SYSTEM AND METHOD FOR PORTABLE ELECTRONIC DEVICE THAT DETECT ATTITUDE AND ANGULAR VELOCITY USING MAGNETIC SENSOR AND ACCELEROMETER

摘要

PROBLEM TO BE SOLVED: To provide a system which determines motion information including a dynamic attitude and an angular velocity of a body.;SOLUTION: The system includes a magnetic field detection device 71 which measures intensities and/or directions of a magnetic field in three substantially orthogonal directions on a main-body reference coordinate system; an acceleration detection device 72 which is adapted to measure all accelerations of the body on the main-body reference coordinate system; and a processor 75 which calculates an attitude and an angular velocity by combining measurement data on all the accelerations, measurement data on the magnetic field, and a kinematical model in a filter.;COPYRIGHT: (C)2013,JPO&INPIT
