摘要
本文依据广义立体像对的概念,利用覆盖同一区域的异源遥感数据分别作为左右影像,构建起该区域的广义立体像对,并以RFM模型为基础提出几种基于RFM的广义立体像对空间前方交会模型,结合现有影像数据,依次利用各空间前方交会模型进行地面三维坐标计算,进而针对各模型的计算精度进行了实验对比,并对精度影响因素进行了分析与探讨。最终证明了广义立体像对空间前方交会模型的计算精度能够满足遥感影像制图生产要求。
According to the concept of Generalized Stereopair, this paper constructed the generalized stereopair from the differ- ent-source high resolution remotely sensed imagery covering the same regions, and investigated several space intersection mathematics models based on RFM. Based on the available remotely sensed imagery, this paper separately calculated the ground 3D coordinates using these space intersection models, and compared the computing accuracies of these models, then analyzed and discussed the accuracy factors of them. Finally, it validated that the accuracy of generalized stereopair space intersection models could absolutely satisfy the requirement of mapping production from remotely sensed imagery.
