Description

[0001] The present invention relates to the technical field of computer-aided design, and in particular to a method for generating beam reinforcement information in a BIM model based on a beam plan construction drawing. Background Art

[0002] In the prior art, CAD software and BIM software can be used to construct CAD drawings (for example, beam plan construction drawings) and BIM models of the same building object. Due to the use of different types of software, the information on the CAD drawings and the information in the BIM model are somewhat different; for example, the beam reinforcement information in the CAD drawings is expressed in the form of text annotations, while the beam reinforcement information in the BIM model is stored in the beam component in the form of data. Due to the different information expression and storage methods of the two, the beam reinforcement information in the CAD drawings and the beam reinforcement information in the BIM model cannot interact. In the prior art, designers are required to manually add beam reinforcement information to each beam component in the BIM model based on the beam reinforcement information in the CAD drawings. The process is complicated and the workload is large.

[0003] Therefore, how to automatically import the beam reinforcement information in the CAD drawing into the BIM model has become a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0004] The purpose of the present invention is to provide a method for generating beam reinforcement information in a BIM model based on a beam plan construction drawing, which can more accurately and efficiently add beam annotations and beam reinforcement information to the BIM model.

[0017] The target candidate characters that meet the preset distance rule are combined to form the concentrated annotated characters.

[0018] Optionally, the step of acquiring a beam plan construction drawing and a BIM model having a corresponding relationship, and identifying a beam annotation graphic element containing beam reinforcement information from the beam plan construction drawing includes:

If so, combine the in-situ annotation text and the segmented annotation line to form the beam annotation graphic element. If not, use the in-situ annotation text as the beam annotation graphic element.

[0022] Optionally, determining the target beam component belonging to the beam annotated component according to the positional relationship between the beam annotated component and the beam component in the BIM model includes:

[0023] For a beam annotated component whose annotation type is in-situ annotation, determining a candidate beam component closest to the beam annotated component from the BIM model;

[0024] When the beam annotation component is parallel to the candidate beam component and the distance between the beam annotation component and the candidate beam component is less than a preset threshold, the candidate beam component is used as the target beam component.

[0046] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0047] Embodiment 1

[0048] The embodiment of the present invention provides a method for generating beam reinforcement information in a BIM model based on a beam flat method construction drawing, such as Figure 1 As shown, the method specifically comprises the following steps:

[0049] Step S101: Obtain a beam plan construction drawing and a BIM model having a corresponding relationship, and identify beam annotation elements containing beam reinforcement information from the beam plan construction drawing.

[0050] Among them, the beam leveling method construction drawing and the BIM model are both used to represent the same building object; the beam leveling method construction drawing is a CAD (Computer Aided Design) two-dimensional drawing, and the beam leveling method construction drawing includes graphics (graphics composed of lines) used to represent each building component (for example, columns, beams, walls, and plates) and graphics used to represent annotations (centralized annotations and in-situ annotations); and BIM (Building Information Modeling) is a three-dimensional building model, and the BIM model includes model components used to represent each building component, but does not include model components used to represent annotations in the BIM model. Through this embodiment, an annotation component corresponding to the annotation graphics in the beam leveling method construction drawing can be automatically generated in the BIM model, and the annotation component generated in the BIM model can be associated with the beam component already existing in the BIM model, thereby achieving the effect of automatically adding the beam reinforcement information in the beam leveling method construction drawing to the BIM model.

[0051] In addition, since the beam annotation elements include: centralized annotation elements and in-situ annotation elements, and the in-situ annotation elements include: segmented annotation and non-segmented annotation, the present embodiment provides two different beam annotation element recognition methods, as described below, steps A1 to A3 are recognition methods for centralized annotation elements, and steps B1 to B3 are recognition methods for in-situ annotation elements.

[0052] Specifically, step S101 includes:

[0053] Step A1: identifying a concentrated marking leader line from the beam leveling method construction drawing, and identifying candidate characters located within a first set range around the concentrated marking leader line;

[0054] Among them, the concentrated annotation is composed of annotation leader lines and annotation text. In this embodiment, the annotation leader lines can be identified first, and then the annotation text can be identified based on the annotation leader lines. Finally, the identified annotation leader lines and annotation text are combined to form a concentrated annotation.

[0055] Step A2: selecting concentrated annotation characters that match the concentrated annotation guide from the candidate characters according to the positional relationship between the candidate characters and the concentrated annotation guide;

[0056] Preferably, step A2 specifically includes:

[0057] Step A21: Filter out target candidate characters from all candidate characters, which are perpendicular to the concentrated marking leader line and whose projection of the upper left vertex of the characters to the concentrated marking leader line is located on the concentrated marking leader line;

[0058] Step A22: determining whether the line spacing between the target candidate characters and the distance from the target candidate characters to the concentrated marking leader line meet a preset distance rule;

[0059] Step A23: combining the target candidate characters that satisfy the preset distance rule to form the concentrated annotated characters.

[0060] Step A3: combining the concentrated annotation leader and the concentrated annotation text to form the beam annotation graphic element;

[0061] It should be noted that since there is no centralized marking module in the beam leveling method construction drawing, the centralized module cannot be directly identified from the beam leveling method construction drawing; the centralized marking in the beam leveling method construction drawing is expressed in the form of a marking leader line and multiple lines of text. This embodiment utilizes the style features of the centralized marking to identify the various graphics elements (leader lines and multiple lines of text) belonging to the same centralized marking from the beam leveling method construction drawing and combine the identified graphics elements to form a centralized marking.

[0062] Furthermore, step S101 further includes:

[0063] Step B1: identifying a target beam element from the beam flat method construction drawing, and identifying candidate characters located within a second set range around the target beam element;

[0064] Preferably, step B1 specifically includes:

[0065] The candidate text closest to the upper boundary line of the target beam element is identified, and the candidate text closest to the lower boundary line of the target beam element is identified.

[0066] Step B2: selecting in-situ annotation characters belonging to the target beam element from the candidate characters according to the positional relationship between the candidate characters and the target beam element;

[0067] Preferably, step B2 comprises:

[0068] Step B21: Filter out target candidate characters from all candidate characters, which are parallel to the target beam primitive and whose projections to the target beam primitive are located on the target beam primitive;

[0069] Step B22: determining whether the line spacing between the target candidate characters and the distance from the target candidate characters to the target beam element meet a preset distance rule;

[0070] Step B23: combining the target candidate characters that satisfy the preset distance rule to form the in-situ annotated characters.

[0071] Step B3: determining whether there is a segmented annotation line within a third set range around the in-situ annotation text; if so, combining the in-situ annotation text and the segmented annotation line to form the beam annotation graphic element; if not, using the in-situ annotation text as the beam annotation graphic element;

[0072] It should be noted that if Figure 2 As shown, it is a schematic diagram of segmented annotation. The only difference between segmented annotation and non-segmented annotation is that segmented annotation has more segmented annotation lines than non-segmented annotation. The segmented annotation line is composed of five line segments and is used to limit the annotation position. In this embodiment, the style characteristics of the segmented annotation line are used to identify five line segments used to represent the segmented annotation line from the beam leveling method construction drawing, and these five line segments are combined into a segmented annotation line; if there is a segmented annotation line in the attachment of the in-situ annotation text, the in-situ annotation text and the segmented annotation line are combined to form a segmented annotation; if there is no segmented annotation line in the attachment of the in-situ annotation text, the in-situ annotation text is combined into a segmented annotation.

[0073] Step S102: according to the position of the beam annotation element in the beam plan construction drawing, adding a beam annotation component corresponding to the beam annotation element at a corresponding position in the BIM model.

[0074] Since there is no concept of annotation module in the beam flat method construction drawing, the only way is to combine the identified elements from the beam flat method construction drawing into annotation modules in the above method. However, there is the concept of annotation module (i.e. annotation component) in the BIM model, so the corresponding beam annotation component can be created in the BIM model according to the beam annotation elements identified in the beam flat method construction drawing, and the beam reinforcement information is included in the beam annotation component.

[0075] Step S103: determining a target beam component belonging to the beam annotated component according to the positional relationship between the beam annotated component and the beam component in the BIM model.

[0076] Although a beam annotation component is created in the BIM model in step S102, the association relationship between the created beam annotation component and the existing beam component has not yet been established, so it is necessary to find the target beam component associated with the beam annotation component from the BIM model. In addition, for centralized annotation and in-situ annotation, this embodiment provides two association methods, as described below, steps C1 to C2 are association methods for in-situ annotation, and steps D1 to D3 are association methods for centralized annotation.

[0077] Specifically, step S103 includes:

[0078] Step C1: for a beam annotated component whose annotation type is in-situ annotation, determining a candidate beam component closest to the beam annotated component from the BIM model;

[0079] Step C2: when the beam annotation component is parallel to the candidate beam component and the distance between the beam annotation component and the candidate beam component is less than a preset threshold, the candidate beam component is used as the target beam component.

[0080] Furthermore, step S103 further includes:

[0081] Step D1: for beam annotated components whose annotation type is centralized annotation, select candidate beam components from the BIM model, and determine other candidate beam components whose positional relationships with the candidate beam components satisfy a preset beam string rule from the BIM model to form a beam string group;

[0082] Preferably, the preset beam string rule is: the distance between any two adjacent candidate beam components in the beam string is less than a preset distance value, and the angle between any two adjacent candidate beam components is greater than a preset threshold (for example, greater than 135 degrees).

[0083] Step D2: traversing each candidate beam component in the beam string group from one end to the other end in sequence, and determining whether the currently traversed candidate beam component is connected to the concentrated annotation leader of the beam annotation component;

[0084] like Figure 3 As shown, this is a schematic diagram of concentrated marking. Since the concentrated marking lead line does not necessarily pass completely through the beam component in actual application, there may be a certain error.

[0085] Step D3: If yes, determine N candidate beam components from the beam string group as the target beam component according to the number of beams N contained in the concentrated annotation text of the beam annotation component; if no, continue to traverse the next candidate beam component.

[0086] Preferably, the step of determining N candidate beam components from the beam string group as the target beam components according to the number of beams N contained in the concentrated annotation text of the beam annotation component specifically includes:

[0087] Determine, from the beam string group, a central candidate beam component connected to the concentrated annotation leader of the beam annotation component;

[0088] Counting the number M of candidate beam components in the beam string group that are located before the central candidate beam component;

[0089] If M is greater than or equal to N, the central candidate beam component and all candidate beam components in the beam string group located before the central candidate beam component are taken as the target beam component;

[0090] If M is less than N, then determine the (NM-1) supplementary candidate beam components in the beam string group that are located after the central candidate beam component, and take the central candidate beam component, all candidate beam components in the beam string group that are located before the central candidate beam component, and the supplementary candidate beam components as the target beam components.

[0091] It should be noted that the in-situ marking only belongs to one beam component, while the concentrated marking will belong to multiple beam components. Therefore, for the concentrated marking, it is necessary to determine all the beam components corresponding to the concentrated marking based on the number of beams contained in the marked text in the concentrated marking.

[0092] Step S104: adding the beam reinforcement information in the beam annotation component to the attribute information of the target beam component.

[0093] Specifically, step S104 includes:

[0094] In the BIM model, the identification information ID of the beam annotation component is written into the attribute information of each target beam component respectively.

[0095] like Figure 4 As shown, in this embodiment, different annotation recognition methods are provided for different annotation types. First, various types of annotation elements are identified from the CAD drawings, and corresponding annotation components are created in the BIM model. Finally, the annotation components are associated with the original beam components in the BIM model, so that the beam reinforcement information in the CAD drawings is imported into the BIM model.

[0096] In this embodiment, the beam annotations in the beam plan method construction drawing are automatically added to the BIM model, and the beam reinforcement information is automatically added to the beam components in the BIM model based on the beam annotations added to the BIM model. Therefore, designers are no longer required to manually add beam annotations and beam reinforcement information to the BIM model based on the beam annotations in the beam plan method construction drawing. This not only improves work efficiency, but also allows for more accurate addition of beam annotations and beam reinforcement information to the BIM model.

[0097] Embodiment 2

[0098] The embodiment of the present invention provides a device for generating beam reinforcement information in a BIM model based on a beam flat method construction drawing, such as Figure 5 As shown, the device specifically includes the following components:

[0099] The acquisition module 501 is used to acquire a beam plan construction drawing and a BIM model having a corresponding relationship, and identify beam annotation elements containing beam reinforcement information from the beam plan construction drawing;

[0100] An adding module 502 is used to add a beam annotation component corresponding to the beam annotation element at a corresponding position in the BIM model according to the position of the beam annotation element in the beam flat method construction drawing;

[0101] A determination module 503 is used to determine a target beam component belonging to the beam annotation component according to a positional relationship between the beam annotation component and the beam component in the BIM model;

[0102] The association module 504 is used to add the beam reinforcement information in the beam annotation component to the attribute information of the target beam component.

[0103] Specifically, the acquisition module 501 includes:

[0104] A recognition unit, used to recognize concentrated marking leaders from the beam leveling method construction drawing, and recognize candidate characters located within a first set range around the concentrated marking leaders;

[0106] A combining unit is used for combining the concentrated annotation leader and the concentrated annotation text to form the beam annotation graphic element.

[0107] Furthermore, the screening unit is specifically used for:

[0108] Filter out target candidate characters from all candidate characters, which are perpendicular to the concentrated marking leader line and whose projection of the upper left vertex of the characters to the concentrated marking leader line is located on the concentrated marking leader line;

[0109] Determine whether the line spacing between the target candidate characters and the distance from the target candidate characters to the concentrated marking leader line meet a preset distance rule;

[0110] The target candidate characters that meet the preset distance rule are combined to form the concentrated annotated characters.

[0111] Specifically, the acquisition module 501 is further used for:

[0112] Identify a target beam element from the beam flat method construction drawing, and identify candidate characters located within a second set range around the target beam element;

[0113] According to the positional relationship between the candidate characters and the target beam element, the in-situ annotation characters belonging to the target beam element are selected from the candidate characters;

[0114] Determine whether there is a segmented annotation line within a third set range around the in-situ annotation text. If so, combine the in-situ annotation text and the segmented annotation line to form the beam annotation graphic element. If not, use the in-situ annotation text as the beam annotation graphic element.

[0115] Furthermore, the determination module 503 is specifically configured to:

[0116] For a beam annotated component whose annotation type is in-situ annotation, determining a candidate beam component closest to the beam annotated component from the BIM model;

[0117] When the beam annotation component is parallel to the candidate beam component and the distance between the beam annotation component and the candidate beam component is less than a preset threshold, the candidate beam component is used as the target beam component.

[0118] Furthermore, the determination module 503 is further configured to:

[0119] For the beam annotated components whose annotation type is centralized annotation, candidate beam components are selected from the BIM model, and other candidate beam components whose positional relationships with the candidate beam components satisfy a preset beam string rule are determined from the BIM model to form a beam string group;

[0120] Traversing each candidate beam component in the beam string group from one end to the other end in sequence, and determining whether the currently traversed candidate beam component is connected to the concentrated annotation leader of the beam annotation component;

[0121] If so, N candidate beam components are determined from the beam string group as the target beam components according to the number of beams N contained in the concentrated annotation text of the beam annotation component; if not, the next candidate beam component is traversed continuously.

[0122] Furthermore, when the determination module 503 implements the step of determining N candidate beam components from the beam string group as the target beam component according to the number of beams N contained in the concentrated annotation text of the beam annotation component, it specifically includes:

[0123] Counting the number M of candidate beam components in the beam string group that are located before the central candidate beam component;

[0124] If M is greater than or equal to N, the central candidate beam component and all candidate beam components in the beam string group located before the central candidate beam component are taken as the target beam component;

[0125] If M is less than N, then determine the (NM-1) supplementary candidate beam components in the beam string group that are located after the central candidate beam component, and take the central candidate beam component, all candidate beam components in the beam string group that are located before the central candidate beam component, and the supplementary candidate beam components as the target beam components.

[0126] Furthermore, the association module 504 is specifically used for:

[0127] In the BIM model, the identification information ID of the beam annotation component is written into the attribute information of each target beam component respectively.

[0128] Through this embodiment, it is possible to automatically add beam annotations in the beam plan method construction drawing to the BIM model, and to automatically add beam reinforcement information to the beam components in the BIM model based on the beam annotations added to the BIM model. Therefore, it is no longer necessary for designers to manually add beam annotations and beam reinforcement information to the BIM model based on the beam annotations in the beam plan method construction drawing, which not only improves work efficiency but also allows for more accurate addition of beam annotations and beam reinforcement information to the BIM model. This embodiment can accurately identify the beam annotations and beam reinforcement information in the beam plan method construction drawing and convert them into component information in the BIM model.
