%X For un-calibrated parallel cameras,a new algorithm using affine transformation is proposed in this paper.This algorithm uses Harris operator to obtain corners,and determines corresponding image points with characteristic tracking method,and segments affine transform theory,and then constructs the affine matrix to make disparity block estimation.It has been proved that the algorithm can improve the result of the original motion estimation.
