| 摘 要： | 介绍了利用左右正射影像上高层建筑物存留的投影差,形成立体,在正射影像立体观察的环境下,推导出一套对地物进行三维量测的公式。实验表明,该公式严密准确,不仅可以使用户直观地检查DEM的正确与否,而且可以实时地获取地物的三维坐标,以大大减少用户对于向量的需求。

| Abstract: | The paper introduces an approach for measuring 3D objects by using an ortho image pair. A set of formulas is proposed to calculate the coordinates of a point of 3D object,in which the remain parallex is used to form a stereo vision. The experiment proved that the formulas are accurate and usable. It can be used for DEM data checking, and it is easy to get 3D coordinates of objects dynamically. This could be a new method for 3D vision systems to get the 3D coordinates of an object directly. |
