This paper proposes a new methodology of stereo vision: the subpixel stereo method. The method controls the disparity less than one pixel with very small baseline length. Although the accuracy of measured distance is not high, this method is effective for robot vision because of the avoidance of the false correspondence problem, and simple high speed operation. Applications of the method to low resolution image and to the active method are also discussed.
