Im struggling on a simple assignment. The equations of the Kalman filter can be categorized into two groups: time update equations and measurement update equations. Kalman Filter Cycle: To take account of the non-linear models the equations for the filter cycle are slightly modified. Use an extended Kalman filter when object motion follows a nonlinear state equation or when the measurements are nonlinear functions of the state. The filter then uses the newly detected location to correct the state, producing a filtered location. This example shows how to use 6-axis and 9-axis fusion algorithms to compute orientation.
