Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail. In addition, in the description of the present application and the appended claims, the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and are not to be construed as indicating or implying relative importance.

At present, the shooting and question searching technology is mature, and is widely applied to electronic equipment such as mobile phones, learning machines, tablet computers, dictionary pens, learning desk lamps and the like. The electronic devices such as dictionary pens have a characteristic that when searching questions, the electronic devices need to be scanned for multiple times when scanning questions in multiple rows, and a question image is obtained by scanning each time. After the scanning is completed, the dictionary pen needs to preprocess and splice all the topic images obtained by the scanning, and then sends the spliced images to a topic searching server to obtain corresponding topic searching results. It can be seen that the overall process flow of the electronic device is lengthy during this process, which results in a slower response speed for the user.

Aiming at the problem, the embodiment of the application provides a method, a system, electronic equipment, a server and a storage medium for scanning and searching questions, which can improve the speed of the electronic equipment for responding to users during searching questions. For more specific technical implementation details of embodiments of the present application, please refer to various embodiments described below.

Referring to fig. 1, a scanning question searching system provided in an embodiment of the present application is shown, where the system includes an electronic device and a question searching server. The electronic device is a question searching terminal used by a user, and can be specifically a dictionary pen, a translation pen, a learning machine, a smart watch or a tablet computer. The question searching server is a remote device for providing question searching service, and communication connection can be established between the question searching server and the electronic device through a network and the like. In addition, the system shown in FIG. 1 may also include an OCR server that may interact with the search server during the scanning of the search questions to provide OCR recognition services. The embodiment of the application does not limit the specific device types of the electronic device, the question searching server and the OCR server of the system, and as for the specific working principle of the system, please refer to the method embodiment described below.

Referring to fig. 2, a method for searching questions by scanning according to an embodiment of the present application is shown, including:

201. in the process of scanning the topic page, the electronic equipment sends the topic image to the topic searching server every time a topic image is obtained by scanning;

when a user uses electronic equipment such as a dictionary pen to scan and search questions, the target part of the electronic equipment can be aligned with a certain question in a question page and start scanning, for example, the pen point part of the dictionary pen is aligned with and contacted with the question in the question page, and the scanning is started to obtain a corresponding question image. If the target question is a single-line question, the user only needs to scan once, and the electronic equipment sends a scanned question image to the question searching server. If the target questions are multi-line questions, the user needs to scan for a plurality of times in sequence, each time a question image is obtained by scanning, and each time the electronic equipment obtains a question image by scanning, the question image is sent to the question searching server so as to pre-process the question image in advance by the question searching server. For example, assuming that a plurality of lines of questions are scanned, the electronic device may send the question image 1 to the question searching server after scanning the first line of questions to obtain the question image 1, and the question searching server may start preprocessing for the question image 1 after receiving the question image 1, without waiting for the electronic device to scan to obtain all the question images and then starting preprocessing.

In one implementation manner of the embodiment of the present application, the electronic device sends the topic image to the topic searching server, including:

(1) Generating a unique topic identification;

(2) And associating the topic image with the topic identifier, and transmitting the associated topic image and the topic identifier to a topic searching server.

For the search server, it receives the topic images corresponding to different topics sent by different electronic devices, or receives the topic images corresponding to different topics sent by the same electronic device, and the same topic may also correspond to multiple topic images (such as multiple lines of topics). In order to facilitate the distinction of the search server, when the electronic device does not determine that the scanning process of a question is completed, a unique question mark can be generated, the mark is used for uniquely representing a question, each time a question image is obtained through scanning, the question image is associated with the mark, and the associated question image and the question mark are both sent to the search server. For example, for a topic a of 3 lines, 3 scans are required to obtain a topic image 1, a topic image 2 and a topic image 3, and after the topic image 1 is obtained by scanning, the electronic device associates the topic image 1 with the unique identifier of the topic a and sends the unique identifier to the topic search server, after the topic image 2 is obtained by scanning, associates the topic image 2 with the unique identifier of the topic a and sends the unique identifier to the topic search server, and after the topic image 3 is obtained by scanning, associates the topic image 3 with the unique identifier of the topic a and sends the unique identifier to the topic search server. The electronic device then determines that the scanning process for topic a has been completed, regenerates another topic identification when the next topic image is scanned subsequently, processes it in the same manner, and so on.

202. The question searching server preprocesses the question image after receiving one question image sent by the electronic equipment;

and when the question searching server receives a question image sent by the electronic equipment, carrying out corresponding preprocessing operation on the question image. The preprocessing operations herein may include, but are not limited to: image correction, image beautification, image cropping, image denoising, image compression, removal of handwriting from an image, and the like. By preprocessing the topic image, the quality of the topic image and the accuracy of identifying the content of the topic image can be improved, and the accuracy of searching the topic is further improved.

In an implementation manner of the embodiment of the present application, after preprocessing the topic image, the topic searching server further includes:

and sending the preprocessed topic image to an OCR server to instruct the OCR server to perform OCR recognition on the topic image, and returning an OCR recognition result of the topic image.

The method for searching the questions by the question searching server can comprise two modes, wherein the first mode is to search the questions based on the images, and the method only needs to splice all received question images corresponding to the same question, and search the questions according to the spliced images. The second way is to search questions based on text, which requires OCR recognition of the question image to obtain the corresponding question text, and then search questions based on the question text. If the first mode is adopted, the problem searching server does not need to interact with the OCR server, and the problem searching process can be completed automatically. If the second mode is adopted, the question searching server needs to interact with the OCR server, and OCR recognition is carried out on the question image through the OCR server, so that corresponding question text is obtained. Specifically, each time the question searching server completes a preprocessing process of a question image, the question image can be sent to the OCR server, OCR recognition is performed on the question image by the OCR server to obtain an OCR recognition result, namely a corresponding question text, and then the OCR recognition result is returned to the question searching server. The question searching server can store data such as each preprocessed question image, an OCR recognition result corresponding to each preprocessed question image, a question identifier associated with the question image and the like through a database.

203. If the electronic equipment determines that the scanning process of a question is completed, sending a question searching instruction to a question searching server;

each time the electronic device completes a scan, a determination may be made as to whether a process of scanning a topic has been completed. If the scanning process of one question is not completed, the judgment is carried out again after the next scanning is waited until the scanning process of one question is determined to be completed. If the scanning process of the title is determined to be completed, the electronic equipment sends a title searching instruction to the title searching server, wherein the title searching instruction is used for instructing the title searching server to start a title searching operation and returning a title searching result.

In one implementation of an embodiment of the present application, an electronic device determines whether a process of scanning a topic has been completed by:

(1) Detecting the duration of leaving the target part of the electronic equipment from the question page;

(2) If the duration exceeds the set threshold, determining that the scanning process of a title is completed.

After completing one scan, the user usually lifts up the electronic device, if one question is not scanned, the user needs to start another line to continue scanning, and the next scan can be performed in a short time; conversely, if a topic has been scanned, the user will typically not proceed to the next scan for a short period of time. Taking this feature into consideration, taking an electronic device such as a dictionary pen as an example, it is possible to determine whether a scanning process of a question has been completed by detecting a duration of a target portion (e.g., a pen tip) of the dictionary pen leaving a page of the question. Specifically, when the pen point of the dictionary pen is detected to leave the question page, the user is shown to lift the pen point, the duration is counted at the moment, if the pen point contacts the question page again in a short time (for example, within 1 s), the second scanning is started, the scanning process of a question is determined not to be completed, and after the second scanning of the user is waited to complete and the pen is lifted, judgment is performed again. If the pen point does not contact the question page again in a short time, namely the duration of pen lifting by the user exceeds a set threshold value, the second scanning is not started in a short time by the user, so that the scanning process of a question can be considered to be finished currently.

In addition to the above-mentioned method of detecting the duration, the electronic device may determine whether the scanning process of a question has been completed in various other ways, for example, the electronic device may set a button, the user may manually press the button after scanning a question, and the electronic device may determine that the scanning process of a question has been completed after detecting that the button is pressed. For another example, the electronic device may obtain the topic image obtained by the current scan, perform text recognition on the topic image to obtain the topic text, and if it is detected that the end of the topic text has the text. "or"? "etc., it is determined that the scanning process of a title has been completed.

In one implementation manner of the embodiment of the present application, sending a question searching instruction to a question searching server includes:

and sending a question searching instruction carrying the question mark to the question searching server so as to instruct the question searching server to search questions based on all the preprocessed question images associated with the question mark.

When the electronic equipment sends the question searching instruction to the question searching server, the question searching instruction can carry the question mark corresponding to the current question. According to the content description about the topic identification, it can be known that all topic images corresponding to each topic are associated with the same topic identification, so that after receiving a topic searching instruction, the topic searching server can search all the topic images associated with the topic identification after preprocessing from a database according to the topic identification carried by the topic searching instruction, and complete topic searching based on the topic images.

204. And if the question searching server receives a question searching instruction sent by the electronic equipment, searching questions based on all the preprocessed question images, and returning a question searching result to the electronic equipment.

After receiving a question searching instruction sent by the electronic equipment, the question searching server starts a question searching operation, at the moment, all question images corresponding to the current questions stored after preprocessing can be searched from the database, the question searching is completed in a mode of searching the questions based on the images or in a mode of searching the questions based on texts, and therefore corresponding question searching results are obtained, and the question searching results are returned to the electronic equipment.

In an implementation manner of the embodiment of the present application, the question searching server performs question searching based on all the preprocessed question images, including:

(1) Splicing the OCR recognition results of all the preprocessed topic images into a target text;

(2) And searching the questions according to the target text.

If a text-based question searching mode is adopted, the question searching server can send the preprocessed question images to the OCR server before receiving the question searching instruction, and after the OCR server carries out OCR recognition on the question images and returns OCR recognition results, the question searching server can store the OCR recognition results of each question image. After receiving the question searching instruction carrying the question mark, the question searching server can find all the question images corresponding to the current question and preprocessed according to the question mark, acquire OCR recognition results of the question images, and splice the OCR recognition results according to the scanning sequence of the question images in sequence, so that a target text is obtained. And finally, searching the questions by the question searching server according to the target text, thereby obtaining a corresponding question searching result.

In another implementation manner of the embodiment of the present application, the question searching server performs question searching based on all the preprocessed question images, including:

(1) Splicing all the preprocessed question images into a target image;

(2) And searching questions according to the target image.

If the mode of searching questions based on the images is adopted, after receiving a question searching instruction carrying a question mark, the question searching server can find all the question images which correspond to the current question and are preprocessed according to the question mark, and then the question images are spliced in sequence according to the scanning sequence, so that a target image is obtained. And finally, searching the questions by the question searching server according to the target image, thereby obtaining a corresponding question searching result.

For the technical scheme of the embodiment of the application, in the process of scanning the questions, the electronic equipment sends a question image to the question searching server every time when scanning one question image, and the question searching server can perform corresponding preprocessing operations, such as image correction, image denoising, image compression and the like, on the question image every time the question searching server receives one question image; and if the electronic equipment determines that the scanning process of the questions is finished, a question searching instruction is sent to the question searching server, the question searching server can search the questions based on all the preprocessed question images after receiving the question searching instruction, and a question searching result is returned to the electronic equipment. Through the arrangement, in the process of scanning the questions by the electronic equipment, the question searching server can preprocess the received question images in advance, and after the electronic equipment finishes scanning, the electronic equipment can wait for obtaining the corresponding question searching result by sending a question searching instruction to the question searching server without executing long processing flows such as image preprocessing, image splicing and the like, so that the speed of responding to a user when the electronic equipment searches questions can be improved.

In order to facilitate understanding of the method for scanning and searching questions provided by the embodiment of the application, the following lists practical application scenarios. Fig. 3 is a schematic operation flow chart of the method for scanning and searching questions in the practical application scenario according to the embodiment of the present application. In fig. 3, 3 devices including a dictionary pen, a question searching server, and an OCR server are included. Firstly, a user scans a question by using a dictionary pen, and when the user lifts the pen every time, the dictionary pen can count the duration of lifting the pen, and whether the scanning process of the question is completed is judged according to the duration. If the duration is short, that is, the user performs the second scanning in a short time, it is determined that the scanning process of a question is not completed, at this time, the dictionary pen correlates the question image obtained by the current scanning with the identification of the current question and sends the question image to the question searching server, and returns to the step of the user for scanning the question, and waits for the next time of lifting the user to repeat the same judging process, and the operations in the two aspects can be performed asynchronously. And after receiving the topic image, the topic searching server can preprocess the topic image. In addition, the question searching server can also send the preprocessed question images to the OCR server, the OCR server carries out OCR recognition processing on the question images to obtain corresponding OCR recognition results, the OCR recognition results are returned to the question searching server, and the question searching server can store the OCR recognition results of each question image in the database. If the duration of pen lifting by the user is long enough, the dictionary pen determines that the scanning process of a question is completed, a question searching instruction carrying the current question mark is generated at the moment, and the question searching instruction is sent to the question searching server. After receiving the question searching instruction, the question searching server can find OCR recognition results of all corresponding question images from the database according to the current question mark, splice the OCR recognition results into a question text, finish the question searching according to the question text, and return the question searching result to the dictionary pen.

In summary, in the scenario of searching questions in multi-line scanning, the embodiment of the application can send the scanned question image to the question searching server for preprocessing in advance, and after the user scans a question, the electronic device does not need to execute long processing flows such as image preprocessing, image splicing and the like, so that the speed of responding to the user can be effectively improved.
