Abstract
A method of assisting the optical inspection of an object includes the steps of: determining a first three-dimensional image of the object; determining a first color or grey level two-dimensional image of the object; determining at least one first window (F1) on the first two-dimensional image surrounding a possible defect of the object from the first three-dimensional image and/or from the first two-dimensional image; determining a second two-dimensional image corresponding to the first two-dimensional image outside of the first window and corresponding to a first depth map of the object in the first window; and determining a second three-dimensional image (I3D′) corresponding to the first three-dimensional image having the second two-dimensional image applied thereon.
