Abstract

In fringe projection profilometry, the lens distortion of a commercial projector may introduce larger error when testing large objects and can become one of the major error sources. In this paper, a calibration method for a fringe projection system is adapted in order to remove the influence of projector lens distortion without the need to calibrate the projector. In the proposed method, the accuracy of the fringe projection system has a considerable improvement because an adaptive fringe pattern is calculated in order to compensate for all possible distortions generated by the projector.
