时空数据库移动点轨迹建模

Trajectory Modeling of Moving Objects Based on Spatio-Temporal Database

时空数据库的移动点轨迹建模技术是近年来是时空数据库研究热点之一。本文在给定一系列时空数据库移动点的信息,找出实际应用中时间更新阈值和空间距离阈值,结合移动点时空模型和数学上线性回归的建模思想,建立一种新的支持过去、现在、未来的移动点轨迹模型,并有效地预测了移动点在某一时间阈值内,移动点的运动趋势及范围。

Trajectory modeling of moving objects is one of the key problems in spatio-tempo-ral databases research.In a series of moves spatio-temporal database information and finding time to update threshold in actual application and space threshold distance threshold,this paper combines the ideas of the linear regression model in mathematics to propose the trajectory model,which is on the basis of the Moving Objects Spatio-Temporal model and supports the past,present and future information processing.It effectively predicts the moving objects of movement trend and scope at any time within the threshold.
