摘要
大区域虚拟战场环境研究需用大规模的数据源作为实验数据,其中数字高程模型数据和相应的彩色影像数据是2种重要的数据源,但这些数据源售价较高,远非一般研究单位所能承受;提出了一种由小范围数据源模拟大范围数据源的无缝翻转法和一种用灰度影像数据模拟彩色影像数据的方法.前者解决了当前放大方法不能实现无缝拼接的问题,后者实现了将灰度图转换成彩色图.这2种方法可为大区域虚拟战场环境研究提供满足实验要求的大规模数字高程模型和彩色影像数据.
Large scale data sources are needed as experiment data in the research of large area virtual battlefield environment. Large scale DEM(Digital Elevation Model) data and corresponding color texture images are two kinds of important data sources. But the price of those data sources is so high that the common research departments cannot afford it. In this paper, a method is proposed to simulate large scale data sources using little scale data sources. The corresponding color texture images are simulated by grey images. The former method solve the problem of put lots of images together without sew that the current magnifying method can't solve. The later can turn the grey images into color image. This two different methods can provide large scale DEM data and the corresponding color images for the research of large area virtual battlefield environment.
