改进平行坐标系框架下的多维电磁态势展现
Visualizing multi-dimensional electromagnetic situation in advanced parallel coordinates
摘要
Abstract
As it's hard to visualize the electromagnetic situation (EMS) with complicated multi-dimensional information by using the traditional approach of modeling the electromagnetic elements in 3D space, then a visualizing framework for multi-dimensional EMS representation was built by advanced parallel coordinates method (APCM). This framework mainly includes four algorithmic modules of a data fitting, a quantitative mapping, an adaptive time-sliding window and a region division. Respectively, the data fitting model mitigates the degree of line overlapping between the correlated adjacent data dimensions by Bezier curve. The quantitative mapping model can map the multi-dimensional information in different sizes and types into the coordinate system. Then the adaptive time-sliding window model can adjust time interval of situation representation dynamically in order to make it adaptable to the change in an electromagnetic environment. In the region division model, an objective function was designed to analyze the trade-off between the computation time cost and the accuracy of region division. The experiments show that the APCM is an effective approach to display multi-dimensional EMS information quickly and precisely. The Bezier fitting between two adjacent data dimension can optimize and highlight the information and relationships of EMS in a well-understood way, which makes it possible to demonstrate the features of distribution and correlation of data in complicated EMS more clearly and more accurately.关键词
