Topometry and color association by RGB fringe projection technique

Abstract

Three-dimensional object topography is obtained by using the fringe projection technique. In fringe projection technique, digitalization is done when black and white lines are projected over the sample object and the image is captured by the CCD. It is applied the phase shifting method to evaluate the phase of the projected fringes. In this paper it is proposed a method in which red, green and blue fringes are projected sequentially. It is obtained the topography to each color (RGB) and finally the three obtained shapes are averaged. By using this method, we obtain information about color, texture and topography details of the object.
