A target tracking method with box-particle generalized label multi-Bernoulli filtering(Box-GLMB)is proposed to address the problem that the sequential Monte Carlo generalized label multi-Bernoulli filter(SMC-GLMB)has low computation efficiency and weak real-time performance. A random finite set with labels is employed to describe states of multi-targets
including positions and velocities of targets
and targets are distinguished by different labels. Then the box-particle filter algorithm is used to approximate the probability density of single target
that is
the probability density of single target is approximated by weighted uniform distributions. Multi-target densities are predicted and updated by using the generalized label multi-Bernoulli filter(GLMB). Target states are estimated from posterior probability density and trajectories of targets are tracked by labels. The proposed method combines the advantages of the box-particle filter and the generalized label multi-Bernoulli filter. Box-GLMB filter is able to track trajectories and to improve computational efficiency at the same time. Simulation results show that the proposed filter effectively estimate states of targets and track trajectories. A comparison with the SMC-GLMB filter show that the proposed filter increases 62% computational efficiency.
