Báo Cáo Ground mobile target tracking by hidden markov model

Abstract
​

In recent few years, there are many researches of finding the efficient method for tracking moving objects using some fundamental and traditional instruments such as GPS, video camera, The most important task is to find out the accompanying algorithm to realise this tracking with a better precision. In this paper, an algorithm based on
Hidden Markov Model (HMM) for ground mobile target tracking is introduced. The HMM is a good choice for modelling moving process because of its character in modelling sequential processes. Suppose the moving object is on a known ground plane and theHMM parameters are the motion capture data (position, speed, steering angle, ). Once the HMM for the target motion has been constructed, the Viterbi algorithm is applied to find the trajectory of the target. Some illustrating results in modelling a moving target (for instance, a mobile cell phone) will be presented.

Keywords: Hidden Markov model, target tracking, Viterbi algorithm, observation,sensor.
