DETAILED DESCRIPTION

This application provides a VR-based virtual reality home design preview system and method to solve the technical problems in the prior art that the design solutions cannot fully meet user expectations and it is difficult to accurately grasp user needs.

The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Embodiment 1

As shown in FIG1 , the present application provides a VR-based virtual reality home design preview system, the system comprising:

The first initial floor plan receiving module 10 is used to receive a first initial floor plan of a first user, wherein the first initial floor plan has a load-bearing wall mark.

Specifically, the system has the function of receiving an initial floor plan submitted by a first user. The first initial floor plan is a floor plan specifically for the first user, and the location and range of the load-bearing walls are prominently marked in this floor plan. The load-bearing wall identification may be highlighted with a specific symbol, color or line. For example, the load-bearing wall can be drawn with a thick solid line, or filled with a specific color (such as red) to distinguish it from other non-load-bearing walls. This identification is included in the floor plan of the floor plan, clearly showing the location of each load-bearing wall in the house structure. It also comes with relevant text descriptions or annotations to further explain the specific properties of the load-bearing wall, such as the thickness of the wall, material and other information. Through such a clear load-bearing wall identification, the system can accurately follow the safety principles of the building structure when processing the floor plan design and decoration plan in the future, and avoid making unreasonable or dangerous renovation suggestions. For example, if the floor plan shows that there is a continuous load-bearing wall mark on one of the long sides of the house, then the design will not consider large-scale wall demolition or window opening on this side to ensure the overall structural stability of the house. The overall stability and safety of the house are guaranteed. Based on the accurate house structure, including the distribution of load-bearing walls, the layout of each room and functional area can be planned more accurately to improve space utilization.

The requirement list receiving module 20 is used to receive the subspace size requirement list and the subspace decoration attribute requirement list of the first user.

Specifically, the system will obtain the first user's detailed demand information about each subspace of the house. The subspace size requirement list refers to the specific size settings that the user expects for each independent subspace (such as bedroom, kitchen, bathroom, etc.). For example, the user may want the length of the bedroom to be 4 meters and the width to be 3.5 meters; the area of the kitchen is not less than 8 square meters, etc. This list presents the user's requirements for the size of each subspace in a clear data form. The subspace decoration attribute requirement list covers the user's preferences and expectations for each subspace in terms of decoration style, color matching, material selection, lighting requirements, etc. For example, the user may require the bedroom to use warm warm colors and wooden floors; the kitchen should adopt a modern and simple style and be equipped with stainless steel kitchenware, etc. By receiving these two lists, the system can understand the user's personalized needs more accurately, thereby providing clear guidance and basis for generating decoration plans that meet user expectations. For example, if the user specifies in the subspace size requirement list that the length of the living room should be 6 meters, and in the subspace decoration attribute requirement list that he hopes the living room should adopt a European classical style and marble floor, then the system will focus on these specific size and decoration attribute requirements in the subsequent design and solution generation, accurately capture the user's specific size and decoration attribute requirements for each subspace, and achieve highly personalized decoration solution design to meet the user's unique needs and preferences.

A candidate decoration scheme set generation module 30, the candidate decoration scheme set generation module 30 searches for decoration schemes based on the first initial floor plan, the load-bearing wall identifier, the subspace size requirement list and the subspace decoration attribute requirement list, and generates a candidate decoration scheme set, wherein the candidate decoration scheme set includes multiple candidate decoration schemes, and any candidate decoration scheme carries a material list.

Specifically, the system will comprehensively utilize the key information of the first user received previously to search and generate decoration plans. The system uses the first initial floor plan as the basic framework, fully considers the load-bearing wall markings therein, and clarifies the unchangeable parts of the house structure to ensure that the generated plan meets the building safety specifications. Combined with the subspace size requirement list and the subspace decoration attribute requirement list, the system matches and screens in its internal database or algorithm model. During the search process, the system will find multiple qualified decoration plans to form a candidate decoration plan set, which contains multiple different design ideas and layout arrangements. Moreover, each candidate decoration plan is accompanied by a detailed bill of materials list. This bill of materials list will clearly list the various decoration materials required, including the name, specifications, quantity, brand and other information of the materials. For example, if a candidate decoration plan designs an open kitchen, its bill of materials list will include details such as cabinet panels, stone countertops, and electrical equipment of specific brands and models. By generating such a comprehensive and rich set of candidate decoration plans and corresponding bill of materials lists, users are provided with a variety of choices and can clearly understand the materials and costs involved in each plan. Generate multiple candidate decoration plans, allowing users to choose from a variety of different design ideas and styles, increasing the possibility of users finding a satisfactory plan and achieving highly personalized service.

The user interaction module establishment module 40 is used to establish a user interaction module, wherein the user interaction module includes a user information interaction port and a VR connection device.

Specifically, the established user interaction module includes the following two key parts: User information interaction port, which is a channel for users to exchange information with the system. It may exist in many forms, such as: Web interface, where users can input their needs, opinions and feedback to the system by filling out forms, selecting options, uploading files, etc. on the web page, and can also obtain prompts, suggestions and solution displays given by the system from the web page. Mobile application interface, where users can interact with the system anytime and anywhere through applications installed on mobile phones or tablets. The application interface has a simple and intuitive operation method, which is convenient for users to use in different scenarios. Instant messaging tools, such as online customer service chat windows, allow users to communicate with customer service staff in real time to solve questions and communicate needs in a timely manner. Through the user information interaction port, users can clearly and accurately convey their ideas and requirements to the system, and can also receive responses and information provided by the system in a timely manner. VR connection device: This is a hardware device that allows users to immerse themselves in a virtual environment. It includes the following features: Head-mounted display, which provides users with an immersive visual experience and displays realistic decoration scenes. Tracking sensors can track the user's head movements and positions in real time, and adjust the display of virtual scenes accordingly according to the user's perspective changes, allowing users to observe the decoration effects in all directions. Handheld controllers allow users to interact with elements in the virtual environment through handheld controllers, such as selecting different decoration materials and adjusting the placement of furniture. Through VR connected devices, users no longer just imagine the decoration effects through flat pictures or texts, but can feel and experience them in an immersive way, as if they were in a real decoration space, so as to evaluate and adjust the decoration plan more intuitively and realistically, enhance user participation, improve the accuracy and satisfaction of the final decoration plan, and enhance the uniqueness and personalization of the decoration plan.

The first recommended decoration plan generating module 50 is used for, when the first user wears the VR connection device, to perform a virtual environment rendering for the first candidate decoration plan in the candidate decoration plan set through the VR modeling platform, and to receive the first preview feedback information of the first user through the user information interaction port, to perform rendering iteration, and to generate a first recommended decoration plan.

Specifically, the first user wears a specially equipped VR connection device. At this time, the system uses the VR modeling platform to build a virtual environment for the first candidate in the candidate decoration plan set. In this virtual environment, through powerful rendering technology, various elements including room layout, furniture placement, decorative details, material texture, lighting effects, etc. are presented in an extremely realistic way, allowing users to be immersed in this decoration space that does not actually exist. At the same time, the system receives the first preview feedback information given by the first user when experiencing this virtual environment through user information interaction ports, such as voice input, handle operation, touch screen, etc. These feedback letters can cover the user's feelings about the space layout, such as thinking that a certain area is too narrow or empty; preference or dissatisfaction with furniture styles and colors; evaluation of lighting effects, feeling that it is too bright or too dark; and even suggestions for adjusting the overall style, etc. After the system obtains these feedbacks, it will immediately modify and update the current rendering, adjust the size and position of furniture, change materials and colors, optimize lighting settings, or re-plan the space layout. After many such feedback and rendering update cycles, the first recommended decoration plan is finally generated that can meet the user's needs and expectations to the greatest extent. For example, the user finds that the kitchen countertop space is insufficient in the VR experience, and gives voice feedback to the system, and the system immediately adjusts the rendering to expand the countertop area. For example, the user feels that the color of the sofa in the living room does not match the overall style, so he selects another color through the handle operation. The system immediately updates the rendering effect. Through such continuous interaction and improvement, the first recommended decoration plan that satisfies the user is finally generated. Through real-time feedback and rendering changes of users in the VR environment, user needs can be accurately met.

Further, based on the first initial floor plan, the load-bearing wall identifier, the subspace size requirement list, and the subspace decoration attribute requirement list, a decoration scheme search is performed to generate a candidate decoration scheme set, including:

Taking the first initial floor plan, the load-bearing wall identifier, the subspace size requirement list and the subspace decoration attribute requirement list as constraints, a historical decoration plan set is collected, wherein any historical decoration plan includes subspace structure design information and subspace decoration material information; taking the consistency of the spatial structure design information as a constraint, the historical decoration plan set is clustered, and the subspace decoration material information of the clustering results is integrated to generate multiple candidate decoration plan sets and a material list; the candidate decoration plan set is established with the multiple candidate decoration plan sets and the material list.

Specifically, the system will combine the original layout of the house in the first initial floor plan, the unchangeable parts indicated by the load-bearing wall mark, the specific size requirements of each room specified in the subspace size requirement list, and the style, color, material and other expectations proposed in the subspace decoration attribute requirement list as a series of strict constraints. Based on these constraints, the system begins to search and collect in the existing rich historical decoration plan database. The historical decoration plan is a record of various actual decoration projects completed in the past. Each historical decoration plan contains detailed subspace structural design information, which covers specific structural design details such as the division of rooms, the connectivity of spaces, and the layout of furniture. At the same time, it also contains subspace decoration material information, such as whether the floor is solid wood or composite material, whether the wall is wallpaper or latex paint, and detailed descriptions of specific brands, models, colors, etc. The system will screen out historical decoration plans with a high degree of matching based on the various constraints proposed by the current user, and form a set of historical decoration plans specially customized for the user.

After obtaining a set of historical decoration schemes that meet various constraints of the user, the schemes in this set are classified and grouped with the consistency of spatial structure design information as the key constraint standard. If the spatial structure designs of multiple historical decoration schemes, such as the layout of the room, the division of space, the location of doors and windows, are the same or very similar, they will be classified into the same category. After clustering, for each clustering result, the system will carefully integrate and analyze the subspace decoration material information contained therein. For example, for multiple schemes belonging to the same cluster, the system will summarize the various decoration materials used by them, including detailed information such as the material type, brand, price, quality, etc. of the floor, wall, ceiling, furniture, etc. Then, by comprehensively considering and integrating this material information, the system will generate multiple different candidate decoration scheme sets. Each candidate decoration scheme set has a unique material combination and matching method. At the same time, a corresponding material list is generated for each candidate decoration scheme set. This list will clearly list the specific information of all materials used in each scheme, including the name, specification, quantity, unit price, total price, etc. of the material, so that users can understand the material cost and composition of each scheme.

After generating multiple candidate decoration schemes and the corresponding bill of materials lists, the system will comprehensively sort out and organize these elements. The system will re-evaluate and optimize each candidate decoration scheme to ensure that it achieves a good balance in terms of design rationality, material coordination, and cost control. According to certain classification standards, such as decoration style (such as modern simplicity, European classical, Chinese traditional, etc.), budget range (high, medium, low) or material quality (high-end, mid-range, economical), these candidate decoration schemes are classified and arranged. In the process of arrangement, the detailed bill of materials corresponding to each scheme set will be closely linked, so that when users view and compare different candidate decoration schemes, they can clearly understand the specific materials and detailed information involved in each scheme at the same time. Finally, a complete and organized candidate decoration scheme set is formed for users to choose and refer to. For example, the system will generate five candidate decoration scheme sets, which are classified into a high-budget scheme set of modern minimalist style (with a high-end material list), a medium-budget scheme set of modern minimalist style (with a mid-range material list), a high-budget scheme set of European classical style, a medium-budget scheme set of Chinese traditional style, and an economical general style scheme set (including an economical material list). Users can select the scheme that best suits their needs from this set of candidate decoration schemes based on their preferences, budget, and preference for decoration style, thereby enhancing the feasibility of the scheme and enriching the diversity of choices.

Furthermore, when the first user wears the VR connection device, a virtual environment rendering is performed on the first candidate decoration scheme in the candidate decoration scheme set through the VR modeling platform, and first preview feedback information of the first user is received through the user information interaction port, and rendering is performed repeatedly to generate a first recommended decoration scheme, including:

The whole-house 3D model and material model list of the first candidate decoration scheme are loaded through the VR modeling platform; decoration rendering of random materials is performed based on the material model list and the whole-house 3D model, and the first user performs a virtual preview through the VR connection device and sends the first preview feedback information; the first preview feedback information is parsed, an iteration request is generated, rendering iteration and decoration scheme optimization are performed, and the first recommended decoration scheme is generated.

Specifically, through a dedicated VR modeling platform, the system begins to process and load the relevant model data of the first candidate decoration scheme. The first is the whole house 3D model, which is a three-dimensional digital presentation of the entire house space, including the three-dimensional shape and position information of all elements such as the shape, size, walls, doors and windows, furniture, and decorations of the room. Users can use VR devices to observe the overall structure and layout of the house in a virtual environment in all directions, as if they were in a real undecorated house space. At the same time, load the material model list. This list records in detail the digital models of various decoration materials used in the first candidate decoration scheme, including visual features such as material texture, color, gloss, and texture. For example, the wood grain of the floor, the granularity of the wall paint, the softness of the fabric, etc., can all be displayed in a realistic effect in the virtual environment. By loading the whole house 3D model and the material model list, users can more realistically feel and evaluate the effect of the first candidate decoration scheme in the VR experience, including the sense of space, aesthetics, and the quality and applicability of the materials. For example, after loading is complete, the user can walk into the room in VR, observe the texture of the sofa up close, feel the real touch of the floor, and even see the reflection effect of light on the surfaces of different materials, so as to more intuitively judge whether the solution meets their expectations.

Based on the loaded material model list and the whole house 3D model, the system will render the decoration of random materials. This means that the system will randomly select different material combinations from the material model list and apply them to the whole house 3D model to present a variety of possible decoration effects. For example, the original living room floor was set to a certain wood material, which may be replaced by marble material in the random rendering; the bedroom wall was originally set to be light blue paint, which will be randomly changed to wallpaper. After wearing the VR connection device, the first user can enter this virtual environment rendered with random materials for preview. During this virtual preview process, the user can move freely and observe every corner and detail like in a real house. Through this immersive experience, the user has an intuitive feeling and judgment of the different material effects rendered randomly, and sends out his opinions and ideas in the form of first preview feedback information. These feedback information may include likes or dissatisfaction with a certain random material, evaluation of the overall effect, suggestions for material matching in a specific area, etc. For example, the user may feel that the randomly rendered kitchen countertop material is not wear-resistant, or that the curtain material in the bedroom does not match the overall style, and thus convey these specific feelings to the system as feedback information.

When the first user sends the first preview feedback information through the VR connection device, the system will conduct in-depth analysis and understanding of this information. The analysis process includes extracting key opinions, evaluations and needs, such as when the user clearly states that he does not like the color or texture of a certain material, or thinks that the layout of a certain space is not reasonable enough. Based on these analysis results, the system will generate corresponding iteration requests. This iteration request will clearly indicate the specific content that needs to be modified and adjusted, such as changing the model and color of a specific material, or replanning the furniture placement in a room. Then, the system reprocesses and updates the current rendering according to the iteration request. This involves a series of complex operations such as recalculating light effects, adjusting material textures, and changing space layout to optimize the decoration plan. After multiple such feedback, analysis, iteration and optimization cycles, the first recommended decoration plan that can best meet user needs and expectations is finally generated. For example, if the user feedbacks that the light in the bedroom is too dim, the system will generate an iteration request to increase the number of lamps or replace brighter bulbs after analysis. After rendering iterations, the lighting effect of the bedroom is improved. For example, if a user reports that the style of the sofa in the living room is not beautiful, the system will replace the sofa model and render and optimize it again until it generates the first recommended decoration plan that satisfies the user.

Further, the first preview feedback information is parsed, an update request is generated, rendering updates and decoration scheme optimization are performed, and the first recommended decoration scheme is generated, including:

The first user marks the local satisfaction level through the user information interaction port to generate the first preview feedback information; based on the first preview feedback information, statistics of the marking information that the satisfaction level is less than the preset level, generate the replacement request, wherein the replacement request includes a scheme replacement request and a local material replacement request; if the replacement request is the scheme replacement request, match the second candidate decoration scheme in the candidate decoration scheme set; render the second candidate decoration scheme, and receive the second preview feedback information, if the satisfaction levels in the second preview feedback information are all greater than or equal to the preset level, generate the first recommended decoration scheme with the second preview feedback information.

Specifically, when the first user views the decoration plan, he uses the user information interaction port to evaluate and mark the satisfaction level for different local areas of the plan. This user information interaction port is a specific area on a web page, an operation interface in a mobile application, or other similar forms of interaction. In each local location, such as the sofa area in the living room, the bedside background wall in the bedroom, the kitchen cabinet, etc., the user selects from the pre-set satisfaction level options, such as "very satisfied", "satisfied", "average", "unsatisfied", "very unsatisfied" and other levels to reflect his feelings about the local area. When the user completes the satisfaction level marking of multiple local areas, these marking information is collected and sorted by the system, thereby generating the first preview feedback information. This feedback information is transmitted to the system in the form of data so that the system can understand the user's specific attitude and opinions on each part of the current decoration plan.

After receiving the first preview feedback information generated by the first user, the system will count and analyze the satisfaction level therein. The system will set a preset level, such as the "satisfied" level. Then, all the mark information in the first preview feedback information whose satisfaction level is lower than the preset level will be filtered out. For example, the parts marked as "general" and "unsatisfied" by the user are all marks below the preset level. Based on these filtered mark information below the preset level, the system will generate corresponding replacement requests. This replacement request is divided into two types, one is a scheme replacement request, which means that the entire local design scheme may need to be readjusted and replaced, such as the overall layout scheme of the bedroom; the other is a local material replacement request, that is, only the materials used in the local area need to be replaced, such as the material of the living room floor. For example, if the user marks the layout of the bedroom as "unsatisfied", then a scheme replacement request for the bedroom will be generated; and if the user marks the material of the kitchen countertop as "general" and hopes to replace it with a better material, this will generate a local material replacement request for the kitchen countertop. In this way, the system can clearly understand the specific parts that the user is dissatisfied with and the type of changes that need to be made, so as to carry out subsequent adjustments and optimization work in a targeted manner.

When it is determined that the generated iteration request belongs to a scheme iteration request, the system will immediately search and match the previously generated candidate decoration scheme set. The system will evaluate and compare each scheme in the candidate decoration scheme set according to the local characteristics and needs of the user. For example, if the user makes an iteration request for the layout plan of the living room, the system will check the layout design of the living room in each scheme in the candidate decoration scheme set. Through a detailed analysis of the relevant parts of each scheme, find a second candidate decoration scheme that better matches the user's needs and expectations. This second candidate decoration scheme has characteristics that are closer to the user's expectations in terms of living room layout and other aspects. For example, the user hopes that the living room has more open space, and the original plan is too crowded. The system finds a plan with a wider living room space in the candidate set as the second candidate decoration plan.

After determining the second candidate decoration plan, the system will render it so that it can be presented to the user in a more realistic and intuitive form. After receiving the rendered second candidate decoration plan, the user will give feedback again to form the second preview feedback information. The system will evaluate the satisfaction level in the second preview feedback information. If all satisfaction levels are greater than or equal to the preset level, it means that the user is generally recognized and satisfied with the second candidate decoration plan. At this time, the system will determine the second candidate decoration plan as the first recommended decoration plan based on the second preview feedback information containing the satisfactory evaluation. Through precise analysis of user feedback and targeted solution changes, user needs can be met more accurately and the satisfaction of the final solution can be improved.

Furthermore, the update request includes a solution update request and a partial material update request, including:

If the replacement request is a partial material replacement request, the partial material replacement rendering is performed according to the material model list, and the satisfaction level of the replaced partial material is received; when the satisfaction level of the replaced partial material is greater than or equal to the preset level, the first recommended decoration plan is generated.

Specifically, if the generated replacement request is a local material replacement request, it means that the user is just dissatisfied with the material used in a certain local area and wants to replace it. The system will select alternative materials that meet the user's needs based on the previously loaded material model list. Then, a separate material replacement rendering is performed for the local area where the user proposes to replace the material. After the local material replacement rendering is completed, the new effect is presented to the user, and the user's satisfaction level for the replaced local material is received. If the user's satisfaction level for the replaced local material is greater than or equal to the preset level, it means that the user is satisfied with this material replacement. At this point, the system will comprehensively consider other parts that have not undergone material replacement and the local materials that are satisfactory after this replacement, and generate the final first recommended decoration plan.

Further, based on the marking information that the statistical satisfaction level of the first preview feedback information is less than a preset level, generating the iteration request includes:

According to the marking information whose satisfaction level is less than the preset level, subspace structure analysis and local decoration material analysis are performed; if the marking information is the subspace structure, the scheme change request is generated; if the marking information is the local decoration material, the local material change request is generated.

Specifically, when the system obtains the marked information with a satisfaction level lower than the preset level, it will conduct in-depth analysis and disassembly of this information. First, the subspace structure analysis is carried out, which is to carefully study the situation of the marked unsatisfactory part in the entire space layout, such as the size and shape of the room, the division of various functional areas and the connection relationship between them. If the marked information indicates that it is a problem with the subspace structure, such as a room is too small to use, or the functional area division is unreasonable, then a scheme change request will be generated, which means that the overall structure of this subspace needs to be redesigned and adjusted. Then the local decoration material analysis is carried out to check the properties of the specific decoration materials used in the marked unsatisfactory part, including the type, quality, color, texture, and texture of the material. If the marked information reflects dissatisfaction with the local decoration materials, such as the color of the material does not match the overall style, or the quality of the material does not feel good enough, then a local material change request will be generated, that is, only the decoration materials of this part need to be replaced without changing the space structure.

Furthermore, the first recommended decoration plan generating module is used when the first user wears the VR connection device, including:

When the first user wears the VR connection device, the VR modeling platform is started to initialize the device; and the virtual environment is rendered based on the initialization result.

Specifically, after the first user wears the VR connection device, the VR modeling platform is started. At this time, the platform will first perform the initialization operation of the device. During the device initialization process, the platform will detect and calibrate the various parameters of the VR connection device, such as confirming whether the position tracking of the helmet is accurate, whether the operation response of the handle is sensitive, and whether the resolution and refresh rate of the display device are set correctly. At the same time, the software configuration related to the VR connection device will be checked to ensure that the system resources are reasonably allocated and the driver is running normally. Based on the results of the initialization, if the various parameters of the device meet the standards for normal operation, the VR modeling platform will start rendering the virtual environment. The rendering process includes constructing a realistic three-dimensional virtual space based on the existing decoration plan data, including the shape of the room, the style of furniture, the texture of the material, the effect of lighting, etc. Through fine rendering, users can make a judgment of satisfaction or not more quickly after wearing the VR connection device.
