Referring to fig. 1, an embodiment of the present invention provides a flowchart of a method for automatically generating a print file.

And step S110, displaying a data analysis diagram of one or more objects on the current interface through a two-dimensional coordinate system.

In the scheme, the printer client or the server can store all printed files of the user, perform statistical analysis on the content in the files, and establish a relationship map among a plurality of objects and a database corresponding to each object. The object may be any object having individual characteristics, such as a human, a plant, an animal, a commodity, a school, and the like, among others. For example, in a teaching scene, the printed file includes test paper of each subject of each student, so that a relationship map between objects (students, class, grade, subject, school, area) and data related to examinations corresponding to the objects can be established; in a company scenario, the printed document includes the production process and sales condition of each commodity, so that a relationship map between objects (commodity, sales time, sales area, company) and production process and sales related data corresponding to each object can be established.

In this step, keywords of a plurality of analysis angles, such as "examination score distribution at the end of each shift of XX grade", "subject score average score of XX grade", "sales volume of XX company X in each quarter" and the like, may be displayed on the printer client, so that the user may select a desired analysis dimension, and based on the selection of the user, a data analysis graph of one or more objects related to the keywords at the analysis angle is displayed through a two-dimensional coordinate system. The object is determined based on the keywords under the analysis angle, and if the keywords are 'test score distribution at the end of each class in the XX grade', the object comprises a plurality of-classes in the XX grade; if the keyword is "sales volume for each quarter of the XX company X goods", the object includes one-XX company X goods.

Step S120, in response to a print instruction for the target section in the data analysis diagram, determining a target data type and a target data section included in the target section.

Specifically, when the user wants to analyze a detailed text corresponding to a certain part of data in the graph. For example, when viewing the data analysis graph of "XX-grade examination score distribution at end of each class", the user may want to know the name of a student, wrong question subject, ordinary test score, etc. with scores in the interval of 60-70; in viewing the "sales volume per quarter of XX company X goods" data analysis chart, the user may want to know the production process, return situation, and the like of the quarter X goods. Therefore, the user can frame data to be known in the data analysis diagram, and obtain target sections (abscissa sections and ordinate sections) from the rectangular frame to be framed.

In general, the data category may be determined based on the coordinate title in which the data is located. For example, if the ordinate title is a score, the data category of the ordinate data is the score, and if the abscissa title is a class, the data category of the abscissa data is the class. In this step, the data type of the target data is determined according to the abscissa title and the ordinate title, and the abscissa interval or the ordinate interval corresponding to the target data is selected as the target data interval. The target data is a detailed text which the user wants to know the data, so that the data which the user wants to know can be determined by analyzing the abscissa title, the ordinate title and the keywords of the data analysis chart.

Preferably, the target data category can be determined by the following scheme:

determining a first data type of a horizontal coordinate corresponding to the target interval and a second data type of a vertical coordinate corresponding to the target interval; and selecting the target data type from the first data type and the second data type according to the range of the target interval corresponding to the horizontal coordinate and the vertical coordinate respectively.

Specifically, the interval range includes a full interval range and a partial interval range, and if the user selects the full interval range on the abscissa, the ordinate selects the partial interval range, which indicates that the user wants to know the detailed text of the target data corresponding to the ordinate partial interval in the full interval range on the abscissa.

In the previous example, the vertical coordinate corresponding to the rectangular frame selected by the user is the score, so that the second data category is the score, and the corresponding interval range is 60-70 scores; the abscissa is a class, so the first data category is a class, and the range of the abscissa is a whole class because the user wants to know the names of students whose whole class scores are in the range of 60-70, wrong subjects, ordinary test scores, and the like. That is, the user wants to know the names of students with scores ranging from 60 to 70 in the whole grade range, wrong questions, ordinary test results, and the like, and therefore the data type of the target data is the score.

Further, the vertical coordinate corresponding to the rectangular frame selected by the user is the sales volume, so that the second data category is the sales volume, and the corresponding interval range is all; the abscissa is each quarter, so the first data class is time and the corresponding interval range is the first quarter. That is, the user wants to know the production process, return condition, etc. of all the sold X goods in the first quarter, and therefore the data type of the target data is time.

Step S130, obtaining target file attribute information corresponding to the target data type based on the mapping relationship between the data type and the file attribute information.

Before executing the step, a mapping relation between the data types and the file attribute information is established in advance according to the database corresponding to each object, namely, the file attribute information of the text associated with each data type is determined by combing and analyzing the printing file content of each object, and the mapping relation between the two is established. The mapping includes one-to-one and one-to-many. For example, the data type "score" has a mapping relationship with the file attribute information "student name", "wrong question", "school", and the data type "time" has a mapping relationship with the file attribute information "commodity X production process", "commodity X return rate", "commodity X stock".

Preferably, if the target file attribute information corresponding to the target data type includes multiple types, the multiple types of target file attribute information are displayed at a preset position of the data analysis diagram for selection by a user.

Specifically, the user may not need to print the text under the multiple target file attribute information corresponding to the target data category, so that the keywords of the multiple target file attribute information may be displayed in the form of a pop-up window or a bubble at the preset position of the data analysis diagram, so that the user may select the final target file information that the user wants to print, and then execute step S140.

Step S140, extracting a target text in the target data interval corresponding to the target file attribute information from the index file associated with the object, and generating a print file according to the target text.

Specifically, in the database corresponding to each object, each text content corresponding to the object is labeled with the corresponding file attribute information, and an index file corresponding to the object is generated.

In this step, according to the determined attribute information of the target file, the candidate text in the target data interval is searched in the index file corresponding to the object, and the target text corresponding to the attribute information of the target file is extracted from the candidate text. Furthermore, the target text may have a rereaded text (such as wrong title, manufacturing process, etc.), so the target document may be typeset after being deduplicated, and a print document may be generated.

Preferably, the object may be decomposed into a plurality of sub-objects based on different dimensions (for example, the object class may be decomposed into a plurality of sub-object classes according to class dimensions and a plurality of sub-object students according to person dimensions, the object product may be decomposed into a plurality of types of sub-object products according to product dimensions and may be decomposed into products in each time period according to time dimensions), in order to improve the indexing efficiency, the index file may be divided based on any dimension or any several dimensions corresponding to the object, and each dimension includes the index file corresponding to a plurality of sub-objects. That is, the index file of the object grade can be split into index files of a plurality of classes or index files of a plurality of students, and the index file of the object commodity can be split into index files of various types of commodities or index files of commodities in various time periods.

On the basis, the target index file can be determined firstly in the step through the following method, and then the target text can be directly found from the target index file.

Determining a target dimension corresponding to the object in the data graph according to coordinate titles corresponding to the horizontal coordinate and the vertical coordinate respectively; and determining a target index file based on the sub-object identification under the target dimension included in the target interval.

Specifically, the target dimension corresponding to the object may be determined according to the coordinate titles corresponding to the abscissa and the ordinate, for example, if the abscissa is each class, the target dimension is a class dimension, and if the abscissa is each quarter, the target dimension is a time dimension. After the target dimension is determined, the corresponding sub-object identifier is found from the range of the horizontal coordinate interval or the range of the vertical coordinate interval of the target interval, and the index file of the sub-object represented by the sub-object identifier is determined as the target index file.

According to the method, the device, the electronic equipment and the storage medium for automatically generating the print file, provided by the embodiment of the invention, on one hand, the corresponding print file can be automatically generated based on the data analysis chart, so that the printing efficiency is improved, and the printing time is saved; in addition, the target texts forming the print file are determined according to the target attribute information corresponding to the index file and the data analysis graph, and the accuracy of the print file is ensured while the source of the data texts is diverged.

As some optional implementations of the embodiment of the present invention, the index file is a two-dimensional table obtained by extracting a key text from an uploaded file and/or a machine-readable card based on the object identifier and the file attribute information.

Specifically, the server can acquire and store a file uploaded by a user through a client, extract an object identifier from the file, and form a key text by using a keyword or a key phrase corresponding to each file attribute information, wherein if all or part of contents of the file correspond to certain file attribute information, a text link is generated by the contents, and the text link and the object identifier form the key text; further, the server may also obtain the machine-readable card scanned by the scanner, identify the object identifier in the machine-readable card and the filling information of each question in the answering area, obtain a plurality of keywords or key phrases corresponding to the file attribute information based on the filling information, such as scores, wrong question numbers, and the like, combine the keywords or key phrases corresponding to the object identifier and the file attribute information into a key text, and also obtain the test question content corresponding to the wrong question numbers, generate text links, and combine them into the key text.

And determining the key text corresponding to each object identifier in each file attribute information to obtain the index file in the form of a two-dimensional table. As shown in table 1, the index file includes an object identification for each row of objects, and a text or text link for the object identification under each column of text attribute information.

TABLE 1

				Commercial product (Q1)	18342	Xx%	Doc1 Doc2 Doc3…
Commercial product (Q2)	25678	Yy%	Doc4 Doc5 Doc6…
				Commercial product (Q3)	19765	Aa %	Doc7 Doc8 Doc9…

As shown in fig. 2, the identification of the object in the machine readable card and the filling information of each topic in the answering area are realized by the following scheme:

step S210, obtaining a gray picture obtained by reading a card by a scanner, and positioning a plurality of preset identification blocks.

In this step, the square outline of the identification block is mainly searched in the gray-scale picture, and the square outline is used for positioning and determining the size of the machine-readable card. Generally, four corners of the machine-readable card are respectively provided with a black identification block for identification according to pixels and outlines, and in order to identify the front and back of the answer sheet, the size of the identification block on each corner can be different.

In practice, the machine readable card is printed, so that the black mark block has phenomena of 'black vertical lines passing through the mark block, white vertical lines passing through the mark block (lack of ink), and a large amount of ink lacking in the inner part and the edge of the mark block', and the like, thereby causing the mark block not to be correctly identified, or the width and the height of the mark block to be obviously too large or too small. In order to solve the problem, the scheme performs different treatments on the x direction and the y direction respectively. In the x direction, performing average filtering with the window length of 9 to reduce the influence of vertical lines as much as possible; in the y direction, a basic gaussian filter is made. Meanwhile, the square outline of the identification block is directly searched in smaller areas at four corners of the machine-readable card, so that the wrong selection of the square outline is avoided, and the identification rate of the identification block is improved.

And S220, zooming the gray-scale picture based on the identification block to obtain a target gray-scale picture, wherein the size of the target gray-scale picture is consistent with that of the machine-readable card template.

Specifically, the gray-scale picture is obtained by scanning, and is different from the size of the original answer sheet. Therefore, the gray scale picture is zoomed by taking the identification blocks as action points until the central point of each identification block in the gray scale picture coincides with the central point of the identification block corresponding to the identification block in the machine-readable card template, and the size of the obtained target gray scale picture is consistent with that of the machine-readable card template.

And step S230, determining the identification area of the target gray-scale picture and the answering area of each question through the machine-readable card template.

In this step, the machine-readable card template is covered in the target gray-scale picture, so as to obtain the identification area of the target gray-scale picture, the answering area of each question and the approximate area of each option in the answering area.

Step S240, aiming at the answering area of each question, determining the target option of each question according to the pixel gray value of each option, identifying the identification area, and determining the object identification of the machine-readable card.

In the step, on one hand, filling answers of each question in the answering area are identified, and on the other hand, object identification of the identification area is identified.

Specifically, for the answering area, the filled option has a plurality of black pixel points, and the gray value is high. Therefore, firstly, the gray map is subjected to binarization processing, the gray of the pixel point of which the gray value meets the preset condition is counted as a numerical value 1, and the gray of the pixel point of which the gray value does not meet the preset condition is counted as 0; secondly, a gray level average value can be calculated based on the gray level values of all pixels included in each option, before that, a gray level range corresponding to the filled target option is determined through a large amount of filling data, a gray level threshold value is generated based on the gray level range, and the option with the gray level average value falling into the gray level threshold value is used as the target option.

For the identification area, the object identification may be the name of the object or a string of characters representing the object. If the object mark of the mark area is handwritten or printed, recognizing the object mark by an optical character recognition technology to obtain the object mark; if the object identification of the identification area is filled characters, calculating the gray average value of all pixels in each option in each row or each column according to the scheme of the answering area to obtain the target option in each row or each column, and stringing together to obtain the target object identification.

Furthermore, as an optional implementation manner of the embodiment of the present invention, the inventor finds that, after printing and scanning, the identification block at 4 corners on the machine-readable card may not be kept as it is, and often has ink marks missing, so that a small amount of deviation occurs in the center point of the identification block, and there often occurs a deviation of several pixels in correspondence with the machine-readable card template that is not strictly stitched. Although the shift of several pixels is an order of magnitude small for the whole picture, it will have a relatively large effect for each fill-in option, and at this time, if the gray threshold is set to be relatively high, then the option which is easy to appear to be clearly filled in is not recognized; if the gray threshold is set to be low, then it is easy to see that there is no padding, but ABCD or 1234 in the selection, and the middle bracket itself, are also black, resulting in false positives as having padding.

Therefore, the following scheme can also be adopted to determine the target option: determining the central point of each option in the answering area according to the machine-readable card template, and obtaining a circumscribed rectangle of the central point based on the preset width and height; determining a filling area in the external rectangle, and eliminating target pixel points in the filling area which are matched with pixel points occupied by characters in options corresponding to the machine-readable card template; calculating the average gray value of the residual pixel points in the filling area after the target pixel points are removed; the target option is determined based on the average gray value.

Specifically, after the central point of each option is determined in the answering area according to the machine-readable card template, a circumscribed rectangle of the central point can be obtained based on the preset width and height of the options, and a plurality of pixels are respectively expanded outwards from four vertexes of the circumscribed rectangle to construct a slightly larger rectangular area. As mentioned above, there is expected and actual offset of a few pixels, and after enlarging a few pixels, it is guaranteed that the enlarged rectangular area will encompass the actual complete fill-in option. And then, drawing the outline of the actual filling area of the option according to the gray value of each pixel point in the rectangular area. The gray level is analyzed in the actual filling area of the option, and compared with the gray level analyzed in the rectangular area positioned by the machine-readable card template, the accuracy is greatly improved.

Further, for the calculation of the gray value in the actual filling area, it is decided whether the option is judged to be filled or not. In the scheme, firstly, the outer edge (such as a bracket part) of the option included in the actual filling area is removed to obtain an inner area, so that the influence of the gray value of the outer edge of the option is reduced; secondly, since the ABCD or 1234 in the selection is also black, there is some influence on the gray value determination, and meanwhile, the ABCD or 1234 has different influences on the average gray value due to different geometric shapes. Therefore, the sample pattern of the ABCD is obtained from the card reading template. For example, when the actual filling area comprises the letter A, based on the pixel point corresponding to the letter A in the machine-readable card template, removing the target pixel point matched with the actual filling area in the actual filling area to obtain the residual pixel points in the actual filling area; and then calculating the mean value of the gray values of the residual pixel points, thereby eliminating the influence of the ABCD or 1234 gray value on the average gray value as much as possible.
