卡尔曼滤波是一种高效率的递归滤波器(自回归滤波器), 它能够从一系列的不完全包含噪声的测量(英文:measurement)中,估计动态系统的状态。这种滤波方法以它的发明者鲁道夫.E.卡尔曼(Rudolf E. Kalman)命名。然而简单的卡尔曼滤波必须应用在符合高斯分布的系统中,后期的学者对其进行了多方面的改进,其中之一就是扩展卡尔曼滤波,可应用于时间非线性的动态系统
The Kalman filter is an efficient recursive filter that estimates the state of a linear dynamic system from a series of noisy measurements. It is used in a wide range of engineering applications from radar to computer vision, and is an important topic in
