| 摘 要： | 针对系统误差变化规律未知时的传感器探测系统偏差估计问题,提出了一种改进的基于Mean-Shift(均值偏移)的传感器动态偏差估计算法.该算法利用Mean-Shift方法对不同样本点对估计结果贡献不同的特点,根据样本点偏离均值的偏移量以及偏移时间构建权系数.仿真结果表明,该方法在系统误差变化规律未知的情况下,可有效估计多...

| Abstract: | For the time-variant registration errors of multi-sensor fusion tracking system in practical applications,an bias estimation algorithm based on Mean-Shift is proposed.This method emploed the character of mean-shift that different sample contribute different for estimation,and weight coefficient establised by sample time and the difference between sample and mean.This algorithm avoids the influence of random noise and abnomal sample,and can get more moderate estimation,the simulation results proved the effec... |
