摘要
从非线性平差精度评定的理论基础出发,综述目前两类精度评定方法的研究现状,描述相应方法的基本原理,分析每种方法的优缺点与适用性,并对非线性平差精度评定的未来研究方向进行展望。
Starting from the theoretical basis of nonlinear adjustment precision evaluation,we review the current research status of the two types of precision evaluation methods.We describe the basic principles of the corresponding method and analyze the advantages and disadvantages of each method.In addition,we look forward to the research direction of nonlinear adjustment precision evaluation.
