Research on moving object tracking based on Markov model
The existing localization algorithms just only shows the static location features of the target,it can not be better to track to get the trajectory of the operation behavior in the mobile condition.This paper designs a trajectory target tracking algorithm based on Hidden Markov model.Firstly,based on the location information of the coverage area of the cell(including roads and subsection,the base station location) movement speed of the target,to construct the topology of actual highway for the restore problems of behavior trajectory,and calculate the transfer matrix between each section of highway; then,established a hidden Markov model; then,based on the Vitby decoding algorithm to take the most optimal solution of the probability of the best path and the best condition,to achieve the tracking of target,and then recover the target trajectory.The simulation results show that,the algorithm can accurately obtain motion track of the target in the resolution ratio of station cell.
