METHOD FOR CALIBATING ORIENTATION MEASUREMENT SENSOR, APPARATUS FOR CALIBATING ORIENTATION MEASUREMENT SENSOR, MOBILE ELECTRONIC DEVICE COMPRISING THE SAME AND PROGRAM RECORDING MEDIUM

摘要

The present invention relates to a method of calibrating an orientation measurement sensor. A method of calibrating an orientation measurement apparatus according to an embodiment of the present invention comprises the steps of: (a) obtaining a first orientation value corresponding to a relative orientation of a first orientation measurement sensor with respect to a first reference coordinate system; (b) obtaining a second orientation value corresponding to a relative orientation of a second orientation measurement sensor with respect to a second reference coordinate system; and (c) calculating a third orientation value corresponding to the relative orientation of the second orientation measurement sensor with respect to the first orientation measurement sensor and a fourth orientation value corresponding to a relative orientation of the second reference coordinate system with respect to the first reference coordinate system, using the first orientation value and the second orientation value, with a calculation apparatus. The step (c) corresponds to the step of calculating the third orientation value and the fourth orientation value, which minimize an error between a fifth orientation value corresponding to a relative orientation of the second orientation measurement sensor with respect to the first reference coordinate system calculated from the first orientation value and the third orientation value, and a sixth orientation value corresponding to a relative orientation of the second orientation measurement sensor with respect to the first reference coordinate system calculated from the second orientation value and the fourth orientation value.
