535 Optical Three Dimensional Measurement System Controlled by Robot Arm

Abstract

A three-dimensional shapes measuring system using an optical spatial modulator have been proposed. The system is composed of an optical spatial modulator from which grating patterns are projected on the surface of the object, a CCD camera controlled by a robot arm, and a computer. The patterns on the surface of the object were taken into the computer by the CCD camera, and the 3D coordinate of the surface of the object was calculated. The system was improved using mechanical and optical method and data analysis.
