from filterpy.kalman import KalmanFilter f KalmanFilter (dimx2, dimz1) Assign the initial value for the state (position and velocity). First construct the object with the required dimensionality. However, neither example has any kind of calculation $(x_k-x_)/dt$ for speed, in fact it is hidden in there after all. Here is a filter that tracks position and velocity using a sensor that only reads position. With my improved understanding of what's going on, I've now redrafted the question and focused it more tightly.īoth examples that I refer to in the introductory paragraph above assume that it's only position that's measured.

Sensor readings captured in input text file are in below format. But with our current understanding of Kalman Filter equations, just using Laser readings will serve as a perfect example to cement our concept with help of coding.

Update 2: the original question here contained some errors, related to the fact that I hadn't properly understood the the wikipedia example on one dimensional position and velocity. Once we cover ‘Extended Kalman Filter’ in future post, we will start using Radar readings too. I've been looking at what was recommended, and in particular at both (a) the wikipedia example on one dimensional position and velocity and also another website that considers a similar thing. Thanks to everyone who posted comments/answers to my query yesterday (Implementing a Kalman filter for position, velocity, acceleration).Ive been looking at what was recommended, and in particular at both (a) the wikipedia example on one dimensional position and velocity and also another website that considers a similar thing.
