Problems solved by technology

The traditional UE4 engine cannot effectively manage and load drivers for massive GIS data
Under the UE4 engine, there is a lack of a 3D engine specifically for GIS spatial data, resulting in the current technical architecture of "UE4 engine + GIS data". Compatible, GIS spatial analysis does not support issues such as
Therefore, image data that are fully compatible in the same coordinate system will also have problems such as garlands, distortions, and deformations, resulting in incomplete display of large-scale scenes, which can only be demonstrated in blocks, and the 3D visualization effect is not good.
[0005] To sum up, the existing UE4 engine lacks functions such as storage, exchange, and business analysis of GIS data, and does not support a cache loading mechanism for massive multi-source heterogeneous spatial data, resulting in incomplete display of large-scale scenes, which can only be demonstrated in blocks
Secondly, in the existing technical system, some GIS spatial analysis functions are missing, and functions such as path analysis, fill and excavation analysis, and disaster impact buffer analysis cannot be performed, which greatly reduces the capabilities of the 3D system platform

Embodiment 1

[0043] A visualization system based on UE4 engine and Cesium framework, such as Figure 1-Figure 5 As shown, including GIS data acquisition module, Cesium 3D earth model module and UE4 engine, Cesium 3D earth model module is embedded in the UE4 engine shown, GIS data is converted into the support coordinate system of the UE4 engine through the Cesium 3D earth model module, And use the UE4 engine to achieve a brilliant, high-definition 3D graphical interface for geographic coordinate visualization.

[0044] In this embodiment, GIS is an existing conventional geographic information system, which collects, stores, manages, calculates, analyzes, displays and describes relevant geographic distribution data in the entire or part of the earth's surface (including the atmosphere) space. The data is GIS data.

[0045] It should be further explained that the Cesium 3D earth model module includes a field rendering module, a tile map module, a latitude and longitude coordinate conversion...

Embodiment 2

[0092] A novel smart grid visualization method utilizing visualization systems such as figure 2 shown, including the following steps:

[0093] Step S101: Collect power grid-related data through a GIS system, and the collected data at least includes line length, tower type, tower position and horizontal rotation angle;

[0094] Step S102: integrating, classifying and cleaning the collected data, mainly integrating and classifying geographic location data, tower location data and tower model data, and cleaning unnecessary data;

[0095] Step S103: Store the geographic coordinates obtained from the integrated and classified data in the data model library in the data storage module, and import the data into the model library of the UE4 engine to search for the model; if the data model matches, the UE4 engine directly calls the data And directly transform to achieve 3D visualization; if the data model does not match, import the data into the Cesium 3D earth model module;

Abstract

The invention discloses a visualization system and method based on a UE4 engine and a Cesium framework, and relates to the technical field of intelligent power grid information visualization. Comprising a GIS data acquisition module, a Cesium three-dimensional earth model module and a UE4 engine, the Cesium three-dimensional earth model module is embedded into the UE4 engine, GIS data is converted into a support coordinate system of the UE4 engine through the Cesium three-dimensional earth model module, and a gorgeous and high-definition 3D graphical interface with visual geographic coordinates is realized by using the UE4 engine. According to the invention, after data acquisition, all technical links from data management to scene construction to visual expression are broken through, powerful three-dimensional rendering capability and spatial analysis capability are provided, and data processing is faster and more accurate. The three-dimensional visual display of the power grid can be clearer and more comprehensive, and a three-dimensional model with good visual effect and spatial information is constructed.

Description

technical field [0001] The invention relates to the technical field of smart grid information visualization, in particular to a visualization system and method based on a UE4 engine and a Cesium framework. Background technique [0002] Digital twin technology is the most widely used 3D visualization technology in the power grid industry due to its dynamic, realistic, and cool scene characteristics. Summarizing the existing technical solutions, the main work and technical characteristics are as follows: (1) The current mainstream technical system uses UE4 engine + GIS data to construct 3D scenes, GIS data is directly embedded in UE4 engine, and there is no 3D GIS spatial data engine; (2) ) The current traditional technical solution is to use the UE4 game engine as the engine to drive the real scene, and to manually process the collected multi-source GIS spatial data, including image stitching, color leveling, mosaicking, 3D model construction, BIM model construction, terrain ...
