경면반사체의 3-D비전을 위한 영상처리

Abstract

A method to find the 3-dimensional shape of surface with specular reflection is proposed, where the difference between the images reflected from a flat surface and a curved surface is used. First, these are analyzed the geometric drawing of the spatial reflection at specular surface and the variation of reflected light due to curved surface, whose results are used to find 3-dimensional depth. The proposed method is shown to be effective via experiments using the illumination with spatially distributed light source and CCD camera to capture the light reflected from a surface. In experiments, the captured images from curved surface with specular reflection are compared with the images from flat mirrors.
