Trajectory Modeling of Moving Objects Based in Spatio-Temporal Database
Jun Liu, Jing Wei Li · Advanced materials research · 2011
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 in actual application space and 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.
