| 摘 要： | 月球测绘是完成月球探测任务的基础保障。这里提出了一种适合于CE-1获取的CCD影像的多尺度约束自动匹配方法。首先利用SURF算子提取影像上特征点;然后进行基于准核线和最小欧式距离约束的影像匹配;最后采用随机采样算法对误匹配点进行剔除而得到同名点信息。实验结果表明,该匹配方法提取的同名点有利于CE-1月球影像DEM的生成。

| Abstract: | Lunar mapping is considered as the foundation of lunar exploration.A matching method for CE-1 CCD images based multi scale constraints was presented.Firstly,the feature points are extracted by SURF,then image matching is executed on the constraint condition of quasi-epipolar line and minimum Euclidean distance.At last random sample consensus is used to eliminate mis-matching points and the homologous information is obtained.The results of the experiments verified that the homologous points extracted by this method have more benefit for DEM generation. |
