Most multi-target movements are nonlinear in the process of movement. The common multi-target tracking filtering methods directly act on the multi-target tracking system of nonlinear targets, and the fusion effect is worse under the influence of different perspectives. Aiming to determine the influence of different perspectives on the fusion accuracy of multi-sensor tracking in the process of target tracking, this paper studies the multi-target tracking fusion strategy of a nonlinear system with different perspectives. A GM-JMNS-CPHD fusion technique is introduced for random outlier selection in multi-target tracking, leveraging sensors with limited views. By employing boundary segmentation from distinct perspectives, the posterior intensity function undergoes decomposition into multiple sub-intensities through SOS clustering. The distribution of target numbers within the respective regions is then characterized by the multi-Bernoulli reconstruction cardinal distribution. Simulation outcomes demonstrate the robustness and efficacy of this approach. In comparison to other algorithms, this method exhibits enhanced robustness even amidst a decreased detection probability and heightened clutter rates.
大多数多目标运动在运动过程中是非线性的。常见的多目标跟踪滤波方法直接作用于非线性目标的多目标跟踪系统,在不同视角的影响下融合效果较差。为了确定目标跟踪过程中不同视角对多传感器跟踪融合精度的影响,本文研究了具有不同视角的非线性系统的多目标跟踪融合策略。引入了一种GM-JMNS-CPHD融合技术,用于在多目标跟踪中进行随机离群值选择,利用视野有限的传感器。通过从不同视角进行边界分割,后验强度函数通过SOS聚类分解为多个子强度。然后用多伯努利重构基数分布来表征各个区域内目标数量的分布。仿真结果证明了该方法的鲁棒性和有效性。与其他算法相比,该方法即使在检测概率降低和杂波率升高的情况下也表现出更强的鲁棒性。
