This invention discloses an online thickness measurement method for evaluating surface step difference in the sunken area after mirror milling of a skin. First, the coordinates and corresponding thickness values ​​of ordered spatial points are read. Noisy coordinates and thickness data are filtered out using a thickness threshold condition. Then, for the valid data, the tangential angle value of each point is calculated sequentially. Next, using the tangential angle value and the coordinate difference between different points as judgment conditions, all ordered spatial points are labeled into four types: horizontal lines, vertical lines, diagonal lines, and rounded lines. Nearest neighbor points are found among feature points with different numbers within each of the four feature types. The absolute value of the thickness difference between feature points that meet the nearest neighbor requirement is used as the left or right step difference value for each point. The left and right step differences of the ordered spatial points are calculated sequentially. The step difference value of each point is equal to the larger of the left and right step differences.
