WebbImplementation of Kalman Filter with Python Language Mohamed LAARAIEDH IETR Labs, University of Rennes 1 [email protected] Abstract In this paper, we investigate the implementation of a Python code for a Kalman Filter using the Numpy package. A Kalman Filtering is carried out in two steps: Prediction and Update. WebbIn Kalman filters, we iterate measurement(measurement update) and motion (prediction). And the update will use Bayes rule, which is nothing else but a product or a multiplication.
