【摘要】 根据GPS高程拟合中不同拟合模型的特点,利用多面函数较好的整体拟合性和移动法灵活的局部拟合性,提出了一种基于多面函数和移动法的综合模型。3种不同地形的算例表明,本文提出的综合模型在不同地形条件下较其他两种综合模型拟合效果更好,即拟合精度更高,残差更稳定。更多还原

【Abstract】 According to the characteristics of different fitting models in GPS height fitting,a synthetic model is created which combines a better overall fitting of multi-surface function and a flexible partial fitting of movement method. The synthetic model of this paper has a better fitting effect with higher precision and more stable error comparing with other two synthetic methods in three different terrain conditions.更多还原
