Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of geospatial subdivision, and particularly to a method, device, and equipment for visual hierarchical management of earth subdivision grids based on UE. Background Art

[0002] The earth subdivision grid uses earth subdivision technology to divide the earth's surface and interior, forming multi-level grids with similar shapes, seamless and non-overlapping spaces, and continuous scales. By performing ordered geographic recursive coding on the subdivision grids, grids ranging from the earth scale to the centimeter scale have a unique geographic code. The earth subdivision grid provides a globally common regional reference framework based on grids, which helps the coordination of various action units in joint air-ground operations and the integrated sharing of multi-sector and multi-source geospatial data.

[0003] The visualization of subdivision grids relies on general geometric body modeling methods. Starting from the vertices, each surface is formed in the way of triangular faces, and when combined, a grid body is constructed. To achieve the highest grid generation efficiency, all known grids should be generated and managed in the same object Object, but this will lead to extremely low grid update efficiency. Even if only one grid is changed, all grids need to be deleted and regenerated. To achieve the highest update efficiency, all grids should be generated and managed as separate objects respectively, but this greatly increases the cost of grid generation and rendering, and is prone to causing scene rendering lags. Therefore, a proper way is needed to hierarchically manage the visualized subdivision grids. Summary of the Invention

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

[0061] As Figure 1 shown, an embodiment of the present invention provides a method for visual hierarchical management of earth subdivision grids based on a UE, including:

[0062] S1: Obtain grid data, where the grid data includes earth subdivision grid data, and the earth subdivision grid data is composed of a plurality of sub-grids;

[0063] S2: Perform index coding and type recognition on the sub-grids in the grid data to determine the index information and type information of each sub-grid;

[0064] S3: Divide the sub-grids based on the coding, type information, and area information of each sub-grid;

[0065] S4: Based on the division result, at least create grid segments for the sub-grids of the same type and create grid chunks for the sub-grids of different types;

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

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

[0068] Among them, performing index coding on the sub-grids in the target grid data to determine the index information of each sub-grid includes:

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

[0070] S8: Input the encoded sub - grids into the target engine, so that the target engine decodes the encoded data of the sub - grids, determines the grid corner point information, and obtains the vertex information of the sub - grids by interpolating and coordinate - transforming the corner point information of the grid. The target engine includes a virtualization engine;

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

[0072] Further, the method further includes:

[0073] S10: Input the grid data into the target engine, and the target engine performs visualization processing on the grid data. And

[0074] S11: Perform geographical area division on the sub - grids in the grid data;

[0075] S12: Combine the division result to perform type recognition on the sub - grid data, and determine the type information of each sub - grid.

[0076] Exemplarily, 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, it is necessary to first perform earth subdivision grid encoding on the sub - grids in the grid data. Then, as Figure 2As shown, the grid data is recognized and organized according to grid types and geographical regions. In this embodiment, a single grid corresponds to the concept of SubGrid (sub-grid). When constructing the grid, it is constructed in units of SubGrid. At the same time, SubGrid is also the smallest unit for grid interaction. Specifically, based on the ProceduralMeshComponent (PMC, a component in Unreal Engine that allows users to dynamically generate and modify meshes during engine operation) in the UE, the grid data can be visually processed. At the same time, the encoded information of the sub-grid is decoded to obtain the grid corner point information, and then the vertex information of the sub-grid is obtained through interpolation and coordinate conversion (converting the geodetic coordinates to UE world coordinates). When the vertices of each sub-grid are calculated, a sequence number arrangement of the vertices is naturally obtained. This arrangement corresponds to multiple sub-grids. The UE can obtain the triangular face index of each sub-grid by arranging the vertex sequence numbers, that is, obtain the index information. In this embodiment, sub-grids with the same type but different regions are divided and managed according to grid sections respectively, and grids of different types are divided and managed according to grid chunks respectively. The grid chunk is the smallest unit for distinguishing grid types. It is composed of grid sections, that is, it contains at least one grid section. And as described above, the grid section is composed of sub-grids with the same type but different or the same regions. When sub-grids need to be processed, such as when updating sub-grids, an instruction can be input. At this time, the instruction is input into the UE. The UE can respond to this instruction and only update the grid section containing the specified sub-grid that needs to be updated. Another example is during grid interaction. An instruction can be input. By obtaining the encoded information of the sub-grid being interacted with, that is, the index information, the information query and marking of the sub-grid can be realized.

[0077] Based on the above, it can be seen that in this embodiment, the hierarchical management of the earth's subdivision grid data is realized, including managing different types of subdivision grids, that is, sub-grids, such as terrain grids and route grids, using different grid chunks, and managing each type of grid according to regions using different grid sections. In this way, the hierarchical management of all subdivision grids can be realized, and partial grids can be processed, rather than in the existing solutions where all grids can only be regarded as the same object or each grid is treated as an independent object for processing. Thus, the generation efficiency and update efficiency of the grids can be taken into account when processing the subdivision grids.

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

[0079] S13: At least perform type recognition on the sub-grids in the grid data regarding terrain and routes, and then determine the type information of each sub-grid.

[0080] The method further includes:

[0081] S14: Obtain path information corresponding to the sub-grid, where the path information includes 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, as Figure 3 shown, when performing ground path planning and flight path grid conflict display based on the dissection grid, the system or the user can send path grid data and flight path grid data from the backend to the UE side through the HTTP service to instruct the UE side to perform data processing. In response to the receipt of the data, the UE side organizes the two types of grid data respectively, and at the same time differentiates the data for multiple paths and multiple flight paths through labels.

[0084] After the UE side receives the grid data, it first hands the task to the management module corresponding to different grid segments according to the grid type of the target sub-grid. Commonly used grid segments and grid types include path grids, flight path grids, area coverage grids, etc. Different grid types correspond to different grid chunks, and their visualization forms and attached information are different. The path grid is visualized in a three-dimensional grid form, which includes path start point information, path planning condition information (such as the slope is less than 30 degrees), etc.; the flight path grid is also visualized in a three-dimensional form, which should include time information and flight path conflict information, etc.

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

[0086] The first processing of the target sub-grid by the target grid segment or the second processing with the target grid segment as the operation object based on the processing instruction includes:

[0087] S16: Based on the processing instruction, instruct the management module corresponding to the target network segment to perform first processing on the target grid, and the first processing at least includes 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 second processing with the target grid segment as the operation object, and the second processing includes deletion processing.

[0089] For example, continuing with the previous embodiment, the path grid and the route grid are created as different grid chunks, denoted as PathChunk and RouteChunk respectively. They belong to different class objects and are managed independently without interference. In PathChunk, different paths are created and managed as different sub-grids. Additionally, an index can be set for the grid section. This index, SectionIndex, preferably corresponds one-to-one with the path number. For example, in the case of multi-segment path planning, the UE sends multiple path planning requests to the backend path planning grid service. The path numbers are denoted as ordered natural numbers such as 1 / 2 / 3, etc. After the backend completes the path planning using the grid method, it sends the grid data to the UE in sequence. The UE creates grid sections through CreateMeshSection, and SectionIndex increments after each creation. If a certain path needs to be modified, only the corresponding grid sub-grid needs to be modified. For RouteChunk, the overall implementation principle is the same as that of PathChunk, so it will not be elaborated here.

[0090] In the call of the path planning service based on the UE, the PathPlanningController (path planning controller) manages the generation and deletion of the path grid in the PathGrid class (PathGrid is a component used for path planning in Unity, mainly used to create and manage the path grid). As described above, the deletion is performed on the grid section as the object. When performing multi-segment path planning, the PathPlanningController calls the path planning service multiple times through the HTTPDriver to the backend. Different path segments will correspond to different GridSections of the PathGrid object. If each path segment also contains data such as length and height difference, these data will be recorded in the PathInfoList (path information array) list of PathGrid, which is equivalent to recording the above mapping relationship in the list for information query of sub-grids and grid sections. When the user manually selects a certain path grid in the scene for modification (such as changing the grid color), only the face index FaceIndex information of the selected grid can be obtained at this time. In response to this index, the UE can quickly find the grid section to be modified through the mapping relationship between the grid FaceIndex and SectionIndex saved in the PathInfoList, and display its information for the user to view and indicate for modification. When querying or marking information for a single path grid, such as querying the slope or vegetation information within a specific grid, the grid code or index information of the selected sub-grid is obtained through the ray detection method, and the corresponding information can be queried from the database or the local data table based on this grid code or index information.

[0091] Further, the route sub-grids GridSection corresponding to different routes RouteGrid are different. When each route also includes data such as route time and conflict information with other routes, these data will be recorded in the RouteInfoList list of RouteGrid for information query of the grid segments. When part of the route data is updated, the grid segment can be updated according to 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, call different functional interfaces through the management module to execute the first processing or the second processing.

[0095] Exemplarily, in the UE-based route conflict grid display, the RouteGrid class (corresponding to RouteChunk), derived from the GridInfo class, adds a RouteInfo structure for recording route information, adds a QueryRouteInfo interface and an UpdateRouteInfo interface for querying and modifying route information, is responsible for route grid visualization, and provides extended functional interfaces; the UE can call different interfaces according to different requirements to complete corresponding tasks when performing different tasks.
