Provided is an optical fringe-pattern noise suppression method based on non-subsampled contourlet transformation. The optical fringe-pattern noise suppression method comprises three steps of optical fringe pattern collection, noise parameter estimation, and non-subsampled contourlet transformation and non-subsampled contourlet transformation coefficient shrinkage. The invention improves the noise suppression effect of conventional optical fringe-pattern noise suppression methods, and realizes effective suppression of optical fringe-pattern noise components.
