EXTENDED KALMAN

hey guys ,
me rondevu sabzi ...
currently m stuck up in a situation...
i've been given a project wherein i've to implement multi sensor data fusion using 'extended kalman filters' IN 'matlab or c'....
the results regarding any insight on this topic will be highly appreciated..
THANKX :?:

Re: EXTENDED KALMAN

I am not sure what kind of information you are looking for, but I implemented a simple kalman filter in c a few months ago.

Here is a brief and very simple insight:
You use information from two sensors. For example for a more precise positioning of a car you use the GPS signals to give you an approximate measurement of the location of the car and you can use an accelerometer in the car to get the relative movement from the last position.
Kalman filter is a way to combine these two sensor to produce an accurate positioning.
