摘要
在推出边角后方交会简捷精度估算式的基础上 ,分析并给出了待定点较优的选择区域 ,还讨论了其解的多值性问题及实质 ;针对边角后方交会应用中有较严格的布点限制 ,提出了双边单角后方交会的布设方案 ;文中给出了其点位与精度计算的固定公式 ,并附有实例验证。
This paper firstly derives the simple formula of precision estimation for side angle resection, then analyses and gives the optimum layout areas of unknown point. It also discusses the problems about multi value solution. Aming at the fact that the side angle resection possesses the problems of strict layout restriction, the author proposes the layout scheme of two side and one angle resection, the fixed formulae for position and precision are presented. At last, an example is attached.
