Abstract:
A method, apparatus, and device for obtaining a disparity map, a control system, and a storage medium, relating to the technical field of image processing. The method comprises: respectively performing, layer by layer, feature extraction on a left eye image and a right eye image of a photographed object by means of M cascaded feature extraction layers, to obtain a left eye feature map set and a right eye feature map set of each layer (601), wherein M is a positive integer greater than or equal to 2; constructing an initial disparity map on the basis of the left eye feature map set and the right eye feature map set extracted by the Mth feature extraction layer (602); and starting from the (M-1)th layer, sequentially performing iterative updating on the disparity map by means of the left eye feature map set and the right eye feature map set extracted by each feature extraction layer until a final disparity map is obtained on the basis of the disparity map iteratively updated by the first layer (603).
