Theoretical Accuracy for GPS-Supported Bundle Adjustment

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Q_xx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.
