| 摘 要： | 在传统海洋航空摄影测量中,由于外业控制点和航线连接点的选取困难,使大比例尺独立岛屿的测量精度无法保证.将IMU/DGPS在海洋航空摄影测量中加以运用,通过无控或稀少控制的辅助空中三角测量解算方法,探讨在大比例尺独立岛屿测量中的控制点布设要求,为海岛(礁)的外业控制点布设提供参考.

| Abstract: | In the traditional marine aerial photography,due to the field control points and connection points of the route selection difficulties and large-scale independent islands of measurement accuracy is not guaranteed.Based the IMU/DGPS survey of aerial photography to the use of technology in the ocean,through no control or control of scarce auxiliary aerial triangulation,discussion on control point Principle of large scale independent island requirements,for the islands（reef） outside industry control planning to provide reference. |

| Keywords: | IMU/DGPS independent island auxiliary aerial triangulation control point |
