In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of 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.
In consideration of the mode that only the primitive library in the local configuration data of the background server is used as the standard primitive and the primitive identification is carried out on the drawing to be processed through the standard primitive, the problem that the primitive library of the background server is inconsistent with the primitive used in the drawing to be processed exists. The embodiment of the invention provides a standard primitive determining method, a primitive identifying method, a device and electronic equipment.
To facilitate understanding of the present embodiment, first, a method for determining a standard primitive disclosed in the present embodiment is described in detail, as shown in fig. 1; the method comprises the following specific steps:
and step S102, analyzing the drawing submitted by the user to obtain drawing information.
The drawings typically include tables, text data corresponding to the tables, and the like. In specific implementation, a user may draw a table by using a CAD (Computer Aided Design) and fill text data in the table, and may draw the table by using a table object carried by the CAD, and may also draw the table by using discrete line segments and text.
Usually, a drawing drawn by a user can be read from the background data of the CAD, and the drawing information can be analyzed by analyzing the drawing. The drawing information typically includes text data, and graphic attributes, which typically include lines, circles, rectangles, arcs, ellipses, fills, line shapes, line widths, colors, fonts, and the like. The table in the drawing is usually obtained by the graphic attribute.
Step S104, obtaining a legend description table corresponding to the drawing based on preset local configuration data and the drawing information; the legend table includes textual description information.
The preset local configuration data is usually stored in a local configuration file of the server, and the local configuration data usually stores service fields expressed in a legend description table, where the service fields are usually description information for different services, and the services may be legends formed by straight lines, rectangles, and the like.
By matching the drawing information with the local configuration data, it can be determined whether the drawing includes a legend table, and usually, a table in the drawing matched with the local configuration data is determined as the legend table.
Step S106, judging whether the text description information is matched with the service attribute description in the local configuration data.
The service attribute description generally refers to that in local configuration data of a service end, different legends are all identified by text description, for example, a legend service composed of a straight line is described as a high-voltage line.
Judging whether the text description information corresponding to the graphic element in the drawing has a mapping relation with the service attribute description in the local configuration data, judging whether the text description information is matched with the service attribute description in the local configuration data, and if the mapping relation exists, matching the text description with the service attribute description; if no mapping relation exists, no subsequent operation is carried out.
And step S108, if the primitive features are matched, extracting the primitive features corresponding to the legend description table to obtain a standard primitive.
Firstly, extracting the primitives stored in the table of the drawing, and then extracting the characteristics of the primitives according to the legend description table to obtain the characteristics of the primitives. The primitive features generally include: text description information, combined base graphic information, graphic attribute information, graphic profile information, graphic matrix information, and the like. And corresponding the primitive features to the primitives to obtain standard primitives.
In a specific implementation, if the graphic description information of the primitive corresponding to the legend table matches with the service attribute description in the local configuration data, the mapping is performed automatically. In the mapping process, the text description information of the primitive corresponding to the legend explanatory table of the design unit of each region can be mapped with the service attribute description in the local configuration data, so that the standard primitive which can be suitable for each region is obtained, and the accuracy and the recognition rate of primitive recognition in the drawing can be improved.
The invention provides a method for determining a standard primitive, which comprises the steps of firstly analyzing a drawing submitted by a user to obtain drawing information; obtaining a legend description table corresponding to the drawing based on preset local configuration data and drawing information; judging whether the text description information in the legend table is matched with the service attribute description in the local configuration data; and if the primitive features are matched, extracting the primitive features corresponding to the legend table to obtain the standard primitive. The method extracts the primitive features of the legend table corresponding to the drawing, determines the standard primitive through the primitive features and the local configuration data, can dynamically determine the standard primitive according to different drawings, and improves the recognition rate of the primitive in the drawing compared with the traditional method for recognizing the primitive through the local configuration data.
The embodiment of the invention also provides another method for determining the standard primitive, which is realized on the basis of the method of the embodiment; as shown in fig. 2, the method comprises the steps of:
step S202, acquiring a drawing submitted by a user.
And step S204, determining a cell based on the line segment in the drawing.
Firstly, extracting all vertical line segments and horizontal line segments in a drawing, and then intersecting all the extracted vertical line segments and horizontal line segments to obtain an intersection point. And obtaining a cell according to the intersection point and the line segment.
Step S206, determining a form corresponding to the drawing and text data corresponding to the form according to the position relation of the cells; and determining the table and the text data corresponding to the table as drawing information.
In the concrete implementation, the position relation of the cells is utilized to combine the cells which are on the same side and adjacent to each other into a cell row, and the cell rows which are adjacent to each other up and down are combined into a table.
And step S208, reading the text data of each table corresponding to the drawing.
The drawing usually includes one or more tables, and according to the position coordinates of the cells corresponding to each table, the text data corresponding to the position coordinates can be located, and the text data is determined as the text data corresponding to each cell, so as to obtain the text data corresponding to each table.
Step S210, judging whether the text data is matched with a service field in the local configuration data; if yes, go to step S212; otherwise, ending.
The service field is usually a regular expression constructed according to different service (e.g., legend service) data, wherein the regular expression is usually a logic formula corresponding to the different service data. In specific implementation, text data corresponding to each table is circularly traversed, whether the text data is matched with the regular expression or not is judged according to each text data, if the text data is matched with the regular expression, a legend description table is determined to be found, if the text data is not matched with the regular expression, a corresponding legend description table is not found, the process of constructing a standard legend is finished, and at the moment, when a primitive in a drawing is identified, a primitive pair of local configuration data is usually extracted to identify the primitive in the drawing.
Step S212, determining the table corresponding to the text data matched with the service field as a legend table.
Step S214, check whether the text description information of the primitive in the legend table matches the text description information of the primitive in the local configuration data.
The text description information of the primitive in the local configuration data may be understood as the service attribute description, and the service attribute description further includes a service identifier corresponding to the text description information of the primitive. The service identifier is usually an identifier that describes a text for a different legend, for example, a legend service composed of a straight line is described as a high-voltage line.
Step S216, if the two are matched, mapping the text description information and the service attribute description in the local configuration data to obtain a service identifier corresponding to the primitive in the legend table; the service attribute describes a service identifier corresponding to text description information of a primitive in the local configuration data.
In step S218, the primitive features corresponding to the legend table are extracted to obtain the standard primitive.
In particular implementations, step S218 is generally implemented by steps 10-11 as follows:
step 10, extracting the primitive from the table corresponding to the illustration table.
And 11, traversing each primitive to obtain primitive characteristics, namely obtaining text description information corresponding to each primitive.
In specific implementation, after a standard primitive is obtained, the standard primitive is set to be in a high priority level, and local configuration data is set to be in a secondary priority level.
The first standard of drawing by the user is from the legend description table and the primitive information which is preferentially identified by the legend, so that the identification rate of the primitives in the drawing can be effectively improved by setting high priority, wherein the identification of the priority is mainly whether the current standard primitive is loaded with local configuration data or the legend description table.
In specific implementation, the local configuration data can be extracted according to the primitive features to obtain corresponding primitive information, so that the primitive information can be used as a basis for primitive identification.
In the method for determining the standard primitive, since the design drawing of each region has the legend description table for describing the legend used in the current drawing frame, and the legend in the legend description table is the first standard for drawing the drawing by the user, the legend in the legend description table is used as the standard primitive in the method, so that the recognition rate of primitive recognition can be effectively improved.
The embodiment of the invention also provides a primitive identification method, which is realized on the basis of the method of the embodiment; as shown in fig. 3, the method comprises the steps of:
and step S302, acquiring a drawing to be processed.
Step S304, judging whether a standard primitive exists or not; the standard primitive is obtained by a method for determining the standard primitive; if yes, executing step S306; if not, step S308 is performed.
And step S306, identifying the graphic primitive in the drawing to be processed through the standard graphic primitive.
And step S308, identifying the graphic primitive in the drawing to be processed through preset local configuration data.
In specific implementation, the local configuration data can be extracted according to the primitive features to obtain corresponding primitive information, so that the primitive information can be used as a basis for primitive identification.
The primitive identification method comprises the steps of firstly obtaining a drawing to be processed, judging whether a standard primitive exists or not, and obtaining the standard primitive through a standard primitive determining method; if yes, identifying the graphic primitive in the drawing to be processed through the standard graphic primitive; otherwise, identifying the graphic primitive in the drawing to be processed through the preset local configuration data. The method preferentially identifies the primitive through the standard primitive, and can improve the identification rate of the primitive identification through identifying the primitive through the primitive information in the local configuration data under the condition that the standard primitive does not exist.
