Generally, the layout planning drawings of the building standard floorbar drawing and the basement are required to be opened simultaneously, whether errors or flaws exist in the layout of the basement is judged through side-by-side display or two display screens, if the two drawings are overlapped, the lines in the layout planning drawings of the basement cannot be clearly compared due to too many lines in the building standard floorbar drawing, each layer or line in the building standard floorbar drawing can only be processed in advance through manpower, then the manually processed drawing surface is compared with the layout planning drawings of the basement, the work is not only tedious, errors are easy to occur when different layers are compared through the manpower, and time cost and labor cost are high.
In order to solve the above technical problem, an embodiment of the present application provides a method for automatically obtaining a building projection line, which is shown in fig. 1 and includes steps S1 to S4.
Specifically, step S1: according to the standard floor column diagram of the building, the drawing with different attributes is automatically identified, and the drawing with different attributes at least comprises a column drawing, a window drawing and a wall drawing.

And step S4: and loading the projection line in the building projection line drawing surface into other floor drawing surfaces to determine the range of the projection line in the other floor drawing surfaces, and checking the other floor drawing surfaces according to the projection line and a preset rule.
In this embodiment, the building standard floor refers to a floor with the same plane layout, that is, the building standard floor can share one drawing for construction, and usually appears in a high-rise building. The first floor and the top floor of the building are standard floors provided that the space division of the first floor and the top floor is the same as that of the other floors. In practice, the first floor has a building entrance and exit, the top floor has a water tower, and the ground reservoir has an underground garage, so the standard floor is usually the floor except the first floor, the top floor and the ground reservoir. Functional spaces such as a water pump room, a garbage disposal room and a power transformation room can be generally arranged in the ground reservoir except for parking spaces, however, if the functional spaces are not properly arranged, inconvenience in life of a user can be caused, for example, living space of the user is arranged above the water pump room, and low-frequency noise generated by the water pump in the operation process can influence the user.
In this embodiment, in step S1, drawing surfaces with different attributes are automatically identified according to the building standard floorbar graph, and the drawing surfaces with different attributes at least include: pillar, window, and wall drawing. The building standard layer column diagram refers to a structural Drawing of a building standard layer, and may be, for example, a Drawing drawn by an engineer sampling CAD and stored in a preset format, where the preset format may be DWG (Drawing), and the embodiment of the present disclosure does not limit this.
In this embodiment, after obtaining the drawing of the building standard floor column diagram in advance, the ODA (Open Design Alliance) may be used to analyze the two-dimensional drawing with the preset format to obtain the relevant data of the building standard floor column diagram; then, drawing with different attributes is automatically identified from the related data of the building standard floor column diagram. Such as a pillar drawing, window drawing, and wall drawing. Furthermore, the drawings with different attributes can further comprise: beam drawings, door drawings, and the like. For example, the drawing of automatic identification different attributes can be discerned according to the relevant data in the building standard floor column diagram, for example, can predetermine the rule according to the lines of building standard floor column diagram and discern, and more closely one step, because the length of its lines of drawing of different attributes, width etc. are generally also different, and this application can set up different lines according to different building standard floor column diagrams and predetermine the rule, then predetermine rule discernment column diagram face, window drawing and wall drawing etc. according to the lines. In this embodiment, rule is predetermine according to the lines of the building standard floor column diagram of difference and is discerned, can make the picture of different attributes discern more accurate, and is favorable to promoting recognition efficiency.
In this embodiment, in step S2, the pillar drawing, the window drawing and the wall drawing are superimposed, and the building projection drawing is formed by enclosing the pillar drawing, the window drawing and the outermost line of the wall drawing. Specifically, the number of column drawing faces, window drawing faces and wall drawing faces in the building standard storey column drawing can be respectively identified according to line preset rules, then the number of the column drawing faces, the number of the window drawing faces and the number of the wall drawing faces are compared with the preset number, column drawing faces, window drawing faces and wall drawing faces which obviously do not accord with the preset number are removed and are identified again, wherein the obvious quantity which does not accord with the preset number can be understood as being more than 2 times or more than the preset number, then the column drawing faces, the window drawing faces and the outermost line of the wall drawing faces are enclosed according to the enclosed result, and the number of the column drawing faces, the window drawing faces and the wall drawing faces is adjusted to obtain the building projection line drawing face.
In this embodiment, step S2 further includes: and superposing the column drawing surface, the window drawing surface and the wall drawing surface, and identifying or superposing again if part of the column drawing surface, the window drawing surface or the wall drawing surface is superposed at the same position after superposition, wherein any one of the column drawing surface, the window drawing surface and the wall drawing surface can be rotated and superposed.
In this embodiment, in step S3, the pillar in the building projection line drawing is used as the identification point, the pillar position in the building projection line drawing is matched with the pillar position in the floor drawing of another floor, and if the pillar positions in the two pillar drawings can be matched correspondingly, the pillar coordinate is used as the anchor point; it should be noted that two bar graphs refer to a bar graph in the building projection line graph and a bar graph in the floor graph of another floor. If the positions of the columns in the two column diagrams cannot be matched, symmetrically judging the building projection line drawing surface and other floor drawing surfaces or rotationally offsetting the other floor drawing surfaces until the positions of the columns in the two column diagrams are matched. For example, when there are a plurality of bar graphs in the projection line graph of the building, one of the bar graphs is first used as the identification point, and then the position of the bar graph is matched with the position of the bar graph in the floor graph (e.g., the basement) of other floors, because the positions of the bar graphs (the cylinder graphs) are consistent (e.g., the standard floors and the basement) although the layout ways of different floors are different. Therefore, the column diagram is used as the identification point, and the comparison work of different floors can be completed more efficiently.
In this embodiment, if the positions of the cylinders in the two cylinder diagrams can be matched correspondingly, for example, comparison position points may be preset in the two cylinder diagrams, and the cylinders in the two cylinder diagrams are compared, as long as the comparison position points in the two cylinder diagrams can be in one-to-one correspondence, for example, the features of the comparison position points are the same, it is described that the positions of the cylinders in the two cylinder diagrams can be matched correspondingly, and then the coordinates of the cylinders in the cylinder diagrams are used as anchor points, that is, reference points. When the column positions in the two column diagrams cannot be matched, it can be understood that when the number of the comparison position points in the two column diagrams is different exceeds the preset number, the column positions in the two column diagrams cannot be matched. At this time, the building projection line drawing surface and other floor drawing surfaces can be symmetrically judged, for example, the building projection line drawing surface can be rotated by 180 degrees to judge whether the building projection line drawing surface is used correctly.
In this embodiment, when the positions of the pillars in the two bar graphs cannot be matched, the other floor graphs can be rotationally shifted. For example, the other floor drawings can be rotated and shifted by 15 ° counterclockwise each time, and the above-mentioned matching of the building projection line drawing with the column positions in the floor drawings of other floors is repeated until the column positions in the two columns are completely matched. In an embodiment, matching can be completed more efficiently by matching other floor drawings with the column diagram in the building projection line drawing by rotating and offsetting 15 degrees anticlockwise every time so as to determine the position of the column.
In this embodiment, in step S4, the projection line in the building projection line map is loaded into another floor map to determine the range of the projection line in the another floor map, and the another floor map is checked according to the projection line and the preset rule. Specifically, after the anchor point is determined, the projection line in the building projection line drawing is loaded to the drawing of other floors to judge whether the layout of other floors is proper. For example, there is no living space above the water pump room in the ground reservoir, so as to prevent the low-frequency noise generated by the water pump during the operation from possibly affecting the user.
In one particular embodiment, the bar graph may include: frame pole diagrams, conversion pole diagrams, stem pole diagrams, wall pole diagrams, and the like. The selection can be made according to the proportion occupied by or the position of the frame pole diagram, the conversion pole diagram, the core pole diagram and the wall pole diagram in different buildings.
In one embodiment, referring to fig. 2, in step S1, the method for automatically identifying the drawing with different attributes includes: step S11 and step S12.
And S11, acquiring attribute labels of different lines in the standard storey pillar diagram of the building.
Specifically, the widths, lengths and cross sections of different lines in the building standard storey column diagram are respectively and correspondingly compared with the preset widths, preset lengths and preset cross sections one by one, and attribute labels corresponding to the different lines are given according to the comparison result.
And S12, separating the lines in the same attribute label, and obtaining a column drawing surface, a window drawing surface and a wall drawing surface according to the attribute labels and the screening rules of the different lines.
The screening rule can be set according to position information corresponding to the column drawing surface, the window drawing surface and the wall drawing surface, and the positions of the column drawing surface, the window drawing surface and the wall drawing surface in the building are generally different. For example, the column drawing is generally located at a peripheral position of a building, the wall drawing is generally located at a central position of the periphery of the building, and the wall drawing may be located at any position of the building, and then the determination is performed according to the number of attribute tags, types of the attribute tags, and position information corresponding to the column drawing, the window drawing, and the wall drawing, which are required by the column drawing, the window drawing, and the wall drawing, so that the column drawing, the window drawing, and the wall drawing can be accurately determined.
In one embodiment, in step S2, the method for enclosing the outermost lines of the pillar drawing, the window drawing and the wall drawing comprises: and (3) overlapping the column drawing surface, the window drawing surface and the wall drawing surface, then enclosing with the outermost periphery lines, firstly enclosing the line segments with parallel relation and intersected extension lines, if not, enclosing the line segments with intersected relation and perpendicular relation, judging the exterior lines of the building after enclosing, and deleting the exterior lines of the building.
Specifically, in step S2, after the pillar drawing, the window drawing and the wall drawing are superimposed, the outermost line is determined according to the attribute labels of the different lines and the position information of the different lines, and then the outermost line is used for enclosing.
In one embodiment, in step S2, the method for determining the building exterior line includes, when the line is outside the outermost periphery line, re-determining whether the building exterior line belongs to one of the obtained bar graph drawing, window drawing and wall drawing according to the attribute tag and the screening rule of the building exterior line, if so, re-performing enclosure according to the outermost periphery line of the bar graph drawing, window drawing and wall drawing to form the building projection line drawing, otherwise, deleting the building exterior line. Therefore, the purpose of picking up the building projection line is achieved, and the formed building projection line is cleaner and tidier.
In one embodiment, step S2 further comprises: forming an axis grid drawing according to the standard floor column drawing of the building; the axis is the axis of the wall body in the wall drawing surface, the axis of the wall body is extended to form an axis grid, and the axis grid is separated from the building standard storey column drawing to form an axis grid drawing surface.
Specifically, the central axis of the wall body in the wall drawing is determined, the axis is determined according to the central axis, and the central axis of the wall body is extended to form an axis grid. It will be appreciated that the axis of the wall may be extended to intersect the outermost peripheral lines to form an axis grid, and then the axis grid may be separated from the standard storey pillar diagram of the building to form an axis grid map. For example, the position information of the axis grid can be obtained according to the position information of the central axis of the wall body, and the axis grid is separated from the building standard storey pillar diagram according to the position information of the axis grid to form an axis grid drawing.
In one embodiment, step S3 further comprises: and overlapping the axis grid drawing with the building projection drawing, and determining the coordinates of the cylinder according to the relative position relationship between the axis in the axis grid drawing and the cylinder in the building projection drawing.

In this embodiment, after the axis grid drawing and the building projection drawing are superimposed, the axis grid drawing is matched with other floor drawings (for example, a ground library), and then the axis and the cylinder coordinate are matched with the cylinders in other floor drawings correspondingly, for example, it can be judged according to the axis whether the cylinder coordinate is different from the positions of the cylinders in other floor drawings, and if the cylinder coordinate is the same as the position of the cylinder in other floor drawings, matching is completed. In the embodiment, the axis mainly plays a role in auxiliary recognition, the axis refers to a grid formed by extending the center axis of the wall body, when the ground library is recognized, the wall body cannot be directly recognized through the wall body, and good auxiliary correspondence can be played through the axis.
In one embodiment, the filtering rule in step S12 includes: selecting lines enclosed into a block shape and parallel lines from the lines with the wall attribute labels; selecting lines meeting a preset width and lines parallel to the wall attribute lines from the lines with the window attribute labels; and selecting lines which enclose into a block shape and lines which accord with a preset width from the lines with the column attribute labels.

The integration module 52 performs enclosure according to the bar chart surface, the window chart surface and the outermost lines of the wall chart surface, and performs adjustment according to the enclosure result and the number of the bar chart surface, the window chart surface and the wall chart surface to obtain the building projection line chart surface.
In this embodiment, the integration module 52 is further configured to superimpose the pillar drawing surface, the window drawing surface, and the wall drawing surface, and if a part of the pillar drawing surface, the window drawing surface, or the wall drawing surface is superimposed at the same position after superimposing, the recognition is performed again.
In this embodiment, the matching module 53 is configured to use a pillar map in the building projection line map as an identification point, match the building projection line map with the pillar map positions in the floor maps of other floors, and if the pillar positions in two pillar maps can be correspondingly matched, use the pillar coordinates as an anchor point; if the positions of the columns in the two column diagrams cannot be matched, symmetrically judging the building projection line drawing surface and other floor drawing surfaces or rotationally offsetting the other floor drawing surfaces until the positions of the columns in the two column diagrams are matched. For example, when there are a plurality of bar graphs in the projection line graph of the building, one of the bar graphs is first used as the identification point, and then the position of the bar graph is matched with the position of the bar graph in the floor graph (e.g., the basement) of other floors, because the positions of the bar graphs (the cylinder graphs) are consistent (e.g., the standard floors and the basement) although the layout ways of different floors are different. Therefore, the column diagram is used as the identification point, and the comparison work of different floors can be completed more efficiently.
In this embodiment, if the positions of the cylinders in the two bar graphs can be correspondingly matched, for example, comparison position points may be preset in the two bar graphs, and the cylinders in the two bar graphs are compared, as long as the comparison position points in the two bar graphs can be in one-to-one correspondence, for example, the features of the comparison position points are the same, it is described that the positions of the cylinders in the two bar graphs can be correspondingly matched, and then the coordinates of the cylinders in the bar graphs are used as anchor points, that is, reference points. When the column positions in the two bar graphs cannot be matched, it can be understood that when the number of the comparison position points in the two bar graphs is different exceeds the preset number, the column positions in the two bar graphs cannot be matched. At this time, the building projection line drawing can be symmetrically judged with other floor drawing, for example, the building projection line drawing can be rotated by 180 ° to judge whether the building projection line drawing is used correctly.
In this embodiment, when the positions of the pillars in the two pillars cannot be matched, the other floor drawings may be rotationally shifted, for example, the other floor drawings may be rotationally shifted by 15 ° counterclockwise each time, and the above-mentioned matching of the projection line drawing of the building with the positions of the pillars in the floor drawings of the other floors is repeated until the positions of the pillars in the two pillars are matched. In an embodiment, matching can be completed more efficiently by matching other floor drawings with the column diagram in the building projection line drawing by rotating and offsetting 15 degrees anticlockwise every time so as to determine the position of the column.
In this embodiment, the checking module 54 is configured to load the projection line in the building projection line drawing surface into another floor drawing surface to determine the range of the projection line in the other floor drawing surface, and check the other floor drawing surface according to the projection line and a preset rule. Specifically, after the anchor point is determined, the projection line in the building projection line drawing is loaded to the drawing of other floors to judge whether the layout of other floors is proper. For example, there is no living space above the water pump room in the ground reservoir, so as to prevent the low-frequency noise generated by the water pump during the operation from possibly affecting the user.
