This paper proposes a novel particle filter tracking method based on simulated annealing(SAPF).The importance probability density function of particle filter is improved by using the simulated annealing method(SA).In order to expand the searching scope of particles,the amount of disturbance is introduced into the equation of state transition.According to the rule of Metropolis,the indigence is solved.At the same time,for moving particles to the high likelihood region,the temperature adjustment f...
