摘要
根据遥感影像正射影像图制作的实践和经验,以如何快速获取高精度的正射影像图为目标,分别采用多项式模型、有理函数模型和严格物理模型三种方法对实验区域进行正射纠正处理,并从几何精度和效率方面对不同方法进行比较和分析,探讨快速获取高精度正射影像图的方法。
Based on the practiee and experience of making the remote sensing orthophoto maps, this paper focuses on stud- ying how to obtain the high-precision orthophoto maps. The experimental areas are orthorectified by adopting the polynomial model, rational function model and rigorous physical model, respectively. Furthermore, the different methods of those three models are compared and analyzed through both the aspects of geometric accuracy and efficiency, in order to quickly gain the high-precision orthophoto maps.
