English abstract Three - dimensional object topography is obtained using the fringe projection technique. In fringe projection technique, digitalization is done when black and white fringes are projected over the sample object and the image is captured by the CCD. After that, phases of projected fringes on the surface are evaluated by phase shifting method. This paper presents a proposed method in which red, green and blue fringes are projected. This is very useful when the surface of interest contain large depth discontinuities, because the color encoded stripes avoid losing the fringe order. Doing the phase stepping, topography for each color (RGB) is obtained and the resulting reconstruction is the average of this three images. Using this method, we obtain more information about color, texture and topography details of the object. This method has a lot of applications area, such as archeology and the medical field, because it is possible to duplicate components with major information of color and topography
