Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
Example one
Fig. 1 shows a flowchart of a loading method of a CAD drawing according to a first embodiment of the present invention, and as shown in fig. 1, the method includes steps S1 to S4, where:
and step S1, when the software loads the CAD drawing, determining the font file used in the CAD drawing.
The execution subject of the invention can be software for loading the CAD drawing, and the software can be an application program. The font file is used for supporting the characters to be displayed in a corresponding font style, for example, when the characters are displayed in a "regular script" style, the "regular script" style needs to be supported by the "regular script file".
In the process of importing software into a CAD drawing, the software first detects a font file used by the CAD drawing, specifically, as shown in fig. 2, elements of a font file required to be used in one CAD drawing include: when the software loads the CAD drawing, the software detects all font styles in the CAD drawing to detect font files used by the font styles, wherein the possible file types of the font files comprise a TTF font file, a TTC font file and a single-line font file, the single-line font file is divided into a large font file and a small font file, and further, a font file list is returned after the detection is completed, and the list comprises the names of all the font files used by the CAD drawing.
And step S2, identifying a first font file which is not loadable by the software from the font files of the CAD drawing.
The software corresponds to a font library of the software, font files in the font library can be loaded by the software, and in order to ensure that the font libraries of the software used by different users have consistency and usability, the font libraries can be automatically distributed to the software through the cloud.
In this embodiment, the returned font file list may be compared with a font library, and if the font library does not include a font file corresponding to a certain font file name in the list, the font file is a first font file that cannot be loaded by software. And sequentially executing the comparison operation until all the font file names in the list are compared, and counting all the first font files which cannot be loaded by the software.
Step S3, determining a second font file for replacing the first font file from the font files loadable by the software according to a preset font matching model.
In order to solve the technical problems that in the prior art, the replacement efficiency and the replacement accuracy rate of the font file for manually replacing the CAD drawing are low, in the embodiment, after the first font file which cannot be loaded is detected, the second font file for replacing the first font file is automatically screened out through the font matching model, and then the CAD drawing is displayed by using the second font file to replace the first font file. Specifically, the font file that can be loaded by the software is a part or all of the font files in the font library.
Optionally, considering that the model is required to perform a calculation operation every time the same CAD drawing is loaded, system resources are wasted; and after the user is unsatisfied with the replacement scheme calculated by the model and manually changes the replacement scheme, the software still uses the model to calculate the replacement file again when opening the CAD drawing next time, at the moment, the user can only manually change the replacement scheme again, and the user experience degree is poor. Based on the above problem, the present embodiment further provides a memory function, and for the replacement scheme accepted by the user, the association relationship between the font files replaced with each other is set, so that when executing the replacement scheme, whether the replacement scheme accepted by the user exists is considered preferentially, if so, the replacement is performed according to the existing replacement scheme, and if not, the replacement scheme is determined by using the model. Specifically, determining a second font file for replacing the first font file from the font files loadable by the software according to a preset font matching model includes:
acquiring a first identifier of the first font file;
detecting whether a second identifier having an association relation with the first identifier is stored in the software;
if the second identifier is stored, directly determining a font file having an association relation with the second identifier from the font files which can be loaded by the software, and using the font file as the second font file;
and if the second identifier is not stored, determining a second font file for replacing the first font file from the font files which can be loaded by the software according to a preset font matching model.
Optionally, after determining, according to a preset font matching model, a second font file for replacing the first font file from the font files loadable by the software if the second identifier is not stored, the method further includes:
acquiring a second identifier of the second font file;
and setting and storing the incidence relation between the first identifier and the acquired second identifier.
In this embodiment, the font matching model may be obtained through neural network learning to improve the accuracy of the font file matching result, specifically, the neural network may be trained through the training set, and the trained model may be tested by using the testing set, and when the accuracy of the model trained by the test result representation satisfies the threshold, the trained model may be used as the font matching model. The training set and the test set respectively comprise a plurality of sample data, the sample data comprises characteristic words of a first font file sample and characteristic words of a second font file sample, and the second font file sample is used for replacing the first font file sample.
The font matching model obtained by training comprises a word embedding layer, a vector conversion layer, a full connection layer and an output layer, wherein the word embedding layer is used for converting feature words into feature vectors, the vector conversion layer is used for calculating a file vector according to all the feature vectors, the full connection layer is used for calculating the matching degree of a first font file and each font file in a font library, and the output layer is used for outputting a second font file with the highest matching degree.
Specifically, determining a second font file for replacing the first font file from the font files loadable by the software according to a preset font matching model includes:
extracting characteristic words of the first font file;
converting the feature words into feature vectors through a word embedding layer of the font matching model;
calculating a file vector of the first font file according to the characteristic vector through a vector conversion layer of the font matching model;
and determining a font file which is matched with the first font file to the highest extent from an output layer of the font matching model according to the file vector of the first font file to serve as the second font file, wherein the output layer comprises a plurality of font files which can be loaded by the software.
Determining a font file with the highest matching degree with the first font file from an output layer of the font matching model according to the file vector of the first font file, wherein the determining of the font file with the highest matching degree with the first font file as the second font file comprises:
acquiring fully connected layers in the font matching model, wherein each fully connected layer has an incidence relation with one font file in the output layer, and each fully connected layer is used for representing a file vector of a corresponding font file;
calculating the product of the file vector represented by the full connection layer and the file vector of the first font file to obtain a vector for representing the matching degree;
converting the vector for representing the matching degree into a numerical value through a softmax function to obtain a matching value for representing the matching degree;
and determining a full connection layer corresponding to the maximum matching value, and determining a font file having an association relation with the full connection layer from the output layer of the font matching model to be used as the second font file.
In this embodiment, a word segmentation technique may be used to segment the first font file, and then the feature words of the first font file are obtained by cleaning and filtering the useless word segmentation, where the feature words include the font file name. It should be noted that before the final participle is used, the common font file names (such as "yjkeng.shx", "yjkchn.shx" and "hztxt.shx") need to be entered into the participle library in advance to ensure that the common font file names are still a complete word in the participle result, so as to optimize the participle effect.
For a computer, text words cannot be directly recognized, so that the text words need to be converted into a language which can be recognized by a machine, that is, feature words are input into a word embedding layer of a font matching model, so that a feature vector of each feature word is obtained, and the feature vector can be directly recognized by the machine. Specifically, each feature word is converted into a feature word vector by using a trained word vector model (e.g. word2vec), for example, "1010011 …" represents a feature vector with dimension 1 × V by using Wi if each feature word is mapped to a feature vector with length V, where i represents the number of extracted feature words in the first font file.
The feature vectors output by the word embedding layer are received through a vector conversion layer of the font matching model, then the file vectors are calculated according to the received feature vectors, for example, the weighting summation is carried out on all the feature vectors, and then the summation result is normalized to obtain the file vector of the first font file.
The number of the full connection layers is the same as that of the font files contained in the output layer, each full connection layer represents a file vector of only one font file in the output layer, each full connection layer receives the file vector of the first font file, then the full connection layer performs product calculation on the file vector and the file vector represented by the full connection layer to obtain a vector for representing the matching degree of the first font file and the font file corresponding to the full connection layer, and then the vector calculated by each full connection layer is converted into a numerical value through a softmax function to obtain a matching value for representing the matching degree of the first font file and the font file corresponding to the full connection layer.
And finally, determining a full connection layer with the maximum matching value, screening font files having an association relation with the full connection layer from the font files contained in the output layer, and outputting the font files from the output layer as second font files.
As an optional embodiment, the replacing operation of the font file may also be executed outside the software, and the software is only responsible for loading the CAD drawing that is successfully replaced, so this embodiment may also provide a method for replacing the font file of the CAD drawing, where an execution subject of the method may be a different application program located in the same device as the software, or may be another device different from the device where the software is located, and specifically, the method includes:
determining a first font file which cannot be loaded in a current CAD drawing;
extracting characteristic words of the first font file;
converting the characteristic words into characteristic vectors through a word embedding layer of a preset font matching model;
calculating a file vector of the first font file according to the characteristic vector through a vector conversion layer of the font matching model;
determining a font file with the highest matching degree with the first font file from an output layer of the font matching model according to the file vector of the first font file to serve as a second font file, wherein the output layer comprises a plurality of font files which can be loaded by software;
and replacing the first font file of the CAD drawing with the second font file.
And step S4, loading the CAD drawing in the software according to the second font file.
In this embodiment, step S2 further determines a font file that can be loaded by software from the font files of the CAD drawing, and finally, the CAD drawing can be displayed in the software using the font file and the second font file.
Optionally, the existing two-dimensional and three-dimensional design software is used for once-only opening and importing the CAD drawings, and when a user is not satisfied with the replacement result, the existing technology cannot realize secondary replacement of the font file. In order to solve this problem, the software of this embodiment also supports a function of replacing the font file again after the CAD drawing is imported. Specifically, after the CAD drawing is loaded in the software according to the second font file, the method further includes:
determining a file type of the first font file;
screening font files belonging to the file type from the font files which can be loaded by the software;
receiving a font file replacing instruction, and determining a font file pointed by the font file replacing instruction from the screened font files as a third font file;
reloading the CAD drawing in the software according to the third font file;
acquiring a third identifier of the third font file;
setting and storing the incidence relation between the first identifier and the third identifier; and
and releasing the association relationship between the first identifier and the second identifier.
After the user replaces the second time, the software stores the replacement result of this time, namely, the association relationship between the first identifier and the third identifier is set and stored, and meanwhile, the memory of the previous replacement is cleared, namely, the association relationship between the first identifier and the second identifier is released.
The following is a detailed description of the complete implementation of the present invention with reference to fig. 3 as an embodiment. Fig. 3 is a schematic diagram illustrating a loading scheme of a CAD drawing according to an embodiment of the present invention, and as shown in fig. 3, in a process of importing a software into a CAD drawing (also referred to as a CAD file), first all font files used in the CAD drawing are determined, then which font files cannot be loaded by the software are determined from the font files of the CAD drawing and are marked as first font files, a second font file is further screened from the font files that can be loaded by the software according to a font matching model and/or a last matching result, and the CAD drawing is displayed by replacing the first font file with the second font file. Further, after the CAD drawing is successfully loaded by the software according to the second font file, the user can perform secondary replacement according to the requirement, namely manually selecting a third font file with the same file type as the first font file, and then reloading the CAD drawing according to the third font file.
The invention aims to solve the problems of font shortage and font replacement in the process of transferring CAD drawings in the field of engineering construction, and automatically matches the existing font files in software based on the font files used in the CAD drawings which are detected to be imported/opened, thereby realizing the automatic replacement and correct display of the font files. By the method, a user does not need to manually replace the font file when importing/opening the CAD drawing, and the missing font file can be updated and replaced for the second time after the CAD drawing is successfully imported.
