浅谈正射影像图的制作

摘要

正射影像图,以其直观准确地反应地形地貌、制作周期短等特点,越来越广泛地应用在空间地理信息建设中.正射影像图是按照地理坐标生成的具有严格几何精度和影像特征的数字地图,也是4D产品中的重要组成部分.本文浅谈利用Virtuoz0 3.7.5代替以前Virtuoz0 3.24-Virtuoz0 3.5等低版本方便快捷地进行影像制作的方法和过程.%Orthophoto map is applied more and more widely in the construction of geographic information due to its accuracy in reflecting natural topography and its short term of production. Orthophoto map is a digital map with high geometric accuracy and distinct image features rendered according to geographic coordination, and also an important part of the 4D products. This paper demonstrates briefly on quick image production using Virtuozo 3.7.5 instead of earlier 3. 24 - 3. 5 versions, which is fast and easy.
