View Full Version : Kalman Filter

Feb 15, 2007, 03:46 PM
Hello everyone.

I am doing some research into advanced robotic behaviour and something that keeps coming up alot is the Kalman Filter. I know it is also used with computer graphics.

Does anyone know anything about the Kalman Filter? Also anything that is not aimed at degree level maths would be useful!

A Kalman Filter (http://en.wikipedia.org/wiki/Kalman_filter) is a way to incorporate imperfect measurements of something, and use them to predict future state. For example, you could take position measurements of a boat, and in conjunction with a rough model of the behavior of the boat (say it is moving roughly in a straight line with a slowly-changing speed), you can predict where it will be as time goes on.
