based on the area corresponding to the set set, and sets the answer. A set suitable as a column is registered as paper form data. Therefore, at the time of scoring, the answer column for determining correctness can be registered automatically.

Next, the answer content registration process will be described.
FIG. 9 is a flowchart showing the answer content registration processing of the answer sheet processing device 1 according to the present embodiment.
FIG. 10 is a diagram showing an example of the storage unit 30 of the answer sheet processing device 1 according to the present embodiment.

In S30 of FIG. 9, the control unit 10 (the writer ID acquisition unit 22) determines the writer ID by performing, for example, character recognition processing on the acquisition target region of the writer ID of the completed answer sheet image. get. If the answer sheet is completed, the name, group, etc. are entered. Therefore, the control unit 10 can acquire the writer ID for uniquely identifying the completed answer sheet image.
In S31, the control unit 10 (group processing unit 23) extracts the relevant sheet form data from the sheet form storage unit 32 based on the sheet type of the completed answer sheet image. Next, the group processing unit 23 recognizes the group from the completed answer sheet image based on the sheet form data.

(Variation)
(1) In this embodiment, the case where the grader selects the button for starting the process for setting the answer column to automatically set the answer column has been described as an example, but the present invention is not limited to this. For the displayed answer sheet image, the grader, for example, specifies the range by dragging and dropping via the input unit, and the control unit (operation accepting unit) of the answer sheet processing device accepts the operation, You may make it set the answer column included in the range designated by operation.
FIG. 11 is a diagram showing an operation example for designating an answer column in the answer sheet processing apparatus 1 according to the modification.

The pre-setting screen 80 shown in FIG. 11 is displayed on the display unit 37 by, for example, the process of S13 of FIG. Here, when the grader wants to set an answer column for a part of the answer sheet image 81, the grader performs a drag & drop operation with the pointer 82 at the position 81s in the range in which the answer column is desired to be set. Then, the designated range 81e is set. Then, the control unit 10 of the answer sheet processing device 1 may perform the process of setting the set of the start symbol and the end symbol in the designated range 81e.

Further, it is also possible to specify and set one by one as the answer column.
FIG. 12 is a diagram showing another operation example for designating the answer column in the answer sheet processing device 1 according to the modified embodiment.
As shown in FIG. 12A, the grader designates the answer column 91a included in the answer sheet image with the pointer 92 and performs an operation such as double-clicking.
Then, the control unit 10 of the answer sheet processing device 1 searches for a start symbol to the left of the position of the pointer 92 and an end symbol to the right. Then, as shown in FIG. 12B, an area surrounded by the start symbol and the end symbol that can be searched is extracted and set as the answer column 93.

Furthermore, the method of individually setting the answer columns described in FIGS. 11 and 12 may be combined with the method of automatically setting the answer columns described in the present embodiment. That is, after performing the method of automatically setting the answer columns described in the present embodiment, the method of individually setting the answer columns described in FIGS. 11 and 12 may be used as necessary.

(2) In this embodiment, when the set set includes an exclusion target character, the set is set as an exclusion set. However, it is not limited to this. When a character is included in the set set and is not an exclusion target character, the control unit (exclusion word registration means) of the answer sheet processing device stores the exclusion unit as an exclusion word (exclusion word storage) based on the arrangement position of the character. Means). Here, for example, a character described as a unit such as “(person)” corresponds to the character that is the exclusion word. Then, when registering the answer content, the entry content excluding the exclusion word may be stored in the answer content storage unit 33. By doing so, it is possible to register only the entry contents that the learner (entrant) has actually entered in the answer content storage unit 33.

(3) In the present embodiment, an example has been described in which the area corresponding to the specified set is extracted from the completed answer sheet image and stored, but the present invention is not limited to this. For example, character recognition processing may be performed on the extracted area and the obtained character may be stored.

(4) In this embodiment, the horizontal answer sheet has been described as an example, but the present invention is not limited to this. It may be a vertically written answer sheet. In that case, the parenthesis symbols are also in the vertical direction. Therefore, when extracting a region surrounded by the start symbol and the end symbol, scanning may be performed in the vertical direction.
