浅谈地理国情普查影像制作、影像融合算法

伴随着地理国情普查项目的逐步开展，地理国情影像制作作为生产作业中重要的环节受到了高度重视。在此次项目中，采用的卫星影像共有4种，分别为Worldview-1，Worldview -2，Quickbird，资源三号，采用经过精细化DEM纠正的高分辨率全色影像加多光谱影像融合的方式生产最终的DOM数据。在融合过程中采用何种融合方法能达到最高生产效率与较高的生产质量受到一线生产人员的广泛关注，本文就这一问题加以分析，利用原理与实际生产给予解决。

Discussion China Geography Census Image Production Merge Algorithm

With the gradual development of China Geography Census , China Geography Census in image production as an important part of production operations by the very high priority .During this project, There are satellite images using four kinds , namely, Worldview-1,Worldview-2, Quickbird,ZY-3, using high-resolution panchromatic image through DEM corrected spectral image merge DOM way to produce the final data .What kind of merge process to achieve maximum productivity and high production quality production line staff received extensive attention , the paper made on this issue in order to analyze , using the principle of actual production to be solved .
