Referring to fig. 1 in detail, fig. 1 is a schematic flow chart of an th embodiment of a building information model splicing method according to the present invention, and the building information model splicing method of the present embodiment includes the following steps.
S11, obtaining model information of th building information models, wherein the th building information model comprises a plurality of members, and the th model information comprises basic information of the members and spatial information of the members in the th building information model.
The member is a basic constituent unit of the building information model, i.e., a basic constituent unit of the BIM model, and a plurality of members may constitute the building information model.
th model information of a plurality of th building information models is acquired, the th building information model includes a plurality of members, and the th model information includes basic information of the plurality of members and spatial information of the plurality of members in the th building information model.
The basic information of the member specifically comprises basic information such as name, size and construction cost, the spatial information of the member in the th building information model, namely the specific three-dimensional coordinate of the member in the th building information model, and the only position of the member in the th building information model can be determined through the basic information and the spatial information of the member.
In a specific scenario, the BIM software may obtain th model information locally, or obtain th model information from a server.
In a specific scenario, for example, the building information model may be a room unit, and the member may be a related wall, or a window sill.
After the th building information model is designed by a plurality of terminals, the th building information model is split and analyzed, th model information is extracted, compared with the th building information model, the th model information is based on the information of the member, therefore, the member is easy to be independently modified and compared, then, the th model information which is respectively designed can be sent to the server by the plurality of terminals, so that the server stores a plurality of th model information, and when the design is needed, the terminals can obtain the needed th model information from the server.
And S12, acquiring the splicing rule.
The splicing rule comprises spatial information of a plurality of th building information models in a second building information model to be spliced.
And S13, processing the th model information by adopting a splicing rule to generate a second building information model, wherein the second building information model is formed by splicing a plurality of th building information models.
The th model information is processed using stitching rules to generate a second building information model.
Referring to fig. 2, fig. 2 shows the substep of step S13 in the -th embodiment of the building information model splicing method of the present invention, which comprises the following steps:
s131, correspondingly generating a plurality of th building information models according to the plurality of th model information.
Since the th model information includes basic information of a plurality of construction elements and spatial information of the plurality of construction elements in the th building information model, and the construction elements serve as basic constituent units of the th building information model, a corresponding th building information model can be generated from the th model information.
Specifically, the th building information model may be a room unit, and the members of the room unit may be related walls, , or windowsills, etc. the th model information includes basic information and spatial positions of the members of the room unit, and thus the room unit may be correspondingly generated according to the th model information.
And S132, arranging a plurality of th building information models at corresponding spatial positions according to the splicing rule to obtain a third building information model.
After the th building information model is obtained, since the splicing rule includes spatial information of the th building information model in the second building information model to be spliced, namely three-dimensional coordinate information of the th building information model in the second building information model to be spliced, a plurality of th building information models can be arranged at corresponding spatial positions according to the splicing rule to obtain a third building information model, namely, the th building information model is arranged at a spatial position corresponding to the three-dimensional coordinate information, so that the third building information model is obtained.
It should be noted that, in the embodiment, the third building information model is obtained only by setting the corresponding spatial position of the th building information model, and the th building information model in the third building information model may need to be modified, replaced, or adjusted, etc. to obtain the final second building information model.
In other embodiments, the third building information model may also be directly used as the second building information model, mainly for a specific scenario.
In a specific embodiment, the th building information model may be a room unit, and the second building information model may be a house unit, the house unit, such as a triple or double living room, is composed of a plurality of room units, so that at the time of design, the terminal may obtain the th building information model of a desired room unit from the server, generate a corresponding room unit based on the th building information model, then determine three-dimensional coordinate information of each room unit, and set each room unit on the corresponding three-dimensional coordinate information.

And S133, deleting the repeated components in the third building information model according to the splicing rule and the th model information to obtain a second building information model.
In a specific embodiment, when the th building information model is spliced, member duplication may occur, that is, two identical members are present at the same position .
In the case of multiple room units spliced into a dwelling unit, it may happen that adjacent room units share the same wall, and repetition occurs at this wall member.
As in a certain dwelling unit, the galley room unit is adjacent to the lavatory room unit, and in a particular design product, the walls between the galley room unit and the lavatory room unit should be shared, but during the splicing process, the galley room unit and the lavatory room unit both include the same members, so that the two -th building information models are duplicated, and the duplicated members need to be deleted so that only duplicated members remain, thereby obtaining the second building information model.
Referring to fig. 3, fig. 3 is a sub-step of step S133 in fig. 2 in the building information model splicing method according to the present invention; the method comprises the following specific steps:
and S1331, determining the spatial information of the member in the third building information model according to the splicing rule and the th model information.
The th model information includes spatial information of the component in the th building information model, and the splicing rule determines spatial information of the th building information model in the third building information model, so that the spatial information of the component in the third building information model can be further steps with the th model information according to the splicing rule.
Specifically, the spatial information a (x1, y1, z1) of the component in the th building information model, the spatial information B (x2, y2, z2) of the th building information model in the third building information model, for example, may be added to the spatial information a to obtain the spatial information C (x1+ x2, y1+ y2, z1+ z2) of the component in the third building information model.
S1332, at least two members of the third building information model where the spatial information overlaps are determined.
After the spatial information of the members in the plurality of th building information models is determined, the spatial information of the members is first compared to determine whether there are at least two members where the spatial information overlaps.
In the present embodiment, the spatial information mentioned above overlaps, and cases may represent that the spatial information of two members is the same, in another case, a part of the same may occur, specifically, the members are three-dimensional structures with a size of , and the spatial information exists in a certain area range, for example, a wall m of a room unit a is a whole range of possible spatial information D { (20, 30, 50) - (40, 80, 100) }, if the spatial information E { (25, 60, 60) - (40, 70, 80) } of a wall n of another adjacent room unit b, it is obvious that the spatial information of the wall m of the spatial information D overlaps with the spatial information of a wall n corresponding to the spatial information E, and thus it is determined that the wall n and the wall n are overlapped members.
In a specific embodiment, the third building information model may be filtered based on the names in the basic information, -like members may be filtered, and spatial information may be compared for the members, so as to reduce the amount of computation.
S1333, deleting the overlapped part of the spatial information in at least two members.

In a specific embodiment, the spatial information of two components may be overlapped, or the spatial information of three or more components may be overlapped, which is not limited herein.
It should be noted that, in a specific embodiment, the deletion in this step may completely delete the overlapped part of the spatial information in the two components, and mark the deleted part, or hide the deleted part, so as to ensure that when the th building information model in the second building information model needs to be extracted later, the deleted part of the component can still extract information, so as to ensure the integrity of the entire th building information model.
For example, the wall m of the room unit a overlaps with the spatial information of the wall n of the room unit b, and from the comparison between the spatial information E and the spatial information D, the wall n of the room unit b is parts of the wall m of the room unit a, so that the wall n of the whole room unit b needs to be deleted and repeated, but the spatial information { (25, 60, 60) - (40, 70, 80) }, i.e. the corresponding part of the spatial information E of the original wall n, may be marked on the wall m of the room unit a, so that when the room unit b in the second building information model is extracted, the information of the wall n can still be ensured to be extracted.
In the above embodiment, the second building information model is obtained by obtaining model information and splicing rules of multiple -th building information models, generating corresponding -th building information models according to model information, correspondingly setting -th building information models according to the splicing rules, thus obtaining a third building information model, and finally performing deduplication processing on members in the third building information model based on the splicing rules and -th model information.
In addition, in the aspect, the invention is based on the model information rather than the building information model, compared with the method of directly splicing through the building information model, because the building information model is based on the whole model and the building information model is entity models, although the method has good visualization function, data comparison between the models cannot be carried out, and the model information is based on the members in the model, the data comparison of the members in the model is convenient, and the members can be directly modified and searched, therefore, after the invention splices and obtains the second building information model based on the model information, the aspect can automatically delete and re-weight the members according to the spatial information of the members, and the aspect can modify the members in the field better without changing the whole model.

Specifically, the th model information may be modified based on the modification information, and the th building information model may be generated in the third building information model again.
Specifically, compared with splicing directly through the th building information model, the method is based on the splicing of the th model information, so that the member layer can be directly modified without modifying the th building information model integrally, and the modification is relatively convenient.
In other embodiments, th building information model in the second building information model may be modified, and is not limited herein.
