基于似然的航迹关联算法研究

摘要

文章以分布式多目标跟踪系统的航迹关联问题为研究对象，提出了四种基于似然的航迹关联算法，这两种算法通过建立似然函数来反应航迹间的相似程度，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两种似然航迹关联算法的仿真，结果表明基于似然理论的航迹关联准则，能够达到比较满意的关联效果，体现了似然理论在解决航迹关联问题时的优良特性。%This paper mainly discusses the track association problem for the distributed multitarget tracking system, then two kinds oftrack association algorithms based on likelihood are presented, this method can weigh the degree of relative correlation by building likelihood function, which breaks through the limitations of the sample quantities and the typical distributing rule, at last, the simulations under thetypical environment are given, the results shows that the decision based on likelihood theory can reach a satisfying conclusion,which embodies the perfect properties of likelihood theory in solving track association problem.
