摘要
本文针对数字化地图的曲线拟合精度进行了研究 ,提出了评定拟合质量的标准和计算方法。主要内容包括综合考虑拟合的模型误差和偶然误差的联合影响 ,论证了拟合方程优选的标准 ,给出了选模的实用方法 ,导出了模型误差的区间估计式以及拟合结果的不确定度公式 ,最后进行了实例验证。
This paper deals with the precision of curve fitting for digitizing map.The evaluation standards and curve fitting methods are introduced.The main concerns are related to unite infection of systematic error and accidental ones.The selected standards are demonstrated and the applied methods given for the selected model.Finally the formula of uncertainty for systematic error resultant is also derived here.
