| The industrial application department has accumulated a large number of target models and their related electromagnetic characteristics data,and built a database storage.How to effectively visualize a large amount of information in order to assist users to fully explore the correlation and intrinsic information between data,and achieve intuitive understanding and analysis has become an urgent need in the industry.This thesis designs and implements a Web-based target electromagnetic scattering characteristic data visualization tool system.By combining D3.js and WebGL,the system can realize multiple view forms of 2D and 3D on the browser without installing any plug-ins,and through interactive multi-data association and fusion display,users can quickly build complex and diverse an intuitive understanding of the electromagnetic scattering characteristics data.The main work of the thesis is as follows:(1)Based on the detailed requirements analysis,the overall architecture design of the visualization tool system is completed,and the module division of data communication interface,user interaction,two-dimensional data visualization,three-dimensional data visualization and multi-view association visualization is determined.(2)Design and implement the data communication module.Based on the HTTP communication mechanism,the data exchange interface specification between the database and the database is determined,and the data processing and storage are optimized accordingly.(3)Research and implementation of the D3.js-based two-dimensional multi-chart visualization module,especially for page import and interaction optimization,speed up the display of the gradation diagram and its prompt box,by adding an overview + detail interaction to the line graph The user interaction experience of the line graph is improved;the research realizes the 3D visualization module based on the goal and feature of WebGL.(4)A multi-view association visualization scheme based on viewing angle data is designed.The interaction process of view association is analyzed in detail,and the visual analysis of association between 3D view and multiple 2D views is realized.(5)The completed target electromagnetic scattering characteristic data visualization tool system was tested comprehensively,and the availability and effectiveness of the system were verified from the aspects of function and performance.The Web-based target electromagnetic scattering characteristic data visualization tool system designed and implemented in this thesis demonstrates good usability and stability under the normal working of the core module.It has been applied and has good effect. |
