3D Shape Reconstruction using Stereo Image Scanner

Abstract

In this paper, we propose a shape reconstruction method combining a binocular stereo method and a photometric stereo method with three light sources. From a stereo images taken by a stereo image scanner, first, we estimate heights at edge points on the object by the binocular stereo method. Next, we obtain the albedo on the object surface near edge points by using estimated height. And we recover the object shape by the photometric stereo method with estimated albedos. In the experimental results, we show the effectiveness of the proposed method by recovering a cylindrical object shape from real stereo images.
