摘　　要：针对某大型水电站水域面积较大、地形陡峭、人员难以企及、测图难度大的特点,利用WorldView3立体像对,通过优化像控点布点方案,改进立体像对处理流程,进行空中三角测量,完成立体测图。实验证明,其处理结果的精度较高,可以满足1∶2 000地形图的测图要求。As a large-scaled hydropower project features a large reservoir area,steep in topography,difficult to reach and map,the Worldview 3 stereo image is applied.By optimization of scheme for distribution of image control points and improvement of processing flow of the stereo images,the aerial triangle survey is performed and the stereo mapping is completed.The practice proves that the processing precision is higher and can satisfy the mapping requirement on 1∶2 000 topography.
