Design Of A Regional Virtual Battlefield Environment Support System

Map is a kind of important tool based on some certain mathematical laws.It is used of displaying,recording,calculate and analysis the relationship among things of geographic spatial location.With the development of science of computer and mapping technology,and the battlefield environment of modern war has become more and more complicated,the traditional paper-based maps are unable to meet the needs of modern wars based on highly informationization,it has gradually shown its limitations in various aspects in the real wars.Because of its good characteristics like multi scale,dynamic and interactivity meet the needs of the modern war on the perception of the characteristics of the regional terrain,digital maps has become an important topic of the national military research in recent years.The virtual battlefield environment compared with the traditional military map has many obvious advantages,especially in the background of the rapid development of computer technology.Though the army still use traditional paper-based military map as its first choice to perceived battlefield environment,it is far from being able to adapt to the full range of requirements of topographic information acquisition under the condition of high technology.The information construction of the army is advancing rapidly,and the technical level of the equipment has been improved constantly.In order to meet the needs of the local troops in the local terrain information,based on the existing conditions,this article use the traditional paper-based military topographic maps as data source,using computer image processing,computer pattern recognition and the theory of computer graphics,expound the data forms and characteristics of digital maps,the acquisition methods of the data of digital maps,the methods and techniques of digital processing the paper-based maps,the acquisition methods of DEM data,and the basic idea of using the DEM data to construct the virtual environment of the battlefield.The virtual battlefield environment support system discussed in this paper,focused on solving the bottleneck of staff in perceive the battlefield environment,change the original 2D military maps into a virtual 3D battlefield environment,in order to improve the combat capability of army and face the challenges under the new situation.
