In the embodiment of the present application, an architectural drawing is taken as an example for explanation.
In a specific embodiment, as shown in fig. 2, the method for extracting the basic attribute from the construction drawing mainly includes:
The fortification intensity refers to the seismic intensity approved as a basis for seismic fortification of a region according to the national regulation authority. The earthquake-resistant grade is determined by design departments according to national relevant regulations, building importance classification and fortification standards and four factors of fortification categories, structure types, intensity and house height, and is specifically designed by adopting different earthquake-resistant grades. Taking a reinforced concrete frame structure as an example, the earthquake resistance grade is divided into four grades from one grade to four grades to represent four grades of serious, serious and general. Structural systems refer to the way in which structures are built up against external influences. The main types of the structural system include a brick concrete structure, a steel structure and the like, wherein the main types of the concrete structure include a frame structural system, a shear wall structural system, a frame-shear wall structural system and the like.
In one embodiment, the extracting project information and the floor height table from the construction drawing comprises: searching project information from a structural general description drawing and a drawing frame of an edge member through text matching; from the wall plan, the story height table is extracted.
For example: in the structural general description drawing, a text of 'fortification intensity' is searched through a regular matching text, and specific data corresponding to the 'fortification intensity' is obtained around the text of the 'fortification intensity'.
The edge member details are typically in the form of a table having at least 5 rows, each row representing a "section", "number", "stirrup", "longitudinal bar" and "elevation", respectively. Information in a cell indicating a "section" is section information, and a section diagram of an edge member, label information, a diagram of a stirrup and a longitudinal bar, and the like are usually included in the section information, the stirrup is usually indicated by a line segment, and the longitudinal bar is usually indicated by a circle; the information in the cell indicating "number" is a number, which is the number of the edge member, for example, AZ 1; the information in the cells representing the "stirrups" is a stirrup text, for example, the stirrup text is phi 10@100, the diameter of the stirrup is 10mm, and the distance between the stirrups is 100 mm; the information in the cell indicating the "longitudinal bar" is a longitudinal bar text, for example, the longitudinal bar text is 6 Φ 16, the number of the longitudinal bars is 6, and the diameter of the longitudinal bars is 16 mm; the information in the cell indicating "elevation" is the elevation, and for example, the elevation is 11.050 to 53.050, and the elevation is 11.050 to 53.050 m.
Since only the original primitives such as line segments, texts, circles, etc. can be analyzed in the CAD drawing, and the whole table, each cell in the table, and the meaning of each cell cannot be identified, the following specific embodiment describes in detail how to extract the information of the edge component detail drawing from the construction drawing.
In one embodiment, extracting information about details of the edge member from the construction drawing includes: identifying the layer where the table line of the edge member detail drawing is located; identifying cells in the table of edge member detail map by converting the table of edge member detail map into a picture and looking up the inner contour; and determining the meaning of each unit cell by identifying the primitive information in each unit cell in the layer, wherein the primitive information comprises a line segment, a text and a circle, and the meaning comprises one of section information, a number, a stirrup text, a longitudinal bar text and a height.
The layer where the table line of the edge member detail drawing is located can be identified by identifying the layer where the table line of the edge member detail drawing is located, wherein the table line can be any table line in the edge member detail drawing whole table, can be an inner frame line, and can also be an outer frame line. The identification of the cells in the table of the detail view of the edge member by converting the table of the detail view of the edge member into a picture and looking up the inner contour can be realized by OpenCV (a cross-platform computer vision and machine learning software library), which can identify each cell in the table of the detail view of the edge member. Determining the meaning of each cell by identifying primitive information in each cell in the layer, for example: recognizing that the graphic element information in the cell has a symbol phi, a symbol @ and a number, and determining that the cell means a stirrup text; and recognizing that the primitive information in the cell comprises line segments, circles and texts, and then the cell means the section information. The meaning of each cell is determined by identifying the primitive information in each cell in the layer, and the problem of inaccurate meaning of the cell caused by table serial can be avoided compared with the method that the meaning of each row of cells is determined by matching keywords including 'section', 'serial number', 'stirrup', 'longitudinal bar' and 'elevation' through texts.
In one embodiment, identifying the layer where the table lines of the detail view of the edge member are located includes: finding a stirrup text in a picture frame of a detailed picture of the edge member through text matching; obtaining coordinates of each stirrup text, and comparing the coordinates of each stirrup text to obtain two stirrup texts with the nearest distance; generating a circumscribed rectangle according to the coordinates of the two hoop text with the closest distance; and acquiring a line segment passing through the external rectangle, and acquiring a layer where the line segment passing through the external rectangle is located, wherein the layer where the line segment passing through the external rectangle is located is the layer where the table line of the detailed graph of the edge member is located. The line segment passing through the external rectangle is the table line shared by the two cells where the two hoop texts with the shortest distance are located, and the layer where the line segment passing through the external rectangle is the layer where the table line of the detailed graph of the edge member is located.
In addition, two nearest stirrup texts can be obtained, two nearest longitudinal bar texts can be obtained, two nearest elevations can be obtained, or one stirrup text and one longitudinal bar text can be obtained, as long as the coordinates of the contents of two adjacent cells can be obtained, a circumscribed rectangle is generated according to the coordinates of the contents of the two adjacent cells, and a line segment passing through the circumscribed rectangle is obtained, namely the line segment is the table line shared by the two adjacent cells. Therefore, the protection scope of the present application is not limited by the specific contents of the two adjacent cells.
The table of the story height is generally in the form of a table having at least 4 columns, each column representing "story number", "story height", "elevation" and "concrete strength grade", respectively. For example: in the information of the detailed drawing of the edge member, the elevation is 8.970-20.970, the layer number corresponding to the elevation 8.970 is found to be 4 through text matching from the layer height table, the layer number corresponding to the elevation 20.970 is 8, the elevation is equivalent to the ground height of each layer, so the elevation is 8.970-20.970 equivalent to the height of 4-7 layers of buildings, the corresponding layer number is 4-7 layers, the layer height corresponding to the layer number 4-7 layers is found to be 3.00 through text matching from the layer height table, and the concrete strength grade is C35.
And 102, calculating primary attributes of the edge member according to the basic attributes, wherein the primary attributes comprise longitudinal bar information, stirrup information and the section profile of the edge member.
The longitudinal bar information comprises the number and the diameter of the longitudinal bars. The stirrup information includes the diameter, spacing and length of the stirrups.
In a specific embodiment, as shown in fig. 3, the method for calculating the primary attribute of the edge component according to the basic attribute mainly includes:
In a specific embodiment, the diameter and the distance of the stirrups are extracted from the stirrup text, and the number and the diameter of the longitudinal bars are extracted from the longitudinal bar text, including: searching phi and @ in a stirrup text through text matching, wherein the text between phi and @ in the stirrup text is the diameter of a stirrup, and the text behind @ in the stirrup text is the distance of the stirrup; and searching phi in the longitudinal bar text through text matching, wherein the text in front of phi in the longitudinal bar text is the number of longitudinal bars, and the text behind phi in the longitudinal bar text is the diameter of the longitudinal bars.
For example: the text of the stirrup in the information of the detail drawing of the edge member is phi 10@100, the text 10 between phi and @ in the text of the stirrup is the diameter of the stirrup, the diameter of the stirrup is 10mm, the text 100 behind the phi in the text of the stirrup is the distance between the stirrups, and the distance between the stirrups is 100 mm; the text 6 in front of phi in the longitudinal bar text is the number of longitudinal bars, which means that the number of longitudinal bars is 6, the text 16 behind phi in the longitudinal bar text is the diameter of the longitudinal bars, and the diameter of the longitudinal bars is 16 mm.
Since only the original primitives such as line segments, texts, circles, etc. can be analyzed in the CAD drawing, and the cross-sectional profile of the edge member cannot be identified, the following embodiment describes in detail how to extract the cross-sectional profile of the edge member from the cross-sectional information.
In one embodiment, extracting the cross-sectional profile of the edge member from the cross-sectional information comprises: acquiring coordinates of two end points of each line segment in the section information; and splicing the line segments with the end points with the same coordinate to form a closed space, wherein the closed space is the edge member, and the line segments with the end points with the same coordinate are the section outline of the edge member. For example: the cross-sectional profile of the edge member is L-shaped or T-shaped, etc.
Because each line segment in the section information is not provided with line segment length marking information, and if the line segment length marking information is used when parameters such as the section outline area of the edge component and the like are calculated, the line segment length marking information of each line segment needs to be searched first, which is complicated and easy to make mistakes, the actual calculation is generally carried out according to the actual line segment length and the drawing proportion on the CAD drawing. Therefore, the following embodiment describes in detail how the drawing scale is calculated.
In one embodiment, calculating the plot ratio comprises: acquiring line segment length marking information of the cross-sectional profile of the edge component; acquiring the actual length of a line segment of the cross-sectional profile of the edge member; and calculating the drawing proportion according to the actual length of the line segment and the length marking information of the line segment.
Wherein, the segment length marking information of the cross-sectional profile of the edge member is obtained by obtaining the end point coordinates of each segment in the cross-sectional profile of the edge member, obtaining the maximum abscissa value, the minimum abscissa value, the maximum ordinate value and the minimum ordinate value in the end point coordinates, forming a circumscribed rectangle of the cross-sectional profile of the edge member according to the maximum abscissa value, the minimum abscissa value, the maximum ordinate value and the minimum ordinate value, forming a new circumscribed rectangle after the circumscribed rectangle of the cross-sectional profile of the edge member is extended by adding the maximum abscissa value to the preset value, subtracting the preset value from the minimum abscissa value, adding the preset value to the maximum ordinate value and subtracting the preset value from the minimum ordinate value, the segment length marking information of the cross-sectional profile of the edge member is contained in the new circumscribed rectangle, and obtaining a pure digital text inside the new circumscribed rectangle, namely the line segment length marking information of the cross-sectional profile of the edge component. The actual length of the line segment of the cross-sectional profile of the edge member can be directly obtained from the CAD drawing. For example: the actual length of the line segment is 800mm, the length marking information of the line segment is 200, and the drawing proportion is 4: 1.
And step 303, extracting the stirrups and the longitudinal bars from the section information, and calculating the lengths of the stirrups.
In one embodiment, extracting the stirrups and the longitudinal bars from the section information includes: searching a line segment inside the cross-sectional profile of the edge member, wherein the line segment inside the cross-sectional profile of the edge member is the stirrup; and searching a circle inside the cross-sectional profile of the edge member, wherein the circle inside the cross-sectional profile of the edge member is the longitudinal rib.
If there are multiple instances of the band text in a cell representing a "band" in the detail view of the edge member, the inner band and the outer band are distinguished, typically with a bracket placed behind the band text, the bracket indicating either the inner band or the outer band. In this case, it is necessary to determine the positions of the inner band and the outer band in the cross-sectional information, and a stirrup line segment parallel to and closest to the cross-sectional profile of the edge member is the outer band, and another stirrup line segment inside the cross-sectional profile of the edge member is the inner band.
Because the stirrup line segment in the section information only indicates the position of the stirrup in the edge member, the actual line segment length of the stirrup line segment in the section information has no proportional relation with the actual length of the stirrup, and the actual length of the stirrup cannot be calculated through the actual line segment length and the drawing proportion of the stirrup line segment in the section information. Moreover, a certain distance exists between the stirrup line segment in the section information and the section outline of the edge member, concrete at the distance is called a protective layer, the thickness of the protective layer on the CAD drawing and the actual thickness of the protective layer have no proportional relation, so that the actual length of the stirrup line segment in the section information and the actual length of the stirrup have no proportional relation, and the actual length of the stirrup line segment in the section information cannot be deduced according to the actual length of the stirrup line segment in the section information. Thus, the following specific example details how the actual length of the stirrup is calculated.
In one embodiment, calculating the length of the stirrup includes: extending the stirrup line segment in the section information to two end points of the stirrup line segment on the section outline of the edge member to obtain a new stirrup line segment; acquiring the actual length of the line segment of the new stirrup line segment; and calculating the length of the stirrup according to the actual length of the line segment of the new stirrup line segment, the thickness of the protective layer and the diameter of the stirrup.
The stirrup line segment in the cross-sectional information is parallel to one line segment in the cross-sectional outline of the edge member, the stirrup line segment in the cross-sectional information is extended to two end points of the stirrup line segment and is positioned on the cross-sectional outline of the edge member, and a new stirrup line segment is obtained, so that the new stirrup line segment is parallel to one line segment in the cross-sectional outline of the edge member and has the same length. The actual length of the new stirrup line segment can be directly obtained from the CAD drawing. The length of the stirrup is calculated according to the actual length of the line segment of the new stirrup line segment, the thickness of the protective layer and the diameter of the stirrup, specifically, the length of the new stirrup line segment represented in the entity building can be calculated according to the actual length of the line segment of the new stirrup line segment and the drawing proportion, the length of the new stirrup line segment represented in the entity building is subtracted by the thickness of the protective layer which is twice the thickness of the protective layer, and then the diameter of the stirrup is subtracted, so that the length of the stirrup is the length of the stirrup. The protective layer thickness may be obtained from a frame of edge members. The protective layer is the distance from the surface of concrete to the outer edge of the nominal diameter of the outermost steel bar of the concrete member, wherein the protective layer is the part of the concrete which protects the steel bars from being directly exposed. Since the outer hoop is wound once, when calculating the length of the stirrup, the length represented by the new stirrup segment in the solid building needs to be subtracted by twice the radius of the stirrup, i.e. by the diameter of the stirrup, in addition to the twice the thickness of the protective layer.
And 103, calculating secondary attributes of the edge member according to the basic attributes and the primary attributes, wherein the secondary attributes comprise the section profile area, the reinforcement ratio and the hoop ratio of the edge member.
In a specific embodiment, as shown in fig. 4, the method for calculating the secondary attribute of the edge component according to the basic attribute and the primary attribute mainly includes:
The coordinates of the end points of each line segment in the cross-sectional profile of the edge member are the coordinates of the corner points of the cross-sectional profile of the edge member. According to the corner point coordinates, the shape of the cross-sectional profile of the edge member can be judged, and then the area of the cross-sectional profile of the edge member is calculated.
The reinforcement ratio is the ratio of the area of the longitudinal reinforcement in the edge component to the area of the cross section profile of the edge component, the reinforcement ratio is a parameter influencing the stress characteristic of the edge component, the damage form of the normal cross section of the edge component can be controlled by controlling the reinforcement ratio, and the damage of excessive reinforcement and the damage of less reinforcement can not occur. The hoop distribution rate is used for reflecting the content of the stirrup relative to concrete, the volume distribution rate and the area distribution rate, the hoop distribution rate is a main factor influencing the shearing bearing capacity of the edge member, and the damage form of the oblique section of the edge member can be controlled by controlling the hoop distribution rate, so that the edge member is free from oblique pull damage and oblique pressure damage.
And 104, packaging the basic attribute, the primary attribute and the secondary attribute to generate an edge component object.
And carrying out data structured packaging on the basic attribute, the primary attribute and the secondary attribute through an object-oriented Python language to generate an edge component object.
