测量平差中参数初值重要性的研究
Importance of initial parameter values in surveying adjustment
摘要
Abstract
This research addresses the selection of initial parameter values in surveying adjustment processes,particularly during the linearization of non-linear models,and explores the impact of different initial values.By using an example of tra-verse network adjustment,two methods were employed to select different initial values for the adjustment,followed by a comparative analysis of the adjustment results based on these initial parameters.The findings indicate that different initial parameter values yield varying adjustment results,as well as different numbers of iterations in the adjustment process.The conclusions drawn from this study hold significance for the selection of initial parameter values.关键词
