-
摘要: 将Helmert方差分量估计理论进行优化后应用到形变监测网的数据处理中,使观测数据的权值更加合理,平差结果精度更高,更好地满足形变监测数据处理的要求。实例论证了优化后的Helmert方差分量估计方法的有效性。Abstract: As one method of the confirming weight newly to gain the best weight,Helmert variance component estination in used in many fields.In this paper,Optimized Helmert variance component estination is used in the deformation monitoring network,which makes the confirming weight more reasonable,and the adjusted value's precision much higher.It demonstrates the effectivity of Optimized Helmert variance component estination.
