A method is presented for the recovery of the 3D motion parameters of a rigidly moving textured surface. The novelty of the method is based on the following two facts 1 no point-to-point correspondences are used, and 2 stereo and motion are combined in such a way that no correspondence between the left and the right stereo pairs is required. An important problem in Computer Vision is to recover the 3-D motion of a moving object form its successive images. Dynamic visual information can be produced by a sensor moving through the environment andor by independently moving objects in the observers visual field. The interpretation of such dynamic imagery information information consists of dynamics segmentation, recovery of the 3-D motion of the sensor and the objects in the environment as well as determination of the structure of the environmental world. The results of such an interpretation can be used to control behavior as for example in robotics, tracking, and autonomous navigation.
