Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a method that combines Temporal modified RANSAC and Graph-cut utilizing color, structure and A-priori Probabilities. This method can discriminate each moving object from the still background, can compute the stereo cameras’ egomotion, and can reconstruct 3D structure of each moving object and static background. Our Temporal modified RANSAC segments the detected 3D optical flows into moving objects and background and computes the rotation and translation matrix for each object. Next, 3d points computed from stereo images segmented into each moving object or static background by Graph-cut. Finally, the 3D points are registered using each object’s matrix to the initial positions so that the 3D structures of the moving objects and still background are reconstructed. Experiments using multiple moving objects and real stereo sequences demonstrate the effectiveness of our proposed method.
