摘要:

PHD滤波是一种常见且有效的多目标跟踪(MOT)算法,用于对象数量及其状态未知的场景。在每个对象每次扫描可以生成多个测量结果的情况下,一些PHD滤波器可以估计对象的范围以及它们的运动学特性。然而,这些方法中的大多数不能固有地估计轨迹,并且依赖于诸如不同标记方案的自组织方法来从状态估计构建轨迹。本文提出了一种Gamma高斯逆Wishart混合PHD滤波器,可以直接估计扩展目标的轨迹集,通过扩展以前的研究跟踪点源对象的轨迹集处理扩展对象。新的过滤器相比,现有的扩展PHD过滤器,使用标签计划来建立轨迹,它表明,新的过滤器可以更可靠地估计对象的轨迹。

英文摘要:

PHD filtering is a common and effective multiple object tracking (MOT) algorithm used in scenarios where the number of objects and their states are unknown. In scenarios where each object can generate multiple measurements per scan, some PHD filters can estimate the extent of the objects as well as their kinematic properties. Most of these approaches are, however, not able to inherently estimate trajectories and rely on ad-hoc methods, such as different labeling schemes, to build trajectories from the state estimates. This paper presents a Gamma Gaussian inverse Wishart mixture PHD filter that can directly estimate sets of trajectories of extended targets by expanding previous research on tracking sets of trajectories for point source objects to handle extended objects. The new filter is compared to an existing extended PHD filter that uses a labeling scheme to build trajectories, and it is shown that the new filter can estimate object trajectories more reliably.
