摘要
将径向速度引入到自适应网格交互多模型算法中,并针对自适应网格算法在跟踪过程中网格中心不稳定的问题增添模型集改变阈值,提出了一种修正的自适应网格交互多模型算法。同时对一些关键参数作了深入研究。仿真表明,提出的修正算法提高了算法稳定性,增强了模型滤波器与真实运动模式的匹配程度,减小了跟踪的速度误差和距离误差,很好地改善了跟踪性能,并具有全面自适应的跟踪能力。
A modified adaptive grid interacting multiple model algorithm is proposed that the radial velocity is introduced into the adaptive grid interacting multiple model algorithm,and models changing threshold adds to adaptive grid interacting algorithm to solve the problem of instability of the grid center in the tracking process. Some of the key parameters of the algorithm is made an in-depth study . Simulation results show that the modified algorithm can improve the algorithm stability,and enhance the matching degree between the model filter and the real sports mode,reducing the tracking speed error and distance error and improve the tracking performance,and the modified algorithm has a comprehensive adaptive tracking capability.
