战场环境可视化中多源遥感影像数据处理

The Processing Methods on Multi-Sensors RS Image Data for Virtual Battle Space Visualization

介绍了将多源遥感影像数据应用于战场环境可视化之前的主要预处理方法,如影像金字塔生成、纹理数据结构准备、纹理快速调用等。该过程中所用到的小波变换、四叉树数据结构与细节层次算法等关键技术,能够有效地提高战场建模的真实感和效率。

This paper mainly introduces some key pre-processing methods on multi-sensors remote sensing image data for virtual battle space visualization, such as creating pyramid image structure, preparing the data of texture and fast loading the texture. Texture factor will uniformly integrate with terrain character and 3D rendering speech will be improved due to the pivotal technology used in the process like wavelet-transform, quadtrees data structure and LOD algorithmwavelet-transform, quadtrees data structure and LOD algorithm.
