Abstract
The Digital Projection Speckle Correlation Method (DPSCM) is a non-contact full-field optical 3D profile and deformation measurement technique, which combines with 2D Digital Image Correlation Method (DICM), using LCD projector to produce random speckle that is projected on the surface of the sample.In this paper,the 3D profile and deformation measurement experiment of large-scale objects is finished by DPSCM,and the factor which influences the result of experiment is also discussed
