The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0041] Those skilled in the art will understand that Figure 1The structure shown in the figure does not constitute a limitation on the smart device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange components differently. Preferably, the smart device can be a field display device of the earth exhibition hall, and an interactive device 1003 is set in the exhibition hall; the processor 1001, the communication bus 1002, the network interface 1004, and the memory 1005 are set on the server. The network interface 1004 can be used to transmit data obtained by a drone or an image acquisition device. In addition, the smart device can also be a mobile phone, a tablet, smart glasses, etc.

[0042] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a data storage module, a network communication module, a user interface module, and a city future plan land display experience program.

[0043] exist Figure 1 In the smart device shown, the network interface 1004 is mainly used for data communication with other devices; the interactive device 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the smart device of the present invention can be set in the smart device, and the smart device calls the city future plan earth display experience program stored in the memory 1005 through the processor 1001, and executes the city future plan earth display experience method provided by the embodiment of the present invention.

[0044] In the first embodiment of the present invention, a system for displaying and experiencing a city future plan is provided. In this embodiment, the system for displaying and experiencing a city future plan comprises:

[0045] A mapping module is used to obtain point cloud data and image data of the target scene in the target city;

[0046] An integration module, configured to generate a city data set according to the point cloud data, the image data and the city data of the target city;

[0047] An algorithm reconstruction module, used to generate a virtual city model corresponding to the target city according to the city data set, the preset city model and the optimization algorithm;

[0048] The interactive matching module is used to generate corresponding interactive information according to the terminal parameters of the terminal device and the virtual city model.

[0049] The mapping module here may include a data acquisition device and may also include a data reading device, which is not limited in the present embodiment. Generally, the mapping module here is used to collect point cloud data and image data and pre-process the point cloud data and the image data. Of course, in some embodiments, it can also be obtained by reading the stored data. The integration module here is used to integrate multiple different types of data. Specifically, the city data here can be multiple dimensions and multiple types of data. In the present embodiment, the city data includes pedestrian flow data, traffic data, environmental data, etc. In addition, in the present embodiment, the city data set here can be classified and stored according to the target scene. The first embodiment of the city future plan earth display experience system can refer to Figure 2 , Figure 2The specific implementation path diagram of the embodiment of the present invention for constructing a virtual city model; in addition, it should be noted that in this embodiment, the preset city model is a city information model (CIM). By mapping the data of the city data set to the city information model, since the data required by the preset city model and the city data set may be different, it is optional to manually perform default annotation and correction for abnormal values. In addition, in order to save computing resources and storage resources. It is necessary to optimize the preset model after the step of mapping the data of the city data set to the city information model to obtain the virtual city model. Specifically, the degree of optimization required can be determined according to the data of the city data set. In this embodiment, the specific degree of optimization required can be performed according to the following steps: by obtaining the minimum granularity of each data type in the target scene of the target city, a plurality of the minimum granularities corresponding to different data types are obtained, and the plurality of the minimum granularities are sorted, and the highest of the plurality of the minimum granularities is determined as the target granularity, and the simplification requirements are determined based on the target granularity. The target granularity here is the minimum unit distance, such as 100 meters, 200 meters, 500 meters and 1 kilometer. In addition, it should be noted that, for example, road data may only include traffic information of roads longer than 100 meters, and traffic data of buildings exceeding a preset area or space. For example, large communities, shopping malls, and office buildings. In this embodiment, it should be noted that the above-mentioned data is only the specific data of the virtual city model, and the virtual city model needs to be displayed in front of the user by rendering. Specifically, the virtual city model is imported into the Unity platform and rendered in the Unity platform. In the interactive matching module, the interactive information includes image data, and may also include information such as sound. The parameters set in the rendering process are determined by obtaining the terminal parameters of the terminal device, where the parameters include the specific positioning of the rendered scene, the complexity of the model, the instructions of the texture, the lighting, the shadow, the resolution, the frame rate, and the type of the rendering algorithm. The quality of the image can be adjusted by calling the built-in rendering pipeline, the universal rendering pipeline, the light map, the delayed lighting, and the like.

[0050] In this embodiment, by setting a mapping module, an integration module, an algorithm reconstruction module and an interactive matching module, and acquiring point cloud data and image data of a target scene of a target city, the spatial data and non-spatial data of a complete city can be obtained, and a city data set is generated according to the point cloud data, the image data and the city data of the target city, so that the point cloud data, the image data and the city data of the target city can be efficiently combined, which is beneficial to the efficiency of subsequent generation of a virtual city model; a virtual city model corresponding to the target city is generated through the city data set, a preset city model and an optimization algorithm, so that the obtained virtual city model is more efficient, and after generating corresponding interactive information according to the terminal parameters of the terminal device and the virtual city model, the virtual city model can be accurately and efficiently displayed, thereby optimizing the form of city data display and improving the city data display effect.

[0051] Further, based on the first embodiment, a second embodiment of the urban future plan land display experience system of the present invention is proposed. In this embodiment, the mapping module includes:

[0052] A scanning unit, used to control the UAV and a scanning radar arranged on the UAV to acquire the point cloud data of the target scene;

[0053] The shooting unit is used to control the shooting component to obtain the image data of the target scene according to a preset process.

[0054] The drone here can use a DJI drone, and a three-dimensional model is constructed based on the DJI Zhitu, the point cloud data and the image data. It should be noted that the three-dimensional scheme constructed here can be interactively modified by the relevant construction planning bureau and designers, and the scheme can also be simulated based on the three-dimensional model. In this embodiment, setting different types of units can improve the accuracy of the acquired point cloud data and image data, thereby increasing the amount of data, and further improving the accuracy of the virtual city model.

[0055] Furthermore, the urban future plan land display experience system also includes:

[0056] The calibration module is used to import the virtual city model into the target platform and calibrate the virtual city model according to the parameters based on the target platform, and the target platform is the Metacity platform. The Metacity platform here is a co-creation virtual world platform in cooperation with Filecoin. Filecoin is a decentralized storage network.

[0057] In this embodiment, it should be noted that since there are multiple different virtual city models, the virtual city model needs to be calibrated first after being uploaded to the Metacity platform. Specifically, the accuracy of the display is ensured through real space calibration.

[0058] Furthermore, the urban future plan land display experience system also includes:

[0059] The virtual positioning module determines the position parameters of the user during the interaction process according to the visual positioning service of the terminal device and the global positioning system, and the position parameters are used as the terminal parameters.

[0060] In this embodiment, since the interactive device is a smart device, it often includes an information collection device and a display device. The information collection device may include a camera and a sensor. For example, pressure sensors and micro cameras may be provided in AR glasses, and GPS, cameras, vibration sensors and other devices may be provided in mobile phones. In this embodiment, by obtaining the Visual Positioning Service (VPS) and the global positioning system executed by the terminal device, it is possible to determine the accurate mapping to the corresponding position in the virtual space, thereby improving the authenticity of the interaction. In addition, the preset position in the virtual space can be marked, so that the corresponding scene can be directly loaded through the preset position. Reference Figure 3 , Figure 3 This is an example of precise positioning and navigation in a virtual scene based on visual positioning services and global positioning system mapping. Optionally, it can also be quickly displayed through the satellite inertial vision system platform. The satellite inertial vision system refers to a positioning system that integrates satellite navigation, inertial navigation and visual navigation systems. In the visual positioning service, the image captured by the camera is matched with the database of known virtual city models to determine the specific virtual location in the virtual city model displayed by the user.

[0061] Furthermore, in this embodiment, the urban future plan land display experience system further includes:

[0062] The display module is used to import the virtual city model into a display rendering platform, and display the virtual city model according to the display rendering platform, wherein the display rendering platform is a Unity platform.

[0063] In this embodiment, Unity supports different types of rendering methods, which can effectively render the virtual city model. By rendering the virtual city model, the future new district can be displayed. Figure 4 , Figure 4This is a display effect diagram of the overall planning of the virtual city model of the present invention in the planning prediction and comparison of the earth exhibition hall; it should be noted that the earth plan in the embodiment can include the earth agency planning and the earth investment plan comparison. By accurately displaying, it can drive government investment, corporate investment, and social investment. Figure 5 and Figure 6 , Figure 5 It is a display effect diagram of the virtual city model of the present invention in the land exhibition hall planning prediction and comparison land price preview; Figure 6 This is a display effect diagram of the virtual city model of the present invention in the land exhibition hall for enterprise land selection and selection demonstration; since this virtual city model can be displayed on smart devices commonly used by the public, it can drive popularity, and simulate, promote, detect traffic flow, site selection, environment preview, and house price preview in the site selection process for commercial areas, industrial areas, and residential areas. In addition, platforms with high rendering capabilities such as Unity can achieve past development, current status, and future design.

[0064] Further, in this embodiment, the urban future plan earth display experience method proposes a third embodiment of the present invention, referring to Figure 7 As shown, in this embodiment, the method for displaying and experiencing the urban future plan on the ground includes:

[0065] Step S1, obtaining point cloud data and image data of a target scene in a target city;

[0066] Step S2, generating a city data set according to the point cloud data, the image data and the city data of the target city;

[0067] Step S3, generating a virtual city model corresponding to the target city according to the city data set, the preset city model and the optimization algorithm;

[0068] Step S4, generating corresponding interaction information according to the terminal parameters of the terminal device and the virtual city model.

[0069] In this embodiment, the city data set is determined by point cloud data and image data, and a virtual city model is generated, so that the RAR technology composed of reality (Reality) and augmented reality (Augmented Reality, AR) can be applied in the government field, so that the government can use RAR technology to intuitively and completely display the planning and design of the new urban area, and improve the transparency and support of the project. At the same time, immersive promotional materials can also be produced in virtual space based on the above technology, and the government can more effectively attract international investment and promote the development of new areas. In addition, since it can be displayed based on the public's smart devices, the RAR technology can be used to increase the activeness of public participation in planning.

[0070] Furthermore, after the step of generating a virtual city model corresponding to the target city according to the city data set, the preset city model and the optimization algorithm, the method further includes:

[0071] The virtual city model is imported into a target platform, and the virtual city model is calibrated according to parameters based on the target platform, wherein the target platform is a Metacity platform.

[0072] In this embodiment, by importing the target platform and calibrating the virtual city model based on the parameters of the target platform, the virtual city model can be effectively standardized, which is conducive to the virtual display and immersive experience of investors in the target platform. The virtual city model includes the display of data such as human flow data, traffic data and environmental data, so that investors can make more accurate investment decisions based on real-time data. And since there is no need to visit the site in person, investors can visit and understand the potential of the project remotely through the RAR device.

[0073] Furthermore, before the step of generating corresponding interaction information according to the terminal parameters of the terminal device and the virtual city model, the step further includes:

[0074] Determine the position parameters of the user during the interaction process according to the visual positioning service and the global positioning system of the terminal device, and use the position parameters as the terminal parameters;

[0075] When the first positioning data of the visual positioning service and the second positioning data of the global positioning system do not match, the first historical output positioning data of the visual positioning service and the second historical output positioning data of the global positioning system are used to determine the position parameter according to a comparison result between the first historical output positioning data and the second historical output positioning data.

[0076] In this embodiment, different types of positioning data may be sorted according to reliability, and the location parameters may be determined according to the sorting result.
