Example one
The present invention provides a method for searching for questions, please refer to fig. 1, the method for searching for questions in the embodiment of the present invention includes the following steps:
step S101: and receiving an instruction for starting a multi-channel test question searching mode sent by a user.
In this embodiment, when the intelligent terminal is in a dormant state, if an operation that a user presses a preset key of the intelligent terminal is received, the camera of the intelligent terminal is started to shoot a picture containing a test question to be searched, so that the user is prevented from taking a picture only by complicated operations such as starting, unlocking, opening an application program and the like, and the purpose of starting up the terminal by one key is achieved. The intelligent terminal can be any one of terminal equipment such as a smart phone, a smart bracelet, a tablet computer and the like; the dormant state can be screen off, screen blacking, screen locking and the like; the preset key can be any one physical key; the instruction for starting the camera of the intelligent terminal to shoot the photo containing the test questions to be searched can also be a preset voice or a preset sliding operation of a user on a display screen of the intelligent terminal, and therefore excessive limitation is not imposed.
Optionally, the selection of the question searching mode may be completed at a predetermined position of a predetermined APP. The APP preset by the mobile terminal can be hot application software such as a job help; the predetermined position may be any position in the display interface that does not affect the user's viewing of the display content, for example, the upper right corner, the lower right corner, the upper left corner, or the lower left corner of the display interface.
Optionally, the topic searching mode may include: a search mode of single-channel test questions and a search mode of multiple-channel test questions; it is to be understood that when the user performs only one test question search, either of the two question search modes may be selected.
In this embodiment, the types of the test questions to be searched include, but are not limited to: selecting questions, filling in blank questions, solving and answering the questions.
Step S102: and after entering the multi-channel test question searching mode, acquiring a photo containing the test question to be searched.
Optionally, the photo containing the test question to be searched may be generated by starting a camera of the intelligent terminal to shoot.
Optionally, when the user takes a picture, the user selects horizontal screen shooting.
Optionally, when taking a picture, the user may select to take only the portion containing the test questions to be searched, or may take a picture of the entire content of the page where the test questions to be searched are located.
Optionally, when the user selects to photograph all the contents of the page where the test questions to be searched are located, the intelligent terminal automatically cuts the photos containing the test questions to be searched, so that the photos only contain all the information of the test questions to be searched, interference contents except the test questions to be searched by the user are reduced, the purpose of quickly identifying the test questions to be searched by the user is achieved, and the efficiency of searching the test questions is improved.
Step S103: and selecting each test question to be searched from the picture frames, recording the number of the test questions to be searched selected from the frames, and identifying each test question to be searched selected from the frames.
Optionally, to describe the step S103 more clearly and clearly, fig. 2 shows a specific implementation flow for obtaining each test question to be searched, which is detailed as follows:
as shown in fig. 2, in an embodiment of the present invention, the selecting each test question to be searched from the photo frame includes:
step S201: carrying out binarization processing on the photo containing the test questions to be searched, and framing character parts in the photo containing the test questions to be searched according to a first preset condition to obtain at least one text box;
wherein, the binarization processing process may include:
carrying out gray processing on the obtained picture containing the test questions to be searched to obtain a gray image containing the test questions to be searched;
segmenting the bar code region in the gray level image to obtain a black and white image of the gray level image;
and positioning the black-and-white image, and correcting the positioned black-and-white image.
In this embodiment, the first preset condition may be: framing the question stem in the photo containing the test question to be searched line by line; and selecting options in the photos containing the test questions to be searched one by one.
Illustratively, as shown in fig. 3, when the type of the test questions to be searched is a choice question, the complete part of each test question contains two parts, namely a question stem and a choice. At this time, when the frame selection operation is performed, the question stem is subjected to frame selection line by line, and the four options are subjected to frame selection one by one. The method specifically comprises the following steps: firstly, carrying out frame selection on a first line of a question stem to obtain a text box 1 (the text box with the largest upper surface); and then A, B, C, D of the four options below the question stem are respectively selected one by one to obtain 4 corresponding text boxes, namely a text box 2, a text box 3, a text box 4 and a text box 5 from left to right.
Step S202: calculating the area and the center point coordinate corresponding to each text box;
optionally, each text box obtained after the 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 may be obtained by a mathematical method using the formula S ═ ab, where a denotes the length of each rectangle and b denotes the width of each rectangle.
Alternatively, the coordinates of the center point of each text box may be the geometric center position of each text box.
Step S203: and clustering the coordinates of each central point according to the area of each text box and a second preset condition to obtain each complete test question to be searched.
In this embodiment, the second preset condition may be: the sequence between the question stem and the option preset in the photo containing the test question to be searched.
Optionally, the area of each text box is a weight value of each central point in clustering.
Optionally, the number of the test questions to be searched can be obtained by clustering. The clustering operation in this embodiment may use a common clustering algorithm, taking fig. 3 as an example, the initial class center is the geometric center of the text box 1, the distances between the coordinates of the center points of the remaining text boxes and the coordinates of the center point of the text box 1 are calculated, and the text box closest to the geometric center of the text box 1 is selected as the class to which the sample belongs. Wherein, the distance can be obtained by adopting a distance calculation method between two points on a plane. It can be understood that, after performing the clustering operation for a plurality of times, if the number of the obtained test questions to be searched remains unchanged all the time, the number can be used as the actual number of the test questions to be searched.
It should be noted that, for the choice questions, the distance between two previous and next test questions is relatively close due to the influence of various factors such as the number of test questions and paper, and at this time, clustering needs to be performed by adding some preset conditions to perform clustering judgment. Optionally, the order of the question stem and the option setting is used as an auxiliary condition to perform clustering judgment.
For convenience of description, when the question stem and the option of the 2 nd test question are respectively selected, the obtained text boxes are all represented by dashed boxes. For example, when the 2 nd test question shown in fig. 3 needs to be clustered, the method described in step S201 may be firstly performed to perform frame selection, and 6 text boxes identified by dashed lines are obtained as shown in fig. 4; then, the center coordinate of the text box with the largest dotted line in fig. 4 is used as the initial class center for clustering, and at this time, an auxiliary condition that whether the test questions are the same is judged according to the sequence of the question stem and the option setting is added. Therefore, when the complete part of the 2 nd test question is judged, 4 options above the question stem closest to the 2 nd test question are not classified as the rest contents of the same test question as shown in fig. 5; instead, as shown in fig. 6, 4 options below the stem closest to the 2 nd test question are classified as the rest of the same test question, so that the classification precision and the frame selection accuracy are improved.
Alternatively, each of the test questions to be searched selected by the frame may be recognized by an Optical Character Recognition (OCR) technique. And after the photo containing the test questions to be searched is identified by OCR, extracting character information contained in the photo.
Step S104: and uploading the number of the test questions to be searched selected by the frame and the content of the identified test questions to be searched to a server for matching the test questions.
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 that uploading failure caused by factors such as the size of a picture or pixel incompatibility is avoided, uploading speed can be increased, and the purpose of fast matching is achieved.
Optionally, the server stores a high-frequency question bank and a question sea containing the test questions to be searched.
Optionally, after receiving the number of the framed test questions to be searched and the identified text information, the server searches in a high-frequency question bank first, and if no test question matched with the test question to be searched is found within a preset time length; a second search in the foreign sea is started. Wherein the matching may include: the test questions are completely the same as or the same as the test questions to be searched.
Optionally, after the test questions to be searched are searched in the high-frequency question bank, the high-frequency question bank is updated in time according to the number of times of searching the same test question in the high-frequency question bank.
Step S105: and receiving and displaying the problem solving result fed back by the server and corresponding to the matched test question to be searched.
And the number of the problem solving results is less than or equal to the number of the test problems to be searched. It can be understood that, after the secondary search is performed according to the method in step S104, if the test questions matched with the test questions to be searched are not searched in the topic sea within the preset time period, the number of the answer results corresponding to the currently matched test questions to be searched, which are fed back by the server, will be smaller than the number of the test questions to be searched.
Optionally, after receiving the test questions to be searched selected from the picture frame, the server corrects the content to reduce the probability that the test questions cannot be searched and matched with the test questions due to errors of the test questions.
Optionally, the search result fed back by the server may include: the correct answers of the test questions to be searched and/or the solution thinking of the test questions to be searched. In order to inspire students to think, after the test questions matched with the test questions to be searched are found, before the correct answers of the test questions to be searched are sent, the solution thought of the test questions to be searched can be sent to the users firstly, so that the users can try to answer the test questions firstly after obtaining the solution thought, after the users finish answering the test questions to be searched according to the solution thought of the test questions to be searched sent by the server or after obtaining the solution thought of the test questions to be searched, the users still have no trouble, and then the correct answers of the test questions to be searched are sent to the users.
Optionally, if the user can try to answer after obtaining the solution thought of the test question to be searched, after sending the correct answer of the test question to be searched to the user, the final answer condition of the user is counted, and the user can check the answer condition conveniently on the display interface of the preset APP.
As can be seen from the above, in the embodiment of the present invention, at least one text box is obtained by framing and selecting the text portion in the photo containing the test question to be searched according to a first preset condition, so that the area and the center point coordinate corresponding to each text box can be obtained; clustering the coordinates of each central point through the area of each text box and a second preset condition to obtain the complete test question to be searched; the complete part of the test questions to be searched can be further determined through two frame selections, and each complete test question can be used as an independent search object to be searched, so that the test questions to be searched can be identified more easily, the accuracy of the search questions is effectively improved, and the method has high usability and practicability.
