中测广域平差法
|
摘要
针对测量平差应用问题,该文用条件平差观点讨论中测广域平差法。用对比方法推导广域间接平差、附条件式广域间接平差、广域条件平差和带未知数广域条件平差4种测量平差方案的数学模型,总结其求解规律,给出求解通式,方便读者在工作中掌握、应用。文中附有算例,说明中测广域平差法用于实践比传统方法优越,精度稳定,可信度较高。研究结果可为相关人员提供参考。
Aiming at the application of surveying adjustment,this paper discusses the CS wide-area adjustment method from the viewpoint of conditional adjustment.Mathematical models of four schemes of wide-area indirect adjustment,conditional wide-area indirect adjustment,wide-area conditional adjustment and wide-area conditional adjustment with unknown number are derived by comparison method.Summarize the law of its solution,and give the general solution formula,which is convenient for readers to master and apply in their work.Some examples in this paper show that the wide-area adjustment method is superior to the traditional method in practice,with stable accuracy and high reliability.The research results can provide reference for the relevant personnel.
