摘要: 针对数字化地图的精度,利用平稳随机过程的理论来估计位置数据的不确定性,提出了一套计算方法,主要内容包括运用平稳随机过程的各态历经性,对任意点坐标的X、Y按距离拟合求定其协方差,其特点是应用了统计估计原理,使得到的结果更为合理和简便。Abstract: Using the theory of stable random process to estimate the accuracy of data, this paper presents a method for calculation.For applying the principle of statistical estimation, its result is more reasonable and simple.
