FIG 3 (IMAGE) Compuscript Ltd Caption Experimental scheme of 3D reconstruction about the high-contrast object with complex surface. (a) The 3D reconstruction scheme relies on discretizing the target object into 2D slices with small gaps between them. (b) Contour information contained in every slice of an observed object would be captured. (c) The 3D model is reconstructed by recombining the different projection results captured in Fig. (b). (d)-(f) Original and 3D experimental reconstruction models of grooves, landings, and bosses, respectively. Credit OEA Usage Restrictions Credit must be given to the creator.
