In this paper, we propose new measurement technique of whole three dimensional shape for small moving objects. The proposed measurement system is very simple structure with the use of a CCD camera that installed a fish-eye lens and a cylinder that coating mirror inside. The CCD camera is set on the top side of the cylinder, and its optical axis is set to the center of cylinder. A captured image includes two types information. One is direct view of the target, the other is reflected view. These two information are used for measuring the shape of target by means of stereo matching. This proposed method can acquire the shape of target using only single image, so we can obtaine the three dimensional shape with the moving with the use of image sequence.
