Abstract :
This paper proposes a way to measure distance between a camera and marker using monotone cubic hermite interpolation and marker recognition. After vertex point of the marker at the image obtained from the camera, the marker using Counter-Clock-Wise (CCW) algorithm is detected and the size of this is saved. The distance value about the marker size is calculated by using hermite interpolation. By comparing new marker size and the values calculated, the distance is decided by the closest value. The experimental results show that the proposed method is effective at processing time and accuracy and shows error rate under 5 percent.
