宽刈幅多光谱遥感数据已经成为重要的数据源。如何使用商业遥感图像处理软件快速完成宽刈幅多光谱影像的正射纠正,得到了广泛关注。以北京一号小卫星多光谱影像为例,探讨了宽刈幅遥感影像正射纠正的技术方法,同时对比试验了基于通用推扫式模型(Generic Pushbroom Model,GPM)和有理函数模型(Rational Function Model,RFM)下正射纠正产品几何精度的影响因素。
The sensor with Ultra-Width has become an important data source. The method for utilizing the commercial remote sensing disposal software to accomplish the orthorectification of the remote sensing image with wide breadth has aroused much attention. BJ-1 small satellite multiple spectral images were used as an example to discuss the technology of orthorectification, and the influencing factors of the product’s geometrical precision using the Generic Pushbroom Model(GPM) and Rational Function Model(RFM) were also comparatively tested in this paper.
