CALIBRATION OF INITIAL ORIENTATION AND POSITION OF SPORTS EQUIPMENT AND BODY SEGMENTS FOR INERTIAL SENSORS

摘要

A system and method for calibrating an inertial motion sensor attached to an article of sports equipment or to a body segment in accordance with the user's initial orientation and location at the beginning of a sports motion. The sensor captures real-time motion data and the calibrated initial orientation and location provide absolute heading angle and starting position of the equipment or body segment in a spatial frame. Subsequent motion data within the spatial frame can be accurately analyzed so that three dimensional trajectory of the equipment or body segment can be precisely determined and presented in an animated playing environment on devices such as smartphones, tablets and laptops.
