[0038] The exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0039] Figure 1 is a flowchart of a method for generating a virtual environment in an exemplary embodiment of the present disclosure.

[0040] refer to Figure 1 , the virtual environment generation method 100 may include:

[0041] Step S1, obtaining topographic data of an environment to be restored, and forming a virtual topographic data of the environment to be restored in a virtual space according to the topographic data;

[0042] Step S2, obtaining laser dot matrix data of multiple acquisition targets of the environment to be restored, and reconstructing multiple virtual targets corresponding to the multiple acquisition targets on the virtual terrain through modeling according to the laser dot matrix data, wherein the multiple acquisition targets at least include buildings, roads, and fixed facilities;

[0043] Step S3, acquiring texture data and image data of the plurality of acquisition targets, and restoring the appearance of the plurality of virtual targets in the virtual space according to the texture data and image data to form a target virtual environment corresponding to the environment to be restored;

[0044] Step S4, in response to the user access message, presenting the target virtual environment to the accessing user in a stereoscopic visual manner through a virtual reality device.

[0045] The disclosed embodiments can form a target virtual environment corresponding to the environment to be restored by accurately modeling and reconstructing the environment to be restored in a virtual space based on the topographic data of the environment to be restored, laser dot data of multiple acquisition targets, texture data and image data, and then enable users to access the target virtual environment through virtual reality devices, thereby satisfying the users' needs for virtual tours of a specific target environment.

[0046] The method of the disclosed embodiment can be used to reproduce various environments to be restored, such as villages, communities, cities, and natural environments within a certain range, in a virtual space to form a target virtual environment, and allow users to visit the target virtual environment through virtual reality devices.

[0047] The method of the embodiment of the present disclosure can realize the data collection process when the environment to be restored does not disappear or change.

[0048] The method of the embodiment of the present disclosure may be automatically executed by a computer or manually executed.

[0049] Next, each step of the virtual environment generation method 100 is described in detail.

[0050] In step S1, the topographic data of the environment to be restored are obtained, and a virtual topographic data of the environment to be restored is formed in a virtual space according to the topographic data.

[0051] In the embodiments of the present disclosure, the environment to be restored includes but is not limited to villages, communities, cities, natural environments within a certain range (such as mountains, rivers), etc.

[0052] Topography refers to the physical shape, height and structure of the earth's surface, describing various features of the earth's surface, such as mountains, hills, plains, rivers, etc. Topography can be quantitatively described by indicators such as altitude, slope, and aspect. Landforms are terrain features caused by various geological, climatic and hydrological processes, including mountains, canyons, glaciers, wind-blown sand dunes, etc. Landforms can reflect the geological and geographical history of the earth's surface over a long period of time.

[0053] To obtain the topographic data of the environment to be restored, the regional information or watershed information corresponding to the environment to be restored can be systematically organized through a geographic information system (GIS) to form data such as geographical features, natural resource distribution, and environmental conditions, thereby forming topographic data based on these data.

[0054] For example, GIS can be used to collect topographic data of the area where the environment to be restored is located, such as terrain elevation, slope, and water system information, including the distribution of rivers, lakes, and wetlands. Secondly, GIS can also be used to integrate climate data of the environment to be restored, including meteorological information such as precipitation and temperature, as well as land use data, including different types of land use such as farmland, forests, and cities. Environmental quality data can also be integrated, such as soil type, water quality, etc. In addition, in GIS, topographic data can also include terrain elevation data, terrain slope data, landform type data, etc.

[0055] In some embodiments, the topographic data may also include real-time or historical geographic data of traditional villages and historical buildings that have been collected and stored in advance. When the real-time or historical geographic data of traditional villages and historical buildings that have been collected in advance are stored, these data may be integrated together to generate detailed maps, and these maps may present the overall picture of the geographic space and provide record data of the geographic space relationship.

[0056] In addition, the height information and geomorphic features of the terrain to be restored can be obtained through lidar scanning, satellite remote sensing data, digital elevation model (DEM), etc. to form topographic and geomorphic data.

[0057] After obtaining the topographic data, modeling can be performed in the virtual space to form a virtual topography of the environment to be restored.

[0058] First, the terrain data can be processed and edited, including smoothing, filling blank areas, adjusting proportions and other operations, so as to better meet the needs of the virtual space. Next, the virtual terrain is automatically constructed according to the imported terrain data. In some embodiments, in addition to automatically generating virtual terrain, the ups and downs and features of the terrain can also be simulated manually by adding, moving, stretching vertices and other operations. Finally, suitable material maps can be automatically added to the virtual terrain data to increase the sense of reality and visual effects. Suitable maps can be automatically determined or automatically generated according to terrain features and object types. In some embodiments, appropriate light and shadow and special effects can also be automatically set according to parameters such as time and weather to enhance the visual effects of the terrain. For example, elements such as sunlight, shadows, and fog effects can be automatically added according to real-time parameters such as time and weather set by the system to make the virtual terrain look more vivid and natural.

[0059] After the virtual topography is formed, the natural geographical environment of the environment to be restored is reproduced. Next, the human geographical environment of the environment to be restored is further constructed.

[0060] In step S2, laser dot matrix data of multiple acquisition targets of the environment to be restored are obtained, and multiple virtual targets corresponding to the multiple acquisition targets are reconstructed on the virtual terrain through modeling based on the laser dot matrix data. The multiple acquisition targets include at least buildings, roads, and fixed facilities.

[0061] In one embodiment, three-dimensional laser scanning technology can be used in advance to perform laser scanning to collect and store laser dot matrix information of the road network and buildings of the original site of the environment to be restored (such as a village), and automatically extract the data when generating the target virtual environment. The laser scanner can accurately measure the geometric shape and structure of the surface of an object and generate a large amount of point cloud data. Through high-precision laser scanning, it is possible to achieve a full-dimensional three-dimensional perception of the environment to be restored, capture the subtle details of every corner, and obtain the laser dot matrix data of the geographic space of the environment to be restored, including the shape, structure and overall topography of the building.

[0062] Next, three-dimensional laser scanning modeling and reconstruction technology can be used to generate multiple virtual targets corresponding to multiple collected objects in the environment to be restored.

[0063] In the disclosed embodiments, the collection objects may be buildings, roads, fixed facilities, etc., wherein fixed facilities are, for example, water wells, electric poles, stones, trash cans, community fitness facilities, fixed seats, etc., which are objects that do not move under normal circumstances. In some cases, the collection objects may also include non-fixed facilities such as animals and plants. The number of collection objects should be as large as possible, and the collected laser dot matrix data should be as detailed as possible, so as to better restore the environment to be restored in the virtual space.

[0064] When the acquisition object is a building, the laser dot matrix data can include not only the outer contour of the building, but also the internal structure of the building, such as doors, windows, furniture, stairs, etc.

[0065] When reconstructing a virtual target based on laser point cloud data, the point cloud data can be processed first, including denoising, filtering, alignment and other operations to ensure the accuracy and integrity of the data. Next, the three-dimensional model of the collected object is reconstructed based on the processed point cloud data. Surfaces or polygonal meshes can be created by connecting point cloud points to gradually reconstruct the shape and structure of the object. During the modeling process, details can be automatically added, surfaces can be modified, the smoothness of the surface can be adjusted, textures can be added, colors can be adjusted, etc. can be adjusted according to the properties of the collected object to enhance the visual effect of the model. In addition, the above process can also be achieved by manually operating the laser modeling software.

[0066] In the disclosed embodiment, the virtual target may be directly constructed in the virtual environment so as to restore the position of the virtual target most accurately.

[0067] In addition, each virtual target may be automatically constructed in external software according to the laser point cloud data, and then the virtual target file may be exported so as to reuse the virtual target later. In this case, when performing step S2, the virtual target file may be directly imported into the virtual space.

[0068] After the virtual target is formed in step S2, in order to make the restoration effect more realistic, the surface of the virtual target needs to be further processed.

[0069] In step S3, texture data and image data of the multiple acquisition targets are obtained, and the appearance of the multiple virtual targets is restored in the virtual space according to the texture data and image data to form a target virtual environment corresponding to the environment to be restored.

[0070] In some embodiments, acquiring texture data and image data may be acquiring orthophotos of the acquisition target at multiple angles through laser point cloud data and photography data.

[0071] In the embodiments of the present disclosure, image data includes but is not limited to 360-degree static images, 360-degree videos, panoramic images, and historical photos. Texture data can be obtained by analyzing image data or by three-dimensional scanning technology (such as laser scanning, structured light scanning, etc.). In addition, optical property information such as reflection, absorption, and scattering of the surface of an object can be obtained through sensors such as lidar and infrared cameras to reconstruct the texture and material information of the surface of the object. For some special objects, physical texture information of the surface of the object can also be obtained through tactile sensors, including roughness, hardness, surface morphology, etc., to simulate the texture and texture of the surface of the object.

[0072] In addition, RTK (Real-Time Kinematic) measurement and panoramic photography can be used to record the geographic coordinates and surrounding environment of villages and buildings, and combined with the entry of historical pictures and digital modeling technology (CAD, SU) to build technology to display the environment to be restored.

[0073] At this point, a target virtual environment corresponding to the environment to be restored is formed in the virtual space. The topography, natural scenery, buildings, roads, fixed facilities, etc. of the target virtual environment are highly similar to those of the environment to be restored.

[0074] Finally, set up access capabilities for the target virtual environment.

[0075] In step S4, in response to the user access message, the target virtual environment is presented to the accessing user in a stereoscopic visual manner through a virtual reality device.

[0076] Virtual reality devices include but are not limited to virtual reality glasses, virtual reality headsets, etc.

[0077] Through virtual reality (VR) technology, the environment to be restored is rebuilt in the virtual space, allowing users to personally experience the cultural heritage of the original village through a digital platform. By building a target virtual environment with 360-degree images or videos, users can roam freely in the virtual space and observe the restored buildings and scenery around them, meeting the needs of users to visit specific target environments.

[0078] In the disclosed embodiment, more humanistic factors may be added to the target virtual environment to make the target virtual environment closer to the real state of the environment to be restored.

[0079] In one embodiment, cultural and historical information of the environment to be restored can be obtained, and the cultural and historical information includes traditional handicrafts, folk cultural activities, historical events, etc. Then, the cultural and historical information is associated with the topographic data of the environment to be restored, the laser dot matrix data of multiple acquisition targets, the texture data and the image data in the database and stored.

[0080] The stored cultural and historical information that can be directly obtained can be collected in advance using a variety of methods, including but not limited to questionnaires, visits and other means to obtain information on the rich local traditional crafts, folk customs, cultural activities and community history. For example, by designing a questionnaire, systematically understand the residents' cognition and participation in traditional crafts and cultural activities. Or, by visiting community residents, gain an in-depth understanding of their daily lives and explore the inheritance and evolution of folk customs. Establish a full picture of community culture and capture the personal experiences and insights of residents. Finally, through comprehensive analysis of these data, cultural and historical information corresponding to the environment to be restored is formed and stored after sorting.

[0081] When storing data, the collected data can be systematically organized and archived, and the data can be formatted to ensure its consistency and readability. Next, the database stores a corresponding combination of data on the environment to be restored, covering multi-dimensional information such as the spatial structure of the building, the technical elements of traditional skills, and the time and place of community activities, to ensure efficient storage, rapid retrieval, and updating of data. By setting up appropriate indexes and tags, flexible retrieval of information in the database can be achieved, making it convenient for users to query according to different dimensions. In addition, by comprehensively integrating various types of data and building a rich and real digital database, cultural information can be recorded and passed on in a more comprehensive and three-dimensional way.

[0082] Figure 2 It is a sub-flow chart of step S4 in one embodiment of the present disclosure.

[0083] refer to Figure 2 In one embodiment, the cultural history information includes regional cultural history information corresponding to the regional coordinates of the environment to be restored, and step S4 includes:

[0084] Step S41, determining the virtual area currently visited by the visiting user according to the coordinates of the visiting user in the target virtual environment;

[0085] Step S42, after determining the area of ​​the environment to be restored corresponding to the virtual area, determine the regional cultural history information corresponding to the area of ​​the environment to be restored;

[0086] Step S43: Pushing regional cultural history information to visiting users in the target virtual environment.

[0087] In the database, cultural and historical information can be classified by region, and when cultural and historical information has a corresponding location, the regional cultural and historical information is recorded according to the regional coordinates. When a visiting user visits the area, the regional cultural and historical information is automatically pushed through animation, images, text and other methods.

[0088] Figure 3 It is a schematic diagram for displaying cultural and historical information in one embodiment of the present disclosure.

[0089] refer to Figure 3 , location A is a temple, and location B is a vegetable market. The coordinates of the visiting user in the virtual environment are monitored in real time to determine the virtual area where the visiting user is located. When the visiting user is determined to have visited the virtual location A according to the virtual area, the corresponding location A of the environment to be restored is determined according to the virtual location A, and the introduction of location A corresponding to the location A of the environment to be restored (regional cultural and historical information) is found. The introduction of location A can be automatically popped up next to the temple of the virtual location A, and the vegetable market B can be indicated by a brief text description. The above virtual area is defined by a coordinate range. For example, the coordinate range of the virtual location A can be (a≤x<b and c≤y<d), where x and y are coordinate variables, and a, b, c, and d are constants.

[0090] In addition to being used to display information, cultural and historical information can also be used to construct richer environmental elements.

[0091] In one embodiment, multiple non-player characters (NPCs) and virtual props can be set in the target virtual environment based on cultural and historical information. The multiple non-player characters operate the virtual props in the target virtual environment to restore at least one of traditional handicrafts, folk cultural activities, and historical events.

[0092] Figure 4 is a schematic diagram of a target virtual environment in one embodiment of the present disclosure.

[0093] refer to Figure 4 In one embodiment, a plurality of non-player characters 41 operate virtual props 42 in a specific area, such as a road, to reproduce a cultural activity. Figure 4 Taking acrobatics and sales activities as an example, in actual applications, non-player characters and virtual props can be automatically generated based on preset keywords mentioned in cultural and historical information (such as acrobatics, candied haws, etc.), and the actions of non-player characters and their positional relationship with virtual props can be automatically set according to the preset keywords, thereby restoring the activities corresponding to the preset keywords.

[0094] In addition, interactive functions can also be set up in the virtual environment.

[0095] In one embodiment, a virtual object corresponding to the accessing user may be set in the target virtual environment. The virtual object is controlled by the accessing user to move in the target virtual environment and interact with non-player characters and / or other virtual objects.

[0096] The interactive method can be that the visiting user actively interacts with the non-player characters and / or other virtual objects, and the non-player characters automatically generate reply actions and reply words based on the analysis of the visiting user's actions and language; in addition, the visiting user can also be invited to participate in humanistic activities with multiple non-player characters and / or other virtual objects.

[0097] Based on cultural and historical information, we can plan and build diversified online interactive channels, covering various forms, such as online cultural courses, virtual craft workshops, community cultural event calendars, etc., to stimulate and promote cultural exchanges among members of the immigrant community. Through online cultural courses, a platform is provided for community members to learn and share cultural knowledge. Virtual craft workshops provide opportunities to participate in practice and master craft skills. The community cultural event calendar covers a variety of activities, providing members with opportunities to participate, experience and interact. Strengthening the connection between community members, creating a richer cultural experience, and promoting a more comprehensive and in-depth realization of cultural inheritance and exchange.

[0098] The above-mentioned humanistic activities can be respectively set up in fixed activity venues. When a visiting user visits the target virtual environment, he can directly enter the activity venue of the humanistic activities to participate in the interaction, or he can push an activity invitation to the visiting user, and the visiting user can express his intention to participate by clicking an icon or other interactive methods, and the virtual object corresponding to the visiting user can be directly moved to the activity venue.

[0099] By establishing diversified online interactive channels, we can promote communication between users, increase user stickiness and improve user experience.

[0100] In some embodiments, smart navigation services can also be provided to users.

[0101] Figure 5 It is a sub-flow chart of step S4 in another embodiment of the present disclosure.

[0102] refer to Figure 5 In another embodiment, step S4 comprises:

[0103] Step S44, obtaining user information of the accessing user;

[0104] Step S45, determining the access preference of the access user according to the user information;

[0105] Step S46, generating a navigation route and / or access shortcut corresponding to the accessing user according to the access preference;

[0106] Step S47: Pushing a navigation route and / or a shortcut to the visiting user in the target virtual environment.

[0107] Figure 5 The illustrated embodiment may be referred to as an intelligent tour guide service.

[0108] The disclosed embodiments can provide users with personalized navigation services and make recommendations based on user interests and historical information. Based on big data processing, user interests and historical information are collected and analyzed. Through data such as user behavior, browsing history, and search preferences, a user profile is established to determine the user's access preferences, and personalized navigation recommendations are generated for each user based on the access preferences.

[0109] For example, if user A is determined to like rural scenery based on the user profile, a route map from user A's current location to the edge of the field is automatically generated to guide user A to the edge of the field. If user B likes to visit his original residence, the location coordinates of the original residence are obtained, and a shortcut to his original residence is pushed directly to user B, so that user B can directly visit his original residence through simple operations (such as clicking on the shortcut).

[0110] In addition, when there are multiple different target virtual environments, a target virtual environment can also be recommended to the user according to the access preference of the accessing user. Those skilled in the art can implement intelligent navigation in a target virtual environment or between multiple target virtual environments in a variety of ways, and the present disclosure does not impose any special restrictions on this.

[0111] By introducing the smart guide function, we can provide customized cultural experience based on user preferences and historical information, thereby increasing user stickiness and engagement.

[0112] The target virtual environment generated by the method of the embodiment of the present disclosure can be displayed through a network platform and can be accessed by users through the network platform. The target virtual environment can be used to reproduce the original address of the immigrant community, and allow immigrants to visit the original address in a virtual space and interact with other immigrants, meet the needs of immigrants to access a specific target environment, and solve the technical problem that users cannot access a specific environment. Therefore, it can effectively solve the dilemma of immigrants who cannot quickly establish new social relationships after relocation, lack a sense of belonging, and have difficulty integrating into the cultural inheritance and communication of the new environment, thereby improving the user experience.

[0113] Corresponding to the above method embodiments, the present disclosure further provides a virtual reality device on which data is stored, and the data is used to enable the virtual reality device to present a target virtual environment generated by the virtual environment generation method as described in any of the above items.
