战场地理信息系统中遥感图像处理和三维综合建模技术研究
摘要
随着21世纪世界新军事变革的不断升级,迫切需要建立辅助配合高技术条件下局部作战,与作战地形、作战地理要素密切关联的信息系统,这就是战场地理信息系统。战场地理信息系统处理、管理的对象是作战地理空间实体数据,包括空间定位数据、图形数据、遥感图像数据、属性数据等,用于分析在一定地理区域内分布的各种现象和过程,解决复杂的决策和管理问题。
本文重点对战场地理信息系统中,遥感图像处理及快速浏览、影像与地图的配准纠正、影像数据的分快技术、金字塔技术、显示技术,三维场景构建、数据动态管理的基本思想、基于矢量地图数据生成地表纹理、地物模型的建模和处理等技术进行研究与探讨。
As military reform has been continuously upgrading in the 21st century globally, it is urgent to set up an information system, which assists and cooperates with brushfire in high-tech conditions, and is also closely relative to terrains and geographic elements of a battle. This system is called geographic information system of battlefield. Its target is to process and manage the estimative data of a battle' s geographic space. These data include dimensional orientation data, graphics data, remote-sensing image data and properties data. They are used to analyze various phenomena and process within a certain geographic zone, and resolve complex problems in decision-making and management aspects.
This paper focuses on the research and discussion of some technologies within the geographic information system of battlefield. These technologies include processing of remote sensing image, speed browsing, adjusting and correcting videos and maps, classifying image data, pyramid technology, display technology, the basic thoughts of constructing three-dimensional scenes and dynamic management of data, as well as modeling and processing models of ground objects.
