Description

Technical Field

[0001] The present application relates to the technical field of power transmission and distribution lines, and in particular to a method, apparatus, system, equipment and medium for processing a three-dimensional parametric model of a power transmission and distribution line. Background Art

[0002] The parametric modeling of the distribution network lines with a total length of hundreds of thousands of kilometers has realized the same-screen presentation of the distribution network lines in the three-dimensional scene. Among them, the data volume involved in the distribution line tower model and the distribution equipment model is even larger. The current implementation method is to load the distribution network line three-dimensional model (including distribution line towers, box-type substations and other distribution equipment) starting from the 18th level of the three-dimensional map. Due to the large number of equipment, there are certain performance issues in loading the distribution network line grid three-dimensional model on the three-dimensional map. For example: the current distribution network tower basic component model is conventionally about 10M in size, while the number of distribution network line towers in the entire region is huge. The total volume of all distribution network line tower models can usually reach more than 4G. If the distribution network line three-dimensional model needs to be presented on the user-side computer, the user-side computer graphics card GPU configuration has high requirements. The existing conventional computer configuration is usually an integrated graphics card. Loading the distribution network grid has problems such as long front-end page loading time.

[0003] Currently, the matching between the 3D tower model and the tower record is manually confirmed by the front end based on the line. All tower models need to be confirmed one by one, and the connection relationship between the towers is manually drawn. This has at least the following shortcomings:

[0004] 1. Due to the huge amount of data in the three-dimensional tower model, it takes a long time to load the front-end page. At the same time, the number of requests to the back-end tower model data interface is huge, and the system load is high.

[0005] 2. The matching of the 3D tower model with the tower inventory and the marking of lines between adjacent towers based on the line as a unit all require manual confirmation and matching. Due to the large number of towers, manual confirmation requires a lot of manpower and is prone to confirmation errors. In addition, the subsequent 3D modeling of power transmission and substation will display 3D models of multiple disciplines in the 3D scene, and the performance bottleneck will become more prominent. The current manual confirmation method is not scalable and may not be able to meet the needs of 3D model overlay on the subsequent 3D maps of power transmission and substation.

[0046] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0047] It should be noted that although the device schematics illustrate functional module divisions and the flowcharts illustrate logical sequences, in certain circumstances, the steps shown or described may be performed in a sequence that differs from the module divisions in the device or the sequence in the flowcharts. The terms "first," "second," and so on, in the specification, claims, and drawings, are used to distinguish similar items and are not necessarily used to describe a specific sequence or precedence.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0049] The following combination Figure 1 , taking a specific application example to illustrate the processing method of the three-dimensional parameterized model of the transmission and distribution line in the embodiment of the present application.

[0050] Based on the current status of 3D model processing, it is considered to develop a 3D model slicing tool in the intranet environment, and automatically process the overall model generated after the 3D model is accurately associated and matched in the operation records of the distribution lines and transmission lines in the parametric modeling public service center project online. The overall model of the distribution and transmission lines is processed by LOD slicing to complete the matching relationship in advance, and then the overall slicing is performed to reduce the model volume. This can greatly reduce the number of interface accesses that the client requests the server to obtain the tower and equipment models, improve the access speed of the client request model, and thus improve the overall rendering efficiency of the 3D scene model.

[0051] 1. Reduce the number of times the front-end (i.e. client) accesses the back-end (i.e. server) interface based on the line

[0052] Traditional rendering of distribution network tower data requires dynamic online matching of tower records and tower models on the front-end interface. When too many tower models need to be loaded, verification logic needs to be written to control whether models in different areas are displayed or hidden. Using a 3D model slicing tool can automatically release video memory when the overall distribution line model is loaded.

[0053] 2. LOD level loading improves efficiency

[0054] Adopting an on-demand "lazy loading" strategy, LOD hierarchical loading allows users to load 3D model resources only when needed (e.g., zooming in to level 18 in a 3D scene to display the model), thereby improving application performance, responsiveness, and loading performance. LOD (Level of Detail) is a technology used to dynamically select models of different detail levels based on the distance between the object and the camera. When the object is close to the camera, a high-detail model is used; when the object is far away, a low-detail model is used. This method can significantly reduce the rendering burden and improve rendering efficiency.

[0055] The specific steps of processing using the 3D model slicing tool in this embodiment are as follows:

[0056] (1) Select the line with the bound parametric model: Access the three-dimensional parametric model of the line that has been successfully bound in the operational model library module of the parametric modeling public service center project, filter the line list in the platform that has completed the associated binding of the line ledger and the line three-dimensional model, select a line for slicing, and read the basic information of the line ledger and tower ledger associated with the line model, such as the line tower list, tower shape, location coordinates, conductor connection relationship, etc.

[0057] (2) Obtain the tower model file associated with the line tower: Based on the line ledger and the tower ledger data information corresponding to the line in the power grid resource business, the tower ledger and the model are associated and queried through the association relationship in the database to obtain the tower model files associated with all the tower ledgers under the line.

[0058] (3) Tower model file format verification: Automatically judge and verify the tower model file format, allowing Obj, glb, and gltf formats, and uniformly process all tower basic component model file formats into GLB format.

[0059] (4) Model ledger association analysis: Each line ledger contains line ledger attributes and a list of tower ledger attributes under the line. Line ledger attributes include line name, operation number, voltage level, affiliated city, maintenance team, start / end substation and other attribute information. Line-related tower attribute data includes tower GIS information (tower spatial location coordinate information: longitude, latitude, height), physical attributes (such as tower model, tower height, etc.), operation attributes (tower nature, affiliated line, tower name, adjacent tower conductor connection information, etc.) and model entity file application information. This part of the data has been structured and stored in the database. This tool can use the backend query service to analyze the line ledger, tower ledger, tower GIS attributes, physical attributes, operation state attributes and entity model file information of the tower to achieve ledger and model data.

[0060] (5) Slicing of a single tower model: The tool slices each tower data according to the tower shape data of different towers, and manually binds the tower name, tower type, model, coordinates and other important information in the tower ledger to the 3D model of each tower. Then, by parsing the GIS attribute values ​​of the line-related tower (longitude, latitude, height), the spatial reference information SRS (Spatial Reference System) required for the line data resource to perform the slicing operation is calculated and generated. It is a mathematical framework for describing the location of geographic features on the earth's surface. Its main function is to map a set of coordinates to the corresponding real location on the earth. Here, only the spatial information parameters that the model file must have before performing the slicing operation are calculated, which is the location information data required to generate the 3dTiles slice file. The entity model file information of the line-associated tower obtained through analysis is used to identify the tower model category. For non-GLB models, the OBJ model SDK library is used to convert the OBJ model into a GLB model. After each tower model and the actual spatial position information of the tower ledger (including longitude, latitude, elevation and other position attributes) are parsed, a 3dtiles file of a local slice of the 3dtiles line tower is generated.

[0061] (6) Overlay of hanging lines on adjacent tower models: By parsing and reading the connection relationship between adjacent conductors in the tower ledger (the start tower code and the end tower code contained in the conductor segment ledger), and reading the tower GLB model corresponding to each tower ledger (each tower model has a hanging line point set at the corresponding position), the platform generates a Geojson file based on the hanging line point and simultaneously generates a 3dtiles file. The front-end code reads the Geojson file to load and present the hanging line vector data between adjacent towers on the three-dimensional map, and at the same time overlays the hanging line relationship on the 3dtiles file of the generated 3dtiles line tower local slice. Specifically, the client obtains the coordinates of the conductor hanging line points of the adjacent target tower model by parsing the Geojson file, and calculates the spatial vector relationship between the hanging line points based on this, and finally dynamically generates and presents the geometric body of the conductor connection between the towers on the three-dimensional map.

[0062] (7) Compression and merging of overall model slices: Based on the local slice files of multiple towers under the line, spatial grid aggregation is performed on the high-precision model based on vertex clustering to initially reduce redundant vertices; then an incremental simplification algorithm is used to dynamically optimize the simplification process: the algorithm calculates the quadratic error matrix for each triangle vertex, and generates a low-poly (low-precision) tower model that meets the loading requirements of different LOD levels by iteratively merging the vertex pairs with the smallest error increment. The low-poly model is further merged with the model material and vertex compression, and then output as an overall slice data set with LOD level, thereby completing the compression and merging of all the tower 3dtiles local slice files under the overall line to generate the overall line 3dtile slices. LOD technology can effectively reduce the number of vertices that need to be processed, improve rendering efficiency, and support loading the overall slice file on the application side.

[0063] By implementing the above embodiment, there are at least the following effects:

[0064] 1. Improved the rendering efficiency of large-scale 3D models: The technology of slicing tower models and overall line models has greatly reduced the number of requests from the original front-end page to the back-end tower model data interface (the base amount of tower basic data managed under the line is large). At the same time, LOD loading is used to avoid unnecessary resource consumption, and the optimized parameters of 3dtiles can be used for loading.

[0065] 2. Reduce manpower input: The line 3D model slicing tool developed by the parametric modeling public service center project realizes the automatic association setting of the basic ledger attributes of the tower 3D model. It uses the line as the basic unit and implements automated processing processes such as slicing the line tower basic component model, generating hanging wires between towers, and slicing the overall line model. It supports automatic processing of the 3D models of distribution lines and transmission lines that have been bound to the operation ledger according to the line dimension, reducing the manpower input of manual model processing.
