[0023] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0024] The embodiment of the present application provides a three-dimensional real-scene geographic information system, including: a three-dimensional real-scene map display platform 101, a data storage module 102, and an auxiliary analysis module 103, where: The three-dimensional real-scene map display platform 101 is used to perform three-dimensional modeling based on real-scene data and multi-source data to obtain a three-dimensional real-scene map, perform map rendering and interactive processing based on the three-dimensional real-scene map, and present the target three-dimensional real-scene map after the rendering process on the display interface. The three-dimensional real-scene map not only provides geographical location information but also displays detailed information such as the three-dimensional shape, height, and texture of ground objects, so as to obtain a richer spatial perception and provide more intuitive, accurate, and comprehensive support for urban planning and management. The data storage module 102 is used to verify the real-scene data and multi-source data and store the verified real-scene data and multi-source data in a distributed manner. Since the real-scene data and multi-source data involved in the three-dimensional real-scene geographic information system are characterized by diversity and large quantity, the distributed storage method is adopted to achieve the purpose of storing two-dimensional and three-dimensional data on the same platform and achieve the effect of two-dimensional and three-dimensional integrated storage. The auxiliary analysis module 103 is used to perform multi-dimensional auxiliary analysis based on the three-dimensional real-scene map to obtain an auxiliary analysis result, and send the auxiliary analysis result to the planning decision terminal, perform multi-dimensional auxiliary analysis on the three-dimensional real-scene map to meet the user's need for in-depth mining and all-round understanding of geographic information, and help decision-makers make more scientific and accurate decisions.

[0025] A three-dimensional real-scene geographic information system, as Figure 1 shown, the system includes: a three-dimensional real-scene map display platform 101, a data storage module 102, and an auxiliary analysis module 103, where: The three-dimensional real-scene map display platform 101 is used to obtain real-scene data and multi-source data, perform three-dimensional modeling based on the real-scene data and multi-source data to obtain a three-dimensional real-scene map; perform map rendering and interactive processing based on the three-dimensional real-scene map, and present the target three-dimensional real-scene map after the rendering process on the display interface to facilitate the user to perform interactive operations with the target three-dimensional real-scene map; For the embodiment of the present application, the three-dimensional real-scene map display platform 101 is used to obtain real-scene data and multi-source data. The real-scene data is the basic map data of the three-dimensional real-scene map information system, usually referring to the data of the real scene obtained by on-site shooting or scanning. It can accurately reflect the objects, scenes, and their spatial relationships in the real world. Preferably, an unmanned aerial vehicle is used to carry multiple sensors to collect aerial photos from different angles such as vertical and oblique at the same time as the real-scene data; the multi-source data refers to the data collected from multiple different sources. These data can be structured, semi-structured, or unstructured, and have characteristics such as diversity, heterogeneity, dynamicity, complexity, and uncertainty. The multi-source data can be obtained through sources such as social media, sensor networks, public data sets, enterprise databases, and API interfaces.

[0026] Furthermore, three-dimensional modeling is performed based on real-scene data and multi-source data to obtain a three-dimensional real-scene map. The three-dimensional real-scene map not only provides geographical location information but also shows detailed information such as the three-dimensional shape, height, texture, traffic, and economic development of ground features, facilitating a richer spatial perception and providing more intuitive, accurate, and comprehensive support for urban planning and management. There are various specific implementation methods for the three dimensions, which are not limited in the embodiments of this application. In one feasible method, coverage integrity analysis is performed based on the flight pose parameters in the real-scene data. When the flight area of the flight path completely covers the three-dimensional scene area, preprocessing is performed on the multi-dimensional surface images in the real-scene data to obtain target surface images; aerial triangulation is used to calculate the image data of the target surface images to obtain target image data; the multi-view image dense matching technology is used to extract three-dimensional coordinates from the target surface images to obtain a three-dimensional point cloud, and initial modeling is performed based on the three-dimensional point cloud to obtain a three-dimensional white film model; texture mapping is performed based on the target surface images, target image data, and three-dimensional white film model to obtain a textured three-dimensional map, and data filling is performed based on the multi-source data and the textured three-dimensional map to obtain a three-dimensional real-scene map. Of course, other methods can also be used to perform the three-dimensional modeling operation as long as a three-dimensional real-scene map can be obtained.

[0027] After that, a suitable map rendering engine is selected, for example, Mapbox, CesiumJS, etc. This map rendering engine provides rich map rendering functions and APIs, which helps to achieve complex map effects. Then, the three-dimensional real-scene map is imported into the map rendering engine to perform the rendering operation, that is, the attributes such as the style, layer, marker, and color of the map are set through the APIs provided by the rendering engine, and the parameters such as the lighting direction, intensity, and color in the three-dimensional real-scene map are adjusted. At the same time, interactive functions are added to the three-dimensional real-scene map, such as zooming, rotating, panning, clicking, etc., to ensure that users can interact with the three-dimensional real-scene map in real time through the display interface, enhancing the user experience and visual attraction.

[0028] The data storage module 102 is used to perform verification based on the real-scene data and multi-source data, and store the verified real-scene data and multi-source data in a distributed manner; For the embodiments of this application, the three-dimensional real-scene geographic information system involves a large amount of real-scene data and multi-source data. These data are characterized by diversity and large volume, and ordinary relational databases cannot meet their storage needs. To store the real-scene data and multi-source data conveniently and quickly, the distributed storage method is selected in the embodiments of this application. The distributed storage adopts data redundancy and replication technologies and stores the data on multiple physical or logical storage units. Even if a certain storage unit fails, the data will not be lost, ensuring the reliability and persistence of the data. At the same time, the distributed storage method can expand the storage capacity and performance by adding more storage nodes, adapting to the growing demand for the data volume of the three-dimensional real-scene geographic information system without frequently replacing or upgrading storage devices.

[0029] Therefore, based on the real-scene data and multi-source data, data verification is performed. This data verification is used to judge the integrity, accuracy, consistency, legality, and other requirements of the real-scene data and multi-source data, and to check whether the real-scene data and multi-source data comply with the defined verification rules. Furthermore, when the data verification fails, the data that fails the verification is re-obtained or corrected to ensure the accuracy of the data; at the same time, the real-scene data and multi-source data that pass the verification are stored in a distributed manner. The specific implementation process of the distributed storage is as follows: obtain the distributed storage architecture, which consists of a master node and multiple slave nodes; perform data segmentation on the real-scene data and multi-source data that pass the verification to obtain multiple data blocks, and perform distributed storage based on the distributed storage architecture and the multiple data blocks. Among them, the master node stores the metadata information, and each slave node actually stores the content of the data blocks.

[0030] The auxiliary analysis module 103 is used to perform multi-dimensional auxiliary analysis based on the three-dimensional real-scene map to obtain the auxiliary analysis result and send the auxiliary analysis result to the planning decision terminal. Among them, the multi-dimensional auxiliary analysis includes: spatial measurement analysis, inundation analysis, profile analysis, skyline analysis, and sunlight analysis. The auxiliary analysis result is used to support various decision-making activities related to geographic information.

[0031] For the embodiments of the present application, in order to meet the user's needs for in-depth exploration and all-round understanding of geographical information, which helps decision-makers make more scientific and accurate decisions, multi-dimensional assisted analysis is carried out based on a three-dimensional real-scene map to obtain an assisted analysis result. The assisted analysis result helps to quickly identify key issues and potential risks in the geographical space, thereby improving the efficiency and accuracy of the decision-making process. The specific implementation process of the multi-dimensional assisted analysis is as follows: When the multi-dimensional assisted analysis is spatial measurement analysis, measurement calculations are performed based on the coordinate information in the three-dimensional real-scene map to obtain the spatial length and spatial area; when the multi-dimensional assisted analysis is inundation analysis, inundation analysis parameters are obtained, and inundation simulation is carried out based on the inundation analysis parameters and the three-dimensional real-scene map to obtain inundation simulation data; when the multi-dimensional assisted analysis is profile analysis, profile lines are drawn based on the three-dimensional real-scene map to obtain topographic and geomorphic profile lines; when the multi-dimensional assisted analysis is skyline analysis, contour lines are drawn based on the three-dimensional real-scene map to obtain the skyline where the ground objects intersect with the sky; when the multi-dimensional assisted analysis is sunshine analysis, sunshine analysis parameters are obtained, and sunshine simulation is carried out based on the sunshine analysis parameters and the three-dimensional real-scene map to obtain sunshine simulation data; the spatial length, spatial area, inundation simulation data, topographic and geomorphic profile lines, skyline, and sunshine simulation data are integrated to obtain the assisted analysis result.

[0032] It can be seen that in the embodiments of the present application, the three-dimensional real-scene geographic information system includes: a three-dimensional real-scene map display platform 101, a data storage module 102, and an assisted analysis module 103, where: The three-dimensional real-scene map display platform 101 is used to perform three-dimensional modeling based on real-scene data and multi-source data to obtain a three-dimensional real-scene map, and perform map rendering and interactive processing based on the three-dimensional real-scene map. The three-dimensional real-scene map not only provides geographical location information, but also displays detailed information such as the three-dimensional form, height, and texture of ground objects, so as to obtain a richer spatial perception and provide more intuitive, accurate, and comprehensive support for urban planning and management. The data storage module 102 is used to perform verification based on real-scene data and multi-source data, and store the verified real-scene data and multi-source data in a distributed manner. Since the real-scene data and multi-source data involved in the three-dimensional real-scene geographic information system have the characteristics of diversity and large quantity, the distributed storage method is adopted to achieve the purpose of storing two-dimensional and three-dimensional data on the same platform, and achieve the effect of two-dimensional and three-dimensional integrated storage. The assisted analysis module 103 is used to perform multi-dimensional assisted analysis based on the three-dimensional real-scene map to obtain an assisted analysis result, and send the assisted analysis result to the planning decision terminal, and perform multi-dimensional assisted analysis on the three-dimensional real-scene map to meet the user's needs for in-depth exploration and all-round understanding of geographical information, which helps decision-makers make more scientific and accurate decisions.

[0033] Further, in order to achieve precise positioning, rapid query, and efficient query of natural resources, and improve the accuracy and efficiency of natural resource management, the embodiments of the present application further include: A natural resource management module, configured to, when detecting a resource query instruction, perform instruction parsing based on the resource query instruction to determine resource query information, and perform data query based on the resource query information and a three-dimensional real-scene map to determine a natural resource data set; Perform local area screening based on the resource query information and the three-dimensional real-scene map to determine a two-dimensional area map and a three-dimensional area map, and associate the two-dimensional area map and the three-dimensional area map to achieve two-dimensional and three-dimensional map linkage.

[0034] For the embodiments of the present application, with the development of social economy, natural resource management has become increasingly complex and refined. The traditional two-dimensional maps and manual management methods are difficult to meet the needs of modern natural resource management. Therefore, in the embodiments of the present application, a natural resource management module is set up to perform data query using a three-dimensional real-scene map, and the two-dimensional and three-dimensional map linkage method is adopted to intuitively display the spatial form and three-dimensional structure of natural resources, so as to achieve precise positioning, rapid query, and efficient query of natural resources, greatly improving the accuracy and efficiency of natural resource management.

[0035] Specifically, the user can input resource query requirements through the display interface, and the three-dimensional real-scene geographic information system automatically converts the resource query requirements into resource query instructions. At the same time, the natural resource management module continuously monitors the resource query instructions within the system. When detecting a resource query instruction, it performs instruction parsing based on the resource query instruction to determine resource query information. The instruction parsing process includes, but is not limited to: identifying the instruction type, parameters, and format, and extracting the natural resource information that the user hopes to query. The resource query information includes, but is not limited to: resource type (such as water resources, mineral resources, land resources, etc.), geographical location (such as longitude and latitude range, administrative division, etc.), time range (such as historical data, real-time data, etc.). Furthermore, according to the resource query information, search for a natural resource data set that meets the query conditions in the three-dimensional real-scene map, and return the natural resource data set to the display interface, so that the user can intuitively and precisely query the required resource data. The natural resource data set includes multiple related data points, data lines, and data surfaces, jointly constituting the natural resource information required by the user.

[0036] Furthermore, in order to more accurately and intuitively display the natural resource information required by the user, the natural resource management module will perform local area screening on the three-dimensional real-scene map according to the resource query information to determine the two-dimensional area map and the three-dimensional area map. Among them, the two-dimensional area map is a planar view including the query area, and the three-dimensional area map is a three-dimensional perspective to display the three-dimensional structure and spatial distribution of the user's query area. Then, the two-dimensional area map and the three-dimensional area map are associated to achieve the linkage of the two-dimensional and three-dimensional maps, that is, the connection between the two-dimensional area map and the three-dimensional area map is established through a specific identifier to ensure that each point or area on the two-dimensional map can find the corresponding three-dimensional representation in the three-dimensional map. There are various specific operations for the linked display, which are not limited in the embodiments of the present application. For example, the user can switch and interact between the two-dimensional area map and the three-dimensional area map through the user interface, that is, when the user clicks on a certain point on the two-dimensional area map, the system can automatically switch to the three-dimensional area map and display the three-dimensional structure and surrounding environment of the point in three-dimensional space; similarly, when the user performs operations such as zooming, rotating, or panning in the three-dimensional area map, the two-dimensional area map will also be updated accordingly to reflect these changes.

[0037] It can be seen that in the embodiments of the present application, the natural resource management module is used to, when detecting a resource query instruction, perform instruction parsing based on the resource query instruction to determine the resource query information, and perform data query based on the resource query information and the three-dimensional real-scene map to determine the natural resource data set. Then, based on the resource query information and the three-dimensional real-scene map, local area screening is performed to determine the two-dimensional area map and the three-dimensional area map, and the two-dimensional area map and the three-dimensional area map are associated to achieve precise positioning, fast query, and efficient query of natural resources, greatly improving the accuracy and efficiency of natural resource management.

[0038] Furthermore, in order to enhance the realism and detail richness of the three-dimensional model and enrich the information content of the three-dimensional real-scene map, in the embodiments of the present application, when the three-dimensional real-scene map display platform 101 performs three-dimensional modeling based on real-scene data and multi-source data to obtain the three-dimensional real-scene map, it is used for: Perform coverage integrity analysis based on the flight pose parameters in the real-scene data. When the flight area of the flight line completely covers the three-dimensional scene area, perform preprocessing on the multi-dimensional surface images in the real-scene data to obtain the target surface images; Use aerial triangulation to calculate the image data of the target surface images to obtain the target image data; Use the multi-view image dense matching technology to extract the three-dimensional coordinates of the target surface images to obtain the three-dimensional point cloud, and perform initial modeling based on the three-dimensional point cloud to obtain the three-dimensional white film model; Perform texture mapping based on the target surface image, target image data, and 3D white film model to obtain a textured 3D map, and perform data filling based on multi-source data and the textured 3D map to obtain a 3D real-scene map.

[0039] For the embodiments of this application, the flight pose parameters record information such as the position and attitude of the aircraft when collecting real-scene data. By performing coverage integrity analysis on the flight pose parameters, it can be confirmed whether the aircraft has covered all important parts of the 3D scene area during the shooting process, without missing or overlapping shooting areas. This step is the basis for constructing a complete and accurate 3D real-scene map, so as to improve the accuracy and integrity of the 3D real-scene map. When the route flight area does not completely cover the 3D scene area, control the aircraft to the unshot area for supplementary image collection; when the route flight area completely covers the 3D scene area, perform preprocessing on the multi-dimensional surface images in the real-scene data to obtain the target surface image. Among them, the preprocessing includes but is not limited to: equalization of illumination and color, geometric correction, geodetic correction, radiometric calibration, image enhancement, etc.

[0040] Furthermore, use aerial triangulation to calculate the image data of the target surface image to obtain the target image data. The image data calculation in this step is used to determine the position, attitude, and attributes of the target surface image during shooting, so as to establish the correspondence between the image and the ground. The specific implementation process of the image data calculation is as follows: Extract the image data based on the target surface image to determine the target image data, and judge whether there is abnormal image data in the target image data. When there is abnormal image data, perform aerial triangulation based on the abnormal surface image corresponding to the abnormal image data to determine the qualified image data, and use the qualified image data to update the target image data. Among them, the target image data includes: relative orientation and absolute orientation.

[0041] Meanwhile, using the multi-view image dense matching technology, the three-dimensional coordinates of the target surface image are extracted to obtain a three-dimensional point cloud. Among them, the multi-view image dense matching technology is a technology that extracts the three-dimensional coordinates of corresponding points in the image by comparing and analyzing multiple images taken from different perspectives. The operation process of the multi-view image dense matching technology is as follows: In each image of the target surface image, stable feature points are extracted using a feature point detection algorithm, and the descriptors of these feature points are calculated. The descriptor is a vector used to describe the image information around the feature point, which can help the algorithm identify corresponding feature points in different images; then, using the similarity measure between the feature point descriptors, corresponding feature points are found between different images; furthermore, after obtaining accurate feature point matching pairs, the three-dimensional coordinates of these feature points can be calculated using the triangulation principle, and a three-dimensional point cloud with higher resolution and higher accuracy can be generated using the multi-view stereo matching algorithm. Furthermore, based on the three-dimensional point cloud, an initial model is built to obtain a three-dimensional white film model. The three-dimensional white film model is a simplified three-dimensional model that only contains the geometric shape information of the model and does not contain surface attributes such as texture and color, usually presented as white or gray.

[0042] After that, based on the relative orientation and absolute orientation given in the target image data, the target surface image is mapped into the three-dimensional white film model to obtain a textured three-dimensional map. Among them, performing texture mapping can make full use of the target surface image, enhancing the realism and detail richness of the three-dimensional model. Finally, based on the multi-source data and the textured three-dimensional map, data filling is performed to obtain a three-dimensional real-scene map. The specific implementation process for data filling is as follows: The multi-source data is spatially matched and aligned to ensure the spatial consistency of the data, and the corresponding position information of the multi-source data is fused into the textured three-dimensional map to form a three-dimensional real-scene map with rich information. Performing data filling helps to make full use of the advantages of various data sources, enrich the information content of the three-dimensional real-scene map, not only improving the practicality and application value of the map, but also providing users with more diverse query and interaction methods.

[0043] It can be seen that in the embodiments of the present application, coverage integrity analysis is performed based on the flight pose parameters in the real scene data. This step is the basis for constructing a complete and accurate three-dimensional real scene map, so as to improve the accuracy and integrity of the three-dimensional real scene map. Furthermore, when the flight route area completely covers the three-dimensional scene area, preprocessing is performed based on the multi-dimensional surface images in the real scene data to obtain the target surface images. Then, aerial triangulation is used to calculate the image data of the target surface images to obtain the target image data, and the multi-view image dense matching technology is used to extract the three-dimensional coordinates of the target surface images to obtain the three-dimensional point cloud. After that, initial modeling is performed based on the three-dimensional point cloud to obtain a three-dimensional white film model, and texture mapping is performed based on the target surface images, target image data, and three-dimensional white film model to obtain a textured three-dimensional map. Performing texture mapping can make full use of the target surface images, enhancing the realism and detail richness of the three-dimensional model. Finally, data filling is performed based on the multi-source data and the textured three-dimensional map to obtain a three-dimensional real scene map. Performing data filling helps to make full use of the advantages of various data sources, enrich the information content of the three-dimensional real scene map, not only improving the practicality and application value of the map, but also providing users with more diverse query and interaction methods.

[0044] Further, to ensure the accuracy of the target image data, in the embodiments of the present application, when the three-dimensional real scene map display platform 101 performs the calculation of the image data of the target surface images by using aerial triangulation to obtain the target image data, it is used for: Extracting image data based on the target surface images to determine the target image data, and judging whether there is abnormal image data in the target image data. When there is abnormal image data, aerial triangulation is performed based on the abnormal surface images corresponding to the abnormal image data to determine the qualified image data, and the target image data is updated by using the qualified image data.

[0045] For the embodiments of the present application, extracting image data based on the target surface images to determine the target image data, the image data calculation in this step is used to determine the position, pose, and attributes of the target surface images when they are taken, so as to establish the corresponding relationship between the images and the ground. Furthermore, it is judged whether the extracted target image data is accurate, and the inaccurate target image data is recorded as abnormal image data. For the abnormal image data, the aerial triangulation technical means is used to calculate the abnormal surface images to determine the accurate qualified image data. Finally, the target image data is updated by using the qualified image data to ensure the accuracy of the target image data, laying a foundation for the subsequent creation of the three-dimensional model.

[0046] For aerial triangulation, this measurement method mainly utilizes the geometric relationships between target surface images, and determines the positions, poses, and attributes of the target surface images during shooting through mathematical methods, thereby establishing the corresponding relationship between the images and the ground. Specifically, feature points are automatically detected and extracted from abnormal surface images. These feature points are usually points that are easy to identify and match in the images, such as corner points, edge points, etc. Then, a matching algorithm is used to match these feature points between different images to establish the corresponding relationship between the images. Furthermore, relative orientation is performed, that is, using the matched feature points, the relative position relationship between the images is calculated through mathematical methods, namely the rotation and translation parameters between the images; absolute positioning is performed, that is, the geometric relationship between the images obtained from relative orientation is combined with ground control points, and the absolute position relationship of the images is calculated through mathematical methods, namely the absolute position and pose of the images during shooting.

[0047] It can be seen that in the embodiment of the present application, image data extraction is performed based on the target surface images to determine the target image data. Then, it is judged whether there is abnormal image data in the target image data. When there is abnormal image data, aerial triangulation is performed based on the abnormal surface images corresponding to the abnormal image data to determine the qualified image data, and the target image data is updated using the qualified image data. Updating the target image data with the qualified image data ensures the accuracy of the target image data and lays a foundation for creating a three-dimensional model in the subsequent steps.

[0048] Furthermore, in order to meet the user's needs for in-depth mining and all-round understanding of geographic information, and to help decision-makers make more scientific and accurate decisions, in the embodiment of the present application, when the auxiliary analysis module 103 performs multi-dimensional auxiliary analysis based on the three-dimensional real scene map and obtains the auxiliary analysis result, it is used for: When the multi-dimensional auxiliary analysis is spatial measurement analysis, measurement calculations are performed based on the coordinate information in the three-dimensional real scene map to obtain the spatial length and spatial area; When the multi-dimensional auxiliary analysis is inundation analysis, inundation analysis parameters are obtained, and inundation simulation is performed based on the inundation analysis parameters and the three-dimensional real scene map to obtain inundation simulation data; When the multi-dimensional auxiliary analysis is profile analysis, profile lines are drawn based on the three-dimensional real scene map to obtain topographic and geomorphic profile lines; When the multi-dimensional auxiliary analysis is skyline analysis, contour lines are drawn based on the three-dimensional real scene map to obtain the skyline where the ground objects intersect with the sky; When the multi-dimensional auxiliary analysis is sunshine analysis, sunshine analysis parameters are obtained, and sunshine simulation is performed based on the sunshine analysis parameters and the three-dimensional real scene map to obtain sunshine simulation data; Based on the comprehensive spatial length, spatial area, inundation simulation data, topographic and geomorphic profile lines, skyline, and sunshine simulation data, the auxiliary analysis result is obtained.

[0049] For the embodiments of the present application, in order to meet the user's needs for in-depth exploration and all-round understanding of geographical information, which helps decision-makers make more scientific and accurate decisions, multi-dimensional assisted analysis is performed based on a three-dimensional real-scene map to obtain an assisted analysis result. The dimensions of the multi-dimensional assisted analysis include, but are not limited to: spatial measurement analysis, inundation analysis, profile analysis, skyline analysis, and sunshine analysis. The assisted analysis result helps to quickly identify key issues and potential risks in the geographical space, thereby improving the efficiency and accuracy of the decision-making process.

[0050] Specifically, when the multi-dimensional assisted analysis is spatial measurement analysis, measurement calculations are performed based on the coordinate information in the three-dimensional real-scene map to obtain the spatial length and spatial area. The specific process of the measurement calculation is as follows: First, clarify the spatial object to be measured in the three-dimensional real-scene map, such as a line segment, polygon, etc.; then, according to the spatial object to be measured, extract its corresponding coordinate information, that is, for a line segment, the coordinates of the starting point and the ending point need to be extracted; for a polygon, the coordinates of all vertices need to be extracted; furthermore, according to the spatial measurement calculation method, calculate the spatial length or spatial area corresponding to each spatial object in the three-dimensional real-scene map.

[0051] When the multi-dimensional assisted analysis is inundation analysis, inundation analysis parameters are obtained, and inundation simulation is performed based on the inundation analysis parameters and the three-dimensional real-scene map to obtain inundation simulation data. The specific process of the inundation simulation is as follows: Obtain inundation analysis parameters, which include, but are not limited to: flood water level, inundation speed, inundation duration, rainfall intensity, terrain roughness, distribution of buildings and obstacles, etc.; then, input the inundation analysis parameters into the three-dimensional real-scene map for inundation simulation to obtain inundation simulation data, that is, the three-dimensional real-scene map will simulate the flood inundation process according to the inundation analysis parameters, and present the inundation result in a graphical manner, for example, an inundation range map, an inundation depth map, etc. This inundation simulation data helps to intuitively understand the situation and severity of the flood inundation.

[0052] When the multi-dimensional assisted analysis is profile analysis, a profile line is drawn based on the three-dimensional real-scene map to obtain a topographic and geomorphic profile line. The line where the profile intersects the terrain surface is called the profile line. Using a line to replace a surface, and then studying the changes in the ground features and landforms in the area where the profile line is located can truly reflect the surface terrain situation intuitively. Applying profile analysis can provide a reference basis for land planning and utilization, construction project site selection, design plan decision-making, etc.

[0053] When the multi-dimensional auxiliary analysis is skyline analysis, the contour line is drawn based on the three-dimensional real-scene map to obtain the skyline where the ground objects intersect with the sky. The skyline refers to the contour line where the ground objects intersect with the sky and is a concentrated representation of the image and style. Therefore, the depth buffer algorithm is used to draw the skyline. First, the depth of the scene within the field of view is initialized to zero. At this time, the depth value of the sky box is zero. Then, the depth values of other objects in the scene except the sky are written into the depth buffer, and the depth values are non-zero. The non-zero depths are traversed and detected to find the non-zero depths adjacent to the depth of zero. Finally, these non-zero depths are written into the color buffer to draw the skyline, that is, the contour line where the ground objects intersect with the sky.

[0054] When the multi-dimensional auxiliary analysis is sunlight analysis, sunlight analysis parameters are obtained, and sunlight simulation is performed based on the sunlight analysis parameters and the three-dimensional real-scene map to obtain sunlight simulation data. The specific implementation process for sunlight simulation is as follows: Obtain sunlight analysis parameters, which include but are not limited to: sunlight analysis start time, end time, sampling frequency, sun position, atmospheric conditions, etc.; then, input the sunlight analysis parameters into the three-dimensional real-scene map for sunlight simulation to obtain sunlight simulation data, that is, calculate the sunlight time and intensity of each point in the analysis area, which can help designers and planners evaluate the daylighting effect of buildings and optimize the design scheme.

[0055] It can be seen that in the embodiments of the present application, in order to meet the user's needs for in-depth mining and comprehensive understanding of geographic information, help decision-makers make more scientific and accurate decisions, multi-dimensional auxiliary analysis is performed based on the three-dimensional real-scene map to obtain auxiliary analysis results. The dimensions of the multi-dimensional auxiliary analysis include but are not limited to: spatial measurement analysis, inundation analysis, profile analysis, skyline analysis, and sunlight analysis. The auxiliary analysis results help quickly identify key issues and potential risks in the geographic space, thereby improving the efficiency and accuracy of the decision-making process.

[0056] Furthermore, in order to uniformly store the real-scene data and multi-source data, ensure the reliability and persistence of the data, and adapt to the growing demand for data volume, in the embodiments of the present application, when the data storage module 102 performs distributed storage of the verified real-scene data and multi-source data, it is used for: Obtain a distributed storage architecture, which consists of a master node and multiple slave nodes; Perform data segmentation based on the verified real-scene data and multi-source data to obtain multiple data blocks, and perform distributed storage based on the distributed storage architecture and the multiple data blocks. Among them, the master node stores metadata information, and each slave node actually stores the content of the data blocks.

[0057] For the embodiments of this application, the three-dimensional real-scene geographic information system involves a large amount of real-scene data and multi-source data. These data are characterized by diversity and large volume, and ordinary relational databases cannot meet their storage needs. To store the real-scene data and multi-source data conveniently and quickly, the distributed storage method is selected in the embodiments of this application. The distributed storage adopts data redundancy and replication technologies, and stores the data on multiple physical or logical storage units. Even if a certain storage unit fails, the data will not be lost, ensuring the reliability and persistence of the data. At the same time, the distributed storage method can expand the storage capacity and performance by adding more storage nodes, adapting to the growing demand for the data volume of the three-dimensional real-scene geographic information system, and there is no need to frequently replace or upgrade the storage device.

[0058] Specifically, the three-dimensional real-scene geographic information system pre-stores a distributed storage architecture, which is a distributed storage architecture designed by technicians according to the architecture design principle, data organization structure, and load balancing principle. This distributed storage architecture is a high-performance, highly reliable, and scalable distributed storage system. The distributed storage architecture consists of a master node and multiple slave nodes. Among them, the master node is the core of the entire distributed storage system and is responsible for coordinating and controlling the work of the slave nodes in the system, that is, mainly responsible for managing information such as the file structure, namespace, and storage location of the data in the file system. Since the master node needs to interact with the slave nodes frequently, it needs to have high processing capabilities and memory resources to ensure the response speed and stability of data storage. The slave nodes are responsible for storing the actual data and performing data read and write operations according to the instructions of the master node. The number of slave nodes can be dynamically expanded according to the needs of the distributed storage system to improve the storage capacity and performance.

[0059] Furthermore, a data segmentation strategy is obtained. This data segmentation strategy is formulated based on the characteristics of the data in the geographic information system and business requirements, and users can set it by themselves according to the actual situation. Regarding this, the embodiments of this application will not make further limitations. Then, according to the preset data segmentation strategy, the verified real-scene data and multi-source data are segmented to obtain multiple data blocks, which serve as the basic units of distributed storage. Preferably, during the data segmentation process, the data is segmented according to a data block size of 128 M, and small file merging is automatically completed for small file data. After that, distributed storage is performed based on the distributed storage architecture and multiple data blocks, that is, the master node stores the metadata information, and each slave node actually stores the content of the data block. The metadata information includes, but is not limited to: data block ID, size, and storage location. To improve the reliability and fault tolerance of the data, the distributed storage system usually adopts data synchronization and backup technologies to store copies of the data blocks on multiple slave nodes to ensure that the data can be recovered from other slave nodes in case a certain slave node fails.

[0060] It can be seen that in the embodiments of the present application, in order to conveniently and quickly store real-scene data and multi-source data in a unified manner, a distributed storage architecture is obtained. Based on the verified real-scene data and multi-source data, data segmentation is performed to obtain multiple data blocks, and distributed storage is performed based on the distributed storage architecture and the multiple data blocks. The distributed storage adopts data redundancy and replication technologies, and stores the data on multiple physical or logical storage units. Even if a certain storage unit fails, the data will not be lost, ensuring the reliability and persistence of the data. At the same time, the distributed storage method can expand the storage capacity and performance by adding more storage nodes, adapting to the growing demand for the data volume of the three-dimensional real-scene geographic information system, and eliminating the need to frequently replace or upgrade storage devices.
