A simple method to generate pseudo-solid texture map of a 3-D digital image is described. The geometric shape of 3-D image is reconstructed from the digital moire topographic system. The pseudo-solid texture mapping is accomplished by acquiring the deformed carrier fringe pattern, and then followed by a procedure of removing the spatial carrier and implementing a geometric mapping from gray-scale image (2D texture) to 3D reconstructed digital image. The unique feature of this method is that only single step acquisition is needed to obtain both geometric shape and texture information of 3-D object surface and it does not require any scanning mechanisms during the image acquisition. Experimental results are presented to illustrate the validity of simultaneous texture extraction using proposed method and show the natural 3-D texture representation of a real, free-from object surface without any visual distortion.
