We propose a new method for disparity assisted stereo optical flow estimation. This method is based on the linearization of the round-about compatibility constraint, which converts a stereo optical flow estimation problem to a single channel optical flow estimation problem. An over-determined system of optical flow equations can then be constructed for estimating the flow fields. The total least squares, instead of the traditional least squares is used to solve the estimation problem. We also investigate the extension of the locally constant flow model across the time domain. The experiments presented demonstrate that the proposed technique performs very well
