For example, if the paper test question is in handwritten format, the test question in the test question scanned image is in the same handwritten format; in the test question scanned image, the test questions may be continuously arranged, that is, there is no excessive information between the test questions (for example, intermediate interval paragraphs), or the test question information may be non-continuously arranged, such as Figure 1B As shown in the figure, there is "

Answer

Answer

[0036] Optionally, in the disclosed embodiment of the present invention, obtaining at least one test question area image in the test question scanned image includes: obtaining at least one test question area image in the test question scanned image through a first target detection model. The target detection model is an image recognition model built based on a neural network (for example, a neural network based on a Transformer architecture, a convolutional neural network, and a recurrent neural network), which is trained with pre-labeled training samples and is used to detect the positions of one or more targets in an image and mark the target positions in the image; wherein the target positions can be marked in the form of a rectangular annotation box through a boundary matrix; such as Figure 1D As shown, the first target detection model is used to detect one or more test question area images in the test question scan image, and annotate each test question area image in the form of a rectangular annotation frame.

[0037] S120, obtaining an answer area in the question area image, and configuring an answer window in the answer area.

[0038] After obtaining the test question area image, the entire area of ​​the test question area image can be used as the answer area, that is, a click instruction is configured for the test question area image. When the click instruction is obtained in the test question area image, the answer window is displayed to improve the convenience of the user answering questions; wherein, the answer window can be configured as a fixed-size display pop-up window.

[0039] Optionally, in the disclosed embodiment, the step of obtaining the answer area in the test area image includes: if the test area image includes at least one area to be filled, the at least one area to be filled is used as the answer area; if the test area image does not include an area to be filled, the test area image is used as the answer area. When the user clicks on the answer area, a corresponding answer window will pop up, and when the user clicks on other areas in the test area image except the answer area, the answer window will not pop up; Figure 1EAs shown, through text recognition of the test question area image, if identification symbols such as brackets or underlines are obtained in the test question area image, and the above identification symbols do not include text content (for example, fill-in-the-blank questions, multiple-choice questions, and true-or-false questions all include corresponding answer positions such as brackets or underlines), the location of the above identification symbols is determined as the area to be filled, and click instructions are configured for each area to be filled. When the click instruction is obtained through the area to be filled, the corresponding answer window is displayed to obtain the user's answer information to ensure the standardization of the user's answers, that is, to guide the user to answer questions in the area to be filled; if the above identification symbols are not obtained in the test question area image (for example, the question-and-answer questions do not include answer positions such as brackets or underlines), the entire area of ​​the test question area image is used as the answer area, and a click instruction is configured for the answer area. That is, when the click instruction is obtained through any area of ​​the test question area image, the answer window is displayed to obtain the user's answer information, thereby improving the convenience of the user's answering.

[0040] Optionally, in the disclosed embodiment, after obtaining the answer area in the question area image, it further includes: obtaining the question type of the question area image; the configuration of the answer window of the answer area includes: configuring the answer window of the answer area according to the question type of the question area image. According to whether the question area image in the above technical solution includes an area to be filled, it can be determined whether the question type is one of fill-in-the-blank, multiple-choice, and true-or-false questions, or a question-and-answer question; different question types in the question area image have different corresponding answer window sizes. Taking the above technical solution as an example, if the question type is a fill-in-the-blank, multiple-choice, or true-or-false question, only a small amount of text input content from the user needs to be obtained, such as the serial number of the option and the words filled in. Therefore, a smaller answer window can be configured to accommodate the text input content and ensure a better text display effect; if the question type is a question-and-answer question, more input content from the user needs to be obtained. Therefore, a larger answer window can be configured to facilitate the user to browse the complete text input information when answering questions.

[0041] Optionally, in the disclosed embodiment, the step of obtaining the type of the test question in the test question area image includes: if the test question area image includes at least one area to be filled in and multiple option areas, determining that the type of the test question in the test question area image is a multiple-choice question; if the test question area image includes at least one area to be filled in and does not include an option area, determining that the type of the test question in the test question area image is a fill-in-the-blank question or a true-or-false question; if the test question area image does not include an area to be filled in, determining that the type of the test question in the test question area image is a question-and-answer question. For the type of test question in the test question area image, the type of test question can also be further determined by whether it includes an area to be filled in and an option area; Figure 1FFor example, the option information in the option area uses the form of "English letter + dot + space" as the starting information, and the question area image of each multiple-choice question includes at least two option information. Therefore, if at least one area to be filled in is obtained in a question area image, and two or more option areas are also included, then the question in the question area image is determined to be a multiple-choice question; if only an area to be filled in is obtained in a question area image, and no option area is obtained, then the question in the question area image is determined to be a fill-in-the-blank question or a true-or-false question; if a question area image does not include an area to be filled in, then the type of question in the question area image is determined to be a question-and-answer question, and the type of question in the question area image is further determined based on this.

[0042] Optionally, in the disclosed embodiment, configuring the answer window of the answer area according to the question type of the question area image includes: if it is determined that the question type of the question area image is a multiple-choice question, configuring the answer window of the answer area according to the option information in the multiple option areas. In different question types, in addition to the different sizes of the answer window, the display information in the answer window is also different; for multiple-choice questions, the answer window can include option information of each option area, provide users with various options that can be clicked and selected, and obtain the user's answer by obtaining the user's option click instruction, thereby improving the convenience of the user's answering.

[0043] Optionally, in the disclosed embodiment, after determining that the type of the test question in the test question area image is a fill-in-the-blank question or a true-or-false question, it further includes: obtaining the semantics of the text in the test question area image, and determining whether the type of the test question in the test question area image is a true-or-false question based on the semantics of the text; configuring the answer window in the answer area based on the type of the test question in the test question area image includes: if it is determined that the type of the test question in the test question area image is a true-or-false question, configuring the right or wrong option information in the answer window in the answer area. By obtaining the semantics of the text in the test question area image, it can be determined whether the test question in the test question area image is a fill-in-the-blank question or a true-or-false question. If it is determined to be a true-or-false question, the answer window includes a "right" option and a "wrong" option to provide the user with clickable information, and obtain the user's answer by obtaining the user's option click instruction, thereby improving the convenience of the user's answering; if it is determined to be a fill-in-the-blank question, the answer window only needs to include a text input box, and obtain the user's input text in the text input box.

[0044] Optionally, in the embodiment of the present disclosure, obtaining the answer area in the test area image includes: obtaining the answer area in the test area image through a second object detection model. Figure 1FAs shown, the second target detection model is used to detect the to-be-filled areas and option areas in the test question area image, and mark each to-be-filled area and option area in the form of a rectangular annotation box; if at least one to-be-filled area is detected, the obtained to-be-filled area is used as the answer area; if no to-be-filled area is detected, the entire test question area is used as the answer area.

[0045] Optionally, in the disclosed embodiment, before obtaining at least one test question area image in the test question scan image, it also includes: performing image binarization on the test question scan image. Image binarization is to set the grayscale value of the pixel on the image to 0 or 255, that is, if the original grayscale value of the pixel is greater than or equal to the preset pixel threshold, the grayscale value of the pixel is set to 255; if the original grayscale value of the pixel is less than the preset pixel threshold, the grayscale value of the pixel is set to 0, so that the image presents an obvious black and white effect, so as to reduce the amount of data in the image and highlight the text content in the image.

[0046] S130: Obtain the at least one configured test question area image.

[0047] The configured test question area image is an image of the area where each test question is located, which is directly captured based on the scanned image of the test question and can be displayed to the user as an electronic test question, truly restoring the test content of the paper test question. Compared with the electronic test questions obtained by text entry, the accuracy of the test question content is greatly improved. At the same time, through the above technical solution, a corresponding answer window is configured for each test question, converting each paper test question into an electronic test question with an answer function.

[0048] Optionally, in the disclosed embodiment, after acquiring the at least one configured test question area image, it further includes: displaying each configured test question area image according to the test question type of each test question area image. When displaying electronic test questions, the test questions in each test question area image can be classified according to the different test question types, and the test questions of each type can be displayed together and displayed in sequence according to the test question type. For example, the test question area images corresponding to the acquired multiple test questions can be classified according to fill-in-the-blank questions, true-or-false questions, multiple-choice questions, and essay questions, and the test question area images of each type can be displayed in sequence to ensure that users focus on answering questions of a certain question type.

[0049] The technical solution of the disclosed embodiment is to configure the test question area image, which is an image of the area where each test question is located, directly captured on the basis of the test question scanned image, and truly restores the test question content of the paper test question. Compared with text entry, the method of obtaining electronic test questions is simple, the acquisition cost is low, and the accuracy of the test question content is greatly improved. At the same time, a corresponding answer window is configured for each test question, and each paper test question is converted into an electronic test question with an answer function, meeting the user's homework needs.
