This type of software is widely used in design communication, scheme optimization, and material selection, and has become an indispensable tool in modern renovation.
[0003] These software programs share a similar basic framework and functions. For example, they first construct a 3D spatial framework based on the floor plan to perform spatial modeling; then, they use built-in material packs to realistically reproduce the texture and reflective properties of materials such as tiles, wood flooring, and paint to perform material simulation; finally, by dragging and dropping furniture, lighting, and other soft furnishing models into the scene, they can achieve soft furnishing matching and ultimately generate 3D renderings and illustrations for designers to reference.
[0004] The accuracy of 3D simulation rendering in reproducing real-world scenes is crucial, directly impacting the client's judgment of the design. However, light sources, especially external sunlight, are often overlooked in current mainstream design software due to their intangible nature. Current simulations cannot accurately reproduce the appearance of interior designs under simulated sunlight. Therefore, improvements are necessary to further enhance the realism of simulated scenes.

Detailed Implementation
[0011] To make the objectives, technical solutions, and advantages of this invention clearer, the 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 merely illustrative and not intended to limit the invention.
[0012] It is understood that the terms "first," "second," etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish the first unit or module from another unit or module. For example, without departing from the scope of this application, the first script may be referred to as the second script, and similarly, the second script may be referred to as the first script.
[0013] Figure 1 An application environment diagram for the intelligent data processing method for interior design provided in the embodiments of this application is shown, such as... Figure 1 As shown, this application environment includes terminal device 110 and cloud device 120.
[0014] The cloud device 120 can be an independent physical server or terminal, or a server cluster consisting of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud servers, cloud databases, cloud storage, and CDN.
[0015] Terminal device 110 can be a smartphone, tablet, laptop, desktop computer, etc., but is not limited to these. Terminal device 110 and cloud device 120 can be connected via a network, which is not limited herein. This application can run on terminal device 110 or cloud device 120.
[0016] like Figure 2 As shown, in one embodiment, an intelligent data processing method for interior design is proposed. This embodiment mainly applies this method to the above-mentioned... Figure 1 Taking cloud device 120 as an example, it is used to transmit data from terminal device 110 to cloud device 120 for online simulation. A smart data processing method for interior design may specifically include the following steps: Step S10: Obtain the 3D model of the building to be simulated, and obtain the orientation and geographical coordinates of the building to be simulated.
[0017] In this embodiment, the obtained 3D model of the building to be simulated can be as follows: Figure 3As shown, the model can be a model from various 3D modeling software such as Revit and SketchUp. Orientation refers to the overall east, west, south, and north orientation of the building, and geographical coordinates are the latitude and longitude coordinates. In this embodiment, the user can directly input the city or province where the building is located. The system has a built-in default correspondence between cities and geographical latitude and longitude coordinates to improve ease of use. The east, south, west, and north orientations or specific orientations of the 3D model can be automatically read by the system from the floor plan or manually set by the user.
[0018] Step S20: Construct a Cartesian coordinate system in three-dimensional space based on the orientation of the three-dimensional model, and position the three-dimensional model at the center of the spatial coordinate system.
[0019] In this embodiment, the origin of the spatial coordinate system can be the geometric center of the 3D model, and its horizontal x and y axes can be, for example, due east and due south. The 3D model can be set in a Cartesian coordinate system based on the actual geographical orientation of the building to be simulated.
[0020] Step S30: Construct a surface light source, which is used to generate simulated sunlight perpendicular to the emitting plane. The line connecting the geometric center of the emitting plane and the origin of the rectangular coordinate system is perpendicular to the emitting plane.
[0021] In this embodiment, a rectangular surface light source is created in the 3D engine. To more accurately simulate sunlight, a surface light source that produces parallel light is constructed. Understandably, a point light source that is far enough away from the model can also be used to simulate a surface light source.
[0022] Step S40: Obtain the simulation time. Based on the geographic coordinates and the simulation time, obtain the spatial position of the surface light source in the rectangular coordinate system so that the surface light source simulates the spatial position of the real sun.
[0023] In this embodiment, the simulation time can be in hours, with the sun in different positions at different times. The simulation time can be set by the user, allowing for a clear understanding of the indoor ambient light levels at different times. This also facilitates the arrangement of hard furnishings and soft furnishings. For example, it helps avoid placing sofas in areas exposed to direct sunlight, or placing certain furniture in locations where it will be exposed to sunlight for extended periods, thereby improving the accuracy and comfort of the design.
[0024] Step S50: Simulate illumination of the three-dimensional model using the surface light source to obtain sunlight illuminance information; simulate illumination of the three-dimensional model using the light-emitting module in the three-dimensional model to obtain lamp illuminance information; superimpose the sunlight illuminance information and the lamp illuminance information to obtain simulated illuminance information.
[0025] In this embodiment, the illuminance information can be as follows: Figure 4 The heat map shown can also represent the light intensity at various locations in an indoor room in the form of numerical maps, contour maps, etc. This application superimposes sunlight illuminance information with artificial light illuminance information for simulation, resulting in more realistic and natural lighting. Since the intensity of sunlight is often significantly higher than that of indoor artificial light sources, this method can produce more natural lighting. Figure 5 The indoor environment shown has more realistic shadows and lighting, avoiding the artificial look caused by non-realistic sunlight light sources used in traditional simulations.
[0026] In this embodiment, the sun's position is calculated based on real geographic coordinates and time, which is superior to traditional static lighting models, achieving high-precision hybrid lighting simulation. The superposition of natural and artificial light conforms to the lighting interaction effects of real-world scenarios. It can provide realistic indoor sunlight simulations at any time, based on the user's actual needs, such as different latitudes and longitudes, offering interior designers a more realistic design environment. The high simulation accuracy facilitates refined construction and improves design quality.
[0027] In a preferred embodiment, the method for obtaining the simulation time and, based on the geographic coordinates and the simulation time, determining the spatial position of the area light source in the Cartesian coordinate system is as follows: Obtain the simulated time and convert it into a day sequence number; Obtain the declination angle of the surface light source: Obtain the time angle of the surface light source: Obtain the elevation angle of the surface light source: Where n represents the day number, δ represents the declination angle, and H represents the hour angle. Δλ represents the elevation angle, t represents the local time in hours, Δλ represents the difference between the longitude of the location of the simulated building and the central longitude of the time zone of that region, and ϕ represents the latitude of the location of the simulated building.
[0028] In this embodiment, Beijing is located at 116.4°E, with the center longitude of the UTC+8 time zone at 120°, therefore Δλ = -3.6°. The day number refers to the day of the year. 15 represents the difference in longitude per hour, i.e., 360° / 24h = 15° / h. This application provides a simplified method for calculating the simulated sunlight position. The accuracy of this method meets the requirements. By calculating the elevation and azimuth angles, the spatial direction of the simulated surface light source in the coordinate system can be obtained. Understandably, the surface light source should be sufficiently far from the building model, and the plane should be large enough to avoid edge scattering.
[0029] In a preferred embodiment, the method further includes: Acquire a number of preset virtual scenes, the virtual scenes including at least one of the following preset scenes: morning scene, noon scene, dusk scene, cloudy scene, rainy scene, and sunny scene; In each of the different preset scenarios, the color temperature and brightness of the surface light source are different.
[0030] In a preferred embodiment, the illuminance corresponding to the noon scene is 100,000-120,000 lux, and the color temperature is 5,500-6,500 K; the illuminance corresponding to the morning scene is 20,000-50,000 lux, and the color temperature is 4,000-5,000 K; the illuminance corresponding to the dusk scene is 5,000-15,000 lux, and the color temperature is 2,000-3,500 K; the illuminance corresponding to the cloudy scene is 10,000-30,000 lux, and the color temperature is 6,500-7,500 K; and the illuminance corresponding to the rainy scene is 5,000-10,000 lux, and the color temperature is 7,000-9,000 K.
[0031] In the embodiments of this application, some preset environmental scenarios are provided, so that users can easily switch to the target scene mode with one click, thereby obtaining different environments that are conducive to adjusting the color temperature and brightness of sunlight at noon and early morning. At the same time, noon and early morning correspond to different times, so users can switch to the accurate virtual scene with one click, which meets the needs of fine simulation of natural lighting in interior design.
[0032] In a preferred embodiment, the method further includes: Obtain the surrounding environment of the building to be simulated. Different surrounding environments correspond to different ambient light diffuse reflectance. Obtain the horizontal reference plane of the building in the three-dimensional model, construct an annular diffuse reflection zone around the three-dimensional model on the horizontal reference plane around the three-dimensional model, and make the diffuse reflectance of the annular diffuse reflection zone equal to the diffuse reflectance of the real surrounding environment of the building to be simulated in reality. The three-dimensional model is simulated and illuminated based on the annular diffuse reflection band to obtain diffuse reflection illuminance information.
[0033] In this embodiment, for buildings such as street-front shops, in addition to considering the direct sunlight, the influence of diffused sunlight on indoor lighting can also be taken into account. Different diffuse surfaces have different diffuse reflection intensities; for example, green belts and brick pavements have different diffuse reflection intensities. Furthermore, by simplifying the complex 3D environment into a toroidal geometry, the number of ray tracing samples is reduced, thus lowering the computational requirements.
[0034] This embodiment first determines the diffuse reflectance of the surrounding built environment, such as vegetation, building complexes, and ground materials, through on-site measurements or database matching. Then, a ring-shaped geometry is created around the 3D model, assigning it the same diffuse reflectance as the real environment to simulate the indirect reflection of ambient light. The contribution of this ring-shaped geometry to the indirect lighting inside the room is calculated using a lighting engine and superimposed on the total illuminance information. It is understood that the simulation engine for calculating the total illuminance of the interior space automatically considers the global illumination resulting from multiple bounces of light within the room; only the light source needs to be introduced, without additional calculations. The building reference plane can refer to the height of the ground on which the building is located.
[0035] In a preferred embodiment, the annular diffuse reflection band includes several consecutive sub-sectors, and the diffuse reflectance of each sub-sector is equal to the diffuse reflectance of the actual surrounding sub-environment area of the building to be simulated corresponding to the three-dimensional model.
[0036] In the embodiments of this application, it is considered that for some house types, such as roadside shops and Japanese-style detached houses, one side of the building may be a road and the other half is a lawn. Different ground types have very different diffuse reflectance. In this case, if the average value method is used to calculate the average diffuse reflectance of the surrounding environment, it is not possible to simulate the sunlight of each room.
[0037] Therefore, this embodiment divides the annular strip into N consecutive sectors, enabling the system to support non-uniform reflectivity distribution. The sectors can be divided in an average manner, such as dividing each sector into 30° sections, or they can be divided according to the actual environmental conditions, such as dividing a water surface into one sector and a lawn into another.
[0038] In a preferred embodiment, the method further includes: The sunlight illuminance information and the diffuse reflection illuminance information are superimposed to obtain the solar illuminance information; The entire exposeable surface in the 3D model is divided into several sub-planes: , in N is the number of sub-planes in the segmentation. Indicates all exposing surfaces. Denotes the i-th subplane. This represents the area of the i-th subplane. This indicates the direction of the normal vector of the i-th subplane; Obtain the solar illuminance information of each subplane at different times of the day, integrate and sum the solar illuminance information for all times on a daily basis, and obtain the total solar reception value of each subplane: ; in, This represents the total sunlight received by the i-th subplane. This indicates the step size for dividing a day, and this indicates the total number of time segments. express Sunlight at any moment and the normal to the subplane The included angle, express Information on sunlight illuminance at any given time.
[0039] In this embodiment, the entire interior wall surface, floor surface, and hard-decorated interior surfaces can be divided into uniform rectangular grids of equal size. The grid density can also be dynamically and adaptively adjusted based on curvature or light gradient. A fixed time step, such as 10 minutes, can be used to discretize a day, thereby calculating the total sunlight received value for each sub-plane. This facilitates the calculation of whether the material strength in each area can withstand the total ultraviolet radiation and the calculation of material lifespan. It also facilitates the design of indoor sunroom areas and vegetation areas.
[0040] In a preferred embodiment, the method provided in this application may also exist in the form of a computer-executable program unit or program module, for example, as an intelligent data processing device for interior design, comprising: The orientation and geographic coordinate acquisition module is used to acquire the three-dimensional model of the building to be simulated, and to acquire the orientation and geographic coordinates of the building to be simulated. A Cartesian coordinate system construction module is used to construct a Cartesian coordinate system in three-dimensional space based on the orientation of the three-dimensional model, and to position the three-dimensional model at the exact center of the spatial coordinate system. A surface light source construction module is used to construct a surface light source, which is used to generate simulated sunlight perpendicular to the emitting plane. The line connecting the geometric center of the emitting plane and the origin of the rectangular coordinate system is perpendicular to the emitting plane. The simulation time acquisition module is used to acquire the simulation time and, based on the geographic coordinates and the simulation time, obtain the spatial position of the surface light source in the rectangular coordinate system so that the surface light source can simulate the spatial position of the real sun. The simulated illuminance information acquisition module is used to simulate irradiation of the three-dimensional model using the surface light source to obtain sunlight illuminance information; to simulate irradiation of the three-dimensional model using the light-emitting module in the three-dimensional model to obtain lamp illuminance information; and to superimpose the sunlight illuminance information and the lamp illuminance information to obtain simulated illuminance information.
