摘要
本文以现代统计理论中的Bayes原理为基础,探讨如何在变形网平差与变形分析过程中利用变形的先验信息,建立考虑先验信息的平差模型,推导有关平差公式,然后探讨确定先验分布的方法,最后用一实例显示了该方法的可行性。
Based on the Bayes principle of modern statistics theory, this paper discusses the utilization of prior information in the deformation network adjustment and analysis. The paper first establishes the adjustment model considering prior information,derives the related adjustment formulae, then discusses the method of determining the prior distribution. Finally, a case history is given to manifest the feasibility of the method.
