Research Abstract

Estimation of the shape from grayscale images under different lighting conditions was studied in order to establish photometric stereo with perspective projection model and two point light sources. Several methods were proposed to recover the relative size of Gaussian curvature on an object with color textures and specular reflectance component, and to reconstruct the shape of the object with specular reflection by FMM and self-calibration. The structure of equipment was designed to perform continuous shooting a real object under two light sources in anticipation of its application to endoscope.
