Example 1

The present invention provides a method for searching questions. Please refer to FIG. 1. The method for searching questions in an embodiment of the present invention includes the following steps:

Step S101: Receive an instruction sent by a user to enable a multi-question search mode.

In this embodiment, when the intelligent terminal is in a dormant state, if an operation of pressing a predetermined button of the intelligent terminal is received from the user, the camera of the intelligent terminal is activated to take a photo containing the test questions to be searched, so as to avoid the user needing complex Only the operations such as booting, unlocking and opening the application can take pictures, so as to realize the purpose of one-key boot. Wherein, the intelligent terminal may be any one of terminal devices such as a smartphone, a smart bracelet, a tablet computer, etc.; the sleep state may be screen off, black screen, screen lock, etc.; the predetermined button may be any physical key; the instruction used to start the camera of the smart terminal to take a photo containing the test question to be searched can also be a preset voice or a predetermined sliding operation by the user on the display screen of the smart terminal, and do not do this. Excessive restrictions.

Optionally, the selection of the question search mode may be completed at a predetermined position of a predetermined APP. Wherein, the APP predetermined by the mobile terminal may be popular application software such as Jobbang; the predetermined position may be any position in the display interface that does not affect the user's viewing of the displayed content, for example, the upper right corner of the display interface, Bottom right, top left, or bottom left.

Optionally, the question search mode may include: a single-question search mode and a multi-question search mode; it can be understood that when the user only searches for one question, he can select one of the above two search modes. any kind.

In this embodiment, the types of the test questions to be searched include but are not limited to: multiple-choice questions, fill-in-the-blank answer questions.

Step S102: After entering the multi-question search mode, obtain a photo containing the question to be searched.

Optionally, the photo containing the test question to be searched may be generated by activating the camera of the smart terminal to shoot.

Optionally, when the user takes a photo, he/she selects to shoot in a landscape orientation.

Optionally, when taking a photo, the user may choose to only take a photo of the part containing the test question to be searched, or may take a photo of the entire content of the page where the test question to be searched is located.

Optionally, when the user chooses to take a photo of the entire content of the page where the test question to be searched is located, the intelligent terminal will automatically crop the photo containing the test question to be searched so that it only contains the test question to be searched. It can reduce the interference content except the test questions that the user needs to search, achieve the purpose of quickly identifying the test questions that the user needs to search for, and improve the efficiency of searching for the test questions.

Step S103: Select each question to be searched from the photo, record the number of the question to be searched selected by the box, and identify each question to be searched selected by the box.

Optionally, in order to explain the above step S103 more clearly, FIG. 2 shows the specific implementation process of obtaining each test question to be searched, and the details are as follows:

As shown in Figure 2, in one embodiment of the present invention, the frame selection of each test question to be searched from the photo includes:

Step S201: performing binarization processing on the photo containing the test question to be searched, and frame-selecting the text part in the photo containing the test question to be searched according to the first preset condition to obtain at least one text box;

Wherein, the above-mentioned binarization processing process may include:

Grayscale processing is performed on the obtained photo containing the question to be searched to obtain a grayscale image containing the question to be searched;

Segmenting the barcode area in the grayscale image to obtain a black and white image of the grayscale image;

The black and white images are located, and the located black and white images are corrected.

In this embodiment, the first preset condition may be: box-selecting the question stems in the photo containing the test question to be searched row by row; box-selecting the options in the photo containing the test question to be searched one by one.

Exemplarily, as shown in FIG. 3 , when the type of the test question to be searched is multiple-choice questions, the complete part of each test question includes the content of the question stem and the options. At this time, when performing the box selection operation, the question stems should be box-selected line by line, and the four options should be box-selected one by one. Specifically, it can be as follows: first, select the first line of the question stem to obtain text box 1 (the largest text box above); then select A, B, C, and D in the four options below the question stem. Four corresponding text boxes are obtained, from left to right are text box 2, text box 3, text box 4, and text box 5.

Step S202: Calculate the area and center point coordinates corresponding to each of the text boxes;

Optionally, each text box obtained after frame selection is a regular rectangle. Therefore, when calculating the area of each of the text boxes, the area of each of the text boxes can be calculated mathematically, that is, the area of each of the text boxes can be obtained by using the formula S=ab, where a represents the length of each rectangle, b Indicates the width of each rectangle.

Optionally, the coordinates of the center point of each text box may be the geometric center position of each text box.

Step S203: According to the area of each text box and the second preset condition, cluster the coordinates of each center point to obtain each complete test question to be searched.

In this embodiment, the second preset condition may be: the sequence of questions and options preset in the photo containing the test questions to be searched.

Optionally, the area of each text box is the weight value of each center point during clustering.

Optionally, the obtained number of test questions to be searched may also be obtained by clustering. The clustering operation in this embodiment can use a common clustering algorithm. Taking FIG. 3 as an example, the initial cluster center is the geometric center of the text box 1, and the center point coordinates of the remaining text boxes and the center of the text box 1 are calculated. The distance between point coordinates, select the text box closest to the geometric center of the text box 1 as the class to which the sample belongs. Wherein, the distance can be obtained by using a distance calculation method between two points on a plane. It can be understood that, after performing multiple clustering operations, if the number of questions to be searched remains unchanged, the number can be taken as the actual number of questions to be searched.

It should be noted that for multiple-choice questions, it is often affected by various factors such as the number of test questions and paper, resulting in a relatively close distance between the two test questions before and after. At this time, clustering operations often require additional pre-set conditions. for clustering judgment. Optionally, clustering judgment is performed using the sequence of question stems and option settings as auxiliary conditions.

For the convenience of description, when the question stems and options of the second test question are box-selected respectively, the obtained text boxes are all represented by dashed boxes. Exemplarily, when the second test question as shown in Figure 3 needs to be clustered, frame selection can be performed first according to the method described in step S201, and six text boxes marked with dotted lines are obtained as shown in Figure 4; Then use the center coordinate of the text box with the largest dotted line as shown in Figure 4 as the initial class center for clustering. At this time, because of the addition of the sequence of question stem and option settings, it can be judged whether it is the same question or not. auxiliary conditions. Therefore, when judging the complete part of the second question, the 4 options above the question stem closest to the second question will not be classified as the rest of the same question as shown in Figure 5; As shown in 6, the 4 options below the question stem closest to the second question are classified as the rest of the same question, which improves the accuracy of classification and the correct rate of frame selection.

Optionally, each question to be searched selected by the box may be identified by optical character recognition (Optical Character Recognition, OCR). After the photo containing the test question to be searched is recognized by OCR, the text information contained in the photo will be extracted.

Step S104: Upload the number of the question to be searched selected by the box and the content of the identified question to be searched to the server for question matching.

In this embodiment, the identified content of the test question to be searched, that is, only the text information, is uploaded as the uploaded content, so as to avoid upload failure caused by factors such as the size of the picture or the inappropriate pixels, which can improve the upload process. speed to achieve the purpose of fast matching.

Optionally, the server stores a high-frequency question bank and a question list containing the to-be-searched questions.

Optionally, after receiving the frame-selected number of questions to be searched and the identified text information, the server first searches the high-frequency question bank. After describing the test questions that match the test questions to be searched; then start a second search in the question sea. Wherein, the matching may include: test questions that are identical to or equivalently deformed to the test questions to be searched.

Optionally, after searching the to-be-searched question in the high-frequency question bank, the high-frequency question bank is updated in time according to the number of searches for the same question in the high-frequency question bank.

Step S105: Receive and display the problem-solving result fed back by the server and corresponding to the to-be-searched question matched this time.

Wherein, the number of the problem-solving results is less than or equal to the number of the to-be-searched questions. It can be understood that, after the secondary search is performed according to the method described in step S104, if no question matching the to-be-searched question is found in the question sea within the preset time period, the server feedback at this time is the same as this time. The number of solution results corresponding to the matched test questions to be searched will be smaller than the number of the to-be-searched questions.

Optionally, after receiving each question to be searched in the frame selected from the photo, the server first performs content correction to reduce the probability that the matching question cannot be searched due to errors in the question itself.

Optionally, the search result fed back by the server may include: the correct answer of the test question to be searched and/or the problem-solving idea of the test question to be searched. In order to inspire students to think, after finding the question that matches the question to be searched, before sending the correct answer to the question to be searched, the solution idea of the question to be searched may be sent to the user, so that the user can After obtaining the problem-solving idea, you can try to answer the question first, after the user has solved the to-be-searched question according to the problem-solving idea of the to-be-searched question sent by the server, or after the user obtains the problem-solving idea of the to-be-searched question. Still unable to start, then send the correct answer to the question to be searched to the user.

Optionally, if the user can try to answer the question after obtaining the solution idea of the question to be searched, after sending the correct answer of the question to be searched to the user, the user's final answer is counted, and the user is On the display interface of the reservation APP, it is convenient for the user to view.

As can be seen from the above, in this embodiment of the present invention, at least one text box is obtained by box-selecting the text part in the photo containing the test question to be searched according to the first preset condition, so that the corresponding text box can be obtained. area and center point coordinates; through the area of each text box and the second preset condition, the coordinates of each center point are clustered, and the complete test question to be searched can be obtained; through two frame selections To further determine the complete part of the test questions to be searched, each complete test question can be searched as an independent search object, making the above-mentioned questions to be searched easier to identify, effectively improving the accuracy of the search questions, and having a strong ease of use and practicality.
