摘要
本文利用武汉测绘科技大学自行研制的摄影测量与非摄影测量观测值联合平差程序ＷｕＣＡＰＳ系统对天津蓟县某测区一组实际ＧＰＳ控制飞行的航摄像片进行了处理。针对ＧＰＳ辅助空中三角测量中的若干问题，如构架航线的敷设、地面控制点的布设、无地面控制空中三角测量的精度等，进行了研究。通过对测区进行ＧＰＳ辅助光束法区域网平差计算得到了与国外相同的研究结果。此外。
Abstract This paper describes some investigations on GPS supported aerotriangulation, such as the laying of control strip, the configuration of ground control points, the accuracy of GPS supported aerotriangulation without ground control points and others. A set of actual aerial photos with GPS camera position data taken from Tianjin's experimental project was used. The test was done by the use of combined adjustment program system for photogrammetric and non photogrammetric observations-WuCAPS developed by Wuhan Technical University of Surveying and Mapping. Some experimental results are derived from the calculation of the GPS supported bundle block adjustment. Our conclusion is same as the conclusion of related research in the world. In this paper, some useful suggestions for practical GPS supported aerotriangulation are presented.
