附不等式约束平差的理论与方法研究

Research on theory and methods of inequality constrained least squares

附不等式约束平差能充分利用已有的各种知识和信息,因而越来越得到关注,它在GPS数据处理、变形监测及方差估计等领域中都得到广泛的应用。目前,国内外对附不等式约束平差问题进行大量研究,文中主要综述附不等式约束平差问题的最新研究成果,系统介绍附不等式约束平差的理论,同时探讨附不等式约束平差的发展方向。

The inequality constrained least square can make full use of many kinds of prior knowledge and information and has wide application in GPS data processing, deformation monitoring and variance components estimation. Nowadays, in China and abroad, there are many studies on the inequality constrained least square. The paper reviews the research activities and development in studies of inequality constrained least square, introduces its solution and features in operational research and geodesy data processing, and gives some suggestion for its further studies.
