【摘要】 本文首先根据航空影像的获取过程和对极几何的约束条件给出计算变换参数的方程,然后用SUSAN(Smallest Univalue Segment Assimilating Nucleus)算子自动检测出两幅图像的角点并完成对应角点对的匹配,将角点对的坐标代入方程中,通过最小二乘法求出变换参数,最后根据变换参数对于图像进行纠正。更多还原

【Abstract】 The paper proposed a novel and simple method to align two areophotos, it is based the progression analysis of areophotos acquirement and constrain of epipolar geometry, By using SUSAN operator to calculate the corners ,and construction the correspondence of the corners from two images, then using the corners to calculate the transform parameters, finally rectification can be completed by using the parameters. The experiment proved the algorithm are efficient and robust.更多还原
