[0021]
[Processing procedure in this system]
Next, the procedure of the confirmation / correction processing of the recognition result of the mark sheet performed by the confirmation / correction system 10 having the above configuration will be described below with reference to FIG. FIG. 7 is a flowchart showing a confirmation / correction processing procedure for a mark sheet recognition result performed by the confirmation / correction system 10 of the present embodiment.
[0022]
First, when a mark sheet confirmation / correction process start command is input from the input device 40 in a state in which the OCR device 30 has already read all mark sheets to be scored, the confirmation / correction object data processing unit 16 may, for example, receive a plurality of answers or nothing. A mark sheet in which a reading situation such as an answer is recognized is determined as a check / correction target mark sheet and extracted. Then, the window screen display unit 17 acquires the list display window screen data from the display window data storage unit 15 and displays a list of the examination number and the like of the confirmation correction target mark sheet on the display device 50 as shown in FIG. ST1).
[0023]
Next, the operator of the present system 10 selects one mark sheet to be checked and corrected from a list such as an examination number displayed on the list display window screen (step ST2).
[0024]
When one mark sheet to be checked and corrected is selected in this way, the window screen display unit 17 subsequently acquires the check and correction window screen data from the display window data storage unit 15, and the display device 50 has a configuration as shown in FIG. The confirmation correction window screen is newly displayed. Here, in this confirmation / correction window screen, in addition to the column indicating the examination number and examinee name in the selected confirmation / correction target mark sheet, all question recognition result display that displays the recognition result of all questions on the confirmation / correction target mark sheet It has an area 100 and a selected question / answer column image display area 200 for displaying an enlarged image of the entire answer column of the question number to be confirmed and corrected.
[0025]
Then, when the above-described confirmation correction window screen is displayed, the image data processing unit 18 acquires the recognition result data of all questions of the confirmation correction target mark sheet from the code data storage unit 12 using the examination number or the like as a key, And based on this code data, the recognition result data corresponding to the said code data is acquired from the said recognition result display position information storage part 14, and the recognition result of all the questions of the said confirmation correction object mark sheet is produced. Then, the obtained recognition result data of all questions is transferred to the window screen display unit 17, and the window screen display unit 17 stores all questions in the confirmation correction target mark sheet in the all question recognition result display area 100 as shown in FIG. Is displayed (step ST3). In this embodiment, it is assumed that the column of question numbers recognized as unanswered or multiple answers among the recognition results of all questions is colored and displayed as shown in FIG.
[0026]
When the operator selects the question number of the question to be confirmed and corrected on the screen on which the recognition results of all questions are displayed in this manner (step ST4), the image data processing unit 18 displays the image in the image display range information storage unit 13. Based on the enlarged range information, enlarged image data of the entire answer column of the selected question number is created. Then, the image data display unit 19 displays the enlarged image data in the selected question / answer column image display area 200 in the confirmation / correction window screen (step ST5).
[0027]
In parallel with the display processing of the enlarged image data, the recognition result data processing unit 20 acquires code data at the question number from the code data storage unit 12 based on the selected question number, Based on the code data, the recognition result data and the recognition result display position data corresponding to the code data are acquired from the recognition result display position information storage unit 14, and the recognition result data and the recognition result display position data are recognized. Transfer to the data display unit 21. Then, the recognition result data display unit 21 displays the recognition result mark 300 in the selected question answer column image display area 200 in the confirmation / correction window screen based on the transferred recognition result data and recognition result display position data (step) ST5).
[0028]
Here, when the display mode of the recognition result mark 300 is specifically shown, the recognition result mark 300 is displayed as shown in FIGS. FIG. 8 shows a display mode when the recognition result of the selected question is “3”, and FIG. 9 shows a display mode when the recognition result is “0”, that is, when the answer is recognized as no answer. Reference numeral 10 denotes a display mode when the recognition result of the selected question is “9”, that is, when a plurality of answers are recognized. As described above, when the mark recognition result is accurately performed, the mark filling portion and the recognition result mark 300 in the enlarged image data are arranged vertically. In the case of no answer or multiple answers, the question number column and the recognition result mark 300 in the enlarged image data are arranged vertically.
[0029]
The operator confirms the recognition status of the mark in a state where the enlarged image data of the entire answer column of the selected question number and the recognition result mark 300 are displayed in the selected question answer column image display area 200 (step ST6). . At this time, when the operator visually recognizes that the mark filling portion and the recognition result mark 300 in the enlarged image data are lined up and down, the operator can confirm that the mark is correctly recognized. The question number to be selected is selected, and the processes after step ST4 are repeated. In addition, when it is visually recognized that the recognition result mark 300 is positioned above the question number column, it can be confirmed that there is a possibility that the recognition result mark 300 is not correctly recognized such as no answer or multiple answers. Is corrected (step ST7).
[0030]
Here, the correction process of the recognition result is performed by inputting a number to be corrected in the recognition result column of the corresponding question in the all question recognition result display area 100. For example, when the recognition result “4” is corrected to “2”, the correction process is completed by selecting “4” and inputting “2”.
[0031]
The case where the mark status confirmed by the above-mentioned enlarged image data and the recognition result do not coincide with each other is recognized as a plurality of answers by recognizing that there is a mark, for example, an eraser scum or dirt left behind. And so on.
[0032]
After the correction process is completed in this manner, the processes in and after step ST4 are performed until the confirmation correction process is performed for all questions. When the confirmation correction for all the questions is completed for this check correction target mark sheet, the steps for the next check correction target mark sheet are performed. Processing after ST1 is performed. When the confirmation and correction processing is performed for all the mark sheets in this way, all processing steps by the system 10 are finished (steps ST8 and ST9).
[0033]
As described above, according to the present system 10, it is not necessary to perform confirmation processing for all questions in a state in which images of all questions on the mark sheet are displayed, and the mark filling portion and the recognition result mark 300 in the enlarged image data Since it is possible to easily perform confirmation processing by visually checking whether or not they are lined up and down, simple and highly accurate confirmation processing can be performed, and the efficiency of confirmation correction processing can be improved.
[0034]
[Other Embodiments]
In the above embodiment, the confirmation process is performed by selecting the question number of the question to be confirmed and corrected for each question. However, the enlarged image data and the recognition result mark from the first question to the last question are selected. For example, as shown in FIG. 11, a scroll button 400 for sequentially displaying 300 in the selected question / answer column image display area 200 of the confirmation / correction window screen is provided at an arbitrary position in the confirmation / correction window screen. In addition, it is possible to efficiently perform confirmation and correction processing for all questions.
[0035]
In the confirmation / correction window screen of FIG. 11, the operator places the cursor on the scroll button 400 of the downward arrow, clicks the mouse, and continues to press the down arrow scroll button 400, thereby selecting the answer to the selected question / answer column image display area 200. Since the respective enlarged image data from the first question to the final question and the recognition result mark 300 can be displayed successively and sequentially, the operator looks at the selected question answer column image display area 200 and enlarges the image data. The quality of the recognition result can be confirmed simply by sequentially determining whether or not the positions of the mark fill-in part and the recognition result mark 300 are vertically aligned.
[0036]
Specifically, when the enlarged image data and the recognition result mark 300 are continuously displayed one after another, the operator visually recognizes a state where the mark filling portion and the recognition result mark 300 in the enlarged image data are aligned vertically. Since it can be confirmed that the mark is recognized correctly, it is only necessary to keep pressing the down arrow scroll button 400 to continue the continuous display. In addition, when the operator visually recognizes the state where the mark filling portion and the recognition result mark 300 in the enlarged image data are not aligned vertically (when it is visually recognized that the recognition result mark 300 exists above the question number column in the enlarged image data) ), The enlarged image data of the question number and the recognition result mark 300 are displayed by pressing the down arrow scroll button 400 or the like, and the correction processing as described above may be performed after confirming the recognition result.
[0037]
As described above, by providing the scroll button 400 in the confirmation / correction window screen, the operator can perform the confirmation / correction processing for all questions more efficiently. Needless to say, as long as the enlarged image data and the recognition result mark 300 can be continuously displayed as described above, the scroll button 400 is not limited to the scroll button 400 shown in FIG.
[0038]
【The invention's effect】
According to the present invention, the operator can easily and accurately visually confirm the quality of the mark recognition result by confirming the positional relationship between the mark filling portion and the recognition result mark in the enlarged image data for the question to be confirmed and corrected. Therefore, the confirmation and correction of the mark sheet recognition result can be performed efficiently and accurately.
