摘要
数据关联是实现多目标跟踪的核心技术之一,也是实现多传感器信息融合的前提。本文采用改进的模糊c-均值法求解关联概率,并通过在不同的传感器所对应的观测空间上建立多目标运动状态的投影,将单传感器数据关联算法推广到多传感器信息融合系统,从而可在密集杂波环境中实现对多目标的数据关联和精确跟踪。仿真实验结果说明了本文方法的有效性。
The data association (DA) of track-to-measurement is a kernel problem in the multi-target tracking (MTT) system, and it is also to be the precondition of realizing the multi-sensor information fusion. In this paper, the data association probabilities can be obtained by using the modified fuzzy clustering means (FCMDA) approach, and by means of projecting the target states into the measurement spaces of multi-sensor, the FCMDA algorithm for signal sensor system is extended into the multi-sensor tracking system, and therefore the accurate tracking for multi-targets in heavily cluttered environment can be implemented. The simulation results indicate that the proposed algorithm is very efficient.
