Through analyses of epipolarity geometry of the linear ccd push-broom images and frame perspective images, based on the projection track method, epipolarity of linear ccd push-broom image is established and the properties of epipolarity curves is discussed, and a new epipolarity model based on the simplified push-broom sensor model is proposed . for stereo images of frame perspective and linear perspective, how to set up of epipolarity is studied in terms of fundamental matrix in computer vision, and an algorithm of epipolarity solution that only depends on coordinates relation of identical point is presented . 4 通过线阵ccd推扫式影像和框幅式中心投影影像核线理论的对比研究,利用投影轨迹法建立了线阵ccd推扫式影像的核线模型,分析和总结了它的基本特性;针对基于共线方程的简化传感器模型,提出了一种新的核线模型;对框幅式中心投影立体影像和线阵ccd推扫式立体影像,利用计算机视觉中的基本矩阵研究核线关系的建立,提出了一种单纯依靠同名点坐标关系的核线模型解法;4
