1823 本文提出了一种分散式大规模多目标跟踪网络的传感器选择优化算法。 A sensor selection optimization algorithm is proposed for decentralized large-scale multi-target trackingnetwork.
1824 该方法以多目标状态集和估计集间的均方最优子模式分配误差下界作为优化目标函数,根据加权 Kullback-Leibler 平均(Kullback-Leibler average,KLA)准则对局部多目标密度进行融合,最终采用坐标下降法来折中计算代价和跟踪精度。 In this method, the lower bound of mean square optimal sub-pattern assignment error between multi-target state setand its estimation is taken as optimized objective function while the rule of weighted Kullback-Leibler average (KLA)isused to fuse local multi-target densities. The coordinate descent method is proposed to compromise the computation cost andtracking accuracy.
