中文摘要：

针对核线影像无几何模型的问题，提出基于有理多项式系数（Rational Polynomial Coefficient，RPC）模型，利用投影轨迹法制作线阵推扫式卫星核线影像及其几何模型的重建方法。利用SPOT5HRG、CBERS2—03异轨立体像对和SPOT5HRS、IRSP5、GeoEye、IKONOS同轨立体像对重建的核线影像几何模型土下视差的中误差在0．2个像元之内；利用重建几何模型和原始影像几何模型进行前方交会计算所得到的地面点平面中误差在1m之内，高程中误差在0．3m之内，验证了本文方法的可靠性。

英文摘要：

In view of the nonexistence of geometric model for epipolar image, this paper, based on the RPC model, puts forward a practical way of building geometric model from epipolar image generated by the projection track method. With the support of across - track stereo image data of SPOT 5 HRG, CBERS 2 - 03 and along - track stereo image data of SPOT 5 HRS, PS, GeoEye, IKONOS, this paper indicates that the RMS of vertical parallax of the epipolar image is within 0.2 pixel, that the planar RMS calculated from forward intersection by the epipolar model and the original image model is within 1 m, and that the altitude RMS is within 0.3 m.
