Automated Profilometry of 3-D Diffuse Objects byUsing Cosine Transformation
A new method of automatitally reconstructing the 3-D surface of an objectfrom the deformed grating pettern is proposed. The method can automatically andaccurately obtain phase value at every pixel point without assigning fringe orders by usinga discrete cosine transform algorithm. It is flee from the errors caused by the higherharmonic components and the variation of light level. Theoretical analysis andexperimental verification are presented.
