Fig. 2 is a schematic structural diagram of a drawing according to an embodiment of the present application, and as shown in fig. 2, the drawing includes two plan views, which are a plan view 1 and a plan view 2 respectively. A field "standard layer 1 (underground second floor slab level construction drawing)" in which the word "figure" appears in the outer periphery of the plan view 1 may be determined as the plan view name of the plan view 1.

It should be noted that, as shown in fig. 2, the axes of the respective plan views in the present application are all transverse to the plan view, and the axis names of each axis are located at the end points of the axis. Thus, the "line having both end points located on the outer periphery of the plan view" can be identified as the axis, and the numeral labels located in the vicinity of the end points of the axis can be identified as the axis name pixels of the plan view.
And identifying the mutual positions of all lines, the character marks and the extending directions of all lines in the plane drawing so as to identify all component pixels of the plane drawing, and identifying the mark information pixels of all components of the plane drawing based on the number marks in a second preset distance on two sides of the longitudinal center line and/or the transverse center line of all components and/or parameter tables corresponding to all components.

Meanwhile, when an axis parallel to the wall line of the wall member is arranged around the wall member and the distance between the parallel wall line and the axis is smaller than a preset first maximum eccentric distance, arranging the wall member on the axis; when there is no axis around the wall element parallel to the wall line of the wall element, an axis is generated in the centre of the wall element.
The method of identifying a beam pixel of a plan view may include: the method includes the steps of identifying parallel beam lines in a plan view, determining to identify a beam member when a distance between a pair of the parallel beam lines is between a minimum beam width and a maximum beam width, determining a distance between the pair of the parallel beam lines as the beam width, and determining a plane position of the beam in the plan view based on a start point position and an end point position of the beam lines. Meanwhile, when an axis parallel to the beam line of the beam member is arranged around the beam member and the distance between the beam line and the axis is smaller than a preset second maximum eccentric distance, the beam member is arranged on the axis; when there is no axis around the beam member parallel to the beam line of the beam member, one axis is created in the center of the beam member.
The method of identifying door and window pixels of a plan view may include identifying a door and window opening in a plane of a wall member or identifying parallel door and window segments to identify a door member and a window member, and determining a position of a door and window in the plan view based on a position of the door and window opening or the parallel door and window segments in the plane of the wall member. The heights of the doors and the windows and the height of the windowsill can be obtained by parameter setting or by combining a facade diagram with door and window table recognition analysis.
Further, when identifying the pixels of the label information, the construction drawing of the structural profession, for example, the flat construction drawing of a beam, a column, a floor slab, and a shear wall, may be analyzed and identified according to the drawing expression rules in the "concrete structure construction drawing plane overall expression method drawing rules and structural detail drawing" of the national building standard design drawing set 16G101 to obtain the label information of each member, and the identification of the beam cross-sectional dimension is described below as an example.
Specifically, in the application, according to the content and the position of the section marking information in the DWG drawing, the associated beam sections (for example, a continuous beam and a beam span) can be automatically identified and found, and the section marking size information of the associated beam sections is determined and analyzed to obtain the size information (for example, the beam height and the beam width) of the beam member.
The method for analyzing the dimension information of the cross section of the associated beam section to obtain the dimension information of the beam member may specifically be: the cross-section dimension information corresponding to the beam member generally includes characters, such as X, or X, wherein the front value of the character is the beam width, and the rear value is the beam height, and the cross-section dimension information may be, for example, 300X700, KL1(3)300X700, or KL1(400X800), so that the beam height and the beam width of the beam member can be identified by identifying the cross-section dimension information.
For example, assuming that the cross-sectional dimension information is 300 × 700, it can be determined that the beam width is 300 and the beam height is 700 by identifying the cross-sectional dimension information 300 × 700.
In addition, it should be noted that, the beam width in the present application may be identified and determined according to the section dimension information, and may also be identified according to the distance between the parallel beam lines, and when there is a difference between the beam width identified by the distance between the parallel beam lines and the beam width identified by the section dimension information, a collation prompt message may also be output to prompt the user to perform collation.
It should be noted that, in the present application, besides the plan view in the drawing, the professional form, the elevation view, the cross-section thumbnail, and the like in the drawing can be identified.
And 102, classifying the pixels according to the layer names or the graphic attributes of the pixels corresponding to the pixels to obtain a plurality of types of graph groups corresponding to each plane graph.
In this embodiment, pixels belonging to the same class in the plane map may be classified according to a graphic attribute of the pixel or a layer name corresponding to the pixel to obtain a multi-class group. The multi-class graph groups at least comprise a plane graph name graph group, an axis name graph group and various component graph groups. The plane diagram name group may be a group corresponding to a plane diagram name of a plane diagram, the axis may be a group corresponding to an axis in a plane diagram, the axis name may be a group corresponding to an axis name in a plane diagram, and each component diagram group may be a group diagram composed of various component pixels.
In this embodiment, the method for classifying pixels belonging to the same class in a plane graph according to layer names corresponding to the pixels may include: and classifying the pixels according to the layer names corresponding to the pixels and the content of the pixels.
For example, fig. 3 is a diagram illustrating a correspondence relationship between layer names, pixel contents, and pixel groups corresponding to pixels in a plane graph according to an embodiment of the present application. As shown in fig. 3, assuming that the plan view is a building-type plan view, when the layer name corresponding to a pixel is C-AXIC-NUM and the content of the pixel is a number label (for example, r, C, or C), the pixel may be determined to be an axis name, and thus the pixel is classified into an axis name group.
103, dividing the drawing according to the plan name map group, the axis map group and the axis name map group to obtain each plan in the drawing; and determining the position of the positioning point of each plane graph according to the axis graph group and the axis name graph group.
In this step, the method for dividing the drawing according to the plan name map group, the axis map group, and the axis name map group to obtain each plan in the drawing may include:
determining a plane graph name and an axis endpoint corresponding to the plane graph as a boundary of the plane graph, and dividing the plane graph according to the boundary of the plane graph; or, the plan name and the axis name corresponding to the plan are determined as the boundary of the plan, and the plan is divided according to the boundary of the plan.
Specifically, fig. 4 is a schematic structural diagram of a plan view obtained on the basis of the structure shown in fig. 2 according to an embodiment of the present application, as shown in fig. 4, an axis in the plan view 1 in the embodiment of the present application spans (for example, crosses or longitudinally spans) the plan view, and a length of the axis is greater than a length of the plan view 1 in a direction in which the axis extends. For example, the length across axis A of plan view 1 is greater than the length of plan view 1 in the transverse direction, and the length across axis 5 of plan view 1 is greater than the length of plan view 1 in the longitudinal direction. It can be seen that the end points of the axes are located outside the plan view, and it should be noted that the axis names are located at the end points of the axes, so that the end points and the axis names of the axes are located outside the plan view 1, and the boundaries of the plan view 1 can be defined.
And the plan view name in the embodiment of the application is also positioned at the periphery of the plan view, and the boundary of the plan view can be defined, so that the boundary of the plan view can be defined according to the plan view name, the axis endpoint and the axis name, and the plan view can be divided according to the boundary of the plan view.
Referring to fig. 4, it can be understood that the boundaries of the plan view 1 can be defined according to the plan view name and the axis line end points in the plan view 1, or according to the plan view name and the axis line name, so as to demarcate the plan view 1. Similarly, the boundaries of the plan view 2 may be defined according to the plan view name and the axis line end points in the plan view 2, or according to the plan view name and the axis line name, so as to demarcate the plan view 2.
Further, in this embodiment of the present application, the method for determining the location of the anchor point of each plane map according to the axis map group and the axis name map group may include:
two intersecting axes are selected from the axes of the plan view, and the intersection of the two axes is located in the plan view, and the intersection of the two axes is determined as the location point position.
For example, referring to FIG. 4, the intersection of axis C and axis 1 may be selected as the location of the anchor point in the plan view of FIG. 1.
It should be noted that, in the embodiment of the present application, the distribution and names of the axes corresponding to different plan views are the same, for example, the distribution and names of the axes corresponding to each plan view may be the distribution and names of the axes corresponding to the plan view 1 in fig. 4.
In this step, when the positioning point position is determined for each plan view, the axis names of the two axes selected by the different plan views may be made the same. That is, for each plan view, the intersection of the axis C and the axis 1 is determined as the location point of the plan view. Therefore, when the single-layer models identified by different plane graphs are assembled to construct the three-dimensional model, the positioning point positions of each plane graph are overlapped in the vertical direction, so that each plane graph can be aligned up and down, and the construction accuracy of the three-dimensional model is improved.
And 104, determining the elevation of each plane, and determining the splicing insertion point of each plane in the three-dimensional model according to the plane name corresponding to each plane and the elevation of each plane.
In this step, the method for determining the assembly insertion point of each plan in the three-dimensional model according to the plan name corresponding to each plan and the elevation of each plan may include:
and 1041, determining the number of layers of the plan in the entity structure corresponding to the three-dimensional model and the standard layer sequence number corresponding to the plan according to the plan name corresponding to the plan.
It should be noted that, in the embodiment of the present application, the plan view name may specifically include: the number of layers of the plane graph in the solid structure corresponding to the three-dimensional model and the standard layer serial number corresponding to the plane graph.
For example, if the plan is a building plan, the plan name corresponding to the plan may specifically be: the floor of the building corresponding to the three-dimensional model of the plan map and the standard floor serial number corresponding to the plane floor.
Assume that the plan name can be: the standard layer 1 (the construction drawing of the beam-slab leveling method of the second underground layer), the standard layer 2 (the construction drawing of the beam-slab leveling method of the first underground layer), the standard layer 3 (the construction drawing of the beam leveling method of the first underground layer), the standard layer 4 (the construction drawing of the beam leveling method of the second underground layer), the standard layer 5 (the construction drawing of the beam leveling method of the third underground layer), the standard layer 6 (the construction drawing of the beam leveling method of the fourth standard layer), the standard layer 7 (the construction drawing of the beam leveling method of the fifth standard layer), the standard layer 8 (the construction drawing of the beam leveling method of the sixth to the eleventh standard layer), the standard layer 9 (the construction drawing of the beam leveling method of the twelfth to the sixteenth standard layer), the standard layer 10 (the construction drawing of the seventeenth beam leveling method), the standard layer 11 (the construction drawing of the beam leveling method of the eighteenth to the twenty layers), and the standard layer 12 (the construction drawing of the roof beam leveling method).
It should be noted that, when the plan name corresponding to a certain plan is the 1 st standard floor (the underground second floor beam-slab leveling construction drawing), it can be determined according to the plan name that the floor where the plan is located in the building corresponding to the three-dimensional model is the underground second floor, and the standard floor number corresponding to the plan is 1. And when the plan view name corresponding to a certain plan view is the 9 th standard floor (twelve-sixteen floor beam leveling construction drawing), the floor where the plane floor is located in the building corresponding to the three-dimensional model is the twelfth-sixteenth floor, and the standard floor number is 9, that is, the structural plan views of the twelfth-sixteenth floor in the building corresponding to the three-dimensional model are the plan views.
Step 1042, sorting the plane maps in the drawing according to the number of layers of the plane maps in the entity structure corresponding to the three-dimensional model and the standard layer number corresponding to the plane maps to determine a first layer plane map located at a first layer of the three-dimensional model, a second layer plane map located at a second layer of the three-dimensional model, a third layer plane map located at a third layer of the three-dimensional model, and an nth layer plane layer located at an nth layer of the three-dimensional model in the plane maps; wherein n is a positive integer.
In this step, it is assumed that the drawing includes twelve plane views, where the plane views of the twelve plane views have the following names: the standard layer 1 (the construction drawing of the beam-slab leveling method of the second underground layer), the standard layer 2 (the construction drawing of the beam-slab leveling method of the first underground layer), the standard layer 3 (the construction drawing of the beam leveling method of the first underground layer), the standard layer 4 (the construction drawing of the beam leveling method of the second underground layer), the standard layer 5 (the construction drawing of the beam leveling method of the third underground layer), the standard layer 6 (the construction drawing of the beam leveling method of the fourth standard layer), the standard layer 7 (the construction drawing of the beam leveling method of the fifth standard layer), the standard layer 8 (the construction drawing of the beam leveling method of the sixth to the eleventh standard layer), the standard layer 9 (the construction drawing of the beam leveling method of the twelfth to the sixteenth standard layer), the standard layer 10 (the construction drawing of the seventeenth beam leveling method), the standard layer 11 (the construction drawing of the beam leveling method of the eighteenth to the twenty layers), and the standard layer 12 (the construction drawing of the roof beam leveling method).
Then, according to the plan view names of the twelve plan views, a plan view with a plan view name of "1 st standard floor (two-floor beam slab leveling construction drawing)" may be determined as a first floor plan view located at a first floor of the three-dimensional model, a plan view with a plan view name of "2 nd standard floor (one-floor beam slab leveling construction drawing)" may be determined as a second floor plan view located at a second floor of the three-dimensional model, a plan view with a plan view name of "3 rd standard floor (one-floor beam slab leveling construction drawing)" may be determined as a third floor plan view located at a third floor of the three-dimensional model, and plan views with "8 th standard floor (six to ten-floor beam leveling construction drawings)" may be determined as an eighth floor plan view, a ninth floor plan view, a tenth floor plan view, a twelfth floor plan view, a third floor plan view, a fourth floor view, a third floor view, a fourth floor view, a third floor view, a fourth floor view, a third floor view, And a thirteenth floor plan, a.
And 1043, determining the assembling insertion point of the first-layer plane graph in the three-dimensional model according to the elevation corresponding to the first-layer plane graph, determining the assembling insertion point of the second-layer plane graph in the three-dimensional model according to the elevation corresponding to the second-layer plane graph, and so on, and determining the assembling insertion point corresponding to each plane graph.
Note that the elevation means a height of the base of the floor corresponding to each plan view with respect to the ground. And the elevation of each plane can be recorded in a floor table or a vertical section elevation table, the floor table or the vertical section elevation table can be positioned at the periphery of the plane, and the elevation of each plane can be determined by identifying the number of the floor table or the vertical section elevation table corresponding to each plane at the column of the elevation of the floor level where each plane is positioned in the solid structure corresponding to the three-dimensional model.
For example, fig. 5 is a schematic structural diagram of a floor surface according to an embodiment of the present application, and as shown in fig. 5, a first floor plan (i.e., a beam-slab plane construction drawing of a second floor) has an elevation of-8.8 meters (m) and a floor height of 3.5 m. The elevation of the second floor plan (i.e. the one-floor beam-slab construction plan) is-8.8 + 3.5-5.3 m, and the floor height is 5.25 m. Therefore, the elevation corresponding to each floor plan can be determined by identifying the floor table.
And then, determining elevations corresponding to the plane diagrams of the layers as assembly insertion points of the plane diagrams of the layers in the three-dimensional model. That is, the elevation corresponding to the first-layer plan is determined as the splicing insertion point corresponding to the first-layer plan, the elevation corresponding to the second-layer plan is determined as the splicing insertion point corresponding to the second-layer plan, and so on, to determine the splicing insertion point corresponding to each plan.
And 105, assembling the single-layer model identified by each plane graph according to the multi-class graph groups, the positioning point positions and the assembling insertion points to establish a three-dimensional model.
It should be noted that, in the embodiment of the present application, the graph group includes, in addition to the above-mentioned plane view name graph group, axis line graph group, and axis line name graph group, also includes: various component diagram groups and labeled information diagram groups.
The component drawing group specifically comprises a wall drawing group, a filler wall drawing group, a beam drawing group, a column drawing group, a door drawing group, a window drawing group, a stair drawing group, a floor slab opening drawing group and the like.
And, the label information graph group may be a graph group corresponding to label information for a component in the component graph group. The labeled information graph group may specifically include: wall plan drawing set, beam marking drawing set, column marking drawing set, door marking drawing set, window marking drawing set, and the like.
And in this step, mainly assemble the single-layer model generated by identifying each plane graph by identifying the multi-class graph groups, the positioning point positions and the assembling insertion points to jointly establish a three-dimensional model, and the specific method comprises the following steps:
and 1051, inserting each plane graph into the corresponding splicing insertion points, and enabling the positioning point positions in each plane graph to be overlapped in the vertical direction to form a three-dimensional model frame.
Step 1052, determining three-dimensional model components and three-dimensional model data according to the component graph group and the marking information graph group corresponding to each plan.
It should be noted that, the marking information of the component in the embodiment of the present application may provide the component with size information that cannot be embodied in the drawing component group. For example, if the member is a beam member, the size information that the beam member can only represent in a plan view is: the length and width dimensions of the beam member cannot be represented, so that the height dimension of the beam member needs to be marked, and the height dimension of the beam member is the marking information of the beam member.
