| 摘 要： | 实现遥感影像的2维可视化动态漫游则可以从不同的视角以不同的速度对地面信息进行观察,以实现重复再现和分析的效果。实现漫游首先要从遥感影像中提取特定的地理信息,并对特定投影的遥感影像进行坐标转换后逐帧绘制。本文利用对UTM投影的GeoTIFF卫星像片进行3维坐标转换,并实现第一和第三人称的3维漫游。

| Abstract: | It is beneficial to observe the ground information in different way and visual angle by diverse speed,and realize the representation and analysis effect with the realization of 3D visualization dynamic roaming.It extracts the geographic information from image and transforms the coordinate for special projection before rending them by frame to realize the roaming.This paper achieved the 3D coordinate transformation for the satellite image of GeoTIFF format using UTM projection,and realized the 3D roaming to first person view and third person view. |
