多项式曲线拟合、三次样条曲线拟合、多项式曲面拟合、多面函数曲面拟合、移动法曲面拟合是全球定位测量水准拟合常用方法,本文结合实例,分析多种方法获得数据的精度,并通过工程实例比较和分析,认为移动法曲面拟合拟合法精度更高且稳定,具有较高的可靠性和实用价值。 更多还原

【Abstract】 Some common method for fitting the standard measurement of global positioning are polynomial curve fitting,cubic spline curve fitting,polynomial surface fitting,Multi-faceted function of surface fitting and mobile surface fitting method.Combining with practical example,this paper analyzed how to obtained the accuracy of the data by many ways,and with the compare and analysis for practical project,it believed that the method of mobile surface fitting’s precision is higher and more steady,and it h... 更多还原
