Description

Technical Field

[0001] The present invention belongs to the field of building information technology, and particularly relates to a method and system for generating a building model based on a single-story floor plan. Background Art

[0002] In most buildings, the apartment types and layouts are identical across the middle floors. The overall layout of each floor can be broken down into a combination of smaller units, creating the overall layout of a single floor. Traditional design methods combine the apartment types and overall layout of several middle floors into a single design plan. This approach reduces design effort but hinders a clear and intuitive overview of the building's overall structure. Furthermore, designing each floor remains a labor-intensive process. Current design tools are unable to automatically generate a building by consuming the design of each floor, failing to meet user needs in terms of capturing user requirements, intuitive presentation, comprehensive data, and easy modification. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a method and system for generating a building architectural model based on a single-story floor plan, so as to improve the efficiency of building design by intelligently merging several basic floor plans selected from the floor plan library into a whole single floor, and then generating an entire building architectural plan based on the single floor.

[0049] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0050] Unless otherwise specified, the terms (including technical terms) used in this embodiment have the meanings commonly understood by those skilled in the art. In addition, it is understood that terms defined in commonly used dictionaries should be understood to have the same meanings as those in the context of the relevant fields, and should not be understood as idealized or overly formal.

[0051] The following are some definitions of terms:

[0052] Apartment layout library: refers to a database that stores a large number of commonly designed apartment layouts in scenarios such as hotels and residential buildings.

[0053] Basic apartment type: refers to the small apartment type selected from the apartment type library for combination.

[0054] Single-story apartment: refers to the overall apartment type on one floor formed by combining several basic apartment types.

[0055] Building construction: refers to an entire building formed by duplicating and stacking single-story apartment units.

[0056] House type data: refers to a collection of house type data.

[0057] House component: refers to the data of a wall, beam, slab, column, etc. within the house.

[0058] Elevation: used to describe a specific height perpendicular to the horizontal plane, referring to the entire plane at this height;

[0059] Wall (straight wall): Contains parameters such as bottom elevation, wall height, wall start point, wall end point, and thickness (horizontal thickness). A wall is a cube fully described by these parameters.

[0060] Beam: Contains parameters such as top elevation, beam height, and beam width. A beam is a cube fully described by these parameters.

[0061] Slab (floor): Contains parameters such as elevation (the elevation of the top surface of the slab), thickness, and profile (2D profile in the top view). A floor is a cube fully described by these parameters.

[0062] Column: Contains parameters such as bottom elevation, column height, length, and width. A column is a cube fully described by these parameters.

[0063] Core tube: In the central part of the building, the central core tube is formed by the elevator shaft, stairs, ventilation shaft, cable shaft, public toilets, and some equipment rooms, forming an outer frame and inner tube structure with the outer frame.

[0064] Floor elevation: For non-physical components, the height and actual floor level can be marked.

[0065] Reference elevation: For components without physical entities, only marking the height cannot represent the actual floor level.

[0066] This embodiment provides a method for generating a building model based on a single-story floor plan. The method first reads a selected basic floor plan and analyzes the connection points of the selected floor plan. The connection points of these basic floor plans are then connected to generate a single-story floor plan. Finally, the component data of the single-story floor plan is copied to generate a building plan.

[0067] Figure 1 A flowchart of a method for generating a building model based on a single-story floor plan, provided by this embodiment, is shown. This embodiment is applicable to generating a building model based on a single-story floor plan. The method can be performed by a system for generating a building model based on a single-story floor plan. The system can be implemented in software and / or hardware and can be configured in an electronic device, such as a terminal device or a server.

[0068] like Figure 1 As shown, the method specifically includes the following steps:

[0069] Step S1: Obtain several basic apartment types selected by the user from an apartment type database, and combine the several basic apartment types.

[0070] In this embodiment, "combine" and "merge" represent different processing procedures. Combining means establishing relationships between multiple sets of data for subsequent calculations without modifying the data in each combination; merging combines multiple sets of data into a single set of data. After the merger, only the last merged set of data remains.

[0071] For example, the user can Figure 2 The interface shown completes the basic apartment type selection operation.

[0072] For example, the display interface can be divided into building design and apartment recommendation selection areas. The building design selection area provides building type options such as "three households per elevator" and "four households per elevator"; the apartment recommendation selection area provides an apartment search function, such as searching or filtering apartment plans that the user is interested in based on parameters such as room rate and budget; it can also provide the function of switching and filtering in different sub-libraries of the apartment database, for example, switching between the public library and the enterprise library. In this manual, apartment type and apartment plan represent different concepts. Apartment type refers to the actual apartment structure, which is an entity in 3D space; the apartment plan is only a floor plan that simply expresses the apartment type from a bird's-eye view.

[0073] Step S2: Merge the combined basic apartment types into a single-story apartment type.

[0074] like Figure 3 As shown, step S2 specifically includes:

[0075] Step S201: Analyze the entrances and exits of basic apartment types.

[0076] Each apartment data is generated by the user operating the tool, so the coordinate origin of each apartment data will be randomly located, and a unified coordinate system is required. Traverse the selected basic apartment types and analyze the location, orientation, and other information of the apartment exits and entrances, as follows:

[0077] (1) By traversing all the components of the apartment type, we can determine the outer bounding box of the entire apartment type. Taking the upper left corner of the outer bounding box as the new coordinate origin, we can convert the coordinates of all other components to the coordinates when the upper left corner of the outer bounding box is the origin. This unifies the coordinate system of all apartment type data.

[0078] (2) Search for doorway data along the top, bottom, left, and right sides of the outer bounding box. If no doorway data exists, then this apartment needs to have an entrance or exit added. If so, add it to the doorway list.

[0079] (3) Traverse the doorway list, analyze the wall length along the doorway, record the wall length, and add the wall length to the entrance and exit list when the wall length on one side exceeds a threshold. In a feasible embodiment, the threshold value is 200 mm.

[0080] Step S202: Combine a pair of basic apartment types.

[0081] The apartment data was selected in the previous step. The doorway list is a list that uses doorways as indexes to point to specific apartment data. For example, if apartment types A / B / C were selected for merging in the previous step, and each apartment type analyzed yielded three doorways, a / b / c, then these three doorways would be added to the list. Each time, two doorways are taken from the beginning or end of the list, and the apartment data they point to is retrieved from the doorways. These two sets of apartment data are merged into one set and then added back to the list. This process is repeated until the list capacity reaches 1, leaving two doorways remaining. Finally, all selected apartment types are merged. After merging two doorways, the specific doorway selected to return to the doorway list depends on a default or preset combination strategy. For example, the default combination strategy might be to select the doorway closest to the remaining list. In the above example of doorways a / b / c, the doorway closest to c would be selected.

[0082] This embodiment is described by taking the merging of a pair of apartment types as an example. The apartment type data is retrieved from the door opening list in step S201 in reverse order, and the first two apartment type data in the list are taken as a pair of apartment types.

[0083] Divide a pair of apartment types into type A and type B and proceed as follows:

[0084] (1) Traverse the exits of apartment type A and search for an entrance that matches apartment type B. If found, translate apartment type A along the positive direction of the y-axis by a distance equal to the height of the outer bounding box of apartment type A, record it as the upper apartment type, and proceed to step S203.

[0085] (2) Traverse the exits of apartment B and search for an entrance that matches apartment A. If found, translate apartment B along the positive direction of the y-axis by a distance equal to the height of the outer bounding box of apartment B, record it as the upper apartment, and proceed to step S203.

[0086] Step S203: Generate a core tube.

[0087] Shift the upper unit 4200mm in the positive y-axis direction to create space for the corridor, elevator, and stairwell. This way, the left ends of the upper and lower units are aligned on the x-axis.

[0088] Generate a corridor: Take the smaller value of the rightmost end of the x-axis direction of the outer bounding boxes of the upper and lower units as the length, and 4200mm as the width to generate the floor slab, which is the corridor space.

[0089] Generate an elevator room: Take the center line of the corridor and dig a floor hole with a length of 1800mm (in the x-axis direction) and a width of 3000mm (in the y-axis direction) on the left side of the x-axis as the vertical opening of the elevator room.

[0090] Generate a stairwell: Take the center line of the corridor and dig a floor hole with a length (x-axis direction) of 5000mm and a width (y-axis direction) of 3000mm on the right side of the x-axis as the vertical opening of the stairwell.

[0091] If there are other apartment types to be merged, the process returns to step S202 and continues merging until all selected apartment types are merged. In fact, a core tube is regenerated each time a merge is completed.

[0092] Step S204: prepare and export a single-story apartment.

[0093] During the specific implementation, some intermediate data may be generated in the aforementioned steps, which may need to be released or retained. Before exporting, it may also be necessary to apply for some resources to facilitate computer calculations, so a preparation stage is required.

[0094] Check if there is a wall around the entrance and exit mark. If not, add a wall. In practice, this is a relatively rare situation. If there is no wall near the coordinates of the entrance and exit mark, add a wall. Check if the entrance and exit wall connection is complete to ensure the integrity of the wall connection. Then add the upper floor slab to the entrance and exit connection and output it to the display interface of the design software. Figure 4 The designers then make the final adjustments to the single-story apartment layout. It's worth noting that these adjustments are necessary because the merge and export process is a pre-programmed process, which inevitably results in some "strange" results, such as corridors leading nowhere or confined spaces with no entrances. This is when the designers need to refine the process and optimize the final single-story apartment layout.

[0095] Step S3: Obtain the number of floors of the building determined by the user, and superimpose single-story apartment types according to the number of floors to generate the middle part of the building model.

[0096] like Figure 5 As shown, the specific steps of step S3 include:

[0097] Step S301: Analyze the single-story apartment and calculate the height of the single-story apartment.

[0098] The current floor may be experiencing settlement. Components related to settlement need to be marked in the basic unit layout. This way, in single-story units, it's clear which components are subject to settlement. The calculated unit height needs to remove the "downward protrusion" of the settlement components.

[0099] Step S302: Generate floor elevation.

[0100] That is, generate the floor elevation in the building plan based on the information in the previous step, and then generate the reference elevation based on the original elevation of the single-story apartment.

[0101] A building plan is a repeated stack of single-story unit plans. A single-story unit plan can be thought of as data on a 2D plane. The building plan is simply a stack of 2D single-story unit plan data on the Z-axis of 3D space. Each floor has the same data, but at different elevations. This is the final building plan data, the plan used to generate the building model.

[0102] Regarding floor elevation and reference elevation, the comparative explanation is as follows:

[0103] The original elevations of a single-story apartment include the bottom elevation and the top elevation (i.e. the lowest and highest elevations); the original bottom elevation and top elevation of a single-story apartment will eventually become the floor elevations; the elevation in the middle will eventually become the reference elevation.

[0104] Step S303: Copy the component.

[0105] Based on the information from the previous step, traverse the floor elevations in the building plan, then take out the components from the reference elevation mapping of the single-story apartment, perform deep cloning, and put them into the reference elevation mapping of the corresponding floor elevation.

[0106] The cloning process can be thought of as follows: For example, if a chair is placed at a certain elevation in the original apartment plan, this elevation will be mapped to a reference elevation in the final building plan, and the chair will be copied there. Generally, any other components at the original elevation will be copied to the mapped elevation in the final building plan.

[0107] Deep cloning is a computer term for object copying. Simply put, it means that not only the basic data held by the object itself is copied, but also the object data held by the object is copied.

[0108] Step S4: Add a roof model and a basement model to the middle part of the building model to generate a complete building model.

[0109] Adding roofs and basements can be done manually, outside of the main building generation process. There are no specific restrictions on how to do this. Typically, you upload a roof model and place it at the top of the building. For basements, you design the unit layout separately.

[0110] Building model effect Figure 6 As shown in the figure, the building structure data of the building model includes floor elevations, reference elevations for each floor, wall, beam, slab, column, and opening data for each floor. This data describes the coordinates and parameters of each apartment component. This data, as output, can be used as input for models and construction drawings in cloud design tools.
