Description

Technical Field

[0001] This invention relates to the field of virtual reality and 3D modeling technology, specifically to a method for constructing a virtual exhibition hall system, an exhibition system, and a storage medium. Background Technology

[0002] In recent years, with the rapid development of virtual reality (VR), augmented reality (AR), and 3D modeling technologies, virtual exhibition hall systems have been widely used in digital cultural exhibitions, online exhibitions, and education and training. Current mainstream technologies primarily rely on 3D engines such as WebGL and Unity3D to construct virtual environments, combined with a B / S architecture to enable user access, supporting basic model rendering and simple interactive functions. Some systems have introduced dynamic loading and lightweight model optimization technologies to improve terminal compatibility and operating efficiency. However, existing technologies still have significant limitations in terms of intelligent exhibition hall layout, interactive flexibility, and user experience optimization, making it difficult to meet the growing demand for high-quality, personalized exhibitions.

[0003] Existing virtual exhibition hall systems generally suffer from problems such as reliance on manual experience for layout planning, low space utilization, and difficulty in adapting to dynamic changes in the number of exhibits. This results in low efficiency in exhibition hall construction and limited scalability. In terms of model rendering, most systems lack multi-precision LOD structures and lighting baking mechanisms, failing to balance visual effects and device performance. This leads to lag on low-spec terminals, limited interaction methods, and a lack of cross-platform adaptability, making it difficult to meet the operating habits of different user groups. Furthermore, they generally lack mechanisms for collecting and analyzing user behavior data, making it impossible to achieve personalized recommendations and interaction optimization. At the same time, content updates require a complete system redeployment, resulting in high maintenance costs and long cycles. These problems severely restrict the practicality and scalability of virtual exhibition hall systems, necessitating a smart, efficient, and flexible construction method to address them. Summary of the Invention

[0004] In view of the above-mentioned problems, the present invention is proposed.

[0005] Therefore, the technical problem solved by this invention is that existing virtual exhibition hall technologies suffer from poor intelligence in layout planning, low cross-platform compatibility, insufficient interactive flexibility and user experience optimization, and the problem of how to efficiently construct a virtual exhibition hall model with intelligent interaction and low-cost maintenance.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a method for constructing a virtual exhibition hall system, comprising planning the layout of the exhibition hall according to the number of exhibits, constructing a three-dimensional virtual exhibition hall model; setting texture maps for each area of ​​the exhibition hall, and generating texture maps through lighting baking; setting exhibit locations and embedding display materials, constructing interactive logic and configuring interactive methods.

[0007] As a preferred embodiment of the construction method of the virtual exhibition hall system described in this invention, the construction of the three-dimensional virtual exhibition hall model includes: automatically counting the exhibits to be displayed using an exhibit database, the database source including the exhibit list uploaded by the curator, and automatically identifying the total number of exhibits through unique IDs or tags; according to preset spatial distribution rules, including per capita viewing area, exhibit spacing, flow smoothness, and visual transparency requirements, spatial partitioning of exhibits is performed using K-means clustering and spatial segmentation algorithms, dividing the exhibition hall into different logical areas, each area being adapted to a different number and type of exhibits; based on exhibit volume, theme classification, and the coherence of viewing paths, a preliminary layout sketch is generated; and the three-dimensional modeling tool Blender is called to automatically construct the virtual spatial geometric boundaries and structural supports of each area, forming the basic model of the three-dimensional virtual exhibition hall, including constructing the exhibition hall floor, walls, roof, and passage structure, and setting the size, material properties, and position information of each geometric object in the scene.

[0008] Collision objects are set up and passage is simulated. The spatial collision detection function is used to verify whether the visitor's movement path is unobstructed and whether the view is obstructed. The size and scale parameters of the 3D virtual exhibition hall are modeled according to the preset scale of the actual exhibits and saved as the first stage model of the 3D virtual exhibition hall.

[0010] As a preferred embodiment of the construction method of the virtual exhibition hall system described in this invention, wherein: 4. The step of generating texture models through light baking includes setting texture maps for each area based on immersion and visual guidance, the spatial functions of each area of ​​the exhibition hall and the needs of exhibit display; automatically filtering candidate texture sets according to the purpose of the exhibition hall area and the type of exhibits through a preset texture matching rule library; using a content-based image retrieval method to match texture maps that fit the visual style and exhibit attributes from the candidate textures; the textures include material textures and atmosphere guidance textures; combining a global illumination algorithm to perform high-quality lighting simulation on the model surface to generate basic UV coordinates and scene lighting distribution maps; and using a UV unwrapping algorithm. Texture coordinates are mapped onto the 3D mesh surface. The dynamic lighting results are pre-calculated into texture maps containing changes in light and shadow and shadow details through a baking algorithm. The texture maps of each region are rendered, and the parameters of texture brightness, roughness, and transparency are fine-tuned through shaders. Lighting points are set, and the main light source, auxiliary light source, and edge light source are configured using the three-point lighting method.

[0025] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the following description of the embodiments will be briefly introduced. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0026] Figure 1 The first embodiment of the present invention provides an overall flowchart of a method for constructing a virtual exhibition hall system.

[0027] Figure 2 The following is an overall flowchart of the construction system for a virtual exhibition hall system provided in the third embodiment of the present invention. Detailed Implementation

[0028] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] Example 1, referring to Figure 1 As an embodiment of the present invention, a method for constructing a virtual exhibition hall system is provided, comprising:

[0030] S1: Plan the exhibition hall layout based on the number of exhibits and construct a three-dimensional virtual exhibition hall model.

[0031] Furthermore, constructing a 3D virtual exhibition hall model involves automatically counting the exhibits to be displayed using an exhibit database. The database source includes exhibit lists uploaded by curators, and the total number of exhibits is automatically identified through unique IDs or tags. Based on preset spatial distribution rules, including per capita viewing area, exhibit spacing, flow smoothness, and visual transparency requirements, exhibits are spatially partitioned using K-means clustering and spatial segmentation algorithms. The exhibition hall is divided into different logical areas, each adapted to a different number and type of exhibits. Based on exhibit volume, theme classification, and the continuity of viewing paths, a preliminary layout sketch is generated. The 3D modeling tool Blender is then used to automatically construct the virtual spatial geometric boundaries and structural supports of each area, forming the basic model of the 3D virtual exhibition hall. This includes constructing the exhibition hall floor, walls, roof, and passageway structures, and setting the size, material properties, and position information of each geometric object in the scene.

[0032] Collision objects are set up and passage is simulated. The spatial collision detection function is used to verify whether the visitor's movement path is unobstructed and whether the view is obstructed. The size and scale parameters of the 3D virtual exhibition hall are modeled according to the preset scale of the actual exhibits and saved as the first stage model of the 3D virtual exhibition hall.

[0033] It should be noted that building a 3D virtual exhibition hall model also includes generating 3D spatial versions of the virtual exhibition hall with different levels of precision. Each version is configured with LOD rules, and the 3D spatial versions of the virtual exhibition hall with different levels of precision are dynamically loaded according to the performance indicators of the terminal device, including GPU performance, memory threshold and network bandwidth.

[0034] The 3D space of virtual exhibition halls with different precisions is exported using a WebGL-compatible format, while preserving the UV unwrapping structure and spatial coordinate information.

[0035] It should also be noted that the intelligent planning of the exhibition hall layout is achieved through automatic statistics of the exhibit database and spatial distribution rule algorithms, which solves the problems of low efficiency and insufficient space utilization of manual layout. Based on K-means clustering and circulation simulation algorithms, a 3D model that meets the requirements of per capita browsing area, exhibit spacing and visual transparency is automatically generated, improving the efficiency of space optimization. The multi-precision LOD version design adapts to the performance requirements of different terminals, ensuring that the high-fidelity model runs smoothly on low-end devices, reducing the hardware threshold. The collision body setting and path verification functions ensure unobstructed virtual circulation, providing a reliable foundation for subsequent interaction.

[0036] S2: Set texture maps for each area of ​​the exhibition hall and generate texture models through lighting baking.

[0037] Furthermore, the process of generating texture models through light baking involves setting texture maps for each area based on immersion and visual guidance, the spatial functions of each area in the exhibition hall, and the needs of exhibit display. According to the purpose of each area and the type of exhibit, a set of candidate textures is automatically filtered using a pre-defined texture matching rule library. A content-based image retrieval method is then used to match texture maps that match the visual style and exhibit attributes from the candidate textures. These textures include material textures and atmosphere-guiding textures. A global illumination algorithm is then used to perform high-quality lighting simulation on the model surface, generating basic UV coordinates and scene lighting distribution maps. Finally, a UV unwrapping algorithm is used to map the texture coordinates onto the 3D mesh surface. The dynamic lighting results are pre-calculated into texture maps containing changes in light and shadow and shadow details through a baking algorithm. The texture maps of each region are rendered, and the parameters of texture brightness, roughness, and transparency are fine-tuned through shaders. The lighting points are set, and the main light source, auxiliary light source, and edge light source are configured using the three-point lighting method. The illuminance value, attenuation radius, direction vector, and projection angle of each light source are set to generate a high-fidelity light map. The texture and light map are merged and output as a texture set file, which is then bound to the first-stage model of the 3D virtual exhibition hall. The second-stage model of the 3D virtual exhibition hall is generated by automatically matching and mapping the model's face index and UV coordinates.

[0038] It should be noted that by using light baking and texture optimization techniques, a balance between visual realism and rendering performance is achieved. By simulating real light reflection, exhibits in the virtual environment present a texture close to that of real objects. Image pyramid compression technology generates dual-version materials, prioritizing the display of the low-resolution preview image during loading. Lightmap pre-calculation reduces the pressure of real-time rendering, enabling even low-end and mid-range devices to stably run high-fidelity scenes. At the same time, UV unwrapping and normal mapping techniques enhance detail, providing an immersive visual foundation for subsequent interactions and improving user experience satisfaction.

[0039] S3: Set the location of exhibits and embed display materials, build interactive logic and configure interactive methods.

[0040] Furthermore, setting exhibit locations and embedding display materials includes conducting visibility analysis of the exhibition space based on the second-stage model of the 3D virtual exhibition hall. This involves setting camera viewpoints and visible area ranges, and using ray detection algorithms to detect whether the line of sight in each area is obstructed.

[0041] Adjust the location of exhibits, prioritizing unobstructed and visually accessible areas.

[0042] The exhibit locations are sorted according to the order of viewing, and each location is assigned a unique number, spatial coordinates, and orientation vector.

[0043] The image materials are compressed to improve image clarity. An image pyramid compression algorithm is used to generate the first compressed material, and a mapping relationship is established between the first high-definition original image material and the first high-definition original image material in the database. The mapping data includes the point number, the original image path, the compressed image path, and the display size.

[0044] By embedding the location number and material binding information into the metadata structure of the 3D virtual exhibition hall model, the third-stage model of the 3D virtual exhibition hall is generated.

[0045] It should also be noted that building the interaction logic and configuring the interaction method includes encapsulating the display image materials, point numbers and material binding information and interaction logic of the 3D virtual exhibition hall model into a deployment package based on the third-stage model of the 3D virtual exhibition hall. The deployment package includes a responsive UI component library, which automatically adapts the size of the interactive buttons, the layout of the display area, the scrolling behavior and the loading mode according to the type of terminal device.

[0046] For mobile devices, touch adaptation logic is provided, including swipe switching, two-finger zoom and long press interaction operations. Users can click on the first compressed material of the exhibit point in the model to trigger the loading of the first high-definition original image material and the synchronously associated exhibit introduction. Users can select the exhibit number in the navigation interface to view them in sequence. When viewing the first high-definition original image material page, users can click the "Previous / Next" button to switch the displayed content in numerical order.

[0047] For PC devices, mouse events and shortcut keys are used to map and control the switching and display of materials, and a lazy loading mechanism is enabled to load the corresponding resources when the user enters the interaction radius.

[0048] It should also be noted that building the interaction logic and configuring the interaction methods also includes supporting the selection and activation of the configuration interface for each interaction mode. Administrators can enable any one or more combinations of interaction methods through the backend configuration panel, automatically record user interaction behavior and generate access logs, analyze and recommend optimizations based on user browsing behavior, and the interaction function runs in the WebGL and Unity engine environment, supports hot updates and remote content replacement mechanisms, supports cross-platform compatibility, and maintains consistent response during operation.

[0049] It should also be noted that by encapsulating interaction logic and using a responsive UI component library, cross-platform adaptation and user behavior data-driven optimization are achieved. The terminal device automatic recognition mechanism dynamically adjusts the interaction method (such as mobile touch operation and PC shortcut key mapping) to reduce the operation error rate. The administrator backend can flexibly configure interaction combinations (such as long press to view details and two-finger zoom) to meet diverse needs. User behavior log analysis triggers recommendation algorithms to optimize exhibit sorting, which helps to increase the average viewing time. Hot update and remote content replacement mechanisms support real-time maintenance and effectively reduce operating costs. At the same time, the compatibility of WebGL and Unity dual engines ensures operational consistency and improves system scalability and lifecycle.
