所以可以完全套用前面的框架,就可以得到我们在加性条件下的预测步更新步啊这,这不就跟我们之前卡尔曼滤波的假设很相似吗?所以可以完全套用前面的框架,就可以得到我们在加性条件下的EKF:预测步:mk−=f(mk−1),Pk−=Fx(mk−1)Pk−1Fx⊤(mk−1)+Qk−1.更新步:vk=yk−h(mk−...
一、扩展卡尔曼滤波(EKF)简介 扩展卡尔曼滤波(Extended Kalman Filter)是建立在经典卡尔曼滤波算法的基础上。核心思想是,对一般非线性系统,首先围绕滤波值Xk~将非线性函数f(∗)和h(∗)展开成Taylor级数但只保存一阶及以下部分(舍去二阶及以上项),得到近似的线性化模型。然后就是利用kalman滤波算法完成对目标的...
This is a sensor fusion localization with Extended Kalman Filter(EKF).The blue line is true trajectory, the black line is dead reckoning trajectory,the green point is positioning observation (ex. GPS), and the red line is estimated trajectory with EKF....
