集群目标跟踪在军事和民用领域有着广泛的应用需求。在大多数跟踪场景中,多目标通常被假定具有独立的运动并且良好分离。然而,对于集群目标跟踪问题,由于群内目标空间分布密集、协同运动、集群分裂或合并等复杂群结构变化以及群内目标数目多等因素,会导致更具挑战性的数据关联、滤波和计算上的问题。本文在信念传播算法框架下,通过联合推断目标存在变量、集群结构、数据关联和目标状态的分布,提出了一种可扩展的集群目标信念传播跟踪(GTBP)方法。在所提方法中,目标的运动建模为不同群结构下集群目标运动或单目标运动的交互,从而实现了集群目标和非群目标的无缝跟踪。此外,所提方法具有计算可扩展性的优点,其计算复杂度与保留的集群划分或传感器观测数目仅呈线性关系、与目标数目呈二次关系。仿真实验结果验证了集群目标信念传播跟踪方法的有效性和可扩展性,适用于大规模集群目标跟踪场景。
