Fig. 1 is a schematic flow chart of an OFD plate drift automatic correction method based on multi-flexible interpolation description according to an embodiment of the present application.
As shown in fig. 1, the main flow of the method is described as follows (steps S101 to S108):
step S101, a target OFD template and target OFD document data are acquired.
In this embodiment, the target OFD template is a template for drift correction at this time, for example, an invoice template of a company, and is composed of two parts: static contents such as fixed forms and heads, variable amounts, dynamic memory such as customer names, and the like. The target OFD board-like document is service data, for example, a field name is UserName in the template, and a value of the corresponding UserName in the board-like document is Zhang Lei, wherein Zhang Lei is service data, that is, data to be filled in or replaced in the target OFD template.
And step S102, extracting a text object, text object coordinates, a path object and path object coordinates of the target OFD template.
Aiming at step S102, analyzing a page object layer of a target OFD template, and determining a text object and a path object of the target OFD template; acquiring a coordinate origin of a target OFD template; text object coordinates and path object coordinates are determined based on the origin of coordinates.
In this embodiment, the Page object layer of the target OFD template is a < Page > </Page > element, and similarly, the Page object includes a text object and a path object, and the element attributes of the text object and the path formation have corresponding coordinates. In the process of extracting, firstly, text objects and path objects are extracted, wherein the text objects are text contents such as 'Zhang San, certain company in A city, ten thousand yuan' and the like, each individual text object corresponds to one coordinate (x, y), namely, each text object corresponds to one text object coordinate, each path object corresponds to a line in a target OFD template, likewise, each path object corresponds to one path object coordinate, in the process of determining the coordinates, drawing and extraction are required to be performed according to constraint information such as a font, a word size, a word spacing, a line spacing, a frame position and the like based on a zero point coordinate origin, the coordinate origin is selected as a display area of a drawing board to be drawn, generally, the upper left corner of a visible area printed on paper is generally understood as a bleeding area (the area with a large cutting error is prevented) is required to be removed if the bleeding area is customized, and the upper left corner after the removal is set as the coordinate origin.
Step S103, extracting text data in the target OFD document data.
In this embodiment, data extraction is performed on target OFD document data, text data to be used is extracted, and useless descriptive text may exist in the target OFD document data, so that in order to make subsequent binding faster, useful document data needs to be extracted in advance.
Step S104, binding the text data with the text object based on the text object coordinates, generating text coordinates, and connecting the text coordinates in series to form a text coordinate sequence.
In this embodiment, the text data and the text object coordinates are bound to generate text coordinates. Sequentially filling text data to corresponding positions according to the sequence, updating text contents corresponding to text object coordinates of the current position into contents corresponding to the text data, for example, the text object coordinates are (2, 3) and (3, 3), the text data is Zhang Lei, filling a page into a gap of (2, 3) when filling, filling an epitaxy into a gap of (3, 3), namely, supplementing effective contents into a target OFD template, so that the text objects in the finally generated OFD template are effective text objects, and connecting the effective text object coordinates in series into a text coordinate sequence, namely, the OFD document which can be actually used.
Step S105, the coordinates of the route object are connected in series to generate a route coordinate sequence.
In this embodiment, after binding the path object and the path object coordinates in the same manner as the text data, a path coordinate sequence is generated.
Step S106, generating a coordinate sequence to be used based on the text coordinate sequence and the path coordinate sequence.
Aiming at step S106, acquiring an X coordinate value of a text coordinate; arranging the text coordinates in ascending order according to X coordinate values to generate a text coordinate sequence to be used; acquiring an X coordinate value of a path coordinate; and arranging the path coordinates in ascending order according to the X coordinate values to generate a path coordinate sequence to be used.
In this embodiment, the text coordinate sequence and the path coordinate sequence are arranged in ascending order according to the X coordinate value of each coordinate, that is, the X value is arranged at the first position and the X value is arranged at the last position, so as to generate a coordinate sequence to be used, that is, the text coordinate sequence to be used and the path coordinate sequence to be used are respectively generated. The text object 1 (200,500), the text object 2 (100,600) and the text object 3 (150,550) are illustrated by a text coordinate sequence, and the text object 2 (100,600), the text object 3 (150,550) and the text object 1 (200,500) are connected in series according to the X value to form the text coordinate sequence to be used, namely [ (100,600), (150,550), (200,500) ].
Step S107, generating ideal coordinate values based on a preset multi-flexible interpolation description algorithm and a coordinate sequence to be used.
Aiming at step S107, calculating a coordinate sequence to be used based on a preset multi-flexible interpolation description algorithm to generate an objective function; determining a target adjustment value based on the objective function; an ideal coordinate value is determined based on the target adjustment value.
In the embodiment, for the obtained coordinate sequence, a preset multi-flexible interpolation description algorithm is applied to perform data fitting on the coordinate sequence to obtain an interpolation description function y=f (x) reflecting the overall distribution rule of the text object, wherein the core formula of the MLID algorithm is that y=f (x) =sum (ai x≡) (i=0, the term, n); wherein n is the interpolation bar number, ai is the interpolation coefficient, bi is the base number. The interpolation value n is automatically set according to the number of path objects in the page, the number of the path objects is different from that of the second text object for conversion, the path objects are the number of lines on the page, the values of the lines are automatically identified when the document is analyzed, and as each path object possibly affects the plate layout, the number directly determines how many terms are needed to construct an accurate interpolation description function.
The method comprises the steps of presetting a multi-flexible interpolation description algorithm, and determining the values of parameters ai and bi in an interpolation description function y=f (x) through least square fitting, so that an objective function Q (a, b) =Σ (yi-f (xi)) -2 reaches the minimum, wherein (xi, yi) is a coordinate point in a coordinate sequence. And then searching the optimal combination of (a, b) in the search space by using a heuristic optimization algorithm, specifically, randomly generating a group of initial (a, b) values as an initial population, and outputting the current optimal solution by iterative optimization until the termination condition is met. Then, defining the obtained interpolation description function y=f (X) as an objective function, and solving an ideal Y coordinate value ŷ i, ŷ i of each text object by an optimization algorithm with the objective of minimizing the total deviation distance between the text coordinates and the objective function, wherein the calculation formula of the ideal Y coordinate value ŷ i, 3562 i is ŷ i=f (xi) (i=1,..m), m is the number of text objects, and xi is the X coordinate value of the ith text object. Finally, solving by adopting a common unconstrained optimization algorithm such as gradient descent and coordinate descent. Taking gradient descent as an example, the iterative formula is ŷ i (t+1) = ŷ i (t) -eta ∂ J/∂ ŷ i, wherein eta is the learning rate, J is the objective function, and the calculation formula of J is J=Σ (yi- ŷ i)/(2).
Specifically, the interpolation coefficient ai and the base bi are calculated by minimizing the objective function Q (a, b), which involves estimating the parameters of the function y=f (x) using the least squares method so that the sum of squares of the differences between the actual coordinate points (xi, yi) and the coordinate points predicted by the interpolation description function is as small as possible. At the code implementation level, a heuristic optimization technology is adopted to find an optimal solution in a possible value space of parameters, namely, a set of initial parameter values are generated through path object coordinates, and then an algorithm gradually adjusts the parameters in an iterative process until an optimal combination is found, so that an objective function reaches a minimum value, and the distribution rule of text objects on an OFD page is reflected most accurately. The whole calculation process is automatically executed by a computer, so that the interpolation function can adapt to complex page layout, and meanwhile, the structural accuracy of the document is reserved. a and b are clusters of values of ai and bi, which are parameters used to construct an interpolation description function y=f (x) in a preset multi-flexible interpolation description algorithm, and in the process of minimizing Q, a set of values of ai and bi is found, which can minimize the sum of squares of the differences between all observation points (xi, yi) and the model predicted f (xi). It should be noted that, each template page corresponds to an objective function, the objective function is set between 0.01 and 0.1, the lower the value of the objective function is, the better the value is, the lower the value is, the more the convergence rate is affected, if the value is a server, 0.01 can be directly specified, and if the value is a terminal used by a person, the setting is required according to the actual performance of the terminal.
And S108, carrying out drift correction on the target OFD template according to the ideal coordinate values to generate a correction document.
In this embodiment, the obtained ideal coordinate values ŷ i of each text object correspondingly adjust the coordinates of the text object in the target OFD template, and then reorganize the page object layer according to the OFD standard, and output the OFD document file after drift correction, that is, generate the final correction document.
The following is illustrated by specific examples:
Assume that the text coordinates of the following three text objects are extracted, and two lines are taken as path objects, so n=2 (two clauses, representing two lines):
The x-coordinate and y-coordinate of the text object are respectively as follows:
text object 1 (1.0, 1.5);
text object 2 (2.0,3.5);
text object 3 (3.0,6.5);
fitting a polynomial interpolation description function using a preset multi-flexible interpolation description algorithm, in this example selecting a quadratic function as the interpolation description function:
y=f(x)=a0+a1*x+a2*x^2；
The optimal values of a0, a1, and a2 need to be found to minimize the objective function Q (a, b), the following parameter values are obtained by the optimization process:
a0 (constant term of quadratic function) =0.1;
a1 (first order coefficient) =0.5;
a2 (quadratic coefficient) =0.2;
thus, the interpolation description function will be y=0.1+0.5xx+0.2xxx2.
Assuming that the x-coordinate is 1.0, the calculation formula for optimizing the Y-coordinate of the text object 1 is:
ŷ=f(1.0)=0.1+0.5*1.0+0.2*1.0^2=0.8；
The calculated ŷ value is the ideal Y coordinate of the text object 1 after the interpolation description function is calculated. And then, calculating all ideal values according to the calculation steps, adjusting the position of each text object according to the calculated ideal Y coordinates, and outputting the corrected OFD document.
In this embodiment, the distribution characteristics of the target OFD template are acquired; dividing a target OFD template into a plurality of document modules based on the distribution characteristics, and determining the number of the document modules; document modules with the same distribution characteristics are taken as a drift correction group.
In order to improve the convenience of operation and the overall drift correction efficiency, the whole target OFD template is divided into a plurality of document modules, the document modules with the same distribution characteristics are used as a drift subgroup, the document modules in each subgroup are ordered according to the number of the document modules, the more the number is, the higher the frequency of use is, accurate correction data are required to be stored after drift correction processing is completed, so that drift correction is performed by using the same scheme when the same situation occurs, and the convenience of selection in subsequent use is improved.
In this embodiment, drift correction data and a result score of a drift correction group are acquired; judging whether drift correction of the correction document is accurate or not based on the result score; if the drift correction of the correction document is accurate, storing drift correction data; if the drift correction of the correction document is inaccurate, the drift correction is performed based on the drift correction result.
And storing the drift correction data with accurate drift correction, and directly adopting the successful drift correction data for correction processing when documents with the same distribution characteristics appear later, thereby reducing the processing pressure of a computer and improving the overall correction efficiency. If the drift correction of the correction document is inaccurate, the correction processing is carried out again by adopting the drift correction mode until the actual requirement is met.
In the embodiment, the correction document is monitored to judge whether the newly added drift content appears; if the newly added drifting content appears, acquiring the position distribution characteristics of the position where the newly added drifting content is located; judging whether the position distribution characteristics are existing distribution characteristics or not; if the distribution characteristics are the existing distribution characteristics, drift correction is carried out on the newly added drift content based on the drift correction data; if the distribution characteristics are not the existing distribution characteristics, drift correction is performed based on the newly added drift content.
In order to improve the efficiency of drift correction, when the correction document with newly added drift content is subjected to drift correction, only the newly added part is required to be subjected to correction processing, the position distribution characteristics of the newly added drift inner barrel are judged, whether the position distribution characteristics are the same as the existing distribution characteristics or not is checked, if the position distribution characteristics are the same as the existing distribution characteristics, the drift correction data corresponding to the existing distribution characteristics are directly adopted for correction, if the position distribution characteristics are different from the existing distribution characteristics, the drift correction data corresponding to the newly added drift content are adopted for drift correction in the drift correction mode, and a specific drift correction method is not repeated here.
It should be noted that, the fitting interpolation describing function algorithm used in the present application may be replaced by using the Loess or IBK algorithm according to actual needs, if the Loess algorithm is adopted, more complex local weighted regression calculation needs to be performed on the text object coordinates, instead of simply applying the global function, and accordingly if a completely different regression method is adopted, new steps may need to be introduced, such as adjusting weights, selecting the neighborhood size, and the like, which will depend on the specifically selected non-parametric regression algorithm. The replacement algorithm and the modification made according to the algorithm herein need to be increased and adjusted as needed according to the actual requirements, and are not particularly limited herein.
