Recently, we have proposed the freehand scanning method for measuring
field distribution using a magnetic tracker to determine
the position of EMF sensor. However, a magnetic tracker cannot
obtain correct location data if there are some metals around
measurement area though it has enough accuracy for determining
the position.
In this study, an optical tracker that consists of the USB camera
and PC with OpenCV is used instead of a magnetic tracker to determine
the measurement position. As a result, it is found that
an optical tracker is useful for the real-time, rough measurement
of 2-D field distribution. |
