摘要
起算点的兼容性直接影响约束平差成果的质量,CPⅢ测量工作中要联测大量的已知点,区段搭接时要以重叠区段的部分上段成果作为约束点,因此,对起算点进行兼容性分析是十分重要和必要的。文中提出适用于CPⅢ网的平差起算点兼容性检验方法和兼容性较差起算数据探测方法,并在理论分析的基础上通过实测数据,计算分析并验证这些方法的合理性与科学性。
The compatibility of starting point directly affects the quality of constrained adjustment results.A large number of known points should be joint-measured in the work of CPⅢ surveying,and some points on the segment need to be involved adjustment calculation as constraint points,so the starting point compatibility testing is necessary and important.Some methods suitable for CP Ⅲ starting point adjustment network compatibility test methods and poor compatibility initial data detection are proposed,and through theoretical analysis on the basis of the measured data,these methods are proved to be feasible and scientific.
