摘　　要：本文针对线阵推扫式卫星影像，利用有理函数的传感器模型建立了投影轨迹法核线模型；并通过两种代表性的遥感影像数据，定量分析了该模型核曲线的应用特性，包括近似直线特性以及平行性。试验结果表明，线阵推扫式卫星立体像对的核线模型在像幅范围内可以近似看作直线，这一特性将为后续基于投影轨迹法核线模型实现核线影像的生成奠定基础。For the linear push - broom satellite imagery, this paper builds a projection track epipolar model with RFM. Meanwhile, the authors quantitatively analyze the application quality of epiploar curve, including straight line fitting quality and parallel quality based on the two typical remote sensing image data. The experimental results show that the epipolarity for linear array satellite images can be regarded as a straight line within the image frame, which lays the foundation for the generation of epipolar images based on the projection track epipolar model.
