Technical Field

[0002] In the field of architectural engineering design, two-dimensional plan drawings are the core technical documents for conveying structural design intentions, containing design information such as component layout, cross-sectional dimensions, and reinforcement parameters, while three-dimensional models are the basic carrier for realizing digital construction and management.

[0003] Currently, in related technologies, the process of transferring design information from two-dimensional planar drawings to three-dimensional models usually relies on manual input. Designers need to first identify the graphic elements in the two-dimensional planar drawings, extract the design information, and then locate the corresponding three-dimensional components in the three-dimensional modeling software and manually input and fill in the design information. However, this method takes a long time, resulting in low efficiency in filling the design information in the three-dimensional model.

[0039] Alternatively, as an alternative implementation method, such as Figure 2 As shown, the method for filling in the design information of a 3D model can be performed by an electronic device, such as... Figure 1 The user equipment or server shown includes the following specific steps:

[0040] S202, Based on at least one graphic element contained in the two-dimensional flat diagram, generate at least one first component, wherein the first component is a three-dimensional component;

[0041] Optionally, in this embodiment, the two-dimensional planar drawing may be, but is not limited to, an engineering design drawing drawn using a planar overall representation method, which presents the arrangement, geometric dimensions, numbering, and related design annotations of components such as beams, columns, and walls in the building structure in a two-dimensional vector form.

[0042] Optionally, in this embodiment, graphic elements can be, but are not limited to, the basic units constituting component design information in a two-dimensional planar drawing. These include graphic elements reflecting the component's geometry, such as the axis of a beam or the outline of a column, as well as text elements describing component attributes, such as component number, cross-sectional dimension annotations, and material specifications. Each graphic element corresponds to one or more design information items for the component and is the smallest unit for splitting and extracting two-dimensional design information.

[0043] Optionally, in this embodiment, the first component can be, but is not limited to, a three-dimensional solid component generated based on a single or a group of related graphic elements in a two-dimensional planar drawing, according to preset three-dimensional modeling rules, such as determining the cross-sectional shape of the three-dimensional component based on the cross-sectional dimensions of the graphic element, determining the length of the three-dimensional component based on the axis length, and determining the modeling logic based on the component type. For further example, assuming there is a graphic element "KL1 (500×800)," if the beam axis length in the graphic element is 6m, according to the three-dimensional modeling rules for frame beams, a three-dimensional rectangular beam entity with a length of 6m and a cross-sectional dimension of 500mm×800mm can be generated. This entity can be understood as the first component corresponding to the graphic element "KL1".

[0044] Optionally, in this embodiment, by using a two-dimensional flat drawing as the data source, firstly, graphic elements and text elements related to the component in the drawing are extracted as graphic elements through graphic element recognition, and then each graphic element is transformed into a three-dimensional entity with corresponding geometric parameters according to the three-dimensional modeling rules corresponding to the component type, so as to obtain at least one first component, thereby realizing the transformation of two-dimensional design information into three-dimensional form.

[0045] S204, if at least one of the first components has a first target component that is successfully matched with the three-dimensional model, establish the association relationship between the first graphic element corresponding to the first target component and the three-dimensional model;

[0046] Optionally, in this embodiment, the three-dimensional model may be, but is not limited to, a digital model constructed using three-dimensional modeling software that reflects the spatial form and basic attributes of the engineering entity, and may include, but is not limited to, information such as the geometric shape and spatial position of the three-dimensional components.

[0047] Optionally, in this embodiment, the association relationship may be, but is not limited to, a one-to-one correspondence between the first graphic element corresponding to the first target component and the matched three-dimensional component in the three-dimensional model after the first target component is successfully matched with the three-dimensional model. It may be, but is not limited to, stored in the form of data mapping, such as recording the correspondence between graphic element ID and three-dimensional component ID, so as to ensure that the two-dimensional design information can accurately point to the corresponding three-dimensional component.

[0048] Optionally, in this embodiment, all generated first components are matched with the three-dimensional components in the existing three-dimensional model. The matching logic may include, but is not limited to, spatial position overlap calculation, cross-sectional size comparison, and component type consistency verification, thereby filtering out the first components that meet the matching conditions. Then, the first target component is used as an intermediate component, and its corresponding first graphic element is bound to the matched three-dimensional component in the three-dimensional model to form a direct correspondence between the first graphic element and the three-dimensional component, and the association relationship is stored in the form of data records.

[0049] Optionally, in this embodiment, the spatial overlap calculation is the core logic for determining whether two components (such as the axis of a beam) in a two-dimensional plan drawing and components in a three-dimensional model (such as the positioning lines of a Revit beam) are the same component by quantifying the overlap ratio in the horizontal or spatial coordinate system. Specifically, the horizontal two-dimensional coordinate range of the two-dimensional graphic elements (such as the X and Y coordinates of the start and end points of the axis) and the spatial position parameters of the three-dimensional component (such as the projection range of the axis in the horizontal two-dimensional coordinate system) are extracted, and the proportion of the length of the overlapping part to the total length is calculated. For example, the axis range of beam KL1 in the two-dimensional plan drawing is X=10m~16m, Y=8m, and the projection range of the axis of beam L-01 in the three-dimensional model is X=10.1m~15.9m, Y=8m. The overlap length is 5.8m, and the total length is 6m, with an overlap of 96.7%, which can be determined as a positional match.

[0050] Optionally, in this embodiment, the cross-sectional dimension comparison is performed by comparing the cross-sectional parameters (such as width × height) of the components labeled in the two-dimensional plan drawing with the cross-sectional attributes of the components in the three-dimensional model to verify whether the two match. Specifically, the cross-sectional labels in the two-dimensional drawing (such as "500×800" indicating a width of 500mm and a height of 800mm) are extracted and compared with the cross-sectional dimension parameters of the three-dimensional components (such as "b=500mm, h=800mm" for a Revit beam) for numerical error analysis, which can be, but is not limited to, deviations within a certain range. For example, if the KL2 beam is labeled "400×700" in the two-dimensional plan drawing, the corresponding beam cross-section in the three-dimensional model is "405×695", with errors of 1.25% and 0.71% respectively, both within the allowable range, and is judged to be a cross-sectional match.

[0051] Optionally, in this embodiment, the component type consistency check is performed by verifying whether the type identifier of the component in the two-dimensional plan drawing is consistent with the type attribute of the component in the three-dimensional model, ensuring that they belong to the same type of structural component. Specifically, the numbering information of the two-dimensional graphic elements (e.g., "KL" represents a frame beam, "KZ" represents a frame column, and "L" represents a non-frame beam) is parsed and compared with the type parameters of the three-dimensional component, requiring a complete match in type classification (e.g., "KL" must correspond to the "frame beam" type in the three-dimensional model). For example, the graphic element numbered "KZ1" in the two-dimensional drawing (representing a frame column) needs to match the component with the type attribute "frame column" in the three-dimensional model. If the corresponding three-dimensional component type is "structural column", it is determined that the types are inconsistent, and the match fails.

[0052] Optionally, in this embodiment, if a first target component in at least one of the first components successfully matches a three-dimensional model, an association relationship is established between the first graphic element corresponding to the first target component and the three-dimensional model. This can also be understood, but is not limited to, as establishing an association relationship between the first target component and a three-dimensional component in the three-dimensional model if a first target component in at least one of the first components successfully matches a three-dimensional component in the three-dimensional model.

[0053] Optionally, in this embodiment, if at least one of the first components fails to match the first target component with the three-dimensional model, the geometric features of the first component can be matched with the geometric features of the three-dimensional components in the three-dimensional model. This allows the matching to continue even if the original matching fails, ensuring that the first component can be associated with the three-dimensional model.

[0054] S206, based on the association relationship, fill the design information contained in the first graphic element into the three-dimensional model, wherein the design information is used to indicate the functional attributes and engineering parameters of the three-dimensional components contained in the three-dimensional model.

[0055] Optionally, in this embodiment, the design information may be, but is not limited to, information contained in the two-dimensional planar drawing elements that defines the functions and engineering application parameters of the three-dimensional components. It may be, but is not limited to, functional attributes such as component type, purpose, and stress level, and engineering parameters such as cross-sectional dimensions, material strength, reinforcement parameters, and construction process requirements. The design information may include, but is not limited to, design element information, outer contour information, and standard design data information.

[0056] Optionally, in this embodiment, based on the established association between the first graphic element and the three-dimensional component, complete design information is first extracted from the first graphic element, and then the extracted design information is entered into the associated three-dimensional component attributes one by one according to the information storage format of the three-dimensional model, such as the attribute parameter bar of the Revit component, thus completing the transfer and filling of design information from the two-dimensional graphic element to the three-dimensional model.

[0057] It should be noted that, without importing design information, the 3D model of a component obtained through 3D modeling software usually lacks some detailed design information, such as reinforcement parameters and concrete strength grade. However, the technical solution described in this application embodiment can establish an association between the first graphic element corresponding to the first target component and the 3D component in the 3D model after the first target component and the 3D component in the 3D model are successfully matched. Then, based on the association, the design information contained in the first graphic element is filled into the 3D component. This enables the design information contained in the 2D flat drawing to be quickly filled into the 3D model, improving the efficiency of filling the 3D model with design information.

[0058] It is understood that, through the embodiments provided in this application, there is no need for manual comparison one by one. By automatically establishing the matching and association relationship between the first component and the three-dimensional model, the manual matching cost of two-dimensional graphic elements and three-dimensional components is reduced, and the association efficiency is improved. Based on the established association relationship, design information can be automatically filled from the first graphic element to the three-dimensional model, avoiding repetitive manual input operations and significantly improving the filling efficiency of design information. The establishment of the association relationship ensures the accuracy of design information transmission, reduces errors in the manual matching and input process, realizes the efficient and accurate transmission of two-dimensional planar drawing design information to the three-dimensional model, and solves the problem of low design information filling efficiency in the prior art.

[0059] Through the embodiments provided in this application, at least one first component is generated based on at least one graphic element contained in a two-dimensional flat drawing, wherein the first component is a three-dimensional component; when a first target component in at least one of the first components successfully matches a three-dimensional model, an association relationship is established between the first graphic element corresponding to the first target component and the three-dimensional model; based on the association relationship, the design information contained in the first graphic element is filled into the three-dimensional model, wherein the design information is used to indicate the functional attributes and engineering parameters of the three-dimensional components contained in the three-dimensional model, thereby achieving the purpose of reducing the filling of design information in the three-dimensional model, thereby achieving the technical effect of improving the filling efficiency of design information in the three-dimensional model, and thus solving the technical problem of low filling efficiency of design information in the three-dimensional model.

[0060] As an optional approach, before establishing the association between the first graphic element corresponding to the first target component and the 3D model, the method further includes:

[0061] S1-1, Establish a horizontal two-dimensional coordinate system based on the two-dimensional flat surface diagram;

[0062] Iterate through all first components and perform the following steps on the current component:

[0063] S1-2, Obtain the height information corresponding to the current component;

[0064] S1-3, obtain the midpoint coordinates of the current component, where the midpoint coordinates are used to indicate the geometric center of the current component in the horizontal two-dimensional coordinate system;

[0065] S1-4. Based on the midpoint coordinates and the height information corresponding to the current component, perform fuzzy matching on the 3D model to obtain at least one second component, wherein the second component matches the midpoint coordinates and height information.

[0066] Optionally, in this embodiment, the horizontal two-dimensional coordinate system may be, but is not limited to, a two-dimensional rectangular coordinate system established based on the planar space of the two-dimensional flat drawing. It may be, but is not limited to, using a fixed reference point in the two-dimensional flat drawing, such as the origin of the grid or the lower left corner of the drawing, as the origin of the coordinate system, with the horizontal direction in the drawing as the X-axis and the vertical direction as the Y-axis. This system is used to quantify the planar spatial position of the graphic elements in the two-dimensional flat drawing and the corresponding first component, thereby providing a unified planar coordinate reference for matching the spatial position of the first component with the three-dimensional model, avoiding position judgment deviations caused by inconsistent coordinate systems, and ensuring spatial consistency of the matching.

[0067] Optionally, in this embodiment, the height information may be, but is not limited to, the vertical position parameter of the current component. It can also be understood as the position parameter of the current component on a two-dimensional coordinate system perpendicular to the horizontal. In the building model, it can correspond to the height of a building floor, used to reflect the vertical position of the component in three-dimensional space. Its function is to supplement the three-dimensional position information of the component and avoid misjudging components with different heights on the same plane due to matching only the planar position.

[0068] Optionally, in this embodiment, the midpoint coordinates may be, but are not limited to, the geometric center coordinates of the current component's planar projection in the horizontal two-dimensional coordinate system. They are obtained by calculating the X and Y axis coordinates of the center point of the component's planar projection and are used to accurately indicate the planar center position of the component. This simplifies the planar position matching logic and improves matching efficiency.

[0069] Optionally, in this embodiment, the second component may be, but is not limited to, a three-dimensional component that meets the conditions after preliminary matching of the three-dimensional model based on the midpoint coordinates and height information. This can narrow down the range of subsequent precise matching, reduce the amount of calculation, and improve the overall matching efficiency.

[0070] Optionally, in this embodiment, based on the two-dimensional planar drawing, an origin and coordinate axes are selected to construct a unified planar coordinate system; then, all first components are accessed sequentially, each accessed first component is determined as the current component, and the vertical position parameters of the current component are extracted as height information; then, the planar projection shape of the current component in the horizontal two-dimensional coordinate system is determined, and the X and Y coordinates of the projection center are obtained through geometric calculation as the midpoint coordinates to reflect the planar center position of the component; finally, using the midpoint coordinates and height information as dual conditions, components are screened in the three-dimensional model. On the plane, the distance between the three-dimensional component and the midpoint coordinates meets the distance condition; vertically, the height meets a specific height condition, such as being on the second floor, and the three-dimensional components that meet the conditions are then determined as the second components.

[0071] Optionally, in this embodiment, fuzzy matching can be, but is not limited to, a technical logic for preliminary screening of candidate components by extracting the component's attribute features (such as midpoint coordinates, cross-sectional dimensions, component type, etc.) from the two-dimensional planar drawing components and the three-dimensional model components, and setting reasonable error thresholds (such as spatial position overlap greater than or equal to the overlap threshold, and cross-sectional dimension error less than or equal to the error threshold). For example, several second components can be screened from the three-dimensional model based on the midpoint coordinates and height information of the two-dimensional beam, and then the range can be further narrowed down by conditions such as projection line distance and axis overlap, thereby reducing the computational load of subsequent precise matching, while being compatible with minor deviations in the design or modeling process, and improving the efficiency and robustness of matching.

[0072] To further illustrate the fuzzy matching process, consider three different beams, A, B, and C, in a 3D model. Obtain the midpoints of the projections of beams A, B, and C onto a horizontal 2D coordinate system. The midpoint coordinates of beam A are (2560mm, 3280mm), the midpoint coordinates of beam B are (2320mm, 5750mm), and the midpoint coordinates of beam C are (2680mm, 3350mm). Cache the beam coordinates of beams A, B, and C.

[0073] Next, following the 500mm rounding rule, group the X and Y coordinates in 500mm intervals, take the nearest 500mm integer multiples, calculate the rounded X and Y values ​​for each beam, and construct a Key in the format (X, Y, 0).

[0074] It should be noted that in the rounding rule, if the remainder when the coordinate value is divided by 500 is less than or equal to 250, it is rounded down; if the remainder is greater than 250, it is rounded up. Therefore, in calculating the Key of beam A, since X = 2560mm and 2560 ÷ 500 ≈ 5.12, it is rounded to 5 × 500 = 2500mm. Y = 3280mm and 3280 ÷ 500 ≈ 6.56, it is rounded to 7 × 500 = 3500mm. The final Key of beam A is (2500, 3500, 0). Similarly, the Key of beam B is (2500, 6000, 0), and the Key of beam C is (2500, 3500, 0).

[0075] Furthermore, the beams are grouped according to the constructed key, and IDs with the same key are grouped together to form cached data. For example, beams A and C are in one group, and beam B is in another group.

[0076] Then, extract the midpoint coordinates of the two-dimensional beam (equivalent to the current component) generated from the elements of the two-dimensional flat drawing to be matched, such as (2520mm, 3310mm), and calculate the fuzzy key according to the same rounding rule to obtain the fuzzy key as (2500, 3500, 0).

[0077] Finally, since the fuzzy key of the two-dimensional beam is the same as the key of beam A and beam C, beam A and beam C are identified as the second components that match the midpoint coordinates and height information of the two-dimensional beam.

[0078] It should be noted that by first establishing a unified coordinate system and then extracting the height information and midpoint coordinates of each first component, a small number of second components are selected from a large number of three-dimensional components based on two parameters. This not only avoids misjudgment of components with different heights on the same plane, but also enables the rapid acquisition of second components that match the current component, thus improving the efficiency of obtaining second components by matching the current component.

[0079] The embodiments provided in this application establish a horizontal two-dimensional coordinate system based on a two-dimensional planar diagram; traverse all first components and perform the following steps on the current component: obtain the height information corresponding to the current component; obtain the midpoint coordinates corresponding to the current component, wherein the midpoint coordinates are used to indicate the geometric center of the current component in the horizontal two-dimensional coordinate system; based on the midpoint coordinates and the height information corresponding to the current component, perform fuzzy matching on the three-dimensional model to obtain at least one second component, wherein the second component matches the midpoint coordinates and height information. By first establishing a unified coordinate system and then extracting the height information and midpoint coordinates of each first component, a small number of second components are selected from a large number of three-dimensional components based on two parameters. This avoids misjudgment of components with different heights on the same plane and enables rapid acquisition of second components that match the current component, thus improving the efficiency of obtaining second components through matching the current component.

[0080] As an optional approach, after obtaining at least one second component by performing fuzzy matching on the 3D model based on the midpoint coordinates and the height information corresponding to the current component, the method further includes:

[0081] S2-1, Obtain the projection line of each second component in the horizontal two-dimensional coordinate system;

[0082] S2-2, If the distance between the projection line of the third component and the midpoint coordinates in at least one second component is less than the width of the third component, obtain the axis corresponding to the current component and obtain the axis corresponding to the third component, wherein the axis is located in the horizontal two-dimensional coordinate system;

[0083] S2-3, Obtain the overlap condition, and if the overlap condition is satisfied between the axis corresponding to the current component and the axis corresponding to the third component, determine the current component as the first target component;

[0084] S2-4, Establish the association between the first target component and the third component.

[0085] Optionally, in this embodiment, the projection line of the second component may refer to, but is not limited to, the line segment formed after the second component in the three-dimensional model is projected onto the horizontal two-dimensional coordinate system in a direction perpendicular to the plane of the horizontal two-dimensional coordinate system, which can reflect the planar outline or axis position of the second component, thereby enabling the planar shape of the three-dimensional second component to be transformed into a two-dimensional line segment.

[0086] Optionally, in this embodiment, the third component may be, but is not limited to, a three-dimensional component selected from at least one second component that satisfies the condition that the distance between the projection line and the midpoint coordinate of the current component is less than or equal to its own width. It can further narrow down the range based on the second components obtained by fuzzy matching, and select components that are more related to the planar position of the current component, thereby reducing the amount of calculation.

[0087] Optionally, in this embodiment, the axis of the current component may, but is not limited to, refer to the central axis of the current component in the horizontal two-dimensional coordinate system. It is usually the core line segment that reflects the length direction of the component. Its position and direction are consistent with the axis of the corresponding component in the two-dimensional planar drawing. It can serve as a geometric reference for matching the current component with the third component. It can, but is not limited to, determine whether the two are corresponding components by judging the overlap condition with the axis of the third component.

[0088] Optionally, in this embodiment, the axis of the third component may, but is not limited to, refer to the central axis of the third component in the horizontal two-dimensional coordinate system, and may, but is not limited to, be consistent with the position of the projection line of the third component, reflecting the length direction and planar position of the third component, and can be used as a comparison benchmark for overlapping and matching with the axis of the current component. By judging the overlap condition of the two axes, it can be determined whether the two are corresponding components.

[0089] Optionally, in this embodiment, each second component in the three-dimensional model is projected onto the horizontal two-dimensional coordinate system along a direction perpendicular to the horizontal two-dimensional coordinate system to generate a projection line that reflects the planar outline or axial position of the second component. The geometric parameters (such as length and endpoint coordinates) of the projection line are consistent with the shape of the second component in the horizontal direction, thereby converting the three-dimensional second component into a two-dimensional projection line and eliminating the dimensional difference between three-dimensional and two-dimensional.

[0090] Next, calculate the vertical distance between the projection line of each second component and the midpoint coordinates of the current component, and select the second components whose distance is less than their own width as the third components; then extract the central axes of the current component and the third component in the horizontal two-dimensional coordinate system respectively.

[0091] Then, the preset overlap conditions are invoked to calculate whether the axis of the current component and the axis of the third component meet the preset overlap conditions. This can be achieved, but is not limited to, by dividing the length of the overlapping line by the shorter axis length to obtain the overlap ratio. If the ratio is greater than or equal to the threshold corresponding to the overlap condition, the current component is determined to be the first target component corresponding to the third component. By quantifying the overlap conditions, the axial correlation between the current component and the third component is accurately determined, avoiding misjudgments caused by slight positional deviations and ensuring the accurate correspondence between the first target component and the third component.

[0092] Finally, after determining the first target component, a one-to-one correspondence between the two is established in the form of data mapping.

[0093] Understandably, by filtering the midpoint distance of the projection line and verifying the overlap of the axis, the range of candidate components is further narrowed, thereby improving the positioning accuracy of the first target component; and by judging the axis correlation based on the quantified overlap condition, the subjective error of manual judgment is avoided, and the matching accuracy between the first target component and the third component is improved.

[0094] The embodiments provided in this application obtain the projection lines corresponding to each second component in a horizontal two-dimensional coordinate system. If, in at least one second component, the distance between the projection line corresponding to the third component and its midpoint coordinate is less than the width of the third component, the axis corresponding to the current component and the axis corresponding to the third component are obtained, wherein the axes are located in a horizontal two-dimensional coordinate system. Overlap conditions are obtained, and if the overlap conditions are met between the axis corresponding to the current component and the axis corresponding to the third component, the current component is determined as the first target component. An association relationship is established between the first target component and the third component. By using projection line midpoint distance filtering and axis overlap matching for dual verification, the range of candidate components is further narrowed, thereby improving the positioning accuracy of the first target component. Furthermore, the axis correlation is judged based on quantified overlap conditions, avoiding subjective errors from manual judgment and improving the matching accuracy between the first target component and the third component.

[0095] As an optional approach, the overlap condition is obtained, including at least one of the following:

[0096] S3-1, Obtain the component type corresponding to the current component, and obtain the overlap condition based on the component type;

[0097] S3-2, obtain the deviation information of the two-dimensional flat drawing, and obtain the overlap condition based on the deviation information. The deviation information is used to indicate the drawing accuracy of the two-dimensional flat drawing.

[0098] Optionally, in this embodiment, the component type corresponding to the current component may refer to, but is not limited to, standard structural component types such as beam, column, slab, wall, and foundation, which are based on the structural category to which the current component belongs. These types are core components in building structural design, and their geometric shapes, stress characteristics, and modeling rules are significantly different.

[0099] Optionally, in this embodiment, the deviation information of the two-dimensional flat drawing may be, but is not limited to, quantitative data used to indicate the accuracy of the two-dimensional flat drawing. It may include, but is not limited to, the deviation value of the intersection of the beam axis and the grid, the distance from the component annotation center point to the component line, and the completeness of the geometric parameters of complex components such as curved beams. This information can reflect the degree of deviation between the two-dimensional flat drawing and the ideal design state, thereby providing a basis for the dynamic adjustment of the overlap condition. For example, if a two-dimensional flat drawing with high accuracy is drawn, the corresponding overlap condition can be set higher to ensure accurate matching; while if a flat drawing with low accuracy is drawn, the corresponding overlap condition needs to be appropriately reduced to avoid matching failure due to drawing deviation.

[0100] To further illustrate, if the deviation between the beam axis and the grid in the two-dimensional flat drawing is less than or equal to 3mm and the annotation distance is less than or equal to 5mm, then the drawing accuracy of the two-dimensional flat drawing is high, and the overlap condition can be set to 85%. If the axis deviation is greater than 8mm and the annotation distance is greater than 12mm, then the drawing accuracy of the two-dimensional flat drawing is low, and the overlap condition can be set to 70%.

[0101] Optionally, in this embodiment, the component type of the current component is first determined by identifying the element attributes of the two-dimensional planar graph corresponding to the current component; then, based on the preset mapping relationship between component types and overlap conditions, the overlap condition threshold for the corresponding type is retrieved. By setting overlap conditions differently for component types, the problem of inaccurate matching of high-precision components or failure to match low-precision components caused by using a uniform threshold is avoided, ensuring that the overlap conditions are adapted to the component characteristics and that the overlap conditions match the component type, thereby improving the matching accuracy.

[0102] Optionally, in this embodiment, deviation information of the two-dimensional planar drawing is extracted through graphic element recognition, such as beam axis deviation, annotation distance, and completeness of complex component parameters. Then, the drawing accuracy level of the planar drawing is determined based on the deviation information. According to the preset mapping relationship between accuracy level and overlap conditions, the corresponding overlap condition threshold is obtained. By dynamically adjusting the overlap conditions based on the drawing accuracy of the two-dimensional planar drawing, the matching and adaptation problem caused by differences in drawing quality is solved. High-precision drawings correspond to high overlap conditions, thus ensuring accurate matching, while low-precision drawings correspond to low overlap conditions, improving the matching success rate when matching on low-precision drawings.

[0103] Optionally, in this embodiment, if two different overlap conditions are obtained at the same time, the overlap degree corresponding to the two different overlap degrees can be weighted and summed, and the overlap degree after weighted summation can be used as the new overlap condition.

[0104] Optionally, in this embodiment, different weights can be obtained according to the current project stage. For example, if fast matching is required in the preliminary modeling stage, the weight of drawing accuracy can be increased, such as a component type weight of 0.4 and a drawing accuracy weight of 0.6, to accommodate deviations in low-precision drawings. In the construction drawing refinement stage, high-precision matching is required, such as a component type weight of 0.7 and a drawing accuracy weight of 0.3, to ensure accurate matching of core components. This can meet the differentiated needs of different project stages, improve the adaptability of overlapping conditions and projects, and thus adapt to different requirements at different stages.

[0105] It should be noted that by using a dual approach—obtaining overlap conditions based on component type and obtaining overlap conditions based on deviation information from two-dimensional planar drawings—the problem of poor adaptability caused by using a uniform overlap threshold in existing technologies is solved. Different component types and different drawing accuracies correspond to differentiated overlap conditions, making the overlap conditions highly adaptable to the actual matching scenario. Moreover, there is no need to manually set overlap conditions; the acquisition is automated through component type recognition and deviation information extraction, reducing manual intervention costs and improving the efficiency of overlap condition acquisition.

[0106] The embodiments provided in this application obtain the component type corresponding to the current component and, based on the component type, obtain the overlap condition; they also obtain the deviation information of the two-dimensional flat drawing and, based on the deviation information, obtain the overlap condition, wherein the deviation information is used to indicate the drawing accuracy of the two-dimensional flat drawing. By using a dual approach of obtaining overlap conditions based on component type and based on the deviation information of the two-dimensional flat drawing, the poor adaptability problem caused by using a uniform overlap threshold in the prior art is solved. Different component types and different drawing accuracies correspond to differentiated overlap conditions, making the overlap conditions highly adaptable to the actual matching scenario; moreover, there is no need to manually set the overlap conditions, as the acquisition is automated through component type recognition and deviation information extraction, reducing manual intervention costs and improving the efficiency of obtaining overlap conditions.

[0107] As an optional approach, after establishing the association between the first graphic element corresponding to the first target component and the 3D model, the method further includes at least one of the following:

[0108] S4-1, In the case of multiple fourth components that fail to match in the 3D model, obtain the geometric features corresponding to the fourth components, and determine the second target component from at least one first component based on the geometric features corresponding to each fourth component; establish the association relationship between the second graphic element corresponding to the second target component and multiple fourth components;

[0109] S4-2, In the case that there are multiple fifth components that fail to match in at least one first component, obtain the geometric features corresponding to the fifth component, and determine the third target component from the three-dimensional model based on the geometric features corresponding to each fifth component; establish the association relationship between the third graphic element corresponding to the third target component and the multiple fifth components.

[0110] Optionally, in this embodiment, the fourth component may refer to, but is not limited to, a three-dimensional component that, after the initial matching process between the first target component and the three-dimensional model, has not been successfully matched with any first component, possesses a complete three-dimensional geometric shape (such as length, cross-section, and spatial position), but is not associated with the design information of the two-dimensional planar drawing.

[0111] Optionally, in this embodiment, geometric features may refer to, but are not limited to, the geometric parameters of the component in a horizontal two-dimensional coordinate system or three-dimensional space, and may include, but are not limited to, the component's midpoint coordinates, cross-sectional dimensions, length, axial direction, outer contour shape (such as arc or straight line), spatial position overlap, etc.

[0112] Optionally, in this embodiment, the second target component may refer to, but is not limited to, a first component selected from at least one first component whose geometric feature similarity to the merged fourth component meets a preset threshold, which can find a corresponding design information source for the merged fourth component, such as a second graphic element, to ensure that the fourth component to be merged can be associated with complete two-dimensional design information.

[0113] Optionally, in this embodiment, the fifth component may refer to, but is not limited to, multiple components in at least one first component that have not been successfully matched with any three-dimensional component. These components are associated with the design information of the two-dimensional planar drawing, but no corresponding three-dimensional model component has been found. For example, component E, generated based on the KL6 element of the planar drawing, does not find a corresponding Revit beam during the initial matching process, thus it is the fifth component; while in the three-dimensional model, there is a 12m long Revit beam L-11, which needs to be divided into 3 segments, each 4m long, and one of these segments matches component E.

[0114] Optionally, in this embodiment, the third target component may refer to, but is not limited to, a three-dimensional component that, after being selected and split from the three-dimensional model, has a geometric feature similarity to the fifth component that meets a preset threshold.

[0115] Optionally, in this embodiment, if there are multiple unmatched fourth components in the three-dimensional model, the geometric features of each fourth component are first extracted, and the merging conditions are determined by the geometric features. After merging, the merged geometric features are compared with all first components, and the first components with the same similarity are selected as the second target components. Finally, the association between the second graphic element corresponding to the second target component and the merged fourth component is established, and the design information is transmitted.

[0116] To further illustrate, optionally, if the second target component is determined from the first component based on the geometric characteristics of the fourth component, such as the splicing method, location, and connected components of the fourth component, and the fourth component is merged, and it is determined whether the merged component matches the second target component, if they match, then an association relationship is established between the fourth component and the second target component.

[0117] Optionally, in this embodiment, if there are multiple unmatched fifth components in the first component, the geometric features of each fifth component are extracted first; then, the separable third target components are selected from the three-dimensional model and split according to the geometric features of the fifth components; after splitting, the similarity of the geometric features of each split component with the fifth component is judged, and if the similarity is met, the association relationship between the third target component and the corresponding third graphic element of the fifth component is established.

[0118] It should be noted that by merging the first component that fails to match, or by breaking the three-dimensional components in the three-dimensional model that fails to match, matching can continue even when it fails. This allows for matching even in different complex projects, improving adaptability to complex projects and ensuring that two-dimensional design information can be fully transferred to the three-dimensional digital model.

[0119] It is understood that the content described in this embodiment can also be regarded as, in the case that the first target component in at least one first component fails to match with the three-dimensional model, matching is performed based on the geometric features of the first component and the geometric features of the three-dimensional component in the three-dimensional model, so that matching can continue even if the original matching fails, so as to ensure that the first component can be associated with the three-dimensional model.

[0120] Through the embodiments provided in this application, when there are multiple fourth components that fail to match in the 3D model, the geometric features corresponding to the fourth components are obtained, and a second target component is determined from at least one first component based on the geometric features corresponding to each fourth component; an association relationship is established between the second graphic element corresponding to the second target component and the multiple fourth components; when there are multiple fifth components that fail to match in at least one first component, the geometric features corresponding to the fifth components are obtained, and a third target component is determined from the 3D model based on the geometric features corresponding to each fifth component; an association relationship is established between the third graphic element corresponding to the third target component and the multiple fifth components.

[0121] By merging the first component that fails to match, or breaking the three-dimensional components in the three-dimensional model that fail to match, matching can continue even if it fails. This improves the adaptability to complex projects and ensures that two-dimensional design information can be fully transferred to the three-dimensional digital model.

[0122] As an optional approach, after filling the 3D model with the design information contained in the first graphic element based on the association relationship, the method also includes:

[0123] S5-1, Based on the correlation relationship, determine the fourth target component that matches the first graphic element from the three-dimensional model;

[0124] S5-2, Obtain the spatial information of the fourth target component, wherein the spatial information is used to indicate the position of the fourth target component in the three-dimensional model;

[0125] S5-3, based on the association relationship, fill the spatial information into the first graphic element.

[0126] Optionally, in this embodiment, the fourth target component may refer to, but is not limited to, the three-dimensional component determined from the three-dimensional model that corresponds to the first graphic element.

[0127] Optionally, in this embodiment, the spatial information may, but is not limited to, the positional parameters of the fourth target component in the three-dimensional model. It may include, but is not limited to, the coordinates of the fourth target component in the three-dimensional coordinate system, its spatial elevation, and its spatial relative position with surrounding components. This directly reflects the actual arrangement position of the fourth target component in the three-dimensional model, supplementing the two-dimensional first graphic element with three-dimensional spatial positional data. This solves the problem that the two-dimensional planar drawing only contains planar positional information and lacks three-dimensional spatial information, enabling the two-dimensional graphic element to possess both design attributes and three-dimensional spatial attributes. Furthermore, the spatial information may also include the component ID of the fourth target component.

[0128] Optionally, in this embodiment, by calling the mapping data between the first graphic element ID and the three-dimensional component ID stored in the association relationship, a three-dimensional component uniquely corresponding to the current first graphic element is determined from the three-dimensional model and used as the fourth target component.

[0129] Next, the three-dimensional spatial parameters of the fourth target component are extracted through the interface provided by the three-dimensional modeling software, including but not limited to three-dimensional coordinates, spatial elevation, relative position, component ID, etc.

[0130] Finally, the extracted spatial information is written into the first graphic element according to the preset format, so that the two-dimensional graphic element contains both design information and three-dimensional spatial information.

[0131] It should be noted that the existing relationships ensure the accuracy of spatial information transmission, while spatial information makes two-dimensional graphic elements more valuable for engineering guidance. This allows two-dimensional plan drawings to have both design information and spatial information from three-dimensional models, thus improving the comprehensiveness of information in two-dimensional plan drawings.

[0132] Through the embodiments provided in this application, a fourth target component matching the first graphic element is determined from the 3D model based on the association relationship; spatial information of the fourth target component is obtained, wherein the spatial information is used to indicate the position of the fourth target component in the 3D model; and the spatial information is filled into the first graphic element based on the association relationship. The existing association relationship ensures the accuracy of spatial information transmission, while the spatial information makes the 2D graphic element more valuable for engineering guidance, enabling the 2D plan drawing to possess both design information and spatial information from the 3D model, thus improving the comprehensiveness of the 2D plan drawing information.

[0133] As an optional approach, after filling the spatial information into the first graphic element based on the association relationship, the method also includes:

[0134] S6-1, Obtain the target design information of the first graphic element, wherein the target design information is used to indicate the modified design information;

[0135] S6-2, based on the correlation and spatial information, the target design information is determined as the design information corresponding to the fourth target component.

[0136] Optionally, in this embodiment, the target design information may refer to, but is not limited to, design change data initiated on the first element of the two-dimensional structural construction drawing, used to indicate the modified design information, and may include, but is not limited to, adjustments to component cross-sectional dimensions, changes in material strength, modifications to reinforcement parameters, and updates to component numbers.

[0137] Optionally, in this embodiment, the design change operation initiated by the user on the first graphic element is obtained through graphic element recognition in 2D design software, such as CAD, and extracted and converted into standardized modification information. This enables accurate acquisition of design change data from the 2D perspective, transforming unstructured modification operations into transferable quantitative information, providing a clear basis for subsequent synchronization to the 3D model, and avoiding errors in 3D model updates due to unclear modification information.

[0138] Next, based on the correlation, a fourth target component matching the first graphic element and located in the 3D model is identified. Then, a secondary verification is performed using the spatial information of the fourth target component to confirm the accuracy of the location. Finally, the acquired modification information is written into the attribute parameters of the fourth target component, updating its corresponding design information and synchronizing the 3D model with the 2D modifications. Through dual positioning using both correlation and spatial information, it ensures that modification information is accurately transmitted to the corresponding fourth target component in the 3D model, avoiding incorrect modification targets. Simultaneously, it achieves automated updates of 2D design changes in the 3D model, eliminating the need for manual modification of 3D component parameters and improving the efficiency of design changes.

[0139] It should be noted that the modification information of the first element in the two-dimensional model is obtained first, and then the fourth target component in the three-dimensional model is initially located based on the established relationship. The spatial information of the fourth target component is combined to verify the accuracy of the location. Finally, the modification information is updated to the design information corresponding to the fourth target component. This achieves the technical effect of automating and accurately synchronizing two-dimensional design changes in the three-dimensional model, avoiding the inefficiency and errors of manually modifying three-dimensional components, ensuring that the two-dimensional and three-dimensional design information are always consistent, and improving the efficiency and accuracy of design changes.

[0140] The embodiments provided in this application obtain target design information for a first graphic element, wherein the target design information is used to indicate the modified design information; based on the association relationship and spatial information, the target design information is determined to be the design information corresponding to the fourth target component. By first obtaining the modification information of the first graphic element in the two-dimensional model, then relying on the established association relationship to initially locate the fourth target component in the three-dimensional model, and combining the spatial information of the fourth target component to verify the accuracy of the location, the modification information is finally updated to the design information corresponding to the fourth target component. This achieves the technical effect of automating and accurately synchronizing two-dimensional design changes in the three-dimensional model, avoiding the inefficiency and errors of manually modifying three-dimensional components, ensuring that the two-dimensional and three-dimensional design information are always consistent, and improving the efficiency and accuracy of design changes.

[0141] As an optional solution, in order to better understand the process of the above-mentioned three-dimensional model design information filling method, the following describes the execution flow of the above-mentioned server fault prediction method in conjunction with optional embodiments, but it is not intended to limit the technical solution of the embodiments of this application.

[0142] This embodiment proposes a method for adding structured drawing information to a 3D model. The specific steps are as follows:

[0143] 1) Convert the standard drawing into a 3D digital model of a single layer and single component (before this conversion, select a point on the plane as the corresponding coordinates, set a number in the dialog box as the layer elevation, and optionally set a number in the dialog box as the plane rotation value). The generated standard drawing includes information data for several independent structural components. The data for a single independent component includes the design element information (also known as standard element information) corresponding to the component, the outer contour information of the component, and other manufacturing attribute information of the component (collectively referred to as standard design data information).

[0144] 2) Obtain the created 3D model data from the existing 3D model using the API (REVIT, TS3D) or standard data interface file.

[0145] 3) The outer contour data of the 3D digital model generated from the flat drawing is matched one-to-one with the existing 3D model data based on the components.

[0146] 4) After matching, based on the interface provided by the 3D modeling software, including API or standard data interface, write the 2D recognition standard graphic element information and standard design data based on the components into the 3D model.

[0147] Currently, structural information acquisition primarily relies on engineers reading drawings and then manually entering the data. This involves placing 2D drawings under a 3D model for data input or matching, but the data needs to be acquired from 2D data within the 3D platform for recognition, which can lead to data distortion. Furthermore, the interactive features of current 3D model software are less convenient than those of 2D software. Additionally, algorithms need to be reconstructed within the 3D software.

[0148] However, inputting structural construction drawings and component information into Revit is a complex and time-consuming process. Typically, comparing CAD construction drawings with the Revit model requires repeated manual operations, resulting in high labor costs and a high risk of errors. This embodiment utilizes image recognition technology to automatically improve the efficiency of inputting 3D Revit data.

[0149] S7-1 identifies graphic elements in the CAD drawing. After identifying the beam drawing, run the "Generate Beam trvt" command. Select the export file directory and name, as well as supplementary information such as floor elevation. Next, after identifying the drawing, generate the interface file, specify the alignment point, and finally generate the file.

[0150] S7-2, import data into the Revit model. A pop-up dialog box will appear. Then click the alignment point to complete the import of data, 2D drawings, and the model. It should be noted that this process imports not only the components and assigns them attributes, but also the design graphic information such as design text and logos.

[0151] The technical process of implementation, such as Figure 3 As shown, it includes:

[0152] S302, Obtain CAD drawing element information;

[0153] S304 assigns CAD drawing element information according to professional rules and converts it into component classification information; at the same time, it marks the data source of the component classification information.

[0154] S306, combine component classification information to obtain multiple individual components and information groups of individual components in the component group;

[0155] S308 uses the association between CAD drawing elements and structural information to reversely represent the component number and information category corresponding to the drawing element;

[0156] S310, using coordinate rules to match the information of a single component group with the REVIT model information, so that the REVIT model components can obtain the structural information of graphic element analysis;

[0157] S312, copy the graphic element information to the corresponding position of the 3D model, and establish the association between the graphic element and the identification component and the identification component and the REVIT model component based on the established association between the graphic element and the identification component and the REVIT model component.

[0158] S314 In REVIT, the graph generation logic is used to prioritize the association between graph elements and the model.

[0159] Optionally, in this embodiment, character group recognition is performed based on CAD to obtain graphic elements in the two-dimensional plan drawing. Then, the graphic elements in the two-dimensional plan drawing are identified to form components and generate attribute information. The information source is obtained through drawing recognition. The graphic elements are then digitally identified in reverse. Next, based on interface data provided by Revit, domestic TS3D, and Glodon GTJ (data that can reproduce the shape of the digital model), the planar data created from the two-dimensional plan drawing is analyzed with this data. For beams, firstly, all beams in the vicinity are searched by reinforcement location. Secondly, the correct beams are precisely matched using the set found in the first step. Through the three-dimensional software structure, the graphic element information is written to the corresponding position in the three-dimensional model. Optionally, based on the established association between graphic elements and identified components, and the association between identified components and Revit model components, by establishing the association between graphic elements and Revit model components, the graphic element data and model data can be kept consistent, and subsequent linkage modifications can be achieved using Revit's mechanisms.

[0160] Optionally, in this embodiment, coordinate rules and fuzzy correction rules (with certain data tolerance and data uniqueness judgment under professional rules, etc.) are used to match the information of a single component group with the information of the REVIT model. Optionally, the structural information of the REVIT model components is copied to obtain the structural information of the graphic element analysis. Among them, the fuzzy matching of beams includes the following steps:

[0161] S8-1, cache beam data; where S1 includes:

[0162] S8-1-1, take the midpoints X and Y of the beam. Since a single-layer matching is used, Z is ignored.

[0163] S8-1-2, X and Y are rounded within a fixed range (parameter: 500mm), constructing a string (X, Y, 0) as the key;

[0164] S8-1-3, group beam IDs with the same Key together.

[0165] S8-2, find the beam based on the data; where S2 includes:

[0166] S8-2-1, Take the midpoint of the two-dimensional data beam and calculate the fuzzy key;

[0167] S8-2-2: Search for Revit beams in the cache based on the key. The first search is a fuzzy search, which can find multiple beams.

[0168] S8-2-3, perform detailed matching based on the Revit beams found through fuzzy matching.

[0169] S8-3, detailed matching; where S3 includes:
