带权约束参数平差法及其应用

Method of Parameters Adjustment by Weighted Constraint and Its Application

利用相关平差的原理，把已知点（高级点）的坐标，看作是由具有先验方差──协方差矩阵的观测量引入平差模型．从而扩展了高斯－马尔可夫模型，使它能适用于各种测量控制网的平差计算，并能解释和包含各种平差方法。使多种测量平差模型归于同一模型─—带权约束参数平差模型．

In this paper the theory of correlative adjustment is used.The coordinates of known points are regarded as observations with a priori variance-covariance matrix by which the Gauss-Maleav Model is extended to involve all kinds of control network adjustment and to make explanations.The varied adjustment model can ho reduced to the model of the weighted constraintparameters adjustment.
