Abstract
To recover 3-D shapes, a new algorithm which is based on the hybrid reflectance model and the indirect diffuse illumination method is presented. The photometric stereo method (PSM) is modified with the indirect diffuse illumination method (IDIM). We derive the surface reflectance function for a disk-type light source and make the 3-D reference table generated by applying the derived surface reflectance function to the hemisphere. The slant and tilt angle at each point of the intensity images which are the inputs for the algorithm is determined from the 3-D reference table. Finally, the 3-D shape of objects is recovered from the needle map.
