The embodiment of the invention discloses a parallax correction method, device and terminal. The method comprises: acquiring a point to be filtered in a parallax image, determining a filtering windowsize according to the parallax value of the point to be filtered, wherein the size is positively correlated with the parallax value; determining the filtering window of the point to be filtered and updating the parallax value of the point to be filtered according to the parallax value of the valid parallax point in the filtering window. Since the filtering window size can be set to be positively correlated with the parallax value of the point to be filtered, in view that the parallax value is inversely proportional to the distance and the different filtering effects are required according to different distances, and the closer the distance is, the larger the filtering window of the point to be filtered is, and the farther the distance is, the smaller the filtering window of the point to befiltered is. When the parallax value of the point to be filtered is corrected, the filtering effect of the parallax points at different distances can be well balanced according to the parallax valuesof other valid parallax points in the filtering window, thereby effectively smoothing the parallax image and reducing the late detection and recognition difficulty.
