摘要
主要以1:500地形图为无人飞行器遥感影像处理的辅助数据源,提取地形图点坐标作为外业控制点,进行单模型绝对定向和光束法空中三角测量及地形图修测和补测实验。通过实验论证了1:500地形图用于无人飞行器遥感影像的辅助处理是可行的,并给出了从DLG提取控制的规范和影像定向处理的方法。
By mainly using 1:500 DLG as the auxiliary data resource for processing remote images of UAVRS,and extracting points' coordinates from DLG as the control points of field surveying,in this paper we explored the possibilities of single model absolute orientation,bundle aerotriangulation,as well as the experiments of revision and supplementary survey of the relief map.Experiments demonstrated that it is feasible to use 1:500 DLG in auxiliary processing of remote sensing images of UAVRS.The standard of extracting control points form DLG and the method of image orientation processing were given as well.
