Exploration of Photometric Stereo Technology Applies to 3D Model Reconstruction (original) (raw)

An efficient method has been presented to achieve an accurate dense 3D reconstruction of objects using photometric stereo technology. The task of recovering three-dimensional geometry from two dimensional views of a scene is called 3D reconstruction. Photometric Stereo is a powerful image based 3D reconstruction technique that has recently been used to obtain very high quality reconstructions. The Photometric Stereo (PS) technique uses several images of the same surface taken from the same viewpoint but under illuminations with different directions. The illumination conditions refer to the light source direction and intensity, and reflectance properties mean what type of surface is under consideration i.e. Lambertian or non-Lambertian. . The algorithm has been tested on synthetic as well as real datasets and very encouraging results have been obtained.
