摘要:

针对具有不同视野的传感器的分布式多目标跟踪问题,本文提出了一种基于本地测量生成后验概率假说密度(PHDs)的融合方法。所提出的方法结合了广义协方差交集(GCI)规则与合适的聚类算法(CA),用于将每个后验PHD分解为良好分离的组件(聚类)。对于通常检测到的目标,提出了一种高效的并行化GCI融合策略,并在$ L_1 $误差分析中进行分析。对于剩余的目标,采用合适的补偿策略以抵消GCI对独立检测的敏感性,同时减少虚假目标的发生。详细提供了使用高斯混合(GM)表示PHDs的实现步骤。数值实验清楚地证实了所提出CA-GCI融合算法的有效性。

英文摘要:

Distributed multi-target tracking (DMTT) is addressed for sensors having different fields of view (FoVs). The proposed approach is based on the idea of fusing the posterior Probability Hypotheses Densities (PHDs) generated by the sensors on the basis of the local measurements. An efficient and robust distributed fusion algorithm combining the Generalized Covariance Intersection (GCI) rule with a suitable Clustering Algorithm (CA) is proposed. The CA is used to decompose each posterior PHD into well-separated components (clusters). For the commonly detected targets, an efficient parallelized GCI fusion strategy is proposed and analyzed in terms of $L_1$ error. For the remaining targets, a suitable compensation strategy is adopted so as to counteract the GCI sensitivity to independent detections while reducing the occurrence of false targets. Detailed implementation steps using a Gaussian Mixture (GM) representation of the PHDs are provided. Numerical experiments clearly confirms the effectiveness of the proposed CA-GCI fusion algorithm.
