These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. It should be noted that this application... Figures 2-9The component net height analysis method provided in the embodiment has a computer device as an execution subject, and can also be a component net height analysis device. The component net height analysis device can be part or all of the computer device in the form of software, hardware or a combination of software and hardware. In the following method embodiments, the execution subject is taken as an example of the computer device.

[0054] In one embodiment, as shown in Figure 2 A component net height analysis method is provided, including the following steps:

[0055] S201, obtaining a building information model, and determining at least one target region according to region attribute information in the building information model.

[0056] The attribute information of the building information model (BIM) refers to the attribute information of each component and each part in the building information model, for example, including a type label, which can be a pipeline, a room, a corridor, etc. In addition, the attribute information can also include ID, area, length, position coordinates and other parameters, for example, the area of the room with ID 01 is 25 m 2 , etc.

[0057] In this embodiment, the computer device can obtain all regions with the label of room as target regions. Alternatively, the computer device can also obtain all room regions with the ID in a preset range as target regions according to the ID, for example, obtain the rooms with ID in [01-05] as target regions, and then the computer device determines the regions formed by the rooms with ID 01, 02, 03, 04 and 05 as target regions according to the ID of each room. Alternatively, the computer device can also determine the spaces in a specified range as target regions according to the space label of the building information model. Alternatively, the computer device can also obtain all rooms with the preset elevation in the building information model as target regions according to the preset elevation. Optionally, after determining the target regions, the net height parameters of the target regions can also be determined, which is not limited in this embodiment.

[0058] 202, determining a target pipeline component in at least one target region according to the enclosing line segment of the target region and the positioning line of the pipeline component in the building information model.

[0059] The enclosing line segment refers to the line segment corresponding to the enclosing region formed by the projection of the target region in the BIM model to a two-dimensional plane.

[0060] In this embodiment, the computer device can traverse each target region, determine all pipe components involved in each target region, project the target region to a two-dimensional plane, for example, the XOY plane, to obtain the target region on the two-dimensional plane, thereby determining the enclosing line segment of the target region, project the positioning line of the pipe component to the two-dimensional plane as well, and determine the target pipe component actually in the target region according to the line segment obtained by projecting the positioning line of the pipe component to the two-dimensional plane and the enclosing line segment of the target region.

[0061] S203, determine an analysis result of the target pipe component according to the bottom elevation of the target pipe component and the preset net height of the target region; the analysis result indicates whether the target pipe component is reasonable.

[0062] The bottom elevation of the target pipe component can be directly obtained from the attribute information of each component of the BIM model; the preset net height of the target region is the same net height set by the computer device for all target regions after determining the target regions.

[0063] In this embodiment, the computer device analyzes according to the preset net height of the target region and the obtained bottom elevations of the target pipes, for example, the computer device can directly compare the bottom elevations of the target pipes with the preset net height of the target region, determine the target pipe whose bottom elevation is less than the preset net height of the target region as an unreasonable pipe component, and determine the target pipe whose bottom elevation is greater than or equal to the preset net height of the target region as a reasonable pipe component. Alternatively, the computer device can also calculate the difference between the bottom elevation of each target pipe and the preset net height of the target region, if the difference is within the preset difference range, the pipe component is determined as a reasonable pipe component; if the difference is outside the preset difference range, it is further determined whether the bottom elevation of the pipe component is less than the preset net height of the target region, if yes, the pipe component is determined as an unreasonable pipe component; if no, the pipe component is determined as a reasonable pipe component, which is not limited in this embodiment.

[0064] In the method, the computer device can analyze and judge the net height of each component in the building information model based on the attribute information of each component in the building information model, so as to obtain the result whether the net height of each component meets the requirement or is reasonable, realize the pre-analysis of the net height of the component based on the building information model, and improve the component in the building information model which is not reasonable based on the analysis result. In addition, the net height analysis of the component is based on the building information model, and the analysis result is relatively accurate because the parameters of each component in the building information model are objective parameters.

[0065] Optionally, the computer device can determine whether the pipe component is in the target area by the method provided in the following embodiments. In one of the optional embodiments, as shown in Figure 3 the method for determining the target pipe component in the at least one target area according to the enclosing line segment of the at least one target area and the positioning line of the pipe component in the building information model, comprises:

[0066] For each target area in the building model, the operations of steps 301 to 303 are performed.

[0067] S301, obtaining the enclosing line segment of the target area.

[0068] In the embodiment, the computer device can realize the operation of the BIM model through the revit plug-in. For example, when the target area is a room, the computer device can obtain the closed target area by calling the room.GetBoundarySegments method in the revit plug-in, so as to construct the IList <boundarysegment>Get the curve by the BoundarySegment method, and then pass the curve list into Curveloop.create to get the target area's enclosed area.

[0069] S302, determine the candidate pipe components whose relative elevations of pipe components in the building model are equal to the current elevation of the target area.

[0070] The pipe components can include bridge, air pipe, water pipe, etc.

[0071] In this embodiment, all pipe components in the BIM model are obtained, and the relative elevations of all pipe components are obtained. According to the comparison between the relative elevations of each pipe component and the current elevation of the target area, the pipe component whose relative elevation is equal to the current elevation of the target area is determined as the candidate pipe component. The relative elevation can be directly obtained from the attribute information of each pipe component in the BIM model, and the current elevation of the target area is the elevation set when the target area is obtained. Here, the computer device needs to screen all pipe components in the BIM model, that is, the computer device screens the pipe components that meet the requirements (relative elevation equal to current elevation) according to the relative elevations of the pipe components, instead of indiscriminately analyzing all pipe components in the BIM model, which improves the accuracy of the net height analysis of the pipe components.

[0072] S303, determine the target pipe components of the target area according to the enclosing line segments of the target area and the positioning lines of the candidate pipe components.

[0073] The positioning lines of the candidate pipe components can be obtained through the location attribute of each pipe component. In this embodiment, the computer device determines the target area to which each pipe component belongs or determines whether each pipe component is in its corresponding target area according to the positioning lines of the candidate pipe components after the determination and the enclosing line segments of the target area that have been determined.

[0074] Alternatively, one of the implementation methods for determining whether the pipe component is in the target area is as shown in Figure 4 According to the enclosing line segments of the target area and the positioning lines of the candidate pipe components, the target pipe components of the target area are determined, including:

[0075] S401, project the positioning lines of the candidate pipe components and the enclosing line segments of the target area to a two-dimensional plane, and determine all intersection points of the positioning lines of the candidate pipe components and the enclosing line segments on the two-dimensional plane.

[0076] In the embodiment, the computer device projects the enclosing region of the target region and the positioning line of the candidate pipe component in the BIM model into a two-dimensional plane, for example, into the xoy plane, and obtains all intersection points of the positioning line of the candidate pipe component and the enclosing line segment in the two-dimensional plane based on the xoy plane.

[0077] S402, determining the number of line segments obtained by the intersection of the positioning line of the candidate pipe component and the enclosing line segment according to the intersection points.

[0078] In the embodiment, all intersection points of the positioning line of the candidate pipe component and the enclosing line segment in the two-dimensional plane are determined, and the computer device can determine the number of line segments between the intersection points formed by a certain pipe component according to each intersection point.

[0079] S403, determining the target pipe component in the target region according to the number of line segments.

[0080] In the embodiment, the computer device determines whether the current candidate pipe component is in the target region according to the number of line segments.

[0081] Optionally, if the number of line segments is greater than a preset value, the candidate pipe component is determined as the target pipe component in the target region; if the number of line segments is equal to the preset value, the midpoint position of the line segment obtained by the intersection of the positioning line of the candidate pipe component and the enclosing line segment is determined, and if the midpoint position is in the region of the enclosing line segment, the candidate pipe component is determined as the target pipe component in the target region.

[0082] In the embodiment, for example, the preset value can be 1, if the computer device determines that the number of line segments formed by the intersection of the positioning line of the current pipe component and the enclosing line segment is greater than 1, it is determined that the current pipe component is in the target region; if the computer device determines that the number of line segments formed by the intersection of the positioning line of the current pipe component and the enclosing line segment is equal to 1, the midpoint position of the line segment is determined according to the current line segment, and whether the current pipe component is in the enclosing region is determined according to whether the midpoint position is in the enclosing region, if the midpoint position is in the region of the enclosing line segment, the current pipe component is determined to be in the target region, which is not limited in the embodiment.

[0083] In the embodiment, the computer device can determine the pipe component in the target region through the positioning line of the pipe component and the enclosing line segment of each target region, so as to more accurately analyze the pipe component in the target region, reduce the influence of unnecessary data, and improve the accuracy of the analysis result.

[0084] In one of the optional embodiments, the analysis result of the pipe component is determined according to the bottom elevation of the target pipe component and the preset net height of the target region, including:

[0085] If the bottom elevation of the target pipe component is less than the preset net height of the target area, it is determined that the target pipe component is abnormal; if the bottom elevation of the target pipe component is greater than or equal to the preset net height of the target area, it is determined that the target pipe component is normal.

[0086] In this embodiment, the computer device obtains the bottom elevation of each target pipe component, compares the bottom elevation of each target pipe component with the preset net height of the target area, and determines that the target pipe component is abnormal if the bottom elevation of the target pipe component is less than the preset net height of the target area, and determines that the target pipe component is normal otherwise. For details, refer to Figure 5 Figure 5 Two pipe components with bottom elevations less than the preset net height of the target area are given.

[0087] Optionally, the pipe component can be a bridge, an air pipe, a water pipe, etc. The bottom elevation of the bridge and the air pipe can be directly obtained from the BIM model. The method element.GetDoubleValue(BuiltInParameter.RBS_CTC_BOTTOM_ELEVATION) is called to obtain the bottom elevation of the bridge and the air pipe.

[0088] Optionally, in the case of a water pipe, the bottom elevation of the pipe component can be determined in the following manner:

[0089] The bottom elevation of the water pipe is calculated according to the pipe bottom elevation, the reference elevation, the outer diameter and the inner diameter.

[0090] In this embodiment, the bottom elevation of the water pipe = pipe bottom elevation - reference elevation of the component - (outer diameter - inner diameter) / 2, wherein the pipe bottom elevation, the reference elevation of the component, the outer diameter and the inner diameter can be obtained from the BIM model. For example, the reference elevation of the component is obtained by the method doc.GetElement(element.GetElementId(BuiltInParameter.RBS_START_LEVEL_PARAM)) as Level, the pipe bottom elevation is obtained by the method element.GetDoubleValue(BuiltInParameter.RBS_PIPE_INVERT_ELEVATION), the outer diameter is obtained by the method element.GetDoubleValue(BuiltInParameter.RBS_PIPE_OUTER_DIAMETER), and the inner diameter is obtained by the method element.GetDoubleValue(BuiltInParameter.RBS_PIPE_INNER_DIAM_PARAM), which is not limited in this embodiment. ​

[0091] In this embodiment, the computer device can obtain the bottom elevation of each target pipe component based on the BIM model, and determine the unreasonable pipe component based on the bottom elevation of the target pipe component and the preset net height of the target area, i.e., determine the abnormal pipe component. This scheme can simply and conveniently achieve the purpose of accurately locating the abnormal pipe component.

[0092] After determining the abnormal pipe component, further, the computer device can also mark the abnormal pipe component in the BIM model. In one of the optional embodiments, as shown in Figure 6 The method further includes:

[0093] S501, adding an abnormal identifier in the attribute information of the abnormal target pipe component.

[0094] The abnormal identifier can be a specified color or a specified style of the abnormal target pipe component, or a label added to the abnormal target pipe component for indicating the abnormality. The label can be displayed in a folded manner in the display interface of the BIM model, i.e., the abnormal identifier is displayed when the target pipe component is triggered to be viewed.

[0095] S502, adding the abnormal identifier of the abnormal target pipe component in the building information model according to the abnormal identifier of the abnormal target pipe component, and updating the building information model.

[0096] In this embodiment, after determining the updated attribute information of the abnormal target pipe component, the BIM model is updated according to the attribute information of the abnormal target pipe component, i.e., the abnormal identifier of the abnormal target pipe component is displayed in the BIM model. As shown in Figure 7 Figure 7 The left side shows a schematic diagram of the abnormal water pipe.

[0097] S503, displaying the updated building model in a target view.

[0098] The target view is a specified other view. Before displaying the BIM model, the computer device can create a view of other dimensions for the BIM model, or create a view specified by the user, and display the BIM model in the target view. Optionally, the computer device can also output an analysis report of the BIM model according to the updated building model and the analysis result of the target pipe component. The analysis report includes the local BIM model where the abnormal target pipe component is located, the area where the abnormal target pipe component is located, the state of the abnormal target pipe component, the net height of the abnormal target pipe component, and the axis net position of the abnormal target pipe component, etc. The analysis report can refer to Figure 8

[0099] ​​Optionally, the method for determining the axis net position of the target pipe component comprises:

[0100] acquiring the midpoint of the center line of the abnormal pipe component; acquiring the horizontal axis net and the vertical axis net in the building model; traversing each horizontal axis net to determine the closest horizontal axis net to the center point of the target pipe component, and determining the position of the target pipe component on the horizontal axis net according to the closest horizontal axis net; traversing each vertical axis net to determine the closest vertical axis net to the center point of the target pipe component, and determining the position of the target pipe component on the vertical axis net according to the closest vertical axis net.

[0101] In this embodiment, the computer device determines the midpoint of the center line of the abnormal pipe component, acquires all the axis nets in the BIM model, groups the axis nets, groups the axis nets parallel to the x-axis into a horizontal group to obtain the horizontal axis net, and groups the axis nets parallel to the y-axis into a vertical group to obtain the vertical axis net. The horizontal axis net is traversed to determine the shortest line from the center point of the abnormal pipe component to the infinite extension line of the horizontal axis net to obtain the position of the target pipe component on the horizontal axis net; the vertical axis net is traversed to determine the shortest line from the center point of the abnormal pipe component to the infinite extension line of the vertical axis net to obtain the position of the target pipe component on the vertical axis net. In the analysis report, the axis net position of the abnormal pipe component can be expressed in the form of horizontal axis net position and vertical axis net position.

[0102] In this embodiment, the computer device can determine the abnormal target pipe component in the BIM model according to the analysis result. In order to more intuitively feed back the abnormal pipe component to the user, the computer device can update the identification of the abnormal pipe component to the BIM model, and output an analysis report according to the related information, so as to optimize the intuitive understanding of the abnormal pipe component by the user.

[0103] In order to better illustrate the above method, as shown in Figure 9 the embodiment provides a component net height analysis method, which specifically comprises:

[0104] S101, acquiring a building information model, and determining at least one target region according to region attribute information in the building information model;

[0105] S102, acquiring a surrounding line segment of each target region;

[0106] S103, determining a candidate pipe component in the building model, the relative elevation of which is equal to the current elevation of the target region;

[0107] S104, determining a target pipe component of each target region according to the surrounding line segment of each target region and the positioning line of the candidate pipe component;

[0108] S105, if the bottom elevation of the target pipe component is less than the preset net height of the target area, it is determined that the target pipe component is abnormal;

[0109] S106, if the bottom elevation of the target pipe component is greater than or equal to the preset net height of the target area, it is determined that the target pipe component is normal;

[0110] S107, adding an abnormality identifier to the attribute information of the abnormal target pipe component;

[0111] S108, according to the abnormality identifier of the abnormal target pipe component, adding the abnormality identifier of the abnormal target pipe component in the building information model, and updating the building information model;

[0112] S109, displaying the updated building model in the target view, and outputting an analysis report of the abnormal target pipe component.

[0113] In the embodiment, the computer device can analyze and judge the net height of each component in the building information model based on the attribute information of each component in the building information model, so as to obtain the result whether the net height of each component meets the requirement or is reasonable, thereby realizing the pre-analysis of the net height of the component based on the building information model. Based on the analysis result, the component in the building information model which is unreasonable can be improved. Moreover, the analysis of the net height of the component based on the building information model is more accurate because the parameters of each component in the building information model are objective parameters.

[0114] The component net height analysis method provided by the above embodiment has similar implementation principles and technical effects to the method embodiment, which will not be described here.

[0115] It should be understood that, although Figures 2-9 the steps in the flowchart are displayed in sequence according to the arrows, these steps are not necessarily executed in sequence according to the arrows.

Moreover, Figures 2-9 at least part of the steps in the flowchart can include multiple steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least part of other steps or steps or stages in other steps.
