Research On Visualization Technology Of Three-dimensional Battlefield Situation Data

Modern warfare is already a systematic war.The battlefield goal is no longer an isolated individual,but an organic whole.There are complex and diverse relationships such as combat formation,communication network,command and control,surveillance and reconnaissance.In the military geographic information system,these network topological relationships are displayed in the 3D battlefield,that is,the problem of visualizing the 3D battlefield target relationship.How to clearly and intuitively present the relationship between these objectives in front of the combat commanders is a key step in assisting decision-making..In today's military geographic information system,the representation of target monomers is basically mature,but the expression of the relationship between goals is still missing.At the same time,in the battlefield environment,the connection of topological relations is affected by the battlefield environment,mainly affected by the terrain.The visualization under the terrain data is the basis of the battlefield visualization,and the current network topology visualization does not consider the terrain constraints.When the basic display problems are solved,there are also problems in how to better display key information in 3D large amounts of data for people to understand.In view of the characteristics of 3D battlefield visualization,this paper starts with the 3D battlefield target relationship connection line drawing,the multiple diverse relationship representation,and the visual display of various information,and analyzes the battlefield target relationship visualization and gives The basic solution to the three problems.Then the visual display of the 3D target relationship connection line is realized,and a convex hull-based 3D drawing method is proposed,which lays a foundation for the visualization of the entire battlefield network.Finally,the information of the target relationship is visually displayed,and the 3D flying line display effect is realized.The information classification design and implementation are also carried out,and the method of using the hierarchical display of important information is used to enhance the display capability of the relationship information,and the 3D battlefield is The research and development of the visualization of complex data is of great significance.
