On one hand, the cooperation of the terminal 110 and the server 120 is adopted to realize the automatic check of the response result, manual check is not needed, and the check efficiency of the response result and the accuracy of the correct and wrong information are improved; on the other hand, the terminal 110 marks the correct and incorrect information, so that the correct and incorrect information is very visual and clear.
Embodiments of the various steps involved in the interaction flow are described in detail below.
In step 210, the test question picture obtained by the terminal 110 may be a picture obtained by shooting the test question through the terminal 110 by the user at present; or a specific test question picture selected by the user from an existing test question picture list. That is, when the terminal 110 prompts to upload the test question pictures, the user may select to take the test question pictures in real time, or select to specify the specified test question pictures from the test question pictures taken in advance. The user may be a parent, a student, or a teacher, among others.
The test question picture comprises a mathematical formula question and an answering result to be checked. The test question picture may include only one test question or may include a plurality of test questions. For example, referring to fig. 3, a schematic diagram of a test question picture (only a part of the mathematical expression questions are shown), the test question picture shown in fig. 3 includes a plurality of test questions, and in the test question "49 +34 equals 83", the mathematical expression "49 +34 equals" and the answer result is "83". In the test question "1 m-20cm ═ 80 cm", the calculation formula was "1 m-20cm ═ and the answer was" 80cm ".
In step 220, the terminal 110 sends the test question picture to the server 120; in step 230, the server 120 receives the test question picture sent by the terminal 110, identifies the test question picture, and extracts a mathematical formula question; and determining the position information of the mathematical formula questions in the test question picture.
For the server 120, a plurality of picture recognition technologies may be used to recognize the test question picture. As an alternative, the server 120 uses an OCR (Optical Character Recognition) technology to recognize the test question picture. For the test questions, they are usually printed on paper, so the characters on the test question picture are print characters. OCR technology can examine printed characters on paper, determine their shape by detecting dark and light patterns, and then translate the shape into computer text using character recognition methods, i.e., optically achieve recognition of the characters.
Of course, the test questions may not be printed on paper, or may be a test question picture generated by answering an electronic version of the test questions on the terminal 110, and in this case, other corresponding recognition techniques may be employed.
The server 120 may extract each character on the test question picture through various image recognition techniques, but there may be other unnecessary characters on the test question picture in addition to the mathematical arithmetic questions and the answering results. Therefore, on the server 120, a character filtering rule may be preset, and only those satisfying a specified character condition are determined as the extracted mathematical expression questions and answer results. Such as: the mathematical expression usually includes only letters, numbers and various symbols, but does not include Chinese characters. If some extracted character string includes Chinese characters and numbers, the character string does not belong to the mathematical formula problem.
Of course, in some possible embodiments, the mathematical formula problem may also be written in a chinese character writing manner, for example, "eight plus twenty-five equals" and the answer result is "thirty-three", which is not described herein again.
For the test questions, the test questions include mathematical formula questions and answer results, and therefore, after the test questions are extracted by the server 120, the test questions may be split based on a preset mathematical formula question bank or answer result identification information. Such as: the preset mathematical expression questions include a plurality of standard mathematical expressions, which have no specific numerical value and are only used for representing the rules of the mathematical expressions, such as: the standard mathematical formula is "a + b ═ which represents summing two numbers. And matching the character strings with the standard mathematical expressions in the mathematical expression question bank, wherein if the character strings corresponding to the standard mathematical expressions are matched, the character strings matched with the standard mathematical expressions are the mathematical expression questions. For another example: the character preceding the answer is usually a "symbol" which is used as the answer identification information, and after detecting the symbol in the character string, the character string preceding the symbol is a mathematical formula, and the character string following the symbol is the answer.
The server 120 may also split the mathematical expression questions and the answer results of the test questions by other implementable techniques, which are not limited in the embodiment of the present application.
The server 120 may also locate the coordinates of the mathematical expression questions during the identification process, that is, determine the position information of the mathematical expression questions in the test question picture. The position information is the pixel coordinate of the mathematical expression question relative to the test question picture, and the position of the mathematical expression question can be positioned through the pixel coordinate.
It is understood that if a plurality of mathematical expression questions are identified and extracted in step 230, the same processing is performed for each mathematical expression question. Such as: in step 240, the determined correct answer result is the correct answer result of each mathematical formula. For another example: in step 250, the correct and incorrect information and the mathematical expression questions also have a one-to-one correspondence relationship. For the sake of simplicity of the description, in the following description of the embodiments, the processing conditions of a single or a plurality of mathematical expressions are not particularly distinguished, and the processing logic of a single mathematical expression is taken as an example for description, and the processing logic of a plurality of mathematical expressions may be analogized and analogized.
In step 240, the server 120 determines the correct answer result corresponding to the mathematical formula. As an alternative embodiment, the steps include: converting the mathematical operation questions into mathematical operation questions in a mathematical code format; and inputting the converted mathematical operation questions into a preset detection model to obtain correct answer results corresponding to the mathematical operation questions.
In this embodiment, the server 120 stores a detection model trained based on a training data set, and the detection model may be a machine learning model or a model commonly used in the field of artificial intelligence, such as a neural network model. The training data set can be a plurality of mathematical operation questions in an existing question bank and answer results corresponding to the mathematical operation questions, and the answer results corresponding to the mathematical operation questions can be results calculated by a calculator or a computer; or may be the result of a calculation by an experienced teacher. Training an initial detection model by using a training data set, performing precision detection on the trained detection model, optimizing the detection model to obtain a final trained detection model, and storing the final trained detection model on the server 120, wherein the server 120 can directly determine a correct answer result of the mathematical operation formula based on the trained model.
In the embodiment of the present application, the data processed by the server 120 is not data in a direct formula format, such as: when training a model, data in a training data set needs to be converted into a mathematical code format and then input into an initial detection model. Similarly, when determining a correct answer result based on the trained detection model, the mathematical expression problem needs to be converted into a mathematical code format and then input into the trained detection model.
By way of example, for mathematical problems:
the corresponding mathematical code format is as follows: \ sqrt [3 ]]{ x _1^2+ x _2^2+ x _3^2+ x _4^2 }; for mathematical formula questions
The corresponding mathematical code format is as follows: 1+ \ left (\ frac {1} {1-x ^2} \ right) ^ 3.
As another alternative, the server 120 itself is a large computer with computing capability, or is equipped with a computing module with functions similar to those of a calculator, so that if the mathematical computation is within the computing capability of the computing module, the server 120 can also determine the correct answer result through the computing module.
In step 250, the server 120 compares the answer result to be verified with the correct answer result to obtain a comparison result; and generating the correct and wrong information according to the comparison result and the mathematical formula question.
In the step, if the comparison result is that the answer result to be tested is consistent with the correct answer result, the answer result to be tested is marked as correct in the error-correcting information; and if the comparison result is that the answer result to be verified is not consistent with the correct answer result, marking the answer result to be verified as an error. Therefore, for the generated correct and incorrect information, whether the response result to be verified is correct or not can be represented.
When the correct and incorrect information is generated, the mathematical formula question corresponds to the identifier for representing whether the answering result is correct, such as: the positive and negative information is: mathematical formula A-correct; mathematical formula B-error; or other implementable forms, and are not limited in the embodiments of the present application.
In step 260, the server 120 generates a verification result according to the error information and the position information. The server 120 may add location information based on the error information. Such as: the check result is: mathematical formula a-correct-pixel coordinate 1; mathematical formula B-error-pixel coordinate 2; or other implementable forms, and are not limited in the embodiments of the present application. It is understood that, since the mathematical expression includes more than one character, each character may correspond to one pixel coordinate, and thus, the pixel coordinate may be a pixel coordinate range, or a pixel coordinate set composed of a plurality of pixel coordinates.
After the server 120 generates the verification result, the verification result is fed back to the terminal 110, and in step 270, the terminal 110 receives the verification result returned by the server 120 and marks the error correction information on the test question picture according to the position information.
As an alternative embodiment, the process of marking the correct and incorrect information includes: determining the position of the mathematical formula questions on the test question picture according to the position information; determining the marking position of the correct and wrong information according to the position of the mathematical formula questions on the test question picture; and marking correct and incorrect information at the marked position.
In this embodiment, the determination of the position of the mathematical expression problem is performed based on the pixel coordinates in the position information, and then the labeling position is determined. When the marking position is determined, the marking position can be determined according to a preset rule. Such as: the marking positions of the correct and wrong information are preset as follows: the back of the answer result, the lower part of the answer result and the position of the answer result; or the first character of the mathematical expression, etc., are not limited in the embodiments of the present application.
According to a preset rule, the pixel coordinates corresponding to the labeling position can be determined, for example: and assuming that a preset rule is behind the answer result, adding a preset value to the abscissa on the basis of the pixel coordinate corresponding to the answer result, keeping the ordinate unchanged, obtaining the pixel coordinate which is the pixel coordinate corresponding to the marking position, and then marking the correct and wrong information at the corresponding pixel coordinate. The various rules involved may be defined in advance according to an actual application scenario, or configured by the user on the terminal 110, which may be understood as a setting function of the application program.
As described in the foregoing embodiment, the correctness information can be used to characterize whether the calculation result is correct, and as an optional implementation, the marking the correctness information at the marking position includes: if the answer result is determined to be correct according to the correct and incorrect information, rendering a preset first symbol mark at the marking position; and if the answer result is determined to be wrong according to the correct and wrong information, rendering a preset second symbol mark at the marking position.
In this embodiment, the two results are represented by two different symbolic identifications, wherein the first symbolic identification may be, for example: "√ root"; the second symbol identification may be, for example: "×", ". smallcircle", etc. The first symbol mark and the second symbol mark may also be different in expression form, such as: the first symbol is identified as green and the second symbol is identified as red.
It is understood that the implementation manners of the first symbol identifier and the second symbol identifier may be flexibly set according to an actual application scenario, or a user configures through a setting function of an application program, which is merely an exemplary example in the embodiment of the present application and does not constitute a limitation to the implementation manners of the embodiment of the present application.
When the terminal 110 renders, the rendering position is known, the rendering object is known, and the rendering of the identifier at the corresponding position of the test question picture can be realized by directly using the built-in rendering engine. After the rendering of the corresponding mark is completed, the test question picture is a reviewed test question picture representing that the test question picture is reviewed.
After the identification of the test question picture is completed, the terminal 110 presents the read test question picture identified with the correct and incorrect information in step 280. For example, please refer to fig. 4, which is a schematic diagram of a picture of a subject being examined, and it can be seen that the correct answer result and the incorrect answer result have corresponding correct or incorrect identifiers, respectively.
It is understood that after the terminal 110 displays the picture of the subject being read, the user can perform various operations on the picture of the subject being read, such as: operations such as zooming in and zooming out, which are functions that can be realized by the conventional terminal 110, are not described in detail in the embodiments of the present application.
In the embodiment of the present application, the second symbol identifier may be further set as a clickable symbol identifier, and when the user clicks the second symbol identifier, a corresponding request may be further triggered. Therefore, as an optional implementation, after step 280, the interaction flow further includes: the terminal 110 generates an analysis request when receiving a preset operation for the second symbol identifier; the resolution request is sent to the server 120. Wherein the second symbol mark represents the wrong mark of the answering result; the preset operation may be various selection operations such as clicking. When the user performs corresponding selection operation on the identifier, a request for analyzing the wrong answer result may be triggered. Thus, a resolution request may be understood as a request to obtain a resolution of the wrong question.
For the server 120, after receiving the parsing request, obtaining a preset error resolution library; the wrong question analysis library comprises a plurality of mathematical formula questions and wrong question forms and analysis of the plurality of mathematical formula questions; determining error analysis corresponding to the answer result according to a preset error analysis library and the answer result; generating an analysis result corresponding to the analysis request according to the error analysis, the mathematical formula questions and the correct answer result; and feeding back the analysis result to the terminal 110.
In this embodiment, the server 120 is pre-installed with an error analysis library, which includes various mathematical equations, and error forms and analyses of the various mathematical equations. By way of example: assuming that the mathematical formula is entitled "62-36", the corresponding wrong formula may be: "62-36 ═ 36", the corresponding analysis of the error pattern is: the two digits are subtracted from the two digits without back-stepping (briefly described); there may also be: "62-36 ═ 2X", where the numerical value of "X" is from 0 to 9 except for 6, and the corresponding analysis of the error pattern is: addition and subtraction errors of single digit.
And matching the answer result with answer results in different error forms based on the error analysis library, and determining the analysis corresponding to the error form as the error analysis corresponding to the answer result if the answer result is matched with the corresponding error form.
After determining the error analysis corresponding to the answer result, the server 120 performs one-to-one correspondence between the error analysis, the mathematical formula questions and the correct answer result to generate an analysis result, and then feeds back the analysis result to the terminal 110. When feedback, the mathematical operation questions and the correct answer result can be in the mathematical code format. Wherein, the correct answer result can be understood as the reference answer corresponding to the mathematical formula question. Therefore, the correct answer result may be identified as the reference answer when the parsing result is generated.
When determining an error resolution based on the error resolution library, if a corresponding error resolution is not found, the server 120 may still generate a resolution result at this time. The analysis result at this time may include: mathematical questions, correct answers, and hints indicating no false resolution, such as: and (5) temporarily carrying out error analysis.
For the terminal 110, the parsing result fed back by the server 120 is received, and then the parsing result is displayed. In the above embodiment, the mathematical operation questions and the reference answers corresponding to the mathematical operation questions may be in a mathematical code format, so that the terminal 110 may convert the mathematical operation questions and the reference answers corresponding to the mathematical operation questions from the mathematical code format to a formula format first when displaying; and then displaying the mathematical operation questions converted into the formula format and the reference answers corresponding to the mathematical operation questions. The interconversion between the data code format and the formula format can be realized through a preset conversion rule.
For example, referring to fig. 5, an example diagram of an error analysis presentation interface provided in the embodiment of the present application shows that the error analysis includes a mathematical formula question and an answer result identified from a test question picture, an identification result corresponding to the mathematical formula question and the answer result, a reference answer corresponding to the mathematical formula question, and an error analysis of the answer result.
Other prompt information can be attached to the analysis of the wrong question, such as: in fig. 5, the display interface further includes prompt information for prompting the user to evaluate the error analysis, and the user may click the corresponding evaluation option to submit the evaluation result.
After the terminal 110 receives the evaluation result of the user, the evaluation result may be fed back to the server 120, and the server 120 may take corresponding optimization measures based on the evaluation result. Such as: optimizing the analysis in the wrong question analysis library in a manual inspection mode; optimizing the matching rules of the wrong question analysis library and the calculation result, and the like.

The terminal 110 performs result position matching based on the picture recognition result, and synthesizes the result position to the specified position of the correction mathematical formula question, specifically, if the answer result is correct, adds the corresponding tick mark (green); if the answer result is wrong, adding a corresponding circling mark (red); and carrying out corresponding result page display. If the parents/teachers/students click the red circle marks, the server 120 compares the recognition results with the reference answers and performs wrong question analysis; feeding back the recognition result, the reference answer and the wrong question analysis; the terminal 110 then performs presentation of a wrong-question-resolved page based on the recognition result, the reference answer, and the wrong-question resolution.
