It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, an embodiment of the present application provides a method for error printing, including:
s1, acquiring a title image;
s2, selecting wrong topic images from the topic images;
s3, identifying the wrong question image to obtain wrong question content;
s4, acquiring a corresponding reference answer according to the wrong question content;
and S5, printing the wrong question content and the reference answer according to a preset format.
In this embodiment, a printer with a palm-type implementation main body of the error question printing method is taken as an example for explanation, and a wifi module, a camera, a display screen and a thermal printer head are integrated on the printer, wherein the wifi module is used for connecting the printer to the internet through a wifi signal, the camera is used for collecting images, the display screen has a touch function and is used for displaying question contents and collecting control instructions input by a user, and the thermal printer head is used for printing error questions. In practice, a control system of a printer (hereinafter referred to as a printing system) captures a book such as a test paper or an exercise book in which wrong questions are recorded through a camera to obtain a question image, and at this time, the questions included in the question image may be composed of a mixture of correct questions and wrong questions, so that the printing system needs to screen the question image. Specifically, the printing system identifies error question stems by using preset error question features, identifies the separation among the questions according to the question segmentation marks, and identifies error regions corresponding to the error question stems from the question images after synthesis. The wrong-question feature mark comprises a cross mark x used by a teacher when reading the wrong question, or a wrong-question mark defined by the user, or the answer area of the question has no content, namely the answer area is blank; the title division mark includes a title serial number or a spacing distance between titles. And the printing system cuts the question image according to the selected image area to obtain an original wrong question image corresponding to the wrong question stem. Subsequently, the printing system adjusts parameters such as the size, the contrast and the like of the original error image according to preset conditions; and/or adding the annotations input by the user to the original wrong question image according to the input instruction of the user, and editing to obtain the wrong question image. The printing system identifies the wrong question image through a character identification technology to obtain wrong question content (the wrong question content at least comprises any one of characters, symbols and drawings). The wrong question content comprises one or more wrong question stems, the reference answers comprise reference sub-answers corresponding to the wrong question stems respectively, and the method for acquiring the reference sub-answers by the printing system is the same. Specifically, the printing system firstly screens out at least one keyword from the wrong question stem, and then obtains an original reference question with the similarity greater than a similarity threshold value with the wrong question stem from the Internet or a pre-associated question bank according to the keyword. Then, the printing system judges whether the number of the titles of the original reference titles searched at the current time is larger than a first number threshold, and if the number of the titles of the original reference titles is larger than the first number threshold, the printing system further screens out key characters and/or title drawings from wrong title stems. And then, taking the key characters and/or the topic drawings as comparison standards, screening an original reference topic with the highest similarity with the wrong topic stem from all the original reference topics as a reference topic, and loading the answer of the reference topic to obtain a reference sub-answer corresponding to the wrong topic stem. And summarizing the reference sub-answers of the wrong question stems to obtain the reference answers of the wrong question stems. The printing system displays the wrong question content and the reference answers on a display screen according to a preset format, and after the user confirms the wrong question content and the reference answers, the wrong question content and the reference answers are printed through a thermal printer head to form a wrong question set. Specifically, the printing system respectively fills each wrong question stem in the wrong question content into a pre-planned question area, and then respectively fills each reference sub-answer into an answer area below the corresponding wrong question stem, so that the wrong question content and the reference answers are distributed according to a preset layout, the attractiveness and regularity after printing are met, and the user can conveniently learn.
In the embodiment, the user only needs to use the camera device of the system to collect the question images, the system can automatically screen the wrong question content according to the question images, acquire the corresponding reference answers, and finally print the wrong question content and the reference answers in an associated manner to form a wrong question set.
Further, the step of selecting a wrong topic image from the topic images includes:
s201, identifying an image area corresponding to an error question stem from the question image according to a preset error question feature mark and a preset question segmentation mark;
s202, cutting the theme image according to the image area to obtain an original wrong theme image;
and S203, editing the original wrong question image according to an input instruction and/or a preset condition to obtain the wrong question image.
In this embodiment, the printing system stores preset wrong-question feature marks and question segmentation marks, where the wrong-question feature marks include a cross mark "x" used by a teacher when reading the wrong question, or a wrong-question mark defined by the user (for example, a serial number of the wrong question is circled), or a question area of the question has no content, that is, the question area is blank; the question segmentation mark comprises a question serial number or the size of the interval distance between questions (a blank area for filling answers generally exists between a question stem and the question stem, so the interval distance between the question stem and the question stem is far larger than the interval distance between every two lines of characters in the same question stem). The printing system firstly separates the areas corresponding to the topics contained in the topic image according to the topic segmentation marks, and then identifies the image area corresponding to the error topic from the separated topic image according to the error topic feature marks. And the printing system cuts the partial image corresponding to the image area of the wrong question stem in the question image to obtain the original wrong question image. The printing system correspondingly edits picture parameters such as the picture size, the brightness, the contrast, the saturation and the like of the original error image according to preset conditions so as to ensure that the edited secondary error image can be printed clearly. The printing system outputs the secondary wrong question image edited according to the preset conditions to a display interface for displaying so that the user can further edit the secondary wrong question image according to the requirement of the user. The user can label, scribble, etc. the wrong question stem according to self needs, and after receiving the user's input instruction (the input instruction includes label information and label area), the printing system labels the label information on the secondary wrong question image in the position corresponding to the label area, obtains the wrong question image that finally needs to print.
Further, the preset condition includes a picture parameter, the input instruction includes label information and a label area, and the step of editing the original wrong-question image according to the input instruction and/or the preset condition to obtain the wrong-question image includes:
s20301, editing the original wrong question image according to the picture parameters to obtain a secondary wrong question image;
s20302, adding the labeling information to the position corresponding to the labeling area on the secondary wrong problem image to obtain the wrong problem image.
In this embodiment, the preset condition includes a picture parameter, and the input instruction of the user includes label information (the label information includes information such as label characters, patterns, symbols, and the like) and a label area. The printing system scales the original wrong question image according to the uniform picture size according to the picture parameters in the preset condition so as to meet the printing layout; and then, adjusting the zoomed original wrong problem image according to the parameters of uniform brightness, contrast, saturation and the like so as to ensure that the edited secondary wrong problem image can be printed clearly. And then, the printing system sequentially adds the label information to the position corresponding to the label area on the secondary wrong question image according to the input sequence of the input instruction to generate a wrong question image, wherein the wrong question image is the content of the wrong question stem which needs to be printed finally, so that the requirements of personal learning and memory of a user are met.
Further, the wrong-question content includes one or more wrong-question stems, the reference answer includes a reference sub-answer of each wrong-question stem, and the step of obtaining the corresponding reference answer according to the wrong-question content includes:
s401, screening out at least one keyword from the wrong question stem;
s402, obtaining an original reference question with the similarity larger than a similarity threshold value with the wrong question stem according to the keyword;
s403, judging whether the number of the questions of the original reference questions is larger than a first number threshold value;
s404, if the number of the original reference questions is larger than a first number threshold, screening out key characters and/or question drawings from the wrong question stem;
s405, according to the key characters and/or the topic drawings, screening an original reference topic with the highest similarity with the wrong topic stem from all the original reference topics as a reference topic;
s406: outputting the reference questions to a display interface for a user to confirm whether the reference questions are screened correctly;
s407, if the user confirms that the reference question is screened correctly, the answer of the reference question is loaded to obtain the reference sub-answer.
In this embodiment, the wrong-question content includes one or more wrong-question stems, and the corresponding obtained reference answers also include the sub-reference answers of each wrong-question stem. The printing system stores a pre-constructed keyword library, and the keyword library contains keywords commonly used by topics corresponding to each subject type, such as 'acceleration and gravity' in a physical subject, 'xx year, xx month and xx day' in a historical subject, and 'DNA and cells' in a biological subject. The printing system searches the wrong question stem according to the keyword library, and screens out at least one keyword corresponding to the keyword library from the wrong question stem as a reference of the current search question. The printing system is connected with the Internet or pre-associated topics through a wifi module, then topic searching is carried out according to the selected keywords, and original parameter topics with the similarity degree larger than the similarity threshold value with wrong topic stems are screened. The similarity between the original reference question and the wrong question stem is comprehensively obtained according to the same number of the keywords and the occurrence frequency of the keywords, for example, 5 keywords are selected at the current time, the original reference question A comprises 4 keywords, and the initial similarity is 80%; the original reference topic B contains 3 keywords with an initial similarity of 60%. The number of occurrences of the keyword determines a similarity coefficient between the two (the specific value of the similarity coefficient may be defined according to actual conditions, and is not specifically defined herein), for example, if the number of occurrences of the keyword "acceleration" in the original reference topic a is 5, the corresponding similarity coefficient is 1, and if the number of occurrences of the keyword "acceleration" in the original reference topic B is 4, the corresponding similarity coefficient is 0.8. After the two are combined, the final similarity of the original reference topic A is 80%, and the final similarity of the original reference topic B is 48%. The printing system judges whether the number of the original reference titles selected at the current time is larger than a first number threshold, and if so, further screening is needed. Therefore, the printing system screens out key characters (such as physical symbols and chemical symbols) and/or topic drawings from the wrong topic stem, and then screens out one original reference topic containing the key characters and/or the topic drawings from each original reference topic as a reference topic with the highest similarity with the wrong topic stem. The printing system outputs the reference question with the highest similarity with the wrong question stem to a display interface of the printing equipment for displaying so that a user can confirm whether the reference question is screened correctly, namely whether the reference question is the same as the wrong question stem. And if the user confirms that the reference questions screened by the printing system are the same as the wrong question stems, inputting a correct screening instruction or clicking a correct screening option on a display interface. And after receiving an instruction confirmed by the user to be correct, the printing system automatically loads the answer of the reference question to obtain a reference sub-answer corresponding to the wrong question stem. And the printing system sequentially acquires the reference sub-answers corresponding to the wrong question stems according to the rules, and the reference sub-answers are summarized to obtain the total reference answers corresponding to the wrong question contents.
Further, the step of printing the wrong-question content and the reference answer according to a preset format includes:
s501, judging whether the wrong number of the wrong question stems is larger than a second number threshold value or not;
s502, if the wrong number of the wrong question stems is larger than a second number threshold, judging whether the wrong question stems belong to the same subject;
s503, if the wrong question stems do not belong to the same subject, dividing a printing area on a printing layout page according to the subject types corresponding to the wrong question stems;
s504, filling each wrong question stem and the corresponding reference sub-answer into the printing area of the corresponding subject type respectively, and printing,
in this embodiment, the printing system determines whether the number of wrong questions of the wrong question stem is greater than a second number threshold, and if the number of wrong questions is greater than the second number threshold, each wrong question stem needs to be separately printed according to the respective subject type, so as to avoid that the wrong questions of different subject types are mixed on the same page, and the knowledge points are disordered, which is not beneficial to review and memory of the user. The printing system identifies the discipline types corresponding to the error question stems according to the keywords and/or the key characters of the error question stems, and then judges whether the error question stems belong to the same discipline according to the discipline types. If part or all of the error question stems do not belong to the same subject, dividing the printing area on the printing layout page according to the number of the subject types, for example, if the current error question content contains 3 different subject types, the printing layout page needs to be divided into 3 printing areas, and the printing areas are separated by a separation line or a blank area with a larger space. Then, the printing system fills each wrong question stem and each corresponding reference sub-answer into the printing area of the corresponding subject type respectively, and prints the wrong question stem and the corresponding reference sub-answer through a thermal printer head to form a wrong question set. According to the embodiment, the printing areas are divided according to the corresponding subject types of the wrong question stems and the reference sub-answers, so that the printed wrong questions are concentrated, the knowledge points are distributed regularly, when a user uses the wrong question set to learn, the questions of the subject types needing learning can be quickly found, the knowledge points of different subject types cannot be mixed, and the learning efficiency of the user is effectively improved.
Further, a subject key information set is respectively and correspondingly established for each subject type, the subject key information set is a set of nouns and symbols preset by the subject type, and the step of judging whether each wrong-subject stem belongs to the same subject includes:
s50201, matching the key words and/or key characters of the wrong question stems with the key information sets of the disciplines respectively to obtain discipline types corresponding to the wrong question stems respectively;
s50202, judging whether the subject types corresponding to the wrong question stems are the same or not;
