We propose a calibration method of a fringe projection system for surface profile measurement. The calibration method is divided into two parts: (1) phase to calibration based on measuring the absolute phase distributions of a flat calibration board placed at several different known positions. (2) Camera calibration based on Zhang’s method of imaging a checkerboard with different poses. Experiments of a flat plane, a sphere, and a Gorky sculpture demonstrate the validity and accuracy of the proposed technique.
