经典概括平差模型参数的两步解法

A two-step method for classical surveying adjustment

基于条件平差和间接平差的基本公式分两步导出了经典概括平差模型的解,并对解的结构进行分析,使两步解的各组成部分从形式上对应一种具体经典平差的解,从而彰显了概括平差的本质。

As we know,indirect adjustment model,indirect with constraint adjustment model,condition adjustment model,condition with parameters adjustment model belong to the classical adjustment model.To understand the relations of all classical adjustment models,Yu Zongchou has united the classical adjustment model by condition adjustment with constraints. To further understand the general adjustment model,not only has the solution of the general adjustment model been deduced based on the condition adjustment and indirect adjustment model but also has the all parts consisting of the solution been analyzed by supporting the solution meanings of other classical models,by which,the general adjustment model has a uniform in the model form as well as in the solution at the same time.
