结果表明,两种方案与“拟准检定法”具有相同的效果,具有粗差的观测值在平差时不起作用。
The results by these two approaches are the same as by QUAD(Quasi Accurate Detection), and the observations with gross error no longer affects the adjustment.
但在大坝视准线法不等精度观测中,由该基本定权公式推导的实用定权公式与测量平差书上的实用定权公式不一致。
But the practical formula for deciding weight derived from this basic formula is different from tha written in the books of survey adjustment.
总体最小二乘方法(TLS)是近年来出现的一种较新的平差方法,与传统最小二乘方法(LS)不同的是,TLS可以同时顾及系数矩阵及观测值的误差。
The total least squares (TLS) are a new method in adjustment in recent years. Different from the least squares (LS), the errors in coefficient matrix and observations are considered simultaneously.
