介绍了高分辨率商用卫星遥感影像正射处理的一般原理及方法,对不同的布点方案下的DOM纠正精度进行分析,以提高正射影像生产的精度及生产效率。同时,针对DOM现势性不够以及特殊区域的扭曲变形问题,探索进行DEM技术修复的方法,从而提高DOM产品的成图质量,在DOM生产中具有重要的实际应用价值。 更多还原

【Abstract】 The paper introduced the general geometrical model and techniques about the ortho-rectification of high resolution image,and discussed the precision of the DOM based on different distribution of control points in order to improve not only the precision of orthophoto map but also the production efficiency.Furthermore,the paper explored a method with topographic correction to solve the distortion and deformation caused by DEM,so that to improve the quality of DOM data. 更多还原
