Paper Abstract

In this work, an optical system for digitizing 3D objects by using structured light is described. It is fast, contactless, highly accurate and it can work in strongly illuminated environments. An application for an industrial quality control set-up is presented, in which sand cores to be used in the car industry are automatically handled by a robot and analyzed by the 3D digitizer. After the analysis of each core presented by the robot, the digitizer sends an OK or KO instruction for the faultless or faulty piece to be placed by the robot in a different area. In order to perform all the calculations required for the analysis and for the hardware control, a specific software has been developed. A series of examples and result are shown with comments on the advantages of the method here described.
