| 摘 要： | 本文研究利用测区前期的地形图来获取进行空中三角测量时所需的控制点三维坐标信息,对整个测区进行自动空中三角测量,获取每张像片的外方位元素,建立立体模型。然后在前期的数字高程模型(DEM)切割出对应模型的DEM,对像片进行数字微分纠正,获取每个模型正射影像。实验证明该方法的可行性。

| Abstract: | It is studied that the aerial triangulation surveying is auto-finished to whole area to get elements of exterior orientation of every photo and build stereoscopic model using topographic map to acquire 3D coordinates of control points.Then the corresponding DEM is cut from advance DEM,the photo is made digital differential rectification and the orthophoto map is get.Practice shows the method is feasibility. |
