[0032] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0033] like Figure 1 As shown, the embodiment of the present invention discloses a digital accurate model matching method based on BIM technology, and the method comprises the following steps:

[0034] Capturing a three-dimensional high-definition image of the interior of the construction scene, and converting the three-dimensional high-definition image into a BIM model;

[0035] Receiving mold matching requirement data, processing the mold matching requirement data using a large language model, and extracting a mold matching parameter set;

[0036] The BIM model is processed by using the mold matching parameter set and the mold matching standard library to obtain a mold matching project file.

[0037] The construction designer takes a three-dimensional high-definition image of the interior of the construction scene in advance, and uses conversion software to extract and convert the three-dimensional features of each detailed structure in the three-dimensional high-definition image to obtain a BIM model, which is the three-dimensional structural data of each object to be constructed inside the construction scene. Then, the large language model is used to process the mold matching demand data output by the designer to extract the mold matching parameters, and the mold matching parameters are grouped and summarized to form a mold matching parameter set. Finally, the BIM model obtained above is processed under the constraints of the mold matching parameter set to achieve mold matching, that is, to match the material model of the corresponding material and corresponding size parameters for each detailed structure inside the construction scene. The obtained mold matching project file can be subsequently transferred to the corresponding production factory for the production of construction materials.

[0038] Optionally, the capturing of a three-dimensional high-definition image of the interior of the scene to be constructed and converting the three-dimensional high-definition image into a BIM model includes:

[0039] Using a three-dimensional camera to perform surround shooting inside the construction scene to obtain the three-dimensional high-definition image;

[0040] The three-dimensional high-definition image is cut and processed to obtain several groups of high-definition image slices, and three-dimensional reconstruction calculations are performed on each group of high-definition image slices using three-dimensional reconstruction software to obtain several sub-BIM models, and the sub-BIM models are spliced ​​together to obtain the BIM model.

[0041] In the embodiments of the present invention, a 3D camera is a device capable of capturing the three-dimensional shape and size of an object, and is widely used in fields such as industrial inspection, medical imaging, virtual reality, etc. The 3D camera in the present invention uses existing products, such as the FM series of Tuyang Technology, which provides a high-speed dynamic 3D camera with a depth resolution of 1 million, adopts a Global shutter sensor, supports a gigabit Ethernet interface and POE power supply; the AL-M DLP structured light 3D camera of Xingyuanzhe Technology, which is suitable for high-precision 3D reconstruction such as precision machining and painting, and has anti-reflection characteristics; the Mech-Eye industrial-grade 3D camera of Mekarmand Robotics, which has high precision, high speed, and anti-environmental light interference, and is suitable for 3D vision applications at different distances of far / middle / near, and so on.

[0042] The present invention first cuts and groups the aforementioned captured three-dimensional high-definition images. For example, each space is cut in units of 1°, and the high-definition image slices in each space form a group. Then, 3D reconstruction software is used to perform 3D reconstruction on each group to obtain a sub-BIM model corresponding to the space. The sub-BIM models are matched according to the shooting space position information of the three-dimensional high-definition images to complete the splicing, thereby obtaining a high-precision BIM model that completely corresponds to the interior of the to-be-constructed scene.

[0043] The 3D reconstruction software can extract the point cloud data of each construction object inside the to-be-constructed scene from each high-definition image slice, and then construct it into a 3D model based on the point cloud data. Of course, within each group, there may be overlaps in the content included in the high-definition image slices, and the overlapping parts need to be processed when generating the sub-BIM model. The 3D reconstruction software can be selected from MVE (Multi-View Environment), Meshroom, MicMac, etc., and the present invention does not limit this.

[0044] Optionally, the formwork matching requirement data includes formwork materials, layout parameters, and formwork processing parameters.

[0045] Optionally, the layout parameters include sub-layout parameters corresponding to multiple construction object types.

[0046] In the embodiments of the present invention, the formwork matching requirement data mainly includes formwork materials, layout parameters, and formwork processing parameters. As Figures 2 - 5 shown, the formwork materials include the types of materials to be used (including color, texture, material, etc.) and their corresponding dimensions, such as 1830mmx915mm formwork. The layout parameters include sub-layout parameters for multiple construction object types such as columns, beams, walls, and slabs. For example, the layout parameters for columns are:

[0047] 1. The formwork sequence of the column selects "long side wraps short side";

[0048] 2. The side formwork extension length is 0, and a 20-mm gap is left at the bottom of the column formwork.

[0049] 3. At the intersection of the column and the beam, the column formwork is set to "split the beam bottom formwork".

[0050] 4. The downward extension length of the outer formwork of the edge column is set to 100 mm, and the upward extension length is 20 mm.

[0051] The layout parameters of the beam are as follows:

[0052] 1. The beam formwork sequence is set to "beam side wraps beam bottom".

[0053] 2. The formwork extension length is 0, and the upward extension length of the outer formwork of the side beam is set to 20 mm.

[0054] 3. At the intersection of the main beam and the secondary beam, the bottom formwork is set to "the bottom formwork of the secondary beam abuts against the main beam".

[0055] 4. "The side formwork of the secondary beam abuts against the main beam".

[0056] The layout parameters of the wall are as follows:

[0057] 1. The formwork layout direction is set to "vertical first", and the secondary target is set to "more whole plates".

[0058] 2. The side formwork extension length is 0, and the height of the gap left at the bottom of the wall formwork is 20 mm.

[0059] 3. The downward extension length of the formwork at the outer wall is 100 mm, and the upward extension length is 20 mm.

[0060] The layout parameters of the slab are as follows:

[0061] 1. The long side direction of the formwork is set to "room long side first".

[0062] 2. The formwork layout sequence is set to "more whole plates".

[0063] The formwork processing parameters are, for example:

[0064] 1. The narrow plate width ignored by the formwork is set to 10 mm, and the area of the ignored hole is 0.30 m².

[0065] 2. The maximum narrow plate width of the wall column in the vertical direction is set to 150 mm, and the maximum narrow plate of the beam and slab is set to 150 mm.

[0066] 3. The processing method of non-standard plates is selected as "centralized processing according to the selected area".

[0067] Optionally, the large language model is used to process the formwork requirement data, and a formwork parameter set is obtained, including:

[0068] Use a large language model to process the formwork demand data, obtain a number of formwork parameters corresponding to each type of construction object, and integrate each of the formwork parameters into the formwork parameter set.

[0069] In the embodiment of the present invention, the large language model can achieve accurate semantic understanding and analysis. The present invention uses the large language model to perform semantic analysis on the formwork demand data (i.e., the aforementioned formwork materials, layout parameters, formwork processing parameters) set by the designer, extracts the corresponding feature matrix, that is, the formwork parameters. Multiple formwork parameters correspond to specific types of construction objects, and then all the formwork parameters are integrated to obtain the formwork parameter set.

[0070] The above-mentioned formwork demand data set by the designer can be in a non-specified format, for example, described in natural language. The large language model can process it and extract the corresponding formwork parameters. The large language model is preferably a Transformer-based model, and can also use an Autoencoder-Based Model, a Sequence-to-Sequence Model, etc., or directly use existing large language model products such as ChatGPT.

[0071] Optionally, using the formwork parameter set and the formwork standard library to perform formwork processing on the BIM model to obtain a formwork project file, including:

[0072] Select the corresponding standard formwork from the formwork standard library using the formwork materials in the formwork parameter set, adjust the dimensions of each selected standard formwork based on the layout parameters to obtain the project formwork; determine the processing parameters of each project formwork according to the formwork processing parameters;

[0073] Convert the BIM model after formwork processing into a specified format, that is, obtain the formwork project file.

[0074] In the embodiment of the present invention, there are various standard formworks stored in the formwork standard library. First, select the corresponding standard formwork from it according to the formwork materials, then adjust its dimensions to correspond to the aforementioned layout parameters, and then configure the corresponding processing parameters. Through the above iterative processing, the formwork processing of the BIM model can be completed to obtain the formwork project file. The formwork project file needs to be converted into a specified format, for example, a format adapted to a specific software, so as to facilitate subsequent viewing and revision by the designer.

[0075] Optionally, the step of selecting the corresponding standard formwork from the formwork standard library using the formwork materials in the formwork parameter set includes:

[0076] For the sub-structures in the BIM model, if the number of corresponding standard moldings in the mold standard library is multiple, use a large language model to process the note attribute information of the to-be-constructed scene to predict the visibility of the sub-structure after construction is completed;

[0077] If the visibility of the sub-structure after construction is completed is invisible, randomly select one from the corresponding multiple standard moldings; otherwise, select one from the corresponding multiple standard moldings based on the standard moldings selected by other sub-structures adjacent to the sub-structure.

[0078] In the embodiments of the present invention, there may be multiple standard moldings in the mold standard library that are suitable for a certain sub-structure, such as molding A made of plastic, molding B made of metal, textured molding C, non-textured molding D, etc. In this regard, the present invention first uses a large language model to process the note attribute information of the to-be-constructed scene to predict the visibility of the sub-structure after construction is completed, including visible and invisible. If the sub-structure is invisible after construction is completed, for example, located above the ceiling, a standard template can be randomly selected; if the sub-structure is visible after construction is completed, it can be analyzed based on the specific types of the standard moldings selected by multiple other sub-structures adjacent to the sub-structure. For example, select the same standard molding as other sub-structures of the same type, or analyze the molding rules such as texture / material distribution rules based on the standard moldings of multiple other sub-structures to determine its own standard template that adapts to the rule. Of course, if it is still impossible to confirm, the situation of the sub-structure can be output externally and manually selected by the designer.

[0079] The note attribute information can be the basic design information corresponding to the to-be-constructed scene input by the designer, such as whether a ceiling is required, the ceiling height, the use of the to-be-constructed scene, etc.
