METHOD AND SYSTEM FOR ESTIMATING A PATH OF A MOBILE ELEMENT OR BODY |
摘要 |
A method for estimating a path of a moving element or body using a sensor assembly includes: receiving acceleration values provided by an accelerometer; receiving angular velocity values provided by a gyrometer; processing the values provided for estimating at least one angular position value using the angular velocity values and at least two Cartesian position values defining a path of the moving element or body using acceleration values and the at least one previously estimated angular position value; estimating rotation parameters, by inverting a rotational realignment model of the estimated path subject to prior knowledge of the path; retroactively correcting the at least one estimated angular position value, by applying a rotation on this value using estimated rotation parameters, so as to provide at least one corrected angular position value. |
