The new method for noncontact measurement of 3D surface of the diffuse reflecting objects based on multi directional fringe projection and joint processing of the captured images by a method of Fourier-synthesis is presented. This method allows to increase the spatial resolution of a reconstructed 3D object surface on all directions and simultaneously to reduce shaded area on object.
