摘要
最小二乘估计方法和稳健估计方法广泛应用于测量学的各个领域中,两种方法各有优势。文中介绍了这两种方法并应用于水准网粗差探测和平差计算。计算结果表明稳健估计方法优于最小二乘估计方法,它不仅能准确探测粗差的位置,而且能剔除粗差,消除粗差对平差结果的影响,得到精确的平差结果。因此,在测量平差中应该用稳健估计方法进行平差计算,以便能得到更准确的结果。
The least-squares estimation and the robust estimation both with the advantages are used widely in surveying.In the paper,the author introduces the application of both methods in the gross error detection of the standard deviation and the adjustment calculation.The calculation results show that the robust estimation is better than the least square estimation.It not only detects accurately the position of the gross error,but also eliminates the gross error.It can get the precise adjustment results by eliminating the influence of the gross error.Therefore,the robust estimation method should be used in adjustment surveying to get more accurate results.
