摘　　要：在分析IKONOS卫星立体影像定位空间点方法的基础上,对传统方法进行合理简化并对实验数据进行分析,提出了一种快速获取人工地物高度信息的新方法。该方法避免了复杂的立体匹配过程,也不需要卫星内部参数信息,将此方法应用于卫星影像中典型地物如油罐高度的求取,结果真实可信。On the base of analyzing the method of positioning space point in Ikonos stereo image, the traditional method is simplified properly and the data is analyzed, a new method for acquiring the height information of manmade construction is proposed. In this method, complex process of image matching is avoided and interior parameters of the satellite become unnecessary. The method is applied in calculating the height of typical construction such as oil- tank in the satellite image, the result is believable.
