Paper Abstract

Three-dimensional (3D) shape measurement can be accurately performed using sinusoid grating projection. However, the projection technique requires very accurate phase shifting of the grating. A method for phase shifting calibration which utilizes gray value correlation of image patterns is presented. The method enables calibration to be performed at sub-pixel accuracy. Experiments were carried out to verify the proposed calibration method.
