粒子滤波算法重采样门限值研究

目标跟踪算法的目的是对目标进行跟踪,跟踪滤波算法的好坏直接决定了能否及时地跟踪上目标。在粒子滤波算法中,重采样是很重要的一步,很多介绍粒子滤波的文献都提到了在重采样前设置一个采样门限,以此来判断在粒子滤波算法中是否进行重采样。采用实际仿真的方法研究了采样门限取值对跟踪效果包括跟踪时间以及跟踪精度的影响,采用了最经典常用的跟踪模型进行了仿真研究。

The Research on the Value of Re-sampling Threshold in Particle Filter Algorithm

The purpose of the target tracking algorithm is to track the target,the efficiedncy of the tracking filter algorithm determines directly whether the target could be tracked timely. In particle filter algorithm, re-sampling is a very important step. Many literatures introducing the particle filter mention that a sampling threshold should be set up before re-sampling, and accordingly make a judgment about whether or not the re-sampling should be conducted in particle filter algorithm. Adopting the actual samp...
