Description

Technical Field

[0001] This invention relates to the field of Earth spatial subdivision technology, and in particular to a method, apparatus and device for visual hierarchical management of Earth subdivision grids based on UE. Background Technology

[0002] The Earth Grid, employing Earth partitioning technology, divides the Earth's surface and interior into multi-layered grids that are approximately identical in shape, spatially seamless and non-overlapping, and scale-continuous. Through ordered recursive geographic coding of these grids, each grid, from those on a global scale to those on a centimeter scale, has a unique geographic code. The Earth Grid provides a grid-based, globally applicable regional reference framework, facilitating coordination among action units in joint air-ground operations and the integration and sharing of multi-sectoral and multi-source geospatial data.

[0003] Mesh visualization relies on general geometric modeling methods, assembling surfaces from vertices into triangular faces to form a mesh. To achieve maximum mesh generation efficiency, all known meshes should be generated and managed within the same object. However, this results in extremely low mesh update efficiency; even changing just one mesh requires deleting and regenerating all others. Alternatively, to achieve maximum update efficiency, each mesh should be generated and managed as a separate object. However, this significantly increases the cost of mesh generation and rendering, potentially causing scene rendering lag. Therefore, a suitable method for hierarchical management of visualized meshes is needed. Summary of the Invention

[0060] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0061] like Figure 1 As shown, this embodiment of the invention provides a method for hierarchical management of Earth mesh visualization based on UE, including:

[0062] S1: Obtain grid data, which includes Earth subdivision grid data, and the Earth subdivision grid data consists of multiple subgrids;

[0063] S2: Index and encode the sub-grids in the grid data, identify their types, and determine the index and type information of each sub-grid;

[0064] S3: Divide the subgrids based on the encoding, type information, and region information of each subgrid;

[0065] S4: Based on the partitioning results, at least create mesh segments for sub-mesh of the same type, and create mesh blocks for sub-mesh of different types;

[0066] S5: In response to the processing instruction of the target sub-grid, determine the corresponding grid block based on the index information, and determine the corresponding target grid segment from the grid block;

[0067] S6: Based on the processing instruction, instruct the target grid segment to perform a first processing on the target subgrid, or perform a second processing on the target grid segment as the operation object.

[0068] Specifically, the sub-grids in the target grid data are indexed and encoded to determine the index information of each sub-grid, including:

[0069] S7: Encode the sub-grids in the grid data;

[0070] S8: Input the encoded sub-mesh into the target engine so that the target engine can decode the encoded data of the sub-mesh, determine the corner information of the mesh, and obtain the vertex information of the sub-mesh by interpolating and transforming the corner information of the mesh. The target engine includes a blurring engine.

[0071] S9: Determine the triangular face index information of each sub-mesh based on the vertex information of each sub-mesh.

[0072] Furthermore, the method also includes:

[0073] S10: The grid data is input into the target engine, which then performs visualization processing on the grid data.

[0074] S11: Divide the subgrids in the grid data into geographical regions;

[0075] S12: Based on the division results, perform type identification on the sub-grid data to determine the type information of each sub-grid.

[0076] For example, the method in this embodiment is implemented based on UE (Unreal Engine). Specifically, the grid data in this embodiment is stored in the form of Earth subdivision grid encoding (hereinafter referred to as grid code), that is, the subgrids in the grid data need to be Earth subdivision grid encoded first. Then, as Figure 2As shown, the grid data is identified and organized according to grid type and geographical region. In this embodiment, a single grid corresponds to the concept of a SubGrid. Grid construction is performed on a SubGrid basis, and the SubGrid is also the smallest unit for grid interaction. Specifically, the grid data can be visualized based on the ProceduralMeshComponent (PMC, a component in Unreal Engine that allows users to dynamically generate and modify grids during engine runtime) in the UE. Simultaneously, the encoded information of the subgrid is decoded to obtain the grid corner information, and then the vertex information of the subgrid is obtained through interpolation and coordinate transformation (converting latitude, longitude, and altitude coordinates to UE world coordinates). After calculating the vertices of each subgrid, a sequence of vertex numbers is naturally obtained. This sequence corresponds to multiple subgrids, and the UE can obtain the triangular face index of each subgrid by arranging the vertex numbers, i.e., obtain the index information. In this embodiment, sub-grids of the same type but different regions are divided and managed according to grid sections. Simultaneously, different types of grids are divided and managed according to grid chunks. A grid chunk is the smallest unit distinguishing grid types, composed of grid sections, meaning it contains at least one grid section. As described above, a grid section consists of sub-grids of the same type but different or the same region. When processing a sub-grid, such as updating it, a command can be input. This command is sent to the UE, and the UE responds by updating only the grid sections containing the specified sub-grids. Furthermore, during grid interaction, a command can be input to obtain the sub-grid code (index information), enabling information querying and marking of the sub-grid.

[0077] Based on the above, this embodiment manages the Earth's grid data hierarchically. This includes managing different types of grids, i.e., sub-grids, such as terrain grids and flight path grids, using different grid blocks. At the same time, each type of grid is managed according to different grid segments for each region. This enables hierarchical management of all grids and allows for processing of some grids, rather than treating all grids as the same object or processing each grid as an independent object as in existing solutions. This achieves the effect of balancing grid generation efficiency and update efficiency when processing grids.

[0078] In one embodiment, type identification is performed on the sub-grids in the grid data to determine the type information of each sub-grid, including:

[0079] S13: At least the subgrids in the grid data are identified in terms of terrain and flight path type, thereby determining the type information of each subgrid.

[0080] The method further includes:

[0081] S14: Obtain the path information corresponding to the sub-grid, the path information including ground path information or flight path information;

[0082] S15: Construct a mapping relationship between the path information and the index information of the corresponding sub-grid, and perform associated storage based on the mapping relationship.

[0083] For example, in practical applications, such as Figure 3 As shown, when performing ground path planning and flight path grid conflict display based on the partitioned grid, the system or user can send path grid data and flight path grid data from the backend to the UE via HTTP service to instruct the UE to process the data. In response to the received data, the UE organizes the two types of grid data separately, and further distinguishes them using labels for cases with multiple paths or multiple flight paths.

[0084] When the UE receives the grid data, it first assigns the task to the management module corresponding to the different grid segments based on the grid type of the target sub-grid. Commonly used grid segments and grid types include path grids, flight path grids, and area coverage grids. Different grid types correspond to different grid chunks, which have different visualization formats and accompanying information. Path grids are visualized in a 3D grid format, containing information such as the path start point and path planning conditions (e.g., a slope of less than 30 degrees). Flight path grids are also visualized in a 3D format, and should include time information and flight path conflict information.

[0085] Furthermore, in this embodiment, each network segment corresponds to a management module;

[0086] The step of instructing the target mesh segment to perform a first process on the target sub-mesh based on the processing instruction, or performing a second process with the target mesh segment as the operation object, includes:

[0087] S16: Based on the processing instruction, instruct the management module corresponding to the target network segment to perform a first process on the target mesh, the first process including at least information query processing, information modification processing, and marking processing; or

[0088] S17: Based on the processing instruction, instruct the management module corresponding to the target network segment to perform a second processing with the target grid segment as the operation object, the second processing including deletion processing.

[0089] For example, continuing from the previous embodiment, the path grid and route grid are created as different grid blocks, denoted as PathChunk and RouteChunk respectively. They belong to different class objects, are managed independently, and do not interfere with each other. In PathChunk, different paths are created and managed as different sub-grids. Additionally, an index can be set for grid segments. This index, SectionIndex, preferably corresponds one-to-one with the path number. For example, taking multi-segment path planning as an example, the UE sends multiple path planning requests to the backend path planning grid service, with path numbers denoted as ordered natural numbers such as 1 / 2 / 3. After the backend completes the path planning using the grid method, it sequentially sends the grid data to the UE. The UE creates grid segments using CreateMeshSection, and the SectionIndex increments after each creation. If a path needs to be modified, only the corresponding sub-grid needs to be modified. The overall implementation principle for RouteChunk is the same as that for PathChunk, so it will not be described further.

[0090] In UE-based path planning service calls, the PathPlanningController manages the generation and deletion of path grids in the PathGrid class (PathGrid is a Unity component used for path planning, primarily for creating and managing path grids). As mentioned earlier, deletion is performed on a grid segment basis. When planning multiple path segments, the PathPlanningController calls the path planning service multiple times to the backend via HTTPDriver. Different path segments correspond to different GridSections of the PathGrid object. If each path segment also contains data such as length and height difference, this data is recorded in the PathInfoList (path information array) of the PathGrid. This is equivalent to recording the above mapping relationship in the list for information retrieval of sub-grids and grid segments. When the user manually selects a path grid segment in the scene for modification (e.g., changing the grid color), only the FaceIndex information of the selected grid is obtained. The UE responds to this index and can quickly find the grid segment to be modified through the mapping relationship between the grid FaceIndex and SectionIndex stored in PathInfoList, displaying its information for the user to view and instruct them to make modifications. When querying or marking information for a single path grid, such as querying slope or vegetation information within a specific grid, the grid code or index information of the selected sub-grid is obtained through ray detection. Based on the grid code or index information, the corresponding information can be queried from the database or local data table.

[0091] Furthermore, different routes correspond to different route sub-grids (GridSection). Each route also includes data such as route time and conflict information with other routes; this data is recorded in the RouteInfoList of the RouteGrid for information retrieval of grid segments. When some route data is updated, the grid segment can be updated based on its original SectionIndex.

[0092] In another embodiment, the method further includes:

[0093] S18: Construct multiple different functional interfaces;

[0094] S19: In response to the processing instruction, the first processing or the second processing is executed by calling different functional interfaces through the management module.

[0095] For example, in the UE-based route conflict grid display, the RouteGrid class (corresponding to RouteChunk) is derived from the GridInfo class. It adds a RouteInfo structure to record route information, and adds QueryRouteInfo and UpdateRouteInfo interfaces to query and modify route information. It is responsible for the visualization of the route grid and provides extended function interfaces. The UE can call different interfaces to complete the corresponding tasks according to different needs and when performing different tasks.
