Research On Key Technologies For Dynamic Simulation And Visualization Of Complex Scenes

As weapon equipment and operational command systems become increasingly information-based,the future battlefield environment will be characterized by greater complexity and diversity.In the process of simulating complex combat situations,a vast amount of data and information is generated,which requires the traditional integrated information platform to urgently enhance its ability to quickly and efficiently acquire the information required by the command staff from these data,and to present it visually for rapid decision-making.To address this issue,this thesis explores the key technology of dynamic simulation data processing and visual display based on complex scene simulation,in order to solve the problems of constructing complex simulation files and single visual effect in traditional battlefield-oriented simulation-visualization platforms.Firstly,based on the established system model,a system behavior description process based on the Compositional Interchange Format(CIF)language is proposed to describe the behavior state of the model.This process enables the rapid and efficient writing of corresponding simulation files based on the system model.For the established simulation files,the CIF toolchain’s simulation solver is used for simulation verification.The comparison of the solution results with ADS-B data yields approximate results,indicating the scientific nature of the methodology described in this thesis.Moreover,we have also studied the key technologies of using Cesium 3D digital earth to visualize dynamic simulation data based on CIF.A method to synchronize time between the simulation module and the visualization module is introduced,which allows the visualization module to preview the simulation data synchronously when it is generated dynamically.We investigate the visualization of complex battlefield environments and various visualization effects in such environments,including information line connection between equipment,explosions,radar scanning,and radar jamming effects.While conventional simulation-visualization display tools could only demonstrate data locally,large-screen integrated display method is proposed with support of multiple devices and cross-platform display based on web-based visualization largescreen display method.Finally,in this thesis,a system model is constructed based on public media resource on the Pelosi’s visit to Taiwan.Based on this model,we further generate the behavior simulation description and construct the visualization scene of the complex scenario,achieve dynamic simulation and visualization module linkage display,which verifies the effectiveness and feasibility of the construction process of system description file and the key technology of visualization processing proposed in this thesis.At the same time,the relevant modules are integrated in the large screen,which solves the problem of single display means of the traditional visualization platform.
