Abstract(in English) Because the detection of optical flow from image sequences is an ill-posed problem essentially, most of the conventional method used smoothness constraint for optical flow heuristically and detected the reasonable optical flow. However, there has been litle argument about the degree of the smoothness. Furthermore, to recover the relative 3-D motion and depth between camera and rigid object, generally at first, the optical flow is detected without the rigid motion constraint, and in the next, the motion and the depth are estimated using the detected optical flow. Properly speaking, hoerver, the optical flow should be detected with such constraint, and consequently the 3-D motion and the depth should be determined.To solve these, in this paper, we apply a parametric model to optical flow, and construct the estimation algorithm based on this model.
