To maintain the safety operation for the crane track, it is important to measure the high accurate three-dimensional position of a crane hook. However, it is not easy to obtain the position information of the swinging crane hook by using sensors. In this paper, we introduce the measurement method of three-dimensional position of the moving crane hook based on the image data obtained by one single camera. First, we treat the detection method of the area of the crane hook by using the optical flow, and then track the detected area based on orientation code matching. Through the experimental results, we show the usefulness of our proposed method.
