Abstract


Improvement of tracking accuracy is an important issue when applying augmented reality to nuclear power plant field work. Tracking accuracy depends highly on the marker arrangement when employing a tracking method using a camera and markers. For those reasons, this study develops a wheel tracking error computation method to compute the tracking error from the marker arrangement and errors in the screen coordinate. An evaluation experiment was conducted using a kind of linecode markers developed before. Experimental results show that the tracking error computation is reliable and the speed of the tracking error computation is affordable to be applied in real time error estimation in NPP field work support.
