一种面向移动GIS的运动对象位置预测方法

Location prediction method of moving objects for mobile GIS

提出一种基于GM(1,1)的灰预测模型,该模型不仅适用于满足线性函数关系的运动对象,而且能很好地支持自由运动对象,并在采样数据存在一定误差的情况下,可以很好地控制误差的传播,保持较高的预测精度.实验证明该模型相比于现有的线性预测模型具有更好的预测性能.

A novel grey prediction model based on GM（1,1）is presented.The grey prediction model is not only suitable for moving objects based on linear functions but also providing good support for free moving objects.In ad-dition,the grey prediction model can effectively control error propagation in circumstances of existing sampling error and ensure high prediction precision.The experimental results show the proposed grey prediction model has better prediction performances than the existing linear prediction models.
