| 摘 要： | 采用一组带ＧＰＳ导航数据的实际航摄资料，通过平差计算出精度矩阵Ｑｘｘ的数值，对ＧＰＳ辅助光束法平差的理论精度变化规律进行了全面讨论。以此为基础，从理论上给出最佳区域网的大小、地面控制点的布设等实用技术要求。此外，还探讨了ＧＰＳ用于单航线航空摄影测量加密的可行性和具体实施方案。

| Abstract: | This paper selects a set of actual aerial photographs with the camera position determined by GPS kinematic positioning, and analyzes the theoretical accuracy of GPS supported bundle adjustment by calculating the accuracy matrix Q xx . The block range and the arrangement of ground control points for GPS supported bundle adjustment were given based on the above experimental results. In addition, the GPS application feasibility and method on GPS supported adjustment by single strip were discussed. |
