Multi-source sensor box particle LMB filtering algorithm
随着复杂跟踪场景的大量涌现,常规多源传感器多目标跟踪算法存在计算量大、跟踪精度低、无法估计目标航迹等不足,已无法满足现代战争的需求.笔者以主动传感器和被动传感器组成的多源传感器系统为背景,重点研究多源传感器多目标跟踪问题的实现算法.针对"多主动+多被动"多源传感器系统量测无法充分融合且整体算法计算复杂度较高的问题,提出一种多源传感器箱粒子标签多伯努利(MS-BPF-LMB)滤波算法.首先,对传感器依据不同主动传感器进行分组,即将所有传感器划分为若干"单主动+多被动"传感器组;然后,通过并行运算,对各传感器组运用基于角度关联的多传感器信息融合算法,得到跟踪所需的有效量测;最后,在跟踪滤波阶段,通过引入箱粒子滤波数值计算方法,将获取的量测点划分为若干箱粒子,并对箱粒子滤波下的多传感器量测更新系数进行重新定义,以较低的计算复杂度实现LMB(Labeled multi-Bernoulli,LMB)滤波.仿真结果表明,所提算法在保证跟踪精度的前提下,误差明显降低且算法复杂度下降约 40%,能够有效处理异构数据多源信息融合问题.
With the emergence of a large number of complex tracking scenarios,conventional multi-source sensor multi-target tracking algorithms have shortcomings of high computational complexity,low tracking accuracy,and inability to estimate target trajectories,making them unable to meet the needs of modern warfare.In this paper,we focus on the implementation of the multi-source sensor tracking problem with the background of the multi-source sensor system composed of active and passive sensors.For the problem of a"multi-active+multi-passive"multi-source sensor system that the measurement cannot be fully integrated and the overall algorithm complexity is high,a multi-source sensor box particle labeled multi-Bernoulli(MS-BPF-LMB)filtering algorithm is proposed.First,the sensors are grouped according to different active sensors,i.e.,all sensors are divided into several"single active+multiple passive"sensor groups;and then,through parallel operations,a multi-sensor information fusion method based on angle correlation is applied to each sensor group to obtain the effective measurements required for tracking.Finally,in the tracking filtering stage,the obtained measurement points are divided into several box particles by introducing the box particle filtering numerical calculation method,and the update coefficients of multi-sensor measurements under box particle filtering are redefined to achieve LMB filtering with a low computational complexity.Simulation results show that the proposed method can effectively deal with the problem of multi-source information fusion of heterogeneous data by significantly reducing the error and decreasing the complexity of the algorithm by about 40% on the basis of maintaining the tracking accuracy of the target.
