Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically, to a method, apparatus, storage medium, and electronic device for processing drawing annotations. Background Technology

[0002] Currently, in CAD drawing design, designers frequently refer to other drawings for detailed design or subsequent process design. In related technologies, designers typically use the Object Linking and Embedding (OLE) function built into the CAD software or external recognition tools to insert files in formats such as PDF, JPG, PNG, and BMP into the CAD drawings as design references.

[0003] However, drawings referenced in the above way cannot be edited or adjusted in CAD software. For example, external recognition tools vectorize the content in image-format CAD drawings, that is, they convert the boundaries of the content in image-format CAD drawings into boundaries formed by discrete line segments. In this process, the engineering annotation symbols in image-format CAD drawings are also recognized as discrete line segments. These discrete engineering annotation symbols are not actually converted into internal objects of CAD software. They can only be referenced and cannot be edited or adjusted, thus failing to meet the detailed design needs of designers.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

[0005] This invention provides a method, apparatus, storage medium, and electronic device for processing drawing annotations, to at least solve the technical problem in the prior art that engineering annotation symbols cannot be edited after being vectorized.

[0008] Furthermore, the method for processing drawing annotations also includes: taking a screenshot of the first drawing annotation to generate a first drawing annotation image; comparing the first drawing annotation image with the drawing annotation image to be identified to obtain a second difference degree; and determining whether the first drawing annotation passes the reverse verification based on the second difference degree.

[0009] Furthermore, the method for processing drawing annotations also includes: if the second difference degree is less than or equal to the first threshold, determining that the first drawing annotation passes the reverse verification.

[0010] Furthermore, the method for processing drawing annotations also includes: obtaining a set of drawing annotations, taking a screenshot of each drawing annotation in the set, generating a drawing annotation image corresponding to each drawing annotation, and constructing a target image library based on the drawing annotation images.

[0011] Furthermore, the method for processing drawing annotations also includes: obtaining the character expression corresponding to each drawing annotation; and constructing a mapping table based on each drawing annotation, the image identifier corresponding to the drawing annotation image, and the character expression, wherein the mapping table is used to represent the correspondence between each drawing annotation and the character expression.

[0012] Furthermore, the method for processing drawing annotations also includes: acquiring a target drawing image; taking a screenshot of the area in the target drawing image that contains the drawing annotations to be identified, and obtaining an image of the drawing annotations to be identified.

[0013] According to another aspect of the present invention, a drawing annotation processing apparatus is also provided, comprising: an acquisition module for acquiring a drawing annotation image to be identified; a first determination module for determining a target drawing annotation image from a target image library based on a first difference between the drawing annotation image to be identified and drawing annotation images in a target image library; a second determination module for acquiring an image identifier corresponding to the target drawing annotation image and determining a target character expression corresponding to the drawing annotation to be identified in the drawing annotation image to be identified based on the image identifier; and a processing module for generating a target drawing annotation based on the target character expression, wherein the target drawing annotation is a drawing annotation in an editable format.

[0014] According to another aspect of the present invention, a computer-readable storage medium is also provided, wherein a computer program is stored in the computer program, wherein the computer program is configured to execute the above-described drawing annotation processing method when it is run.

[0015] According to another aspect of the present invention, an electronic device is also provided, the electronic device including one or more processors; a memory for storing one or more programs, wherein when the one or more programs are executed by the one or more processors, the one or more processors are configured to run the programs, wherein the programs are configured to execute the above-described drawing annotation processing method during runtime.

[0016] According to another aspect of the present invention, a computer program product is also provided, including a computer program / instruction, which, when executed by a processor, implements the above-described drawing annotation processing method.

[0017] In this embodiment of the invention, a method is adopted to convert image-format drawing annotations into editable format drawing annotations by using target character expressions.

Thus, the target character expression can be determined based on the image identifier corresponding to the target drawing annotation image. Then, the target drawing annotation is generated based on the target character expression, realizing the conversion of image-format drawing annotations into editable format drawing annotations. This greatly facilitates designers in further refining the drawing design, saves time and manpower costs, and improves the work efficiency of designers.

[0028] Example 1

[0029] According to an embodiment of the present invention, a method embodiment for processing drawing annotations is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0030] Figure 1 This is a flowchart of an optional drawing annotation processing method according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0031] Step S101: Obtain the drawing annotation image to be identified.

[0032] In the above steps, the image of the drawing annotation to be identified can be acquired through devices such as application systems, processors, and electronic devices. Optionally, the image of the drawing annotation to be identified can be a file image in formats such as PDF, JPG, PNG, and BMP, containing the drawing annotation to be identified. Optionally, the drawing can be a CAD drawing such as a mechanical part drawing, an architectural wall drawing, or a structural foundation drawing. Optionally, taking a mechanical part drawing as an example, the drawing annotation can be engineering annotation symbols such as straightness, flatness, and cylindricity.

[0033] Step S102: Determine the target drawing annotation image from the target image library based on the first difference between the drawing annotation image to be identified and the drawing annotation images in the target image library.

[0034] In the above steps, the target library can be a pre-built standard graphic library of engineering annotation symbols. The target library contains multiple drawing annotation images, and each drawing annotation image contains one type of drawing annotation, namely an engineering annotation symbol. The target drawing annotation image can be the same as the drawing annotation image to be identified.

[0035] Optionally, the target drawing annotation image can be determined by comparing the pixel values ​​of two images, comparing the image to be identified with multiple drawing annotation images in the target image library. Specifically, the target drawing annotation image is determined from the target image library based on the first degree of difference between the image to be identified and the drawing annotation images in the target image library. Optionally, the target threshold can be set by the designer according to the accuracy requirements. For example, a target threshold of 5 means that if the number of different pixels between two images is less than or equal to 5, the two images are considered identical.

[0036] Optionally, if the first difference is less than or equal to the target threshold, the target drawing annotation image is determined to be the drawing annotation image to be identified. For example, if the difference between the drawing annotation image to be identified and drawing annotation image A in the target library is 4 (i.e., the first difference), meaning there are 4 different pixels between the two images; and the difference between the drawing annotation image to be identified and drawing annotation image B in the target library is 6 (i.e., there are 6 different pixels between the two images), and the target threshold is set to 5, the difference between the drawing annotation image to be identified and drawing annotation image A in the target library is 4 (i.e., the first difference) is less than the target threshold of 5. In this case, the drawing annotation image to be identified and drawing annotation image A in the target library are considered to be the same image.

[0037] Step S103: Obtain the image identifier corresponding to the target drawing annotation image, and determine the target character expression corresponding to the drawing annotation to be recognized in the drawing annotation image based on the image identifier.

[0038] In the above steps, the image identifier can be the name of the image labeled on the target drawing. For example, if the image format is JPG, the image name can be 1.jpg.

[0039] Optionally, the target character expression corresponding to the drawing annotation in the image to be identified can be determined from a pre-built mapping table. For example, the mapping table stores multiple image identifiers (image names) and multiple character expressions. By inputting the image identifier corresponding to the target drawing annotation image, the corresponding character expression (target character expression) can be obtained. For example, if the mapping table stores the image name: 1.jpg and the character expression: \#\0^, and the image identifier (image name) corresponding to the target drawing annotation image is 1.jpg, inputting 1.jpg into the mapping table will yield the target character expression \#\0^, meaning the target character expression corresponding to the drawing annotation in the image to be identified is \#\0^.

[0040] Step S104: Generate target drawing annotations based on the target character expression, wherein the target drawing annotations are drawing annotations in an editable format.

[0041] Optionally, by using target character expressions in CAD software, the drawing annotations to be recognized in the drawing annotation image can be converted into drawing annotations that can be edited in the CAD software, i.e., target drawing annotations.

[0042] Based on the scheme defined in steps S101 to S104 above, it can be understood that in this embodiment of the invention, the method of converting image-format drawing annotations into editable format drawing annotations by using target character expressions is adopted. First, the drawing annotation image to be identified is obtained. Then, based on the first difference between the drawing annotation image to be identified and the drawing annotation images in the target image library, the target drawing annotation image is determined from the target image library. Then, the image identifier corresponding to the target drawing annotation image is obtained. Based on the image identifier, the target character expression corresponding to the drawing annotation to be identified in the drawing annotation image to be identified is determined. Then, the target drawing annotation is generated based on the target character expression, wherein the target drawing annotation is an editable format drawing annotation.

[0043] It is noteworthy that, in the above process, acquiring the image of the drawing annotation to be identified provides a data foundation for subsequently determining the target drawing annotation image from the target library. Based on the first degree of difference between the image of the drawing annotation to be identified and the drawing annotation images in the target library, the target drawing annotation image can be determined from the target library. Thus, based on the image identifier corresponding to the target drawing annotation image, the target character expression can be determined, and then the target drawing annotation can be generated based on the target character expression. This realizes the conversion of image-format drawing annotations into editable format drawing annotations, which greatly facilitates designers in further refining the drawing design, saves time and manpower costs, and improves the work efficiency of designers.

[0044] Therefore, the technical solution of this invention achieves the goal of converting image-format drawing annotations into editable format drawing annotations, thereby improving the efficiency of designers' drawing detailing work and solving the technical problem in the prior art that engineering annotation symbols cannot be edited after vectorization.

[0045] In one optional embodiment, during the process of generating target drawing annotations based on target character expressions, first drawing annotations are generated based on target character expressions, then reverse verification is performed on the first drawing annotations, and if the first drawing annotations pass the reverse verification, the first drawing annotations are determined to be target drawing annotations.

[0046] Specifically, after generating the first drawing annotation based on the target character expression, it is necessary to verify whether the generated first drawing annotation is correct. For example, by inputting the target character expression \#\0^ into the CAD software, the generated first drawing annotation is straightness, and it is necessary to verify whether the straightness is the drawing annotation to be recognized.

[0047] In one optional embodiment, during the reverse verification process of the first drawing annotation, the first drawing annotation is first captured to generate a first drawing annotation image. Then, the first drawing annotation image is compared with the drawing annotation image to be identified to obtain a second difference degree. Finally, the first drawing annotation is determined to pass the reverse verification based on the second difference degree.

[0048] Optionally, after generating engineering annotation symbols (i.e., the first drawing annotations) in the CAD software using character expressions, the newly generated engineering annotation symbols are extracted to generate an image file, i.e., the first drawing annotation image. Further, this image is compared with the drawing annotation image to be identified to obtain a second difference score. Further, based on the second difference score, it is determined whether the first drawing annotation passes the reverse verification.

[0049] In one optional embodiment, during the process of determining whether the first drawing annotation passes the reverse verification based on the second difference degree, if the second difference degree is less than or equal to the first threshold, the first drawing annotation is determined to have passed the reverse verification.

[0050] Optionally, the first threshold can be set by the designer according to the accuracy requirements. For example, the first threshold can be set to 5, meaning that if the number of different pixels between two images is less than or equal to 5, the two images are considered to be the same.

[0051] For example, if the difference between the first drawing annotation image and the drawing annotation image to be identified, i.e. the second difference degree, is 4, that is, there are 4 different pixels between the two images, and the first threshold is set to 5, the difference degree between the first drawing annotation image and the drawing annotation image to be identified is 4, which is less than the first threshold of 5. At this time, it is considered that the first drawing annotation image and the drawing annotation image to be identified are the same image, that is, the first drawing annotation is determined to pass the reverse verification.

[0052] In one optional embodiment, before obtaining the drawing annotation image to be identified, a set of drawing annotations is obtained, each drawing annotation in the set is screenshotted to generate a drawing annotation image corresponding to each drawing annotation, and then a target image library is constructed based on the drawing annotation images.

[0053] Optionally, the drawing annotation set can be a collection obtained by exhaustively listing all possible drawing annotations, i.e., engineering annotation symbols, generated in CAD software. Alternatively, a screenshot tool widely used in this field can be used to process each drawing annotation in the drawing annotation set into a screenshot, generating a corresponding drawing annotation image for each annotation.

[0054] Furthermore, based on the annotated images on the drawings, a target image library is constructed, namely the pre-built standard graphic library of engineering annotation symbols mentioned above. Optionally, the target image library can be stored in a folder under the root directory of the CAD software, or it can be stored on a cloud server; this invention does not limit this.

[0055] In one optional embodiment, after constructing the target image library based on the drawing annotation images, the character expression corresponding to each drawing annotation is obtained. Then, based on each drawing annotation, the image identifier corresponding to the drawing annotation image, and the character expression, a mapping relationship table is constructed. The mapping relationship table is used to represent the correspondence between each drawing annotation and the character expression.

[0056] Optionally, each drawing annotation has a corresponding character expression. For example, the character expression for straightness is \#\0^, the character expression for flatness is \#\1^, the character expression for roundness is \#\2^, the character expression for profile is \#\3^, and the character expression for roughness is \R\0^, etc.

[0057] Optionally, the mapping table, which is the pre-constructed mapping table mentioned above, contains at least each drawing annotation, the image identifier corresponding to the drawing annotation image, and a character expression. For example, the first row of the mapping table contains the serial number, drawing annotation, image identifier, and character expression, while the second row contains the serial number 1, straightness, 1.jpg, and 0^.

[0058] In one optional embodiment, during the process of obtaining the drawing annotation image to be identified, the target drawing image is first obtained, and then the area containing the drawing annotation to be identified in the target drawing image is captured to obtain the drawing annotation image to be identified.

[0059] Optionally, the target drawing image can be a drawing that includes the entire engineering design, such as a mechanical part drawing, which includes both the part and the engineering annotation symbols.

[0060] Optional, Figure 2 This is a flowchart of an optional drawing annotation processing system according to an embodiment of the present invention, such as... Figure 2 As shown, the first step is to extract the engineering annotation symbols to be recognized and generate an image file, thus obtaining the drawing annotation image to be recognized. Specifically, through the drawing annotation processing system, the target drawing image (e.g., a JPG format drawing image) is inserted into the CAD software. Then, the area containing the drawing annotation to be recognized in the target drawing image is cropped to obtain the drawing annotation image to be recognized. At least one drawing annotation image must be obtained.

[0061] Furthermore, the captured image is standardized. Specifically, the graphic file is transformed according to the length and width ratio of graphics in a standard image library to obtain a standardized image of the engineering annotation symbol. The ratio transformation method used adopts a widely used method in this field and is not limited here.

[0062] Furthermore, the standardized drawing image is compared with the engineering annotation standard symbol graphic library. If the comparison result is within the matching range, the engineering annotation symbol is considered to have been identified, and the process proceeds to the second verification step. Optionally, if the comparison result is not within the matching range, a prompt dialog box can be generated to prompt the designer to perform manual identification.

[0063] Furthermore, the secondary verification step includes: for successfully recognized engineering annotation symbols, extracting the corresponding character expression from the mapping table, and generating the engineering annotation symbol in the CAD software using the character expression. Specifically, inputting the character expression into the CAD software generates the corresponding engineering annotation symbol. Further, capturing the newly generated engineering annotation symbol to create an image file, and comparing this image with the image file from the first step. If the comparison result is within the matching range, recognition is successful; otherwise, manual assistance is required. Before comparing this image with the image file from the first step, the captured image must also undergo standardization processing, using the same method as described above for processing the drawing annotation image to be recognized, which will not be elaborated here.

[0064] Optionally, for engineering annotation symbols that are not in the standard graphic library, such as a few non-standard engineering annotation symbols, prompt dialog boxes can be generated to prompt designers to perform manual identification.

[0065] Optional, Figure 3 This is a flowchart of an optional method for constructing a target image library and a mapping relationship table according to an embodiment of the present invention, such as... Figure 3 As shown, firstly, a standard graphic library of engineering annotation symbols is established. Specifically, in the CAD software, possible engineering annotation symbols are generated exhaustively under the standard settings, such as straightness, flatness, roundness, cylindricity, profile, coaxiality, symmetry, position, radial runout, roughness, reference target code, etc.

[0066] Furthermore, engineering annotation symbols are cropped one by one at a specified resolution and uniform size to obtain image files of engineering annotation symbols, thus constructing a standard graphic library of engineering annotation symbols. The files can be in formats such as BMP, JPG, and PNG. Cropping engineering annotation symbols one by one at a specified resolution and uniform size can be done by cropping 64*64 images at a resolution of 1024*768.

[0067] Furthermore, a mapping table is constructed. Specifically, each engineering annotation symbol is mapped to a character expression in the CAD software. For example, the character expression for straightness is \#\0^, for flatness is \#\1^, for roundness is \#\2^, for profile is \#\3^, and for roughness is \R\0^, etc. The mapping table can be a text file, a table file, a database table file, etc., and this embodiment does not impose any limitations.

[0068] Therefore, the technical solution of this invention achieves the goal of converting image-format drawing annotations into editable format drawing annotations, thereby improving the efficiency of designers' drawing detailing work and solving the technical problem in the prior art that engineering annotation symbols cannot be edited after vectorization.
