基于最大熵模糊聚類(lèi)的快速多目標(biāo)跟蹤算法研究
[Abstract]:In order to improve the real-time and accuracy of multi-target tracking in clutter environment, the fuzzy membership degree obtained by maximum entropy data fuzzy clustering method is used to express the correlation probability between target and measurement, and the influence of common measurement on target is analyzed. The influence factors are introduced to reconstruct the interconnected probability matrix and the probabilistic data association algorithm is used to realize the multi-objective state estimation. The algorithm avoids the splitting of the confirmation matrix and solves the problem of explosive increase of computation caused by the increase of the number of targets and echoes in the joint probabilistic data association algorithm. The tracking of adjacent parallel targets and small angle cross targets under different clutter density is simulated. The simulation results show that the maximum entropy fuzzy clustering combined probability data association algorithm is an effective and fast data association algorithm. The tracking performance in dense clutter environment is still better than that of joint probabilistic data association algorithm and empirical joint probabilistic data association algorithm, which can avoid track fusion to some extent.
