[0052] Those skilled in the art will understand that Figure 1The structure shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the computer device to which the present application is applied. Specific computer devices may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements.

[0053] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. 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. The embodiments of this application will be described below with reference to the accompanying drawings.

[0054] It should be noted that the executing entity of the following method embodiments can be a closed area identification device for pipeline layout. This device can be implemented as part or all of the aforementioned computer equipment through software, hardware, or a combination of software and hardware. The following method embodiments are described using a computer equipment as the executing entity.

[0055] In one embodiment, such as Figure 2 As shown, a method for identifying closed regions in pipeline duct layout is provided, including the following steps:

[0056] Step 201: Obtain the building information model and draw the maximum outer contour line of the target floor in the building information model based on the building information model.

[0057] A building information model can include multiple model objects and the attribute information corresponding to each model object. Model objects can be walls, beams, columns, floors, etc. The attribute information corresponding to the model objects can include the type identifier of the model object, outline information, the set of edges of each face, etc.

[0058] Computer equipment can retrieve building information models (BIMs) from a database or from external storage devices. After retrieving the BIM, the computer equipment draws the maximum outer contour line of the target floor within the BIM.

[0059] In this embodiment of the application, the maximum outer contour line corresponding to the target floor can be the contour line of the maximum outer contour formed by the upper surface of the floor slab and the upper surface of the beam in the target floor.

[0060] For example, see Figure 3 , Figure 3 This is a schematic diagram of an exemplary maximum outer contour. Figure 3 The computer device determines the upper surface of the floor slab and the upper surface of the beam from the building information model, and then draws the maximum outer contour formed by the upper surface of the floor slab and the upper surface of the beam to obtain the maximum outer contour line.

[0061] In step 202, at least one closed entity is generated according to the maximum outer contour line and the building information model, and the closed entity is located in the maximum outer contour line.

[0062] The closed entity refers to an entity surrounded by a wall, for example, the closed entity can be a room.

[0063] Exemplarily, the computer device can open a new model, create a peripheral wall in the model according to the maximum outer contour line, then copy the walls and columns in the building information model into the peripheral wall, and then determine each minimum closed area surrounded by the wall, and generate a closed entity according to the minimum closed area.

[0064] In step 203, a line segment set of a bottom surface of the closed entity is obtained, and a maximum enclosing area surrounded by the line segments in the line segment set is taken as a closed area corresponding to the closed entity, and the closed area is used for pipeline comprehensive arrangement.

[0065] Exemplarily, after the closed entity is generated, the method Face.GetEdgesAsCurveLoops provided by the Revit software can be used to obtain the line segment set corresponding to the bottom surface of the closed entity.

[0066] The computer device calculates a maximum area surrounded by the line segments in each line segment set, and takes the maximum enclosing area surrounded by the line segments in each line segment set as a closed area.

[0067] Exemplarily, referring to Figure 4 , Figure 4 is a two-dimensional schematic diagram corresponding to a target floor and each closed area (for example, area 1, area 2, area 3 and area 4 shown in Figure 4 ) corresponding to the two-dimensional schematic diagram. In this way, the computer device automatically identifies the closed areas in the model.

[0068] Further, referring to Figure 5 , after step 203, the computer device can further perform steps 204, 205 and 206 shown in Figure 5 :

[0069] In step 204, each closed area is visually displayed.

[0070] In the embodiment of the application, after the computer device determines each closed area of the target floor, an association between each closed area and a corresponding area in the target floor in the model can be established. The corresponding area in the target floor can be identified by a spatial coordinate range, and each closed area is visually displayed.

[0071] At step 205, according to the selection instruction of the user for the target closed region, the target region corresponding to the target closed region in the building information model is searched in the preset mapping relationship.

[0072] If the computer device detects the selection instruction of the user for the target closed region, the target region corresponding to the target closed region in the model is searched in the mapping relationship established above.

[0073] At step 206, the target region is arranged in the pipeline synthesis.

[0074] The computer device arranges the target region in the pipeline synthesis, so as to realize the pipeline synthesis arrangement of the model.

[0075] In the embodiment of the application, the building information model should meet the requirements of the operable editing of the pipelines (water pipes, rectangular air pipes and bridge frames) and the pipeline synthesis arrangement of the structural members (beams, plates and columns) above. In this way, by obtaining the building information model, the maximum outer contour line of the target floor in the building information model is drawn according to the building information model, and then at least one closed entity is generated according to the maximum outer contour line and the building information model, the closed entity is located in the maximum outer contour line, then the line segment set of the bottom surface of the closed entity is obtained, and the maximum surrounding region surrounded by the line segments in the line segment set is taken as the closed region corresponding to the closed entity, and the closed region is used for the pipeline synthesis arrangement. In this way, each closed region in the target floor is accurately and quickly identified, so as to avoid the problems of low identification efficiency of the closed region and low creation efficiency of the building information model caused by the manual division of the closed region. The identification efficiency of the closed region is improved in the embodiment of the application, so as to improve the efficiency of the pipeline synthesis arrangement and the creation efficiency of the building information model.

[0076] In one embodiment, based on Figure 2 As shown in the embodiment, referring to Figure 6 The embodiment relates to the process in which the computer device identifies the maximum outer contour line of the target floor in the model. As shown in Figure 6 The process includes steps 601 and 602.

[0077] At step 601, the support body attribute data of at least one support body corresponding to the target floor is obtained according to the building information model.

[0078] In the embodiment of the application, the support body is the target floor or the target beam.

[0079] As described above, the building information model can include a plurality of model objects and attribute information corresponding to each model object, the model object can be a wall, a beam, a column, a floor, etc., and the attribute information corresponding to the model object can include a type identifier of the model object, contour information, a line segment set of each face, etc.

[0080] In this way, after the computer device obtains the building information model, the computer device can screen the type identifiers of the model objects in the attribute information, obtain the attribute information corresponding to the target floor and the attribute information corresponding to the target beam, and obtain the support body attribute data of the support body.

[0081] In step 602, the maximum outer contour line is calculated according to the support body attribute data of each support body.

[0082] In the embodiment of the present application, the support body attribute data of the support body includes a line set of each face of the support body, and each line set includes a set of all line segments corresponding to the face and a normal vector, and the normal vector is used to represent the direction of the face.

[0083] The computer device calculates the maximum outer contour line according to the line set of each face of each support body.

[0084] In one possible implementation of step 602, referring to Figure 7 , the computer device can perform steps 701 and 702 shown in Figure 7 to implement the process of step 602:

[0085] In step 701, the line set of the upper surface of the support body is determined from the support body attribute data.

[0086] As described above, the support body attribute data of the support body includes a line set of each face of the support body, and each line set includes a set of all line segments corresponding to the face and a normal vector. In this way, after the computer device obtains the line set of each face of a support body, for each line set, the computer device detects whether the normal vector in the line set represents that the direction of the face is vertically upward (for example, whether the normal vector is in the same direction as the Z-axis in the spatial coordinate system), and if so, it is determined that the face is the upper surface of the support body, thereby determining the line set of the upper surface of the support body.

[0087] In this way, the computer device obtains the line set of the upper surface of each support body.

[0088] In step 702, the maximum outer contour line is drawn according to the line set corresponding to each support body.

[0089] The computer device uses the maximum contour algorithm to calculate the set of maximum outer contour lines from the line set of the upper surface of each support body, and draws the maximum outer contour line.

[0090] The above embodiment can accurately draw the maximum outer contour line of the target floor through the line set of the upper surface of each support body in the target floor, and then identify the closed region based on the maximum outer contour line, thereby improving the identification accuracy of the closed region.

[0091] In one embodiment, based onFigure 2 As shown in the embodiments, refer to Figure 8 The embodiments relate to a process that how the computer device generates at least one closed entity according to the maximum outer contour line and the building information model. As shown in the embodiments, refer to Figure 8 As shown, step 202 can include Figure 8 As shown in the embodiments, refer to

[0092] Step 801, generating a peripheral wall body corresponding to the maximum outer contour line according to the maximum outer contour line.

[0093] Newly create a model, and call a wall body creation interface in the model to create a solid peripheral wall body for the maximum outer contour line.

[0094] Step 802, obtaining inner wall body attribute data and column attribute data corresponding to the target floor from the building information model, and generating a closed region according to the inner wall body attribute data and the column attribute data.

[0095] As described above, the building information model can include a plurality of model objects and attribute information corresponding to each model object, the model objects can be wall bodies, beams, columns, floors, etc., and the attribute information corresponding to the model objects can include type identifiers of the model objects, contour information, edge line sets of each face, etc.

[0096] In this way, after the computer device obtains the building information model, the computer device can filter the type identifiers of the model objects in the attribute information, obtain attribute information corresponding to wall bodies and attribute information corresponding to columns of the target floor, and obtain the inner wall body attribute data and the column attribute data.

[0097] Then, the computer device generates inner wall bodies and columns in the peripheral wall body according to the inner wall body attribute data and the column attribute data, and generates a closed region.

[0098] As shown in the embodiments, refer to Figure 9 , Figure 9 is a schematic view of a cross section of a closed region corresponding to a target floor.

[0099] In the embodiments of the present application, the inner wall body attribute data and the column attribute data are obtained from the building information model, and therefore, the positions of the inner wall bodies and the columns in the closed region are the same as the positions of the inner wall bodies and the columns in the building information model.

[0100] Step 803, determining at least one closed entity based on the closed region.

[0101] In one possible implementation of step 803, the computer device can perform steps A1-A3 as follows to implement the process of step 803:

[0102] Step A1, obtaining a list of minimum closed regions in the closed region.

[0103] The computer device can obtain the list of minimum closed regions that can generate rooms by using a method document.get_PlanTopology of the Revit software, and the list of minimum closed regions includes attribute information of each minimum closed region in the building information model.

[0104] In the embodiments of the present application, there is no wall in the minimum closed region, i.e., the standard for the computer device to identify the minimum closed region is that there is no wall in the region.

[0105] Step A2, generating a room entity corresponding to the minimum closed region in the peripheral wall according to the attribute information of the minimum closed region.

[0106] For the attribute information of each minimum closed region, the computer device calls a room creation interface to generate a room entity corresponding to the minimum closed region in the peripheral wall, i.e., to create a room for the minimum closed region.

[0107] Step A3, generating at least one closed entity according to each generated room entity.

[0108] For example, for each room entity, the computer device determines each candidate entity in the room entity and determines the area of each candidate entity, and the computer device takes the candidate entity with the largest area as the closed entity.

[0109] See Figure 10 , Figure 10 is a schematic cross-sectional view of an exemplary room entity. As can be seen from the schematic cross-sectional view, the candidate entities include a room entity and six column entities, and since the room entity has the largest volume, the room entity is taken as the closed entity.

[0110] After the computer device determines the closed entity, the computer device determines the bottom surface of the closed entity (the surface direction downward is the bottom surface), and the bottom surface of the closed entity is composed of the bottom surface of the room entity, the edge of the bottom surface, and the edge of the column, and then the computer device obtains a line segment set corresponding to the bottom surface of the closed entity.

[0111] The computer device calculates the largest region surrounded by the line segments in the line segment set, and takes the largest surrounded region as a closed region.

[0112] The computer device can create all closed regions corresponding to the target floor by using a method FilledRegion.Create of the Revit software and inputting the line segment set corresponding to the bottom surface of each closed entity.

[0113] In the above embodiment, the inner wall body attribute data and the column body attribute data are acquired from the building information model, and thus the positions of the inner wall bodies and the columns in the closed area are the same as the positions of the inner wall bodies and the columns in the building information model, so that the interference of other elements in the building information model can be reduced, and the recognition efficiency of the closed area is improved, and thus the efficiency of the pipe arrangement and the efficiency of the creation of the building information model are improved.

Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other orders.
