Fig. 1 shows a flowchart of an urban and rural planning drawing standardization processing method 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 standardized processing, and extracting text elements and face elements contained in the urban and rural planning drawing;
step S120, fuzzy matching is carried out on the drawing attribute information of the face element and the standard drawing attribute information for distinguishing land types, which is specified by the urban and rural planning standard, so as to obtain the standard drawing attribute information of the face element, which accords with the urban and rural planning standard;
step S130, classifying land based on urban and rural planning standards and standard drawing attribute information of the face elements, and determining land categories of the face elements;
step S140, correcting the land category of the face element based on the text element to obtain the corrected land category of the face element;
and step S150, processing the urban and rural planning drawings into urban and rural planning drawings of land classification standards according to the land categories after the correction of the surface elements.
In this embodiment of the present application, the obtained urban and rural planning drawing to be standardized is usually a drawing in dwg and dxf formats, and in this case, a FME (Feature Manipulate Engine) spatial data conversion processing system may be used to process the urban and rural planning drawing, so as to extract text elements and surface elements included 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 diagrammer during drawing, and are used for carrying out labeled text description on the elements contained in the urban and rural planning drawing. The face elements contained in the urban and rural planning drawings are mainly all the land areas displayed in the urban and rural planning drawings, and each land area is a face element.
After the face elements contained in the urban and rural planning drawing are extracted, fuzzy matching is carried out on the drawing attribute information of the face elements and standard drawing attribute information specified by urban and rural planning standards, standardized processing of the drawing attribute information of the face elements is achieved, and standard drawing attribute information of the face elements is obtained. The drawing attribute information mainly comprises layer names of layers formed by face elements and colors filled by the face elements.
And processing the standard drawing attribute information of the face elements based on land classification rules specified by urban and rural planning standards, determining land classification of the face elements, and realizing land classification of the face elements. Further, the land category of the face element is corrected based on the text element, and the corrected land category of the face element is obtained.
And then processing the urban and rural planning drawings into urban and rural planning drawings of land classification standards according to the corrected land categories of the face elements, thereby realizing land classification standardization processing of the urban and rural planning drawings. The urban and rural planning drawing of the land classification standard mainly refers to that the classification of the land class accords with the urban and rural planning standard, the naming of the land class (such as the name of the land class, the code of the land class and the like) accords with the urban and rural planning standard, and the visualization of the land class (such as the filling color of the land elements) shows that the land class accords with the urban and rural planning standard.
Therefore, in the embodiment of the application, the mapping attribute information of the face element contained in the urban and rural planning drawing is subjected to fuzzy matching with the standard mapping attribute information specified by the urban and rural planning standard, so that the standardized processing of the mapping attribute information of the face element is realized. And the surface elements are classified on the basis of the obtained standard drawing attribute information of the surface elements, so that the surface elements accord with urban and rural planning standards, and land classification standardization processing of urban and rural planning drawings is primarily realized. And the land category of the face element which accords with the urban and rural planning standard is corrected through the text element, so that the accuracy of the corrected land category of the obtained face element is further ensured. Therefore, land classification standardization processing of urban and rural planning drawings is automatically and accurately realized on the basis of land classification after correction of the face elements.
In one embodiment, the standard land name of the face element is obtained by fuzzy matching the layer name with the standard land name.
In this embodiment, the drawing attribute information of the face element includes a layer name of a layer where the face element is located, the standard drawing attribute information for distinguishing the land type specified by the urban and rural planning standard includes a standard land name specified by the urban and rural planning standard, and the layer name is subjected to fuzzy matching with the standard land name specified by the urban and rural planning standard to obtain the standard land name of the face element conforming to the urban and rural planning standard.
Specifically, when drawing, a drawing staff usually names a layer name of a layer where a face element is located as a place name of the face element. Considering that some diagrammers may have an irregular behavior in naming the layer names (i.e., the land names of face elements), the named layer names may not conform to the standard land names specified by the urban and rural planning standards. Therefore, by performing fuzzy matching between the layer names and the standard land names, the layer names with the same real semantics can be converted into the corresponding standard land names, and the standard land names of the face elements can be obtained. Further, the land classification can be performed on the basis of the standard land names of the face elements according to the land classification rule defined by the urban and rural planning standard, and the land classification of the face elements can be obtained.
The method comprises the steps of processing keywords contained in the layer names and standard land names specified by urban and rural planning standards respectively by adopting a natural language processing method, and performing fuzzy matching on the layer names and the standard land names according to semantic similarity between the keywords and the standard land names.
The embodiment has the advantages that fuzzy matching is performed in a text processing mode so as to classify land, and the land category of the surface elements is standardized, and meanwhile, the information of the layer names set in the drawing process by drawing staff is fully utilized.
In one embodiment, the filtering of the layer names is preferentially performed for face elements that contain a greater number of atomic keywords.
In this embodiment, the layer name of the layer where the face element is located is obtained by screening the layers where the face element is located according to the order of the number of the included atomic keywords from large to small, so as to match the layer name with the standard land name specified by the urban and rural planning standard.
Specifically, an atomic keyword refers to a keyword for describing a minimum unit of place name. The place 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 face element is located, the more preferentially the layer name of the face element is screened out.
The method has the advantages that the method can be used for screening the layer names, so that the screened layers cannot be missed, and the coverage rate of layer screening is guaranteed.
In one embodiment, the standard land name of the face element is obtained by fuzzy matching the fill color with the standard fill color.
In this embodiment, the drawing attribute information of the face element includes a face element filled color, the standard drawing attribute information for distinguishing the land type specified by the urban and rural planning standard includes a standard filled color specified by the urban and rural planning standard, and the face element filled color and the standard filled color are subjected to fuzzy matching to obtain a standard filled color of the face element conforming to the urban and rural planning standard.
Specifically, the diagrammer needs to fill the colors of the corresponding face elements according to the land categories during the diagramming. Considering that partial diagrammers can have non-canonical behaviors in filling colors, the face element filling colors do not accord with standard filling colors specified by urban and rural planning standards. Therefore, by performing blur matching of the face element filled color and the standard filled color, the face element filled color can be converted into the corresponding standard filled color, and the standard filled color of the face element can be obtained. Furthermore, the standard filling colors of the face elements can be classified into land based on land classification rules defined by urban and rural planning standards, and land categories of the face elements can be obtained.
The embodiment has the advantages that fuzzy matching is carried out in an image processing mode so as to classify land, and color information set by a diagrammer in the diagramming process is fully utilized while the land type of the surface element is standardized.
In one embodiment, the distance between the RGB values of the color filled by the face element and the RGB values of the respective standard fill colors is calculated, and the standard fill color with the smallest distance is taken as the standard fill color of the face element.
Specifically, the smaller the distance between the RGB values of the face element filled color and the RGB values of the standard filled color, the more similar the face element filled color is to the standard filled color. And using the most similar standard filling color as the standard filling color of the face element, and realizing fuzzy matching between the filling color of the face element and the standard filling color.
In one embodiment, in the process of performing fuzzy matching according to the layer names and performing land classification, fuzzy matching is performed in parallel according to the filling colors and performing land classification. And the land categories of the surface elements obtained respectively are subjected to cross comparison, so that the accuracy and coverage rate of the land categories of the surface elements are improved.
Further, considering that the diagramming staff is in the process of diagramming, the text information of the diagramming staff is generally closer to the real diagramming intention of the diagramming staff than the color information of the diagramming staff. Therefore, when the land type of the face element is cross-compared, the user type of the face element obtained by performing fuzzy matching according to the layer name is mainly used, and the user type of the face element obtained by performing fuzzy matching according to the filling color is mainly used. When the two conflict with each other on the land category described by the same face element, the user category of the face element obtained by fuzzy matching according to the layer name is used as the reference.
In one embodiment, annotation information associated with a face element in a text element is extracted. The land type of the face element is corrected based on the land type information included in the label information, and a corrected land type of the face element is obtained.
Specifically, the labeling information in the text element included in the urban and rural planning drawing is usually information added by the diagrammer for a specific face element, and the land category information of the specific face element is generally described. Therefore, after the labeling information in the text element is extracted, the face element associated with the labeling information is determined, and the land type of the face element is corrected based on the land type information included in the labeling information, so that the corrected land type of the face element is obtained.
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 face element in an urban and rural planning drawing and a second coordinate of labeling information in a text element in the urban and rural planning drawing are obtained. And calculating the distance between the second coordinates and each first coordinate, and determining the surface element corresponding to the first coordinate with the smallest 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, the labeling information is subjected to fuzzy matching with a standard field for distinguishing the land category specified by the urban and rural planning standard, so as to obtain standardized labeling information, and the land category of the face element is corrected based on the land category information contained in the standardized labeling information.
Specifically, after the labeling information is extracted, the labeling information is normalized before being used to correct the land category of the face element. The standardization of the labeling information is realized by carrying out fuzzy matching on the labeling information and standard fields specified by urban and rural planning standards and converting the labeling information into corresponding standard fields.
In one embodiment, after the urban and rural planning drawing to be standardized is acquired, the elevation value of the element included in the urban and rural planning drawing is corrected to 0.
Specifically, in the drawing process, the attribute information of each element is directly captured into the urban and rural planning drawing by considering that part of drawing staff can directly capture the attribute information of each element, 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 that the elevation value of the element is corrected to 0 to meet the urban and rural planning standard.
In an embodiment, after the urban and rural planning drawing to be standardized is acquired, invalid information, which is contained in the urban and rural planning drawing and is outside the urban and rural planning standard, is removed, and valid information, which is contained in the urban and rural planning drawing and is inside the urban and rural planning standard, is obtained, so that text elements and face elements contained in the urban and rural planning drawing are extracted from the valid information.
Fig. 2 shows a detailed flow diagram of an urban and rural planning drawing standardization process according to an embodiment of the present application.
In the embodiment, after the urban and rural planning drawing to be standardized is obtained, standard inspection is performed on the urban and rural planning drawing. If the standard check is passed, the invalid information screening is continued, and if the standard check is not passed, the normalization processing is stopped.
Among them, the standard inspection mainly includes OGC (Open Geospatial Consortium, open geographic space information alliance) standard inspection, elevation value inspection, and file format inspection. If the elevation value is not 0, the elevation value is corrected to 0.
The invalid information filtering mainly comprises an invalid geometric type filtering, an invalid layer name filtering, an invalid labeling information filtering and an invalid filling color filtering. After the invalid information screening is completed, the rest of the valid information is split into the face element and the labeling information contained in the text element.
The processing of the face element mainly comprises fuzzy matching of the face element according to the layer name and fuzzy matching of the face element according to the filling color. In the fuzzy matching process of the map layer names according to the map layer names, fuzzy matching is carried out on the map layer names of the map layers where the face elements are located and standard land names specified by urban and rural planning standards to obtain the standard land names of the face elements, and then three-level classification is carried out on the standard land names of the face elements according to land division rules specified by the urban and rural planning standards to obtain the land types of the face elements. And in the process of carrying out fuzzy matching on the face element filling color according to the filling color, carrying out fuzzy matching on the face element filling color and the standard filling color specified by the urban and rural planning standard to obtain the standard filling color of the face element, and further carrying out three-level classification on the standard filling color of the face element according to the land division rule specified by the urban and rural planning standard to obtain the land category of the face element. And the land type of the face element obtained by fuzzy matching according to the layer name is cross-compared with the land type of the face element obtained by fuzzy matching according to the filling color, and the land type of the face element is adjusted by combining the land type division results of the land type and the land type.
The method mainly comprises the steps of carrying out standardization processing on the fields contained in the label information aiming at the label information, and correcting the land categories of the face elements according to the standardized label information to obtain corrected land categories of the face elements.
And further, the standardized information mapping processing is performed on the corrected land type of the face element. In the process of mapping standardized information, corresponding standard fields are established according to corrected land categories of the face elements, standard information such as the standard fields and standardized marking information is filled, and mapping is established between the filled standard information and the corresponding face elements. And finally outputting the surface elements according to the mapped standard information to obtain the urban and rural planning drawing of the ground elements for standardization.
