The authors propose a method to measure the smooth curvedsurface of an object and the depressed surface of an object whichcannot be measured using the visual hull method by using a needlediagram obtained via photometric stereo. Errors occur in thedistance map as a result of depth edges when recovering a distancemap using a needle diagram. In order to reduce these errors, thesilhouettes from other directions are used. The distance maprestored without taking into consideration the depth edges oftenlacks consistency with the silhouettes obtained from otherdirections. The authors take advantage of this feature, define theenergy representing the consistency between the distance map andthe silhouette as well as the consistency between the distance mapand the needle diagram, and then reduce the errors in the distancemap by obtaining a distance map which minimizes this energy.Through experiments using the proposed method on simulation dataand a real object, the authors evaluate the effectiveness of theproposed method. © 2007 Wiley Periodicals, Inc.
