【摘要】 在野外数据采集过程中,时常会遇到由控制点数据错误产生测点位置错误问题。总结分析了可能出现的多种情况,归纳出了错误的类型。并且提出了采用距离交会算法对测点坐标进行改正的新方法,导出坐标数据改正的数学模型,总结出了用一种数学模型解决控制点坐标有误、无控制点坐标等多种错误类型的测点坐标改正方法及其注意事项。并用VC++编写了相应的程序工具,经实验数据验证了它的可行性和正确性。该方法的提出和应用,可提高外业测绘工作的效率,具有较高的实际应用价值。更多还原

【Abstract】 As you are plotting in the open air,you must fall across the circs of control points,which are wrong.As they are wrong,lead to the survey point position error.To these problems,the article make the analysis manifold circs and sum up the wrong type.And I deduce mathematical model of corrected coordinates data,about confused coordinates,with distance intersection arithmetic this new technique.By the above method,you can use one mathematical model to solve survey point coordinate error about control points which are wrong,even no control points,manifold error types and so on.I also give you the list concerning notice proceeding.I used Visual C++ program the software,and also combine the experimental data confirm the validity of arithmetic.The method which is brought forward and applied can enhance efficiency of mapping work,and also has upper actual application merit.更多还原
