分布式多目标跟踪系统的灰色航迹关联模型

本文以分布式多目标跟踪系统的航迹关联问题为研究对象,首先指出了现有的两类航迹关联算法的固有缺 点,然后基于灰色理论提出了一种新的航迹关联算法,该算法根据数据列因素之间发展态势的相似或相异程度来衡量航迹 间接近的程度,使航迹关联问题突破了样本容量和典型分布这两条限制。最后给出了典型环境下的仿真结果,并与加权法 进行了比较,显示了该算法的优越性。

Gray Track Correlation Model for Distributed Multitarget Tracking System

This paper mainly discusses the track association problem for the distributed multitarget tracking system. First, the inherent disadvantages of the present two class of track association algorithm are pointed out. Then a novel track association algorithm based on the gray theory is presented. This method can weigh the degree of relative correlation by the developing situation between the factors in the data sequence, which breaks through the limitations of the sample quantities and the typical distributing rule. At last, the simulation results under the typical environment are given. The comparison between the output of the proposed algorithm and the weight track association show its advantage.
