Abstract
This paper describes the use of optical fringe projection method for 3D surface profile measurement of object. In this method, sinusoidal linear fringes are projected on the object surface by a programmable liquid crystal display projector. The image of the fringe patter in captured by a CCD camera and processed by phase-shifting techniques. A simple procedure is described which enables calibration of the optical set-up for subsequent quantitative measurement of unknown object shapes. This method is relatively simple and accurate, and is capable of conducting fully automated measurements.
