摘　　要：为了解决高分辨率遥感影像的定位和正射纠正问题,在对包括多项式模型、直接线性变换模型和有理函数模型在内的通用传感器模型进行简单介绍的基础上,对基于通用传感器模型的高分辨率遥感影像的单片定位和正射纠正方法进行了理论和实验研究,并对实验结果进行了比较和分析。实验表明,利用符合影像变形规律的通用传感器模型进行单片定位和正射纠正,可以得到理想的精度。To resolve the problem of positioning and ortho-rectification for single high-resolution image, this paper introduces approximate sensor models including polynomial model, direct linear model and rational function model. On this basis, researches on the theory of positioning and ortho-rectification for single high-resolution image and corresponding experiments are carried out, The experimental results are analyzed. The conclusion is drawn that satisfactory accuracy can be gained by using approximate sensor model in accordance with the deformation of image in the process of positioning and ortho-rectification.
