It not only improves the efficiency of design work, but also provides users with a more intuitive and immersive experience. By combining two-dimensional and three-dimensional design results and using virtual reality and other means, virtual construction technology provides better support for the multimodal display of design results. Virtual construction technology, usually combined with building information modeling (BIM) technology, is a revolutionary advancement in the design and creative industries. It provides a new way of design, analysis and communication by creating and simulating three-dimensional digital models of buildings or engineering projects. Traditional design mainly relies on two-dimensional drawings, which have limitations in expressing complex structures and spatial relationships, and are difficult for non-professionals to understand.

[0003] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide an iterative derivation method for multimodal design results based on virtual construction, so as to realize the gradual iteration and optimization from two-dimensional design drawings to six-dimensional information models.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A multi-modal design result iterative derivation method based on virtual construction, comprising the following steps: Step 1: Standardize and modularize the design results; the design results include drawings and BIM models involved in the design planning stage, preliminary design stage, detailed design stage and in-depth design stage; the standardization refers to the scale, line type and line width, symbols and legends, material annotations, annotations and instructions of the two-dimensional and three-dimensional design results following unified regulations; the modularization refers to the two-dimensional and three-dimensional design results, which establish one-to-one corresponding modules through slicing, realize the addition of two-dimensional to six-dimensional information through modules, and establish the iterative evolution relationship between six-dimensional and three-dimensional design results through modules; Step 2: Establish a virtual construction environment, and establish corresponding virtual scenes according to the modularized design results; the virtual construction environment is an integrated space including all virtual module scenes; Step 3: Import the two-dimensional and three-dimensional preliminary design results into the virtual construction environment; the two-dimensional preliminary design results are design drawings; the three-dimensional preliminary design results are BIM models corresponding to the design drawings; the two-dimensional and three-dimensional design results are imported into the corresponding virtual scenes according to the modules, and the scheme simulation is carried out; Step 4: Iteratively derive preliminary design results based on simulation results to form detailed design results; the detailed design results add time dimension information, import the corresponding four-dimensional virtual scenes according to modules, and perform construction progress simulation; Step 5: Iterate the detailed design results according to the simulation results to form in-depth design results; the in-depth design results add cost dimension information, import the corresponding five-dimensional virtual scenes according to the modules, and perform material and construction process simulation; Step 6: Iteratively derive in-depth design results based on simulation results; the in-depth design results add environmental and safety dimension information, import the corresponding six-dimensional virtual scenes according to modules, and simulate the planning of temporary facilities on the construction site; the six-dimensional virtual scenes integrate GIS model data; Step 7: Integrate all modular virtual scenes established in step 6 to simulate the overall design plan, construction progress, materials and construction process, and temporary facilities planning at the construction site; the simulation is a multi-modal design result cycle simulation; the design result is a two-dimensional or three-dimensional design result that is iterated cyclically based on the simulation results.

[0006] Further: The standardization and modularization of the design results in step 1 are specifically achieved through the following steps: Step 1.1: Establish a unified coding standard: Ensure that 2D drawings and 3D models use the same coding and naming rules for easy identification and association; Step 1.2: Establish a unified data dictionary: ensure that the data expressions in the two-dimensional drawings, three-dimensional models, construction processes, and construction scheme design results have the same meaning, so as to facilitate the association and iteration of two-dimensional to six-dimensional scene modules; Step 1.3: Use the modular function of BIM software to create reusable modular units based on 2D drawings, and reversely associate and generate corresponding 2D drawings; Step 1.4: Parameterize and informatize the module unit components to realize the linkage update of all views and drawings when modifying a single component; Step 1.5: 2D and 3D module linkage. Synchronous management of 2D plane module information and 3D space module information is performed in the virtual construction system. Through the 2D and 3D linkage method, the 2D and 3D module linkage visualization display is realized. For example, clicking on the 2D drawing module can locate the module corresponding to the 3D model and highlight it, and vice versa.

Through the cross-scene association of two-dimensional and three-dimensional modules in virtual scenes, the linkage of two-dimensional and three-dimensional modules in each virtual scene is realized. For example, when the three-dimensional model in sub-scene one changes, the corresponding modules involving the three-dimensional model in other scenes change synchronously.

[0008] Further: Steps 3, 4, 5, and 6 are specifically implemented by the following steps: Step 3.1: Import the 2D and 3D design results of each stage by module; Step 3.2: Each module imports the virtual scene linkage; Step 3.3: Simulation of each module scenario; Step 3.4: Improve the 3D design results based on the simulation results; Step 3.5: Generate, export, improve and divide the two-dimensional design results into modules; Step 3.6: Repeat steps 3.1-3.5 until the next stage of two-dimensional and three-dimensional design results are formed.

[0009] Further: Step 7 is specifically implemented by the following steps: Step 7.1: Import the final 2D and 3D design results formed in step 6; Step 7.2: In the integrated virtual construction scene, the overall plan of the design results, construction progress, material and construction process simulation, and temporary facilities planning simulation at the construction site are carried out in sequence; Step 7.3: Make local adjustments based on the simulation results, locate the corresponding scene module, and repeat steps 3.3 and 3.4; Step 7.4: Improve and export the 3D design results; Step 7.5: Repeat steps 7.1-7.4 until the plan, construction progress, material and construction process simulation, and construction site temporary facilities planning simulation results are passed.

[0010] By adopting the above technical solution, the present invention has the following beneficial effects: The multimodal design results iterative derivation method based on virtual construction of the present invention not only improves the efficiency of design work, but also enhances the participation of owners and other stakeholders by providing a more intuitive and immersive experience, thereby playing an important role in the design and creative industries.
