| 摘 要： | 针对一般地图数字化曲线拟合方法的不足,提出了利用附加系统参数平差计算拟合曲线的参数。在参数平差中,将数字化曲线的X坐标和Y坐标均看作观测值,综合处理偶然误差和系统误差的联合影响,并评定精度。用t分布对系统参数进行显著性检验,结果表明附加系统参数模型正确。

| Abstract: | The fitting methods of general digitized curve are insufficient,so this paper uses the additional system parameters adjustment to calculate parameters of fitting curve.In the parameter adjustment,X and Y coordinates of digitized curve are observations.This method deals with the influence of accidental errors and systematic errors,and it evaluates accuracy.Using t distribution to test system parameters,the results show that the model of additional system parameters is correct. |
