该文在简要介绍GPS辅助空中三角测量和全数字自动空中三角测量的基础上,详述GPS与全数字化摄影测量结合的产物——GPS辅助全自动空中三角测量的基本原理、方法和作业流程。介绍几个用到的软件系统,分析讨论哈尔滨测区的试验结果及新方法与常规方法在精度和效率上的对比,试验充分证明了GPS辅助全自动空中三角测量的先进性和在航空遥感定位中的广阔应用前景。

After an overview of the GPS supported Aerotriangulation and the Fully Automatic Aerotriangulation, this paper presents the GPS supported Automatic Aerotriangulation, including itsprinciple, method and procedure. The related software developed by the authors are briefly described. To test the new method suggested by the authors, a real data set of GPS supported aerophotography taken from Haerbin project was used. The results of the test indicates that the new method will increase the accuracy and the efficiency very significantly and the new method can be widely used in GIS data acquisition and updating.
