Abstract

An impact motion tracking system for tracking an object in a three-dimensional space includes a motion tracking sensor that includes a housing, a magnetic measurement module, an inertial measurement module, and a transmitter module, which generates magnetic fields. The magnetic measurement module measures magnetic fields generated by the transmitter module and has a fixed orientation with the object. The inertial measurement module measures a linear acceleration or an angular acceleration and has a fixed positional relationship with the object. An electronic processor receives measured signals from the motion tracking sensor and derives an impact motion information for the object based on received measured signals from the inertial measurement module. The electronic processor derives a magnetic motion information for the object based on received measured signals from the magnetic measurement module and periodically calibrates impact motion information with magnetic motion information.
