The application provides a method for standardizing and processing urban and rural planning drawings, which is mainly used for processing the urban and rural planning drawings in formats of dwg, dxf and the like into urban and rural planning drawings with land use classification standards so as to accord with the urban and rural planning standards and further facilitate the unified warehousing management of the urban and rural planning drawings.

Fig. 1 shows a flowchart of a method for standardizing urban and rural planning drawings according to an embodiment of the present application.

The method comprises the following steps:

step S110, acquiring an urban and rural planning drawing to be subjected to standardization processing, and extracting text elements and surface elements contained in the urban and rural planning drawing;

step S120, fuzzy matching is carried out on the drawing attribute information of the surface element and standard drawing attribute information which is specified by the urban and rural planning standard and used for distinguishing land types, so as to obtain standard drawing attribute information of the surface element and accords with the urban and rural planning standard;

s130, classifying the land of the surface element based on urban and rural planning standards and standard drawing attribute information of the surface element, and determining the land type of the surface element;

step S140, correcting the land type of the surface element based on the text element to obtain the corrected land type of the surface element;

and S150, processing the urban and rural planning drawing into the urban and rural planning drawing with the land classification standard according to the corrected land type of the surface element.

In the embodiment of the application, the obtained urban and rural planning drawing to be subjected to standardization processing is generally a drawing in dwg and dxf format, and in this case, an fme (feature manual engine) spatial data conversion processing system may be adopted to process the urban and rural planning drawing, so as to extract text elements and face elements contained in the urban and rural planning drawing.

The text elements contained in the urban and rural planning drawing are mainly text fields added by a drafter during drawing, and are used for carrying out marked text description on the elements contained in the urban and rural planning drawing. The surface elements contained in the urban and rural planning drawing are mainly land used for each land displayed in the urban and rural planning drawing, and each land is a surface element.

After the surface elements contained in the urban and rural planning drawing are extracted, fuzzy matching is carried out on the drawing attribute information of the surface elements and standard drawing attribute information specified by the urban and rural planning standard, standardization processing of the drawing attribute information of the surface elements is achieved, and the standard drawing attribute information of the surface elements is obtained. The drawing attribute information mainly comprises layer names of layers made by the surface elements and colors filled by the surface elements.

And processing the standard drawing attribute information of the surface elements based on land classification rules specified by urban and rural planning standards, determining land types of the surface elements and realizing land classification of the surface elements. The land type of the surface element is corrected based on the text element to obtain a corrected land type of the surface element.

And then processing the urban and rural planning drawing into the urban and rural planning drawing with the land classification standard according to the corrected land type of the surface element, thereby realizing the land classification standardization processing of the urban and rural planning drawing. The urban and rural planning drawing of the land classification standard mainly means that the division of the land category meets the urban and rural planning standard, the naming of the land category (such as the name of the land category, the code of the land category and the like) meets the urban and rural planning standard, and the visualization of the land category (such as the filling color of ground elements) shows that the land category meets the urban and rural planning standard.

Therefore, in the embodiment of the application, the drawing attribute information of the surface element contained in the urban and rural planning drawing is subjected to fuzzy matching with the standard drawing attribute information specified by the urban and rural planning standard, so that the standardized processing of the drawing attribute information of the surface element is realized. And then the land used for the surface element is classified on the basis of the obtained standard drawing attribute information of the surface element, so that the urban and rural planning standard is met, and the land used classification standardization processing of the urban and rural planning drawing is preliminarily realized. And then the land type of the surface element which accords with the urban and rural planning standard is corrected through the text element, so that the accuracy of the corrected land type of the obtained surface element is further ensured. Therefore, the land use classification standardization processing of the urban and rural planning drawing is automatically and accurately realized on the basis of the corrected land use classification of the surface element.

In one embodiment, the standard land names of the surface elements are obtained by fuzzy matching of the layer names and the standard land names.

In this embodiment, the drawing attribute information of the surface element includes a layer name of a layer where the surface element is located, the standard drawing attribute information for distinguishing land types specified by the urban and rural planning standard includes a standard land name specified by the urban and rural planning standard, and the standard land name of the surface element that meets the urban and rural planning standard is obtained by performing fuzzy matching between the layer name and the standard land name specified by the urban and rural planning standard.

Specifically, when drawing, a drafter usually names the layer name of the layer where the surface element is located as the land name of the surface element. Considering that some cartographers may have irregular behaviors when naming the layer names (i.e., the land names of the surface elements), the named layer names may not conform to the standard land names specified by the urban and rural planning standards. Therefore, by fuzzy matching the layer name and the standard land name, the layer name with consistent real semantics can be converted into the corresponding standard land name, so as to obtain the standard land name of the surface element. Furthermore, the land types of the surface elements can be obtained by classifying the standard land names of the surface elements based on land division rules specified by urban and rural planning standards.

The method can adopt a natural language processing method to respectively process keywords contained in the image layer name and standard land names specified by the urban and rural planning standard, and further carry out fuzzy matching on the image layer name and the standard land names according to the semantic similarity between the keywords and the standard land names.

The embodiment has the advantages that fuzzy matching is carried out in a text processing mode, land use classification is carried out, land use types of the surface elements are standardized, and meanwhile information of layer names set by a drawing person in the drawing process is fully utilized.

In an embodiment, the filtering of the layer names is preferentially performed on the surface elements with larger number of the included atomic keywords.

In this embodiment, the layer where the surface element is located is screened according to the sequence of the number of the included atomic keywords from large to small, so as to obtain the layer name of the layer where the surface element is located, and match the layer name with the standard land name specified by the urban and rural planning standard.

Specifically, the atomic key refers to a key for describing a minimum unit of a place name. The land name of a face element may be composed of a plurality of atomic keywords. The larger the number of the atomic keywords contained in the layer name of the layer where the surface element is located is, the higher the priority is to screen the layer name of the surface element.

The embodiment has the advantages that the layer names are screened in the mode, so that omission of the screened layers can be avoided, and the coverage rate of layer screening is ensured.

In one embodiment, the standard land names of the face elements are obtained by fuzzy matching of the fill color and the standard fill color.

In this embodiment, the drawing attribute information of the surface element includes a color filled in the surface element, the standard drawing attribute information for distinguishing land types defined by the urban and rural planning standard includes a standard filling color defined by the urban and rural planning standard, and the color filled in the surface element and the standard filling color are subjected to fuzzy matching to obtain the standard filling color of the surface element, which meets the urban and rural planning standard.

Specifically, when drawing, the drafter needs to fill the colors of the corresponding surface elements according to the land types. Considering that some cartographers have irregular behaviors when filling colors, the colors filled by the surface elements do not conform to standard filling colors specified by urban and rural planning standards. Therefore, by fuzzy matching the color filled in the surface element with the standard filling color, the color filled in the surface element can be converted into the corresponding standard filling color, thereby obtaining the standard filling color of the surface element. Furthermore, the standard filling colors of the surface elements can be classified by land based on land division rules specified by urban and rural planning standards to obtain land categories of the surface elements.

The embodiment has the advantages that the image processing mode is used for fuzzy matching and land use classification, the land use category of the surface element is standardized, and the color information set by a drafter in the drawing process is fully utilized.

In one embodiment, the distance between the RGB value of the color filled in the surface element and the RGB value of each standard fill color is calculated, and the standard fill color with the smallest distance is used as the standard fill color of the surface element.

Specifically, the smaller the distance between the RGB value of the color filled in the surface element and the RGB value of the standard filling color is, the more similar the color filled in the surface element is to the standard filling color. And using the most similar standard filling color as the standard filling color of the surface element to realize fuzzy matching between the filling color of the surface element and the standard filling color.

In an embodiment, in the process of performing fuzzy matching and land use classification according to the layer name, fuzzy matching is performed in parallel according to filling colors and land use classification is performed. And the land types of the surface elements obtained respectively are compared in a cross mode, so that the accuracy and the coverage rate of the land types of the surface elements are improved.

Further, it is considered that the drafter sets the text information to be generally closer to the drafter's real drafting intention in the drafting process than the color information set by the drafter. Therefore, when cross-matching the land types of the surface elements, the user type of the surface element obtained by fuzzy matching according to the layer name is given as the main type, and the user type of the surface element obtained by fuzzy matching according to the fill color is given as the subsidiary type. And when the two types of land use described by the same surface element conflict, the user type of the surface element obtained by fuzzy matching according to the layer name is taken as the standard.

In one embodiment, annotation information associated with the face element in the text element is extracted. The land type of the surface element is corrected based on the land type information included in the label information, and the corrected land type of the surface element is obtained.

Specifically, the label information in the text elements included in the urban and rural planning drawing is generally the information added by the drafter for a specific surface element, and generally describes the land use category information of the specific surface element. Therefore, the annotation information in the text element is extracted, the face element associated with the annotation information is specified, and the land type of the face element is corrected based on the land type information included in the annotation information, thereby obtaining the corrected land type of the face element.

In one embodiment, the face element associated with the annotation information is located by a coordinate distance between the annotation information and the face element.

In the embodiment, a first coordinate of each surface element in the urban and rural planning drawing and a second coordinate of the marking information in the text element in the urban and rural planning drawing are obtained. And calculating the distance between the second coordinate and each first coordinate, and determining the surface element corresponding to the first coordinate with the minimum distance as the surface element associated with the labeling information.

In one embodiment, after extracting the labeling information associated with the face element in the text element, fuzzy matching is performed on the labeling information and a standard field for distinguishing land types specified by the urban and rural planning standard to obtain standardized labeling information, and the land type of the face element is corrected based on the land type information contained in the standardized labeling information.

Specifically, after the annotation information is extracted, the annotation information is normalized before the annotation information is used to correct the land use type of the surface element. The standardization of the marking information is realized by carrying out fuzzy matching on the marking information and standard fields specified by urban and rural planning standards and converting the marking information into corresponding standard fields.

In one embodiment, after acquiring the urban and rural planning drawing to be standardized, the elevation value of the element included in the urban and rural planning drawing is corrected to be 0.

Specifically, in the drawing process, part of drawing personnel can directly capture the attribute information of each element into the urban and rural planning drawing, so that the urban and rural planning drawing is a three-dimensional drawing. The urban and rural planning standard generally requires that the urban and rural planning drawing should be a two-dimensional drawing, so the elevation value of the element is corrected to be 0 so as to meet the urban and rural planning standard.

In an embodiment, after the urban and rural planning drawing to be subjected to standardization processing is obtained, invalid information contained in the urban and rural planning drawing and outside the urban and rural planning standard is removed, effective information contained in the urban and rural planning drawing and inside the urban and rural planning standard is obtained, and text elements and face elements contained in the urban and rural planning drawing are extracted from the effective information.

Fig. 2 is a schematic flowchart illustrating detailed process of standardization of urban and rural planning drawings according to an embodiment of the present application.

In this embodiment, after the urban and rural planning drawing to be standardized is acquired, the standard inspection is performed on the urban and rural planning drawing. If the standard check passes, the invalid information screening is continued, and if the standard check does not pass, the standardization processing is stopped.

The standard inspection mainly includes an OGC (Open Geospatial Consortium) standard inspection, an elevation inspection, and a file format inspection. And if the elevation value is not 0, correcting the elevation value to be 0.

The invalid information screening mainly comprises invalid geometric type screening, invalid layer name screening, invalid labeling information screening and invalid filling color screening. And after the invalid information is screened, distributing the residual valid information into the marking information contained in the surface element and the text element.

The processing of the face elements mainly comprises fuzzy matching of the face elements according to the layer names and fuzzy matching of the face elements according to filling colors. And in the process of carrying out fuzzy matching according to the layer names, carrying out fuzzy matching on the layer names of the layers where the surface elements are located and the standard land names specified by the urban and rural planning standards to obtain the standard land names of the surface elements, and further carrying out three-level classification on the standard land names of the surface elements according to land division rules specified by the urban and rural planning standards to obtain the land categories of the surface elements. And in the process of carrying out fuzzy matching on the standard filling colors according to the filling colors, carrying out fuzzy matching on the filling colors of the surface elements and the standard filling colors specified by the urban and rural planning standards to obtain the standard filling colors of the surface elements, and further carrying out three-level classification on the standard filling colors of the surface elements according to land division rules specified by the urban and rural planning standards to obtain the land types of the surface elements. And then the land types of the surface elements obtained by fuzzy matching according to the layer names and the land types of the surface elements obtained by fuzzy matching according to the filling colors are cross-compared, and the land types of the surface elements are adjusted by integrating the land type division results of the two.

And (3) standardizing the fields contained in the marking information, and correcting the land types of the surface elements according to the standardized marking information to obtain corrected land types of the surface elements.

Further, the normalized information mapping process is performed on the corrected land type of the surface element.
