Problems solved by technology

[0003] In addition, there may be multiple blank-filling areas in a blank-filling question. In some cases, the relationship between the strings before and after each blank-filling area is highly similar, resulting in difficulties in the corresponding matching operation between each blank-filling area and each marked answer. , which also brings greater operational difficulty to the intelligent correction of fill-in-the-blank questions

[0024] figure 1 A schematic flow chart of the question judgment method in the first embodiment of the present invention is shown. As shown in the figure, the judgment method of this embodiment mainly includes the following steps:

[0025] Step S102, according to the printing area and the handwriting area in the test item image of the test item to be judged, determine the printing detection frame and the handwriting detection frame in the test item image.

[0026] Optionally, the test questions to be judged may be test paper test questions, homework test questions, and the like.

[0027] Optionally, the test question image may be the test question image when the test paper is checked, or the test question image when the homework check is performed, which is not limited in this application.

[0028] Optionally, the test question images of the test questions to be judged can be obtained by shooting, scanning and other means.

[0029] In this embodiment, there is no specific li...

[0044] figure 2 It shows a schematic flow chart of the question judgment method in the second embodiment of the present application. This step is an exemplary implementation of generating a print detection frame and a handwriting detection frame in the above step S102. As shown in the figure, the problem judgment method of this embodiment It mainly includes the following steps:

[0045] Step S202, dividing the test item image according to the text lines in the test item image to obtain at least one target text line.

[0046] In this embodiment, the detection can be performed on the horizontal lines in the test question image, so as to divide the test question image.

[0047] Step S204, acquiring a target text line as the current text line.

[0048] In this embodiment, detection may be performed sequentially on each target text line according to the arrangement position of each target text line in the test question image.

[0049] Step S206, determine the print detection fram...

[0060] image 3 A schematic flow chart of a question-judgment method according to the third embodiment of the present application is shown. This embodiment mainly shows an exemplary implementation of the above step S104. As shown in the figure, the method for judging a question in this embodiment mainly includes the following steps:

[0061] Step S302, identifying each print detection frame, and obtaining each print character in each print detection frame.

[0062] In this embodiment, text recognition can be performed on each print detection frame to obtain each print character string (ie each print character) corresponding to each print detection frame.

[0063] In addition, as mentioned above, since the print detection frame is determined based on the target text line, there may be a handwritten area in the print detection frame. In this case, the handwritten characters in the handwritten area may be replaced by preset placeholders, Please refer to the fourth embodiment fo...

Abstract

A method, device, and computer storage medium for judging a question, mainly comprising: determining a print detection frame containing the print area and a handwriting detection frame containing the handwriting area according to the print area and the handwriting area in the test item image of the test question to be judged; Each printed character identified in the detection frame and the handwritten detection frame, each handwritten character, each printed character position corresponding to each printed character, each handwritten character position corresponding to each handwritten character, obtain the text sequence to be judged of the test question to be judged; and according to The reference answer and each handwritten character in the text sequence to be judged are preset to obtain the judgment result of the test question to be judged. Thereby, the present application can realize the automatic decision of filling in the blank questions, and has higher accuracy of the result of the decision.

Description

technical field [0001] Embodiments of the present invention relate to text recognition processing technology, and in particular to a question judgment method, device and computer storage medium. Background technique [0002] In the intelligent correction scenario of elementary school mathematics problems, the most common type of questions is filling in the blanks. Among them, the forms of filling in the blanks are varied, especially the filling positions are rich and varied, such as filling in the blanks in forms, filling in the blanks with pictures, etc., all of which are one type of filling in the blanks. [0003] In addition, there may be multiple blank-filling areas in a blank-filling question. In some cases, the relationship between the strings before and after each blank-filling area is highly similar, resulting in difficulties in the corresponding matching operation between each blank-filling area and each marked answer. , which also brings greater operational diffic...
