Calibration of a fringe projection profilometry system using virtual phase calibrating model planes

A novel virtual phase calibrating model plane method for coordinate calibration in fringe projection profilometry is presented in this paper. Plane (X-axis and Y-axis) calibration and height (Z-axis) calibration are studied respectively. The virtual phase calibrating model plane method is designed to calibrate the coordinates. Experimental results show that the proposed calibration procedure using the virtual phase calibrating model plane method is more efficient in that it needs only to grab and process one series of images of the model plane, whereas the traditional calibration method requires at least two series of images.
