1、卡尔曼滤波的简单例子 kf_wendu.py 一维的数据进行卡尔曼滤波,简单的温度检测

2、kf_x_v.py 二维数据(x,v)进行卡尔曼滤波,或者可以叫数据融合,转载自下链接 https://github.com/liuchangji/2D-Kalman-Filter-Example_Dr_CAN_in_python

其实通过调整过程噪声和测量噪声可以发现,当测量噪声方差较小时,后验数据更接近测量值, 当把测量噪声方差调大时,因为有先验的缘故,后验数据也并没有像测量数据那样偏的很大

3、imu+gps+ekf

可以看到随着时间的增加,带噪声的推算已经和真实值偏差越来越大,但是ekf融合后接近真实值,ekfyyds
