CALIBRATION METHOD AND CALIBRATION DEVICE OF BRAIN MAGNETIC FIELD MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To simply and easily and precisely calibrate the coordinate system of a motion capture device.;SOLUTION: A calibration method is characterized by including following steps. 1. a step for arranging a calibration device in an inserting hole of an object to be measured of a dewar helmet in 2. a step for energizing each of calibration coils constituting the calibration device and calculating the position of each of the calibration coils in the inserting hole of the object to be measured of the dewar helmet. 3, a step for calculating the position of each of the calibration coils 18 by the motion capture device constituted of a camera and a motion capture control PC. 4. a step for calibrating the motion capture device using the position coordinate of each of the calibration coils in the inserting hole of the object to be measured of the dewar helmet calculated in the step 2 as the positions of the calibration coils calculated by the motion capture device.;COPYRIGHT: (C)2012,JPO&INPIT
