Entire Object Reconstruction Using a Rotational Stage

This paper presents a method for reconstruction of entire three-dimensional objects based on principles of the rotational stereo. The experimental system, which has three degrees of freedom (two for translation and one for rotation), uses an accurate stage to make all areas of the object surface visible. It only needs one camera to capture images and thus reduces the implementation cost. The object to be reconstructed is placed on a rotational device which can be precisely controlled by a computer. A series of images are easy to be obtained for recovering the complete model of the object. A few examples are carried out in the experiments. Results are very satisfactory in mean of both feasibility and accuracy.
