Research on Three-Dimensional Visualization of Substation Based on Aggregation and Dynamic Scheduling
摘要
In order to accelerate the loading speed of three-dimensional visualization scene of substation,this paper proposes a data organization method based on the clustering and aggregation of ground object model and the dynamic scheduling of n-ary tree hybrid index structure.First,the orthographic map of the ground object model is formed and its clustering is achieved.Then,the clustered ground object model is aggregated by the aggregation degree function.Then,the index is built by utilizing the n-ary tree hybrid structure,and so is the three-dimensional display by dynamic scheduling.The three-dimensional test of a UHV power transmission project shows that the clustered aggregated ground object model and the dynamic scheduled n-ary tree hybrid index structure can improve the loading speed of three-dimensional power transmission scene,and effectively support the application of three-dimensional scene visualization in the digital handover of power grid engineering.
