摘要
通过对光束法区域网平差理论对平面和高程精度的分析,和近几年相关数码航空摄影测区的实际应用,采用MAP-AT自动空三测量软件在同一区域使用不同的像片控制点布设方案,分别进行空三平差,并比较检测点的坐标变化,研究不同的布点方案对量测点平面和高程精度的影响,最后得出了一些像控点布设方面的初步建议。
Through analyzing theories of bundle block adjustment for plane and elevation precision,and actual applying in photogrammetry surveying in recent years,use MAP-AT automatic aerial triangulation software in one surveying area with different distribution methods,and adjust differently.With comparing changes of coordinates,analyze influences for different distribution methods in plane and elevation precision.Finally,we get conclusions for control points distributions for anybody else working in this area.
