嫦娥二号影像密集匹配及DEM制作方法
|
Abstract:
嫦娥二号卫星搭载了一台两线阵CCD立体相机，以线阵推扫成像方式获取了覆盖全月球的7 m分辨率影像。与嫦娥一号影像相比，影像分辨率大大提高，月表地貌细节更加丰富，制作高分辨率月表DEM更加复杂而困难，现有的基于嫦娥影像制作方法难以满足应用需求。针对嫦娥二号影像特点，在基于RPC模型生成近似核线影像基础上，进行金字塔影像匹配，实现了原始影像的逐像素匹配；计算匹配点的月面坐标后，采用基于反距离插值方法生成月表三维地形；对于图像阴影等地形漏洞，采用基于径向基函数进行插值填补。试验结果表明，该方法生成的月表三维地形DEM数据，能准确真实地表达高分辨率的月表地形地貌细节，并较好地应用于嫦娥二号全月球三维地形DEM数据产品的生产任务中
