Description

Technical Field

[0001] The present invention relates to the field of virtual reality hardware equipment and three-dimensional visualization technology, and in particular to a VR visualization interaction device and an interaction method for an underground space layout solution. Background Art

[0002] At present, the main method of underground space layout design still relies on traditional two-dimensional drawings and simple three-dimensional rendering technology. As the basis of engineering design, two-dimensional drawings can provide accurate spatial dimensions and layout information, but their planar expression method limits the intuitive understanding of spatial structure and layout by designers and project stakeholders. Although simple three-dimensional rendering technology has improved this problem to a certain extent by generating three-dimensional models to show spatial effects, this method still has significant shortcomings in complex underground space design. Especially in complex underground projects, such as subway stations, underground comprehensive transportation hubs, etc., traditional design methods often find it difficult to intuitively show the sense of scale of the space, and the design efficiency and solution quality are therefore limited.

[0003] Although virtual reality (VR) technology has been gradually applied in the field of architectural design in recent years, with the help of VR equipment, designers can feel the design space more intuitively and perform a certain degree of interactive operations. Existing VR visualization systems have many shortcomings when applied to underground space layout design. First, these systems usually fail to fully consider the special needs of underground space, such as complex geometry, limited natural light, and design requirements for ventilation and drainage systems, resulting in the inability to accurately reproduce these key environmental factors when simulating underground space. Secondly, when rendering underground space, existing VR systems often lack real immersion and interactivity, making it difficult for designers to intuitively feel and evaluate the actual layout and proportional relationship of the space through virtual reality. These shortcomings are particularly evident in complex underground projects. Existing technologies cannot effectively show the sense of scale of the space, nor do they support real-time design modifications and multi-person collaboration, which seriously affects the design efficiency and the quality of the solution. How to achieve real-time interaction while ensuring high-quality rendering, and how to ensure the smoothness and accuracy of the VR experience are still key issues that are difficult to solve with existing technologies. These defects make underground space layout design face many challenges in practical applications, and improvement and innovation are urgently needed. Summary of the invention

[0004] In view of the shortcomings of the existing technology, the present invention proposes a VR visualization interaction device and interaction method for underground space layout schemes, aiming to overcome the defects of current design methods in intuitiveness, interactivity and multi-user collaboration capabilities.

In addition, the deep integration of the present device with commonly used design software enables designers to work in a familiar tool environment while enjoying the unique advantages brought by VR visualization.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention belong to the present invention.

[0045] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0046] See also Figure 1-6 , this embodiment provides a VR visualization interactive device for underground space layout scheme, including a three-dimensional graphics processing unit and a virtual reality interactive terminal that interacts with the three-dimensional graphics processing unit, a design software synchronization interface, and a collaborative design communication module. The three-dimensional graphics processing unit is the core computing component of the device. It uses a high-performance graphics processor and a dedicated graphics acceleration chip to quickly convert the two-dimensional plane layout data of the underground space into a realistic three-dimensional space model and perform real-time rendering. Through this process, designers can directly generate a three-dimensional model from a two-dimensional drawing, greatly improving the intuitiveness and accuracy of the design.

[0047] The virtual reality interactive terminal is a direct interactive interface between the user and the 3D graphics processing unit. As the main entrance to the user experience, the virtual reality interactive terminal is equipped with a high-resolution display device and a motion capture system to ensure that the user can immerse himself in the virtual environment and interact with the 3D model in real time. The interactive terminal is seamlessly integrated with the 3D graphics processing unit through a low-latency wireless transmission module, supporting users to interact naturally in a simulated underground environment. Every operation of the user can be quickly transmitted and fed back, thus achieving a smooth operating experience. This low-latency wireless transmission allows designers to operate in a virtual environment without worrying about screen freezes or insensitive operations caused by delays, ensuring efficient design work.

[0048] The design software synchronization interface is used to realize data exchange with external design software. The high-speed data conversion processor of this interface can capture and synchronize the changes in the external design software, and transmit these changes to the 3D graphics processing unit in real time to meet the frequent adjustment and optimization needs in the underground space design process. Through this interface, designers can design in familiar CAD software, and these design changes can be immediately reflected in the virtual reality environment, greatly improving the real-time and collaborative nature of the design. The multi-protocol communication module of the design software synchronization interface supports the compatibility of multiple mainstream design software, making this device widely used in various underground space layout design scenarios.

[0049] The collaborative design communication module is used to support real-time collaboration and communication among multiple users in a virtual environment, synchronously handle complex underground layout projects, and ensure that multiple designers can work synchronously in the same virtual space. This module ensures real-time synchronization of the positions of all users through a virtual coordinate synchronization unit, and supports highlighting and instant sharing of design points through a design mark synchronizer. These features enable team members to easily exchange opinions and provide instant feedback in a virtual environment, greatly improving the collaborative efficiency and solution quality of complex underground space layout design.

[0050] Please refer to Figure 3, the 3D graphics processing unit also includes a ray tracing processor and a texture mapping accelerator. The role of the ray tracing processor is to achieve realistic lighting effects by simulating the propagation path of light sources in 3D space. In the design of underground space, the authenticity of the lighting effect directly affects the accuracy of the designer's perception of space. Through the ray tracing processor, the system can simulate a variety of lighting scenes including direct lighting, indirect lighting and shadow effects, allowing designers to truly observe the reflection, refraction and shadow changes of light on different materials and structures in a virtual environment, so as to more accurately evaluate the feasibility of the design scheme. The texture mapping accelerator is responsible for quickly applying the surface texture in the preset material library to the 3D model. The surface characteristics of different materials in the underground space, such as the roughness of concrete and the reflective characteristics of metal, can be quickly displayed in the model through the texture mapping accelerator, which not only improves the realism of the model, but also greatly improves the efficiency of rendering, allowing designers to complete complex material applications and adjustments in a short time, helping them to more intuitively foresee the final design effect.

[0051] Specifically, the 3D graphics processing unit can be configured with an Intel Core i7 processor, an NVIDIA RTX 3060 graphics card, 16GB RAM, and a 512GB SSD. The Intel Core i7 processor provides powerful computing power to ensure the efficiency of multi-threaded task processing; the NVIDIA RTX 3060 graphics card integrates a dedicated ray tracing and texture acceleration hardware unit, which can greatly improve the speed and quality of 3D rendering; 16GB of RAM provides sufficient memory resources to ensure smooth processing of large 3D models; the 512GB SSD not only speeds up data reading, but also provides sufficient space for the storage of complex design files. This hardware configuration can effectively support the complex rendering and real-time interaction requirements of underground space layout, ensuring the efficiency of the entire design process.

[0052] See also Figure 4, the virtual reality interactive terminal is a direct interface for user experience, providing users with an immersive and highly interactive design environment. It consists of a high-resolution VR headset and a motion capture system. The VR headset uses a display system with a wide field of view and high angular resolution. Specifically, it can use dual 4K resolution OLED micro displays and is equipped with a dedicated optical system. This configuration not only provides clear and delicate image quality, but also ensures a wide field of view of 120°. Users can obtain an extremely wide and distortion-free field of view in the virtual environment, further enhancing the sense of space and presence. VR headsets can use mature high-end products on the market, such as HTC VIVE Pro 2 or Varjo XR-3. These devices not only provide high-resolution display effects, but also have a wide field of view and excellent color performance, which can meet the high requirements of visual accuracy for complex underground space design. The motion capture system can use a handle to operate the device or a Vientiane treadmill, such as OmniVR and KatVR. The choice of these devices provides users with flexible interaction methods. Through the operation of the handle, users can naturally perform various design operations in the virtual environment, such as selection, dragging and scaling, while the Vientiane treadmill allows users to move in the virtual space by walking or running, as if they were actually there, helping designers better understand and explore the complex structure and layout of the underground space layout. This natural and intuitive interaction method significantly improves the user's understanding and evaluation efficiency of the design plan.

[0053] In addition, the virtual reality interactive terminal can also be equipped with a tactile feedback controller. Through the precision linear resonant actuator and pressure sensor array, users can feel the real touch of different materials, such as the roughness of concrete or the cold touch of metal. Tactile feedback not only enhances the user's immersion in the virtual environment, but also enables users to more accurately perceive the selection and effect of materials in the design. These hardware components are tightly integrated with the 3D graphics processing unit through a low-latency wireless transmission module, ensuring that the user's operations in the virtual environment can be responded to in real time and smoothly, so that every modification and adjustment in the design process can be reflected in the virtual space immediately, greatly improving the fluency and efficiency of the design work.

[0054] See also Figure 5, the design software synchronization interface includes a high-speed data conversion processor and a multi-protocol communication module. The function of the high-speed data conversion processor is to capture real-time modifications in external design software and instantly convert these modified data into a data format suitable for the 3D graphics processing unit. The purpose of this processor is to ensure that when designers make design modifications in external design software such as AutoCAD, Rhino or various BIM tools, the data can be quickly captured and accurately converted, thereby achieving seamless real-time synchronization. Through this process, the 3D model seen by the designer in the virtual reality environment can be consistent with the design changes in the external software, thereby improving the real-time and accuracy of the design. The multi-protocol communication module supports a variety of high-speed data transmission standards to ensure compatibility and low-latency data exchange with different design software. This module is compatible with a variety of communication standards including USB 3.1, Thunderbolt 3 and 10Gb Ethernet, thereby meeting the connection requirements of different external design software and hardware platforms. Through these high-speed transmission standards, designers can get a fast and stable connection experience when exchanging data between different software and devices, avoiding the problem of inefficient design caused by data transmission delays or incompatibility.

[0055] This design software synchronization interface enables the entire system to interact with data in an efficient and real-time manner when dealing with complex underground space layout designs, ensuring that the model in the virtual environment can quickly respond to external design modifications, while also ensuring broad compatibility with a variety of design tools, providing designers with an efficient and flexible design platform. This platform not only improves the fluency of design work, but also greatly enhances the adaptability of the system, allowing it to play a role in various complex underground space design projects.

[0056] See also Figure 6The collaborative design communication module includes a virtual coordinate synchronization unit, a design mark synchronizer, a high-performance audio processing chip and a spatial audio array, and a network synchronization processor. These hardware can be integrated through a central collaborative processor. The main function of the virtual coordinate synchronization unit is to ensure that the positions of multiple users in the virtual environment can be synchronized in real time. This means that no matter where the team members are, their positions in the virtual space can be accurately and instantly reflected in the vision of other members, thereby achieving more smooth and coordinated collaboration. This synchronization mechanism is particularly suitable for multi-person collaboration scenarios in complex underground space design, ensuring that all participants' understanding and operation of the design are always in the same spatial reference system, effectively avoiding operational conflicts or misunderstandings caused by asynchronous positions. The design mark synchronizer is used to support real-time sharing and highlighting of design marks in a virtual environment. Through this function, team members can mark on the virtual model and immediately synchronize these marks to other users. For example, when a designer marks a key structure in an underground space, all other participants can immediately see the mark and can discuss or further operate around it. This function greatly improves the efficiency of team collaboration and makes the discussion and modification process of complex design solutions more intuitive and interactive. The high-performance audio processing chip and spatial audio array are designed to provide high-quality voice communication and achieve directional sound restoration. In the collaborative design process, clear voice communication is essential. Through the spatial audio array, users can not only hear clear voice, but also feel the directionality of the sound. This design enhances the user's immersion in the virtual environment, as if each speaker is in their actual position, thereby further improving the realism and interactivity of the collaborative experience. Finally, the network synchronization processor uses a special acceleration algorithm to minimize data transmission delays and ensure that all users always see the same content in the virtual environment. In multi-user collaborative design, data transmission delays may cause inconsistencies in the scenes seen by different users, affecting the efficiency of team collaboration. Through the acceleration algorithm of the network synchronization processor, the system can quickly transmit and synchronize data, so that each user's virtual environment can maintain a consistent state, thereby ensuring the smooth progress of design discussions and operations, and avoiding the trouble caused by data asynchrony. This combined design enables the collaborative design communication module to provide efficient and stable multi-user collaboration support in a virtual reality environment, which is a key component to ensure the success of complex underground space design projects.

[0057] See also Figure 7 Another embodiment of the present invention describes an interactive method based on the above-mentioned VR visualization interactive device for underground space layout scheme, and the interactive method comprises the following steps:

[0058] S1, creates 2D layout data in external design software and transmits the data to the 3D graphics processing unit through the design software synchronization interface. Designers usually use AutoCAD, Rhino or other BIM tools to generate these 2D data. The accuracy and timeliness of data transmission are the basis for ensuring the smooth progress of the design. The 3D graphics processing unit optimizes the feature processing capabilities suitable for underground space, especially when dealing with complex geometric shapes, hierarchical relationships, lighting conditions and ventilation systems in underground space, and has efficient data conversion and processing capabilities.

[0059] S2, through the 3D graphics processing unit, converts the 2D data into a 3D space model and renders it in the virtual reality interactive terminal. This process uses high-performance graphics processors and graphics acceleration chips to quickly convert the 2D plane layout data into a three-dimensional 3D model, which can accurately simulate the special environmental conditions of underground space, such as light refraction, shadow processing, material reflection characteristics, and the multi-level layout structure of the space, so that the rendered 3D model is more in line with the characteristics of the actual underground space, providing designers with an intuitive and immersive evaluation platform to help them understand the structure and layout of the design plan more clearly.

[0060] S3, using the virtual reality interactive terminal, users enter the virtual environment, interact with the three-dimensional space model, and check and evaluate the design plan. In this stage, designers can roam freely in the virtual space, interact with the three-dimensional model through handles, treadmills and other equipment, simulate various scenes and conditions, and comprehensively evaluate the feasibility and rationality of the design. This interactive method improves the accuracy of the design, allowing designers to more realistically feel the physical characteristics and spatial sense of the underground space, and enables designers to quickly discover and correct potential problems in the design.

[0061] S4, through the collaborative design communication module in the virtual environment, realizes real-time collaboration and communication between multiple users, and marks, discusses and modifies the design plan. Through the collaborative design communication module, multiple designers or project stakeholders can enter the same virtual space at the same time for real-time communication and collaboration. All operations can be synchronized to other users in real time, so as to quickly reach a consensus and improve the speed and quality of the design plan. The collaborative design communication module is specially designed with data security and privacy protection functions. Through encrypted communication and access control mechanisms, it ensures that the security of design data and user privacy are fully protected during the multi-user collaboration process.

[0062] S5, synchronizes the design changes made in the virtual environment back to the external design software, achieving real-time feedback and optimization of the design process. Through this closed-loop design process, all adjustments made by the designer in the virtual environment can be accurately reflected in the original design file, avoiding data loss or information inconsistency, and significantly improving the design quality and efficiency of the underground space layout plan. The synchronization process integrates security protocols to ensure that data is not tampered with or leaked during transmission and synchronization, thereby ensuring the integrity and confidentiality of the design data.

[0063] Furthermore, in step S4, a multiple-cycle update function is included to support real-time synchronization of each user's design changes during multi-user collaboration. With this function, when any user modifies the three-dimensional space model in the virtual environment, the modification will be immediately captured by the system and transmitted to all other participating users. This real-time synchronization mechanism ensures that everyone in the design team can see the latest design changes at the same time, no matter where they are or what device they are using. At the same time, the system will accurately reflect these modifications in the updated three-dimensional space model, so that all users can see the same content in the virtual environment. This consistency and real-time performance not only improves the efficiency of collaboration, but also effectively avoids misunderstandings and design conflicts caused by information asymmetry or delays.

[0064] Taking the subway station as an example, as a public transportation hub with complex functions and huge structure, the design of the subway station needs to consider many factors, such as passenger flow lines, emergency evacuation routes, commercial space configuration, equipment room layout, ventilation and drainage systems, etc. These factors are highly integrated in space, which places extremely high demands on the accuracy and rationality of the design. The designer first uses external design software (such as AutoCAD, Rhino or BIM tools) to create the two-dimensional plane layout data of the subway station. These data include the preliminary configuration of each functional area, the location of passages and entrances and exits, the layout of the equipment room, the arrangement of public facilities, etc. Through the design software synchronization interface, these two-dimensional plane data are transmitted in real time to the three-dimensional graphics processing unit in the VR visualization interactive device of the underground space layout scheme of the present invention. The three-dimensional graphics processing unit converts the received two-dimensional data into a three-dimensional space model and performs realistic real-time rendering in the virtual reality interactive terminal. After wearing a high-resolution VR headset, the designer can enter the virtual environment of the subway station and explore the entire underground space immersively. Designers can freely walk around different areas of the subway station, view the layout of each functional area, evaluate the rationality of passenger flow lines, and perform detailed operations through the motion capture system, such as adjusting the platform width and optimizing the placement of escalators and elevators. In the virtual environment, designers can collaborate with other stakeholders of the project (such as transportation planners, fire experts, and construction engineers) in real time through the collaborative design communication module. Team members can enter the virtual subway station at the same time, view the current design plan, and mark and discuss key areas, such as whether the evacuation path of passengers is unobstructed, whether the layout of the equipment room is reasonable, and whether the configuration of the commercial area meets the needs of passenger flow. If it is found during the discussion that the design plan needs to be adjusted, such as the need to reconfigure the distribution of shops in the commercial area, the designer can immediately modify it in the virtual environment. These modifications are transmitted back to the external design software in real time through the system's design software synchronization interface to ensure that all design adjustments can be accurately reflected in the original design file. Through this closed-loop design process, the VR visualization interactive device for underground space layout schemes of the present invention not only improves the efficiency of subway station design, but also ensures the rationality and executability of the design scheme. In practical applications, this method can significantly shorten the design cycle, reduce the risk of rework due to design omissions, and ultimately achieve efficient planning and construction of underground space in subway stations.

[0065] In summary, the present invention provides a VR visualization interactive device and interactive method for underground space layout schemes, which realizes rapid visualization, real-time interaction and multi-user collaboration of underground space layout by combining high-performance hardware with special software. The device not only improves the accuracy of space perception, enabling designers to grasp the scale and proportional relationship of the space more intuitively, but also significantly improves the design efficiency and collaboration effect through real-time interaction functions and multiple cycle update functions. The deep integration of the device of the present invention with commonly used design software makes the design process smoother and more optimized, and better meets the needs of modern complex underground space design projects. Overall, the present invention provides innovative technical support and solutions for the planning and design of underground space. Through the innovative combination of these hardware components, rapid visualization and interactive operation of underground space layout schemes are realized. It is suitable for the design stage of complex underground spaces such as subway stations, underground comprehensive transportation hubs, and underground commercial spaces, and can significantly improve design efficiency and scheme quality.
