In order to avoid sub-optimal performance, the unscented Kalman filter is chosen, while a new curvilinear model is applied which takes into account both the turn rate of the detected object and its tangential acceleration, leading to a more accurate modeling of its movement. The performance of ...

Kalman Filter是处理连续变化的动态不确定系统的理想方法,并且由于内存占用小(不需要记录历史状态),运行速度快,被广泛应用在机器人实时多传感器融合系统中。 What can we do with a Kalman filter 首先看一个简单的例子: 假设有一个可以在树林中自由漫步的机器人,这个机器人配备了一个精度为10m的GPS传感器和自身状...
Kalman Filter 卡尔曼滤波主要分为两步: 预测(根据运动方程获取预测值) 纠正(根据观测方程纠正预测值) 运动模型(Process/Motion model): (1)xk=Fk−1xk−1+Gk−1uk−1+Wk−1 其中Wk−1为运动噪声,其满足wk−1∼N(0,Qk)。 观测模型(Measurement model): ...
Kalman Filter 与 Recursive Least Square Least Square 解决的是静态参数估计的问题,Kalman Filter 可以解决动态变化的状态的估计和更新问题。 对比KF 与 RLS 的过程: KF: 预测 测量更新 RLS: 可以看出,KF 比 RLS 相比,增加了基于 Motion Model 的 Prediction 过程,用于跟踪 State 是如何随时间变化的。
These can accurately track movement based on adaptive filtering by using a state-space model. To use the Kalman filter for the tracking of moving objects, it is necessary to design a dynamic model of target motion. The most common dynamic model is a constant velocity (CV) model [1, 10],...
