| description | The invention relates to a projection image automatic correction method and system based on binocular vision. The method comprises the steps of acquiring a depth map of a projection image on a projection plane; calculating a first transformation relationship between the source image and the projection image; obtaining a distorted image according to the depth map; obtaining a corrected image afterthe distortion image is corrected; calculating a second transformation relationship between the distorted image and the corrected image; obtaining a correction relationship between the source image and the corrected image according to the first transformation relationship and the second transformation relationship; and correcting the projection image according to the correction relationship. The method is used for realizing efficient automatic correction of the projection image, is not limited by the projection area, and is high in correction flexibility.
