Self-standing steel chimney design data enhancement method

The invention relates to the technical field of image processing, in particular to a self-standing steel chimney design data enhancement method. The method comprises the steps of obtaining an initial image of a self-supporting steel chimney area, performing down-sampling on the initial image to obtain a down-sampling image, and obtaining a first Hilbert curve corresponding to the initial image and a second interpolation curve corresponding to the down-sampling image; matching each second interpolation curve with the first Hilbert curve to obtain an abnormal point on each second interpolation curve, and constructing a feature point set corresponding to each abnormal point so as to obtain a target value of each abnormal point; and according to the target value and the curve values of the adjacent points on the left side and the right side of the corresponding position of each abnormal point on the first Hilbert curve, determining the weight of the adjacent points on the left side and the right side of the corre
