| Abstract: | According to the complicated manufacturing technique of sinusoidal grating in Phase measuring profilometry(PMP),the paper presents a new method to measure the 3D shape based on the triangular-pattern grating.When measuring,the triangular-pattern grating was projected to the surface of the object,and the camera captures the stripes image.The 3D shape of the object may be reconstructed by the phase information that the fringe pattern carries.Some calculation formulas for phase and height are derived.The experimental results show that the method is reliable,and can carry out 3D shape measuring with high precision. |
