[0002] In recent years, Building Information Modeling (BIM) technology has been introduced in the construction industry. It uses BIM modeling software to construct three-dimensional building models, including geometric and non-geometric information about all building components and equipment, as well as the relationships between them. This model information covers the entire lifecycle of building design, construction, and operation and maintenance, and this information continues to deepen and increase as the construction phase progresses. Construction, design, construction, operations, and consulting units use a range of application software to design and construct using a unified building information model, enabling collaborative project management, reducing errors, saving costs, and improving quality and efficiency. After the project is completed, the three-dimensional building model is used to implement building operations management and improve operational efficiency. A Geographic Information System (GIS) is a spatial information system that, supported by computer software and hardware systems, collects, stores, manages, calculates, analyzes, displays, and describes geographic distribution data on the entire or partial Earth's surface (including the atmosphere).

[0045] In order to promote information, the present application provides a digital twin-based display data processing method, computing device, and storage medium to achieve effective integration of GIS and BIM based on process display data.

[0046] The following further describes the digital twin-based display data processing method provided in the embodiment of the present application with reference to the accompanying drawings.

[0047] like Figure 1 , which is a flowchart of the data processing method based on digital twins, including the following steps:

[0048] S11: Obtain the BIM model data of the target building object, refer to Figure 1a , as an example diagram.

[0049] S12: Encode the BIM model data according to a preset algorithm to obtain BIM encoded data, where the encoded data at least includes an encoding attribute field;

[0050] S13: Preprocessing the loaded GIS model data corresponding to the target building object to obtain GIS preprocessed data;

[0051] S14: Matching the BIM coded data with the GIS pre-processed data;

[0052] S15: After mapping the matching result to the coding attribute field, a new BIM model of the target building object is loaded to obtain fusion display data.

[0053] This implementation enables displaying multi-source heterogeneous data on a "single map" during the loading process.

[0054] refer to Figure 2 , encoding the BIM model data according to a preset algorithm, which is specifically implemented as follows:

[0055] S21: parsing the unit structure data of the target building object and obtaining coordinates in the unit structure data;

[0056] S22: superimposing preset values ​​of a BIM model matching the building unit with the building unit coordinates to generate superimposed data;

[0057] Preferably, the preset values ​​of the BIM model matched by the building unit are specifically:

[0058] The building unit matches 1 / 2 model height of the BIM model.

[0059] S23: Add a time stamp to the superimposed data to form a unique code for the unit structure.

[0060] For example, the BIM model code generation rule is to generate the code by combining the unit building's 2D coordinates + 1 / 2 the model's height + a timestamp, thereby unifying the data standards, formats, and temporal information between the two models. The above code generation process is explained in this specification as an example and is not limited to this form.

[0061] refer to Figure 3 , pre-processing the loaded GIS model data corresponding to the target building object, including:

[0062] S31: Loading GIS model data corresponding to the target building object;

[0063] Preferably, GIS model data is implemented by creating a workspace;

[0064] S32: extracting the data to be singulated from the GIS model data, and creating a new data set within the scope of the data to be singulated;

[0065] Optionally, extracting the data to be singulated from the GIS model data is specifically implemented by extracting a data source of the GIS model data, where the data source is used to store surface data; that is, creating a new data source for storing surface data.

[0066] S33: After processing the newly created data set according to the coded attribute field, the data to be singulated is mapped using a GIS model to obtain GIS pre-processed data.

[0067] The newly created dataset is processed, and optionally, the attribute structure is modified in the dataset created in step S32, and a BIM model encoding attribute field is added to facilitate subsequent selection of the newly created dataset in step S32 and drawing of unit buildings using GIS model data.

[0068] The tool for preprocessing the loaded GIS model data corresponding to the target building object is SuperMap, but is not limited thereto.

[0069] refer to Figure 4 and 4a After mapping the matching result to the coded attribute field and before loading the new BIM model of the target building object, the method further includes:

[0070] S411: Determine whether the matching result is correct through a loop;

[0071] S412: When the matching result is correct, determine whether the mapping to the encoding attribute field is successful;

[0072] Figure 3 The completed step is the singulation step of the GIS model. That is, after completing the steps of the embodiment of step 13, the singulated GIS model and the BIM model code are automatically matched. The matched value is automatically mapped to the model code attribute field created in step 412.

[0073] S413: When the mapping is successful, the new BIM model of the target building object is loaded.

[0074] Preferably, loading a new BIM model of the target building object comprises:

[0075] The new BIM model is loaded according to the progress of mapping the matching results to the coded attribute fields.

[0076] refer to Figure 4 After the 3D model is loaded to a certain level, right-click. If it matches the BIM model, there will be a button to enter the model. Click "Enter Model" to directly open the BIM model and display it on a picture.
