基于距离交会原理的测点数据纠正新方法

Survey point data correcting technique based on distance intersection principle

在内业成图时,时常遇到在数据采集过程中由于控制点数据错误导致测点位置错误的问题。对比此类问题,提出了采用距离交会算法对测点坐标进行改正的新方法。推导并总结出用一种数学模型解决控制点坐标有误,甚至无控制点坐标等多种情况下的测点坐标改正方法及其注意事项,并用VC编写了相应的工具软件,经实验数据测试,验证了它的可行性与正确性,为测绘生产单位提供了解决上述问题的一种新途径。

As you are drawing in doors, you must fall across the error of control points. As they are wrong, lead to the survey point position error when you collect data. The article brings forward distance intersection arithmetic to correct coordinates data. And we also deduce and summarize using one mathematical model to solve survey point coordinate error about control points, even no control points, manifold error types and so on. We also give the list concerning notice proceeding. We used Visual C ＋ ＋ program the software, and combined the experimental data which confirm the validity of arithmetic. At last, this new technique provides a new way of solving above problem for the survey production corporation.
