At present, when Building Information Model (BIM) is built, a BIM model which is initially built on line needs to be checked, modified and corrected to obtain a final BIM model, and the model is usually modified in a mode that the model is downloaded from an on-line platform to be manually adjusted, and then the modified and adjusted model is uploaded again, so that the work efficiency of BIM modeling workers can be influenced by the on-line and off-line reciprocating.

In view of the foregoing problems, embodiments of the present application provide a model processing method and a related apparatus, and the following describes embodiments of the present application in detail with reference to the accompanying drawings.

As shown in fig. 1, fig. 1 is an architecture diagram of a model processing system provided in an embodiment of the present application, where the model processing system 100 includes: a terminal device 101 and a model processing platform 102, the terminal device 101 and the model processing platform 102 being communicatively coupled. A user can send a building structure drawing to the model processing platform 102 through the terminal device 101, after receiving the building structure drawing, the model processing platform can identify the building structure drawing and generate a corresponding initial BIM model, and then when receiving a modification instruction sent by the user through the terminal device 101, the model processing platform can modify the initial BIM model according to the modification instruction to obtain a modified BIM model, and store the modified BIM model as a file format that can be opened by BIM modeling software, wherein the modification of the BIM model can be realized based on a related function in an unral 4 engine (a UE4 image engine described later).

Referring to fig. 2, fig. 2 is a schematic flow chart of a model processing method according to an embodiment of the present application, where the method according to the embodiment of the present application can be applied to the model processing platform shown in fig. 1, and as shown in the figure, the model processing method includes the following operations:

s201, receiving an architectural structure drawing uploaded by a terminal device, and identifying a plurality of reference components in the architectural structure drawing;

wherein the architectural structure drawing includes a construction drawing created using engineering drawing software, such as auto CAD drawing software.

In the concrete implementation, a plurality of reference members in the building structure drawing are identified, and the reference members in the building structure drawing can be identified by identifying information such as layers, figures, characters and the like in the building structure drawing. For example, the components in the CAD drawing are determined by identifying the components of each layer in the CAD drawing, or the components are determined by the component description information in the CAD drawing, or the lines in the CAD drawing are directly identified, for example, the lines are sent to a pre-stored component prediction model for processing, and then the components in the CAD drawing are identified.

S202, determining a target component corresponding to each reference component in the plurality of reference components in a Building Information Model (BIM) component library according to preset rules, and generating a first BIM according to the target component corresponding to each reference component in the plurality of reference components;

the BIM component library can be a component library supported by BIM model modeling software, and the BIM modeling software comprises REVIT software.

Because the components required for building the BIM model need to be determined according to the components in the architectural structure drawing, the corresponding relationship between each component in the structural drawing and the BIM model component needs to be determined, and the preset rule is used for determining the corresponding relationship. In the concrete implementation, the corresponding relation can be established according to the names of the members in the building structure drawing and the names of the members in the BIM member library, the corresponding relation can also be established according to the shapes of the members in the building structure drawing and the shapes of the members in the BIM member library, or the corresponding relation can also be determined through other rules, then the members in the BIM model corresponding to the building structure drawing can be determined according to the corresponding relation, the corresponding BIM model is generated through identifying the building structure drawing, and manual modeling is not needed.

S203, receiving a modification instruction, and modifying the first BIM model based on the modification instruction to obtain a second BIM model;

and S204, saving the second BIM model in a preset format to obtain a BIM model file, wherein the preset format is a file format supported by BIM modeling software.

The file formats supported by the BIM modeling software comprise an FBX file and an RVT file.

In a specific implementation, in steps S203 and S204, the modification of the BIM model may include movement, increase, decrease, modification of model attribute parameters, and the like of components in the model, and the modification of the model may be applied to, for example: after a BIM model is established preliminarily by identifying a building structure drawing, checking and modifying the preliminary model to obtain a final BIM model corresponding to the building structure drawing; or after the BIM model is generated and modified, modifying the model when other requirements for adjusting the model exist, such as equipment facility changes caused by room function changes in the property management process.

For example, after a user uploads a building structure drawing to a platform through terminal equipment, the platform receives the building structure drawing and generates a BIM model, the BIM model may be modified through a UE4 image engine, for example, when a member movement instruction for the BIM model is received, the BIM model may be modified through a member movement function in a UE4 image engine, so as to obtain a modified model. The UE4 image engine may save the modified BIM model in FBX format, which may be opened again with the REVIT software.

It can be seen that, in the embodiment of the present application, an architectural structure drawing uploaded by a terminal device is received, a plurality of reference members in the architectural structure drawing are identified, a target member in a BIM member library corresponding to each reference member in the plurality of reference members is determined according to a preset rule, a first BIM model is generated according to the target member corresponding to each reference member in the plurality of reference members, then, when a modification instruction is received, the first BIM model is modified based on the modification instruction to obtain a second BIM model, and finally, the second BIM model is saved in a preset format to obtain a BIM model file, where the preset format is a file format supported by BIM modeling software. Therefore, the generation and modification of the BIM model are carried out on line, and then the modified BIM model is stored in a file format supported by BIM modeling software, namely, the on-line generated model or the modification of the model is stored in a file which can be opened by the BIM modeling software. The model needing to be modified does not need to be downloaded first, and the model is uploaded again after being modified offline, so that the generation and modification processes of the BIM model are simplified, and the modeling efficiency of the BIM model is improved.

In one possible example, the modifying instruction includes an identification of a component to be modified, a modification action type, and modification location information, and the modifying the first BIM model based on the modifying instruction to obtain a second BIM model includes: determining a component corresponding to the identifier of the component to be modified from the BIM component library according to the identifier of the component to be modified; determining a position to be modified in the first BIM according to the modified position information; when the modification action is increasing, adding a member corresponding to the member identifier to be modified at the position to be modified in the first BIM model to obtain a second BIM model; and when the modification is deleted, deleting the component at the position to be modified in the first BIM model in the component corresponding to the identifier of the component to be modified so as to obtain the second BIM model.

When modification in the modification instruction is increased, the component corresponding to the modification instruction in the BIM component library can be determined according to the identifier of the component to be modified, and then the component is added to the position to be modified in the BIM model determined according to the modification position information to complete modification. When the modification instruction is deletion, since the components in the component library may be used for multiple times when one BIM model is established, there may be multiple components with the same component identifier in one BIM model, and there may be multiple components determined by the component identifier to be modified, so that the component to be deleted in the component corresponding to the component identifier to be modified is determined by modifying the position information, and the modified BIM model is obtained by deleting the component to be deleted.

Therefore, in this example, the modification instruction includes the identifier of the component to be modified, the modification action type, and the modification position information, and when the BIM model is modified, the component to be modified and the position to be modified can be accurately determined through the information, and the BIM model is modified, which is beneficial to improving the accuracy of the modification of the BIM model.

In one possible example, the modifying instruction includes an identifier of a component to be modified, position information before movement, and position information after movement, and modifying the first BIM model based on the modifying instruction to obtain a second BIM model includes: determining a component corresponding to the identifier of the component to be modified from the BIM component library according to the identifier of the component to be modified; determining a component to be moved from the components corresponding to the component identification to be modified according to the position information before movement; and moving the member to be moved to the position indicated by the moved position information to obtain the second BIM model.

In the concrete implementation, different component identifiers correspond to different components in the BIM component library one to one, the component identifiers are not changed when the components in the BIM component library are used for building a BIM model, and the components in the BIM model can be used for multiple times when one BIM model is built, so that multiple components with the same component identifiers can be in one BIM model, when the components are moved, the components can be determined according to the component identifiers to be modified, the components to be moved need to be determined according to the position information before the movement, then the components to be moved are moved to the position indicated by the position information after the movement, and the modification of the BIM model is completed to obtain the modified BIM model.

It can be seen that, in this example, the modification instruction includes a modification component identifier, position information before movement, and position information after movement, a component corresponding to the modification component identifier is determined through the to-be-modified component identifier, a component to be moved is determined through the position information before movement, and finally the component to be moved is moved to a position indicated by the position information after movement.

In one possible example, the modifying instruction includes an identifier of a component to be modified, an identifier of a parameter to be modified, and a parameter value, and the modifying the first BIM model based on the modifying instruction to obtain a second BIM model includes: determining the component to be modified in the first BIM according to the identifier of the component to be modified; determining the parameters to be modified in the members to be modified according to the parameter identifications to be modified; modifying the value of the parameter to be modified in the component to be modified into the parameter value to obtain the second BIM model; or adjusting the parameter to be modified in the component to be modified according to the parameter value to obtain the second BIM.

The value of the parameter to be modified in the component to be modified is modified into a parameter value, that is, the user can directly set the value of the parameter to be modified to a specific value according to the requirement. The parameter value may be used as a step length when the parameter value of the parameter to be modified is adjusted according to the parameter value, for example, the parameter value is 2, the original parameter value of the parameter to be modified is 5, the original parameter value of the parameter to be modified may be adjusted by using 2 as the step length, for example, 5 is reduced to 3 or reduced to 1, or 5 is increased to 7 or increased to 9, or the parameter value is adjusted by fixing the value 2 each time, and the value of each increase or decrease of the parameter value is 2 when the parameter value is adjusted. Or the parameter value of the parameter to be modified may be adjusted according to the multiple of the parameter value, for example, the parameter value is 3, the original parameter value of the parameter to be modified is 6, and the parameter value of the parameter to be modified may be adjusted to 3 times, that is, after the parameter to be modified is adjusted according to the parameter value, the parameter value of the parameter to be modified is 18.

It can be seen that, in this example, the modification instruction includes the identifier of the component to be modified, the identifier of the parameter to be modified, and the parameter value, and the parameter to be modified of the component to be modified in the BIM model can be determined through the identifier of the component to be modified and the identifier of the parameter to be modified, and the value of the parameter to be modified in the component to be modified is modified to the parameter value, or the parameter to be modified in the component to be modified is adjusted according to the parameter value, which is beneficial to improving the flexibility of modification of the BIM model.

In one possible example, the determining, according to preset rules, a target member corresponding to each of the plurality of reference members in the building information model BIM member library, and generating a first BIM model according to the target member corresponding to each of the plurality of reference members includes: determining a component group corresponding to any reference component P in the plurality of reference components from the BIM component library, wherein the component group comprises M matching components, and M is an integer greater than 0; matching the reference component P with each matching component in the component group corresponding to the reference component P to obtain M matching values, wherein the M matching components are in one-to-one correspondence with the M matching values; determining a matching component corresponding to a matching value Q as a target component corresponding to the reference component P, wherein the matching value Q is the maximum value of the M matching values; generating the first BIM model from a target component corresponding to each of the plurality of reference components.

In a specific implementation, when the component group corresponding to the reference component is determined, the component group corresponding to the reference component may be determined through the component description information in the building structure drawing, for example, if the component belongs to the window component through the component description information, the window component group in the BIM component library may be determined, and then the reference component is matched with each component in the window component group, and the matching component with the largest matching value is determined to be the matching component corresponding to the reference component.

As can be seen, in this example, for each reference member in the building structure drawing, the reference member is matched with each matching member in the corresponding member group in the BIM member library to obtain a plurality of matching values, the matching member corresponding to the largest matching value is determined as the target member corresponding to the reference member, and then the BIM model corresponding to the building structure drawing is generated according to the plurality of target members corresponding to the plurality of reference members, which is beneficial to improving the accuracy of determining the members when the BIM model is generated, and further improving the accuracy of generating the BIM model by identifying the building structure drawing.

In one possible example, the BIM model file further includes modification trace information, and the modification trace information includes at least one of the following: modifying trace, modifying operator identity information and modifying time.

In the specific implementation, after the BIM model is modified each time, modification trace information is also stored in the BIM model file storing the modified BIM model, where the modification trace information may include modification traces corresponding to modification operations, identity information of a modification operator, and modification time, and when the BIM model file is opened again by software such as REVIT, modification contrast may be displayed, modification traces of different users, that is, modification operators, may also be displayed, and modification time corresponding to modification of each modification trace may also be displayed.

It can be seen that, in this example, the BIM model file further includes modification trace information, where the modification trace information includes at least one of the following: the method comprises the steps of modifying the trace, modifying the identity information of an operator and modifying time, wherein a user opens a BIM model file containing the information of the modifying trace, can display the content related to the modifying trace of the BIM model, and is favorable for improving the user experience.

In one possible example, before modifying the first BIM model based on the modification instruction to obtain the second BIM model, the method further includes: detecting whether a modification operator has the authority of calling the modification instruction; and if the authority of calling the modification instruction is possessed, modifying the first BIM model based on the modification instruction to obtain the second BIM model.

In the specific implementation, in consideration of the security problem, after the modification instruction is received, the BIM model is not modified directly according to the modification instruction, but the permission of the modification operator is detected before modification, and the modification operator has the permission to call a certain modification instruction, so that the BIM model can be modified based on the modification instruction. Furthermore, different permission levels can be set, the different permission levels correspond to different modification instructions, and when the permission with a certain level is detected, the modification instruction corresponding to the permission level and the modification instruction corresponding to the permission lower than the permission level can be called to modify the BIM.

In addition, modification rights corresponding to different members can be set, and when the modification rights of the members are detected, the members can be modified, for example, for important members forming a bearing wall in a BIM model, the members can be modified when the modification rights of the members are detected.

Therefore, in this example, before the BIM model is modified based on the modification instruction, it is detected whether the operator has the authority to call the modification instruction, and if so, the BIM model is modified based on the modification instruction, which is beneficial to ensuring the safety of the modification of the BIM model.

In one possible example, the modifying instruction includes a modifying instruction, and modifying the first BIM model based on the modifying instruction to obtain a second BIM model includes: and checking and modifying the first BIM model according to the checking and modifying instruction and a preset checking and modifying rule to obtain the second BIM model, wherein the preset checking and modifying rule is determined according to original BIM model sample data, the modifying instruction and the corresponding checked and modified BIM model sample data.

In the specific implementation, when building information modeling is performed on line, for a building information model preliminarily generated according to the identification result of the building structure drawing, because some errors exist between the building information model and the model represented by the building structure drawing, the building information model is required to be checked, modified and corrected to obtain a final building information model. After a plurality of times of model checking and modifying are carried out and a large amount of relevant data of model checking and modifying are collected, the checking and modifying rule of model checking and modifying can be determined based on the data, and when the model is checked and modified, the platform can automatically check and modify the model based on the checking and modifying rule.

Therefore, in the example, the modification instruction comprises a modification checking instruction, and after the modification checking instruction is received, the BIM model is checked and modified through the preset modification checking rule, so that manual modification checking of the BIM model is not needed, and the BIM modeling efficiency is improved.

In one possible example, after the modifying the first BIM model based on the modifying instruction to obtain the second BIM model, the method further includes: and modifying the preset modification rule by taking the first BIM model, the modification command and the second BIM model as sample data.

In specific implementation, after the first BIM model is checked and modified to obtain the second BIM model, the first BIM model, the checking and modifying instruction and the second BIM model can be also used as sample data, sample data is enriched, and the checking and modifying rule is modified based on the updated sample data.

In this example, the first BIM model, the modification searching instruction and the second BIM model are used as sample data, the preset modification searching rule is modified, the sample data for determining the modification searching rule is enriched, the modification searching rule is updated, and accuracy of a modification searching result of model modification searching according to the modification searching rule is facilitated.

In one possible example, the modifying instruction includes an identification of a component to be modified and a modification action type, and modifying the first BIM model based on the modifying instruction to obtain a second BIM model includes: determining a component corresponding to the identifier of the component to be modified from the BIM component library according to the identifier of the component to be modified; and when the modification is deletion, deleting the component corresponding to the identifier of the component to be modified in the first BIM to obtain the second BIM.

In the concrete implementation, different component identifiers correspond to different components in the BIM component library one to one, the component identifiers are not changed when the components in the BIM component library are used for building a BIM model, because one component in the BIM component library can be used for multiple times when the BIM model is built, a plurality of corresponding components in the BIM model have the same component identifiers, when the components are processed, a plurality of components to be modified can be determined according to the component identifiers, and then the components are processed in batches, for example, a plurality of components corresponding to the identifiers are deleted.

Therefore, in this example, the corresponding component is determined by modifying the identifier of the component to be modified in the instruction, and when the modification action is deletion, the component corresponding to the identifier to be modified in the BIM model is deleted, so that batch processing of the components in the BIM model can be realized, and the efficiency of modifying the BIM model can be improved.

In one possible example, the modifying instruction includes an identifier of a component to be modified and location information after the movement, and modifying the first BIM model based on the modifying instruction to obtain a second BIM model includes: determining a component corresponding to the identifier of the component to be modified from the BIM component library according to the identifier of the component to be modified; and moving the member corresponding to the member identification to be modified to the position indicated by the moved position information to obtain the second BIM.

In the specific implementation, the same as the above example, different component identifiers correspond to different components in the component library one to one, and when the first BIM model is built, the component identifiers of the components are not changed, and one component in the BIM component library may be used multiple times, so that a plurality of components with the same component identifier in the first BIM model can be determined according to the component identifier to be modified, and further, the plurality of components can be determined at one time. When the component corresponding to the identifier of the component to be modified is moved to the position indicated by the moved position information, if there are a plurality of components, one moving base point may be determined first, the moving base point is moved to the specific position indicated by the moved position information, and the specific position of each component is determined according to the relative position relationship between the moving base point and each component.

In this example, the component corresponding to the identifier of the component to be modified is determined according to the identifier of the component to be modified, and then the component corresponding to the identifier of the component to be modified is moved to the position indicated by the moved position information to obtain the second BIM model.
