3-D Profile Measurement for Robot-based Manufacturing Visualization System

In this paper,Fourier transform profilometry is applied to obtain the 3D profile of parts,and the main purpose is to develop real time measuring and control system provided that the certain precision of the method is kept,thus to control the growth of the coating and improve its quality.The phase measurement principle of the method,the relationship between object profile and the required phase are addressed in detail.The system structure of the 3D measurement is also set up.The experimental results based on the method are given at the end,and also the error sources and improvement methods are brought forward.
