Trajectory Modeling Of Moving Objects Based In Spatio-temporal Database And Rasearch On Index

Recently visual based action analysis of moving objects is a very popular field which is of much concern in computer vision. As the development of wireless technology and kinds of wireless applications, tracking and recording the location of mobile point the situation becomes possible. Movement prediction technology gets more and more attention.Now, mobile technology research is divided into two aspects: one uses user mobile history real time coordinates to make prediction, while the other only uses real time coordinates to make prediction.We should create trajectory model for mobile point, before setting up index structure of moving object trajectory. The purpose of this paper is to create the whole trajectory model of the Moving Objects position, and to solve some questions about Moving Objects on it, which are the trajectory update, predicting position, the index structure of moving object and to present a feasible solution.As a degree of one-sidedness about the current method of moving point trajectory modeling, it is one of the questions be solved how to establish the whole trajectory model, which will more efficiently support the past, present and future information processing. This paper first introduces the mobile some basic theoretical and track classification, then it says the mobile point the concepts and characteristics, mobile point of storage and management environment.In the text of the third chapter presents a new complete trajectory model.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 supporting the past, present and future information processing. It effectively predicts the moving objects of movement trend and scope at any time within the threshold. In order to effectively query the Moving Objects data, it is necessary to introduce effective index structure. The past index methods are commonly according to historical information. However, the index structures are less and their efficiency is low. In this paper the last chapter presents the common index structure, and emphatically introduced the mobile point index structures. It fully analyzes the advantages and disadvantages of the main index structure from the perspective of disposing the data of Moving Objects.
