摘要: 摘 要:提出一种基于有理多项式模型(RFM)进行高分辨率卫星遥感影像自动匹配的方法。首先利用RFM进行高分辨率卫星影像直接定位和同名点预测;然后基于投影轨迹建立近似核线方程,并分析了核线精度;接着采用金字塔影像策略进行核线约束的近似一维影像匹配,并经最小二乘影像匹配精化匹配结果;最后采用RANSAC算法剔除误匹配点以获取最终的匹配结果。通过与二维灰度相关方法和SIFT匹配方法的比较试验,证明本文方法可靠性好、匹配成功率高,较好地解决了多时相、大姿态角高分辨率卫星遥感影像的自动匹配难题。

Abstract: Abstract: A matching method for high resolution satellite images based on RFM is presented. Firstly the RFM parameters are used to predict the initial parallax of corresponding points. Secondly the approximate epipolar equation is constructed based on projection tracking and its accuracy is analyzed. Thirdly approximate 1D image matching is executed on pyramid images and least square matching on base images. At last RANSAC is imbedded to eliminate mis-matching points and matching results are obtained. Test results verified the method robust and with high matching rate, compared to 2D gray correlation method and SIFT matching method, and solved the question of high resolution satellite image matching with different time and large rotation images.
