摘要
介绍在无地面控制的情况下,采用将精密单点定位技术获取的摄站点坐标作为控制点进行光束法区域网平差的方法。并在SWDC数码航测系统支持下,结合桂林地区的航摄资料进行相关试验,试验结果表明,无地面控制的GPS辅助空中三角测量可以满足中小比例尺成图的加密要求。
The paper mainly introduces how to acquire 3D coordinates of Projection center with precise point positioning,and the method of precise point positioning technologies applied in GPS-supported bundle block adjustment without ground control.With the support of SWDC digital aerial system and the aerial data of Guilin,we do some relevant tests,and the experimental results show that GPS-supported aerotriangulation without ground control can satisfy the small scale cartography.
