摘要： 在目标跟踪研究中,大量的实验证明粒子滤波算法对于运动轨迹变化复杂的运动目标跟踪效果不理想.基于变率粒子滤波算法(VRPF),以大型建筑灾难救援系统为研究背景,应用无线传感器网络技术,提出了一种自适应变率粒子滤波算法(AVRPF).该算法通过比较某时刻粒子值与测量值的关系自适应地调节采样周期,以提高对复杂运动目标的跟踪精度,尤其当运动轨迹出现大幅度变化时.仿真实验证明了该算法的有效性和实用性.

Abstract: In the research on target tracking, lots of experimental results illustrated that the particle filter algorithm is imperfect to the moving target of which the trajectory changes complexly. The AVRPF (adaptive variable rate particle filter) algorithm is proposed instead of VRPF (variable rate particle filter) algorithm in regard to the rescue system for large-scale building during disaster, with the wireless sensor network technology applied to the system. The AVRPF can adaptively adjust the sampling period by comparing the relationships between the particle value and measured value at a certain moment to improve the tracking accuracy for complex moving target, especially the moving trajectory changes dramatically. The simulation results showed that the tracking algorithm is effective and practical.
