Paper Abstract

This paper is based on the triangulation method and the random digital speckles are projected on the reference plane and the surface of the object, with the digital speckle correlation principle, solving the height of object and reconstructing three-dimension of the object. Experimental results indicate that the digital speckle correlation technology in the measurement of three-dimensional objects is validity, reliability.
