Abstract
The marker has thereon one three-dimensional indicator. Based on the location and height of the three-dimensional indicatorrelative to the plane indicatoras well as the estimated position of the camera relative to the marker, the center positions of the upper face and the lower face of the three-dimensional indicatoron the image of the camera are estimated. The estimated center position of the upper face of the three-dimensional indicatoris compared with that detected from the image. When the error between them has a value equal to or higher than a predetermined value, based on the posture estimated, a rotational transformation is carried out.
