控制网间接平差近似坐标推算的研究

Study on Calculating Approximate Coordinate of Control Network Using Parameter Adjustment

在控制网间接平差中,控制点的近似坐标推算是需要解决的首要问题。控制网中已知数据的类型决定了推算方法或者推算步骤。目前无论在教学中还是工程实践中,对近似坐标的推算问题还存在模糊的认识,在解决较为复杂的控制网间接平差问题时,由于没有搞清楚近似坐标推算的基本思路和方法,往往不能顺利的解算出近似坐标。文中通过推算流程图和具体例子详细阐述了具有必要起算数据的单一推算类型的控制网近似坐标的推算方法,有助于澄清概念,解决控制网近似坐标推算的计算机程序设计问题。

On the procedures of parameter adjustment in a control network, the first thing needs addressing is calculating approximate coordinate and the procedure and method determined by given data. Currently, whatever in teaching and engineering practice, there are some vague concept in this issue. When the control network is complicated, being due to not understand the fundamental concepts and methods about this topic, it is not easy to calculate approximate coordinate. It illustrates the methods and procedures to solve this problem by using flowcharts and examples in the control network which has enough given data with single deducing method in this paper. It can contribute to clarify the concept and address the problem of computer program design.
