摘　　要：本文以线阵卫星遥感影像为研究对象，定量地分析了基于有理函数的投影轨迹法核线模型的实际特性，重点就像幅范围内核曲线的近似直线特性和平行性进行了深入的探讨；在总结分析该影像核线特性的基础上，提出一种基于平行核线的核线影像生成方法。实验结果表明，该方法可以生成近似严格的核线影像。核线重采样之后，同名点的上下视差均被控制在子像素范围内。Taking the linear satellite remote sensing image as the research object, the paper quantitatively analyzed the features of the epipolar projection trajectory method based on the rational function, with an emphasis on the in - depth discussion about the approximate linear and parallel characteristics of epipolar curve in the frame of image. On the basis of a summary and analysis of the epipolar line feature, a new epipolar image generation method based on parallel epipolar is proposed. The experiment results show that the method can generate approximate rigorous epipolar image. Meanwhile, the vertical parallax of homologous image points can be controlled in the sub - image range after the resampling of epipolar line.
